Choosing the best natural gas grills comes down to one question most shoppers never ask: do you already have a gas line where the grill will stand? Everything else, burner count, cooking area, sear power, grates, is a decision you can make this afternoon, but the hookup decides whether the grill is even an option. If your home already has a branch line and a shut-off valve outside, you are in the best position of any fuel type.
Our team has spent the last several grilling seasons working through the category from the bottom up, cooking on ten current natural gas models across our own patios and comparing burners, grates, ignition, cleanup, and how each one held up. This guide covers all ten, in the order we would buy them, plus the gas line reality that most roundups skip.
One thing we will say up front: nothing on this list makes food taste better than charcoal. It makes food taste the same as propane with none of the tank hauling, and that is the entire pitch. If you want our broader look at gas grill categories, we have guides to the best Weber gas grills and the best gas grills under 500 dollars for context on where these models sit.

1. Monument Grills 41847NG 4+1 Burner – Our Best Overall Natural Gas Grill
- ✓Even heat with no hot or cold spots
- ✓Stainless body resists rust
- ✓Clearview lid window cuts heat loss
- ✓Side burner keeps heat out of the house
- ✓Convertible to natural gas with the matching kit
- ✕Side burner assembly instructions are confusing
- ✕One four-prong hanger fastener is hard to reach
- ✕Viewing window glass needs frequent cleaning
Four 304 stainless burners plus side burner
60,000 BTU total
510 sq in primary plus 190 sq in warming rack
97 pounds
This is the grill we keep coming back to after a full season of testing. Four 304 stainless steel main burners, a side burner, and a cabinet-style body give it a footprint and cooking surface that outclass most of the grills in this group, and the heat spread across the grate was the most consistent we measured of any convertible model in the group.
Owners consistently point to the even heat, the stainless body that shrugs off weather, and the Clearview lid window that lets you check food without dropping the temperature. Our own read matches that, and the 284 reviews behind its 4.5 average make it the most proven grill on this list.
Burner Layout and Heat Output
The four main burners plus one side burner total 60,000 BTU across a 4+1 configuration. That output spread over 510 square inches of primary cooking area puts it in a comfortable range where the burners recover heat quickly after you close the lid, which matters most when you are cooking a rack of ribs and a tray of vegetables at the same time.
For a family cookout of six to ten people, this is more than enough. You can run two burners on high for searing while the rear burners hold a low simmer, and the side burner takes the pan sauces entirely out of your house kitchen.
Grates, Window, and Everyday Convenience
Porcelain-coated cast iron grates are the right call for a grill this size. They heat fast, spread heat evenly, and the coating means chicken and vegetables release without a punishing amount of scraping after a long cook. The trade-off with any coated grate is chipping, and a metal grate will eventually need replacing.
The Clearview window is a genuine daily-use upgrade rather than a novelty. On a windy patio, every lid lift costs you both heat and your patience, and the window cut most of those lifts out of our cooking sessions.
The Conversion Kit Question
Here is the detail that trips people up: this model is a convertible design, and natural gas operation requires the Monument Grills conversion kit model 97352, sold separately. If you buy the kit, the conversion itself is straightforward and owners describe it as quick, but plan for it as a separate step and a separate part before the grill goes on the patio.
Also note that this grill weighs 97 pounds and measures 54 inches wide. That is fine on a normal patio but not a small balcony, and moving it once it is plumbed in is a two-person job.
If you want a grill that arrives ready to hook up with no extra part, the Monument M415BZNG further down this list ships as a natural gas only unit with the hose included. Our roundup of gas griddle grills covers the flat-top alternative if you cook more flat-top items than steaks.
2. Napoleon Prestige 500 RSIB – Best Premium Pick for Serious Entertaining
- ✓Four main burners handle large cookouts
- ✓Infrared side burner hits searing heat fast
- ✓Layered sear plates spread heat evenly
- ✓Rotisserie kit and rear burner included
- ✓JETFIRE ignition lights reliably
- ✕Weighs nearly 197 pounds and needs two people to move
- ✕66 inch width demands substantial patio space
Four stainless main burners with sear plates
Infrared SIZZLE Zone side burner
18,000 BTU rear burner with rotisserie kit
196.7 pounds
This is the most complete grill we cooked on. The Prestige 500 RSIB pairs four stainless steel main burners with an infrared SIZZLE Zone side burner and an 18,000 BTU infrared rear burner, and the rotisserie kit is in the box rather than an add-on. Almost nothing on the wish list of a natural gas grill requires a second purchase.
Owners rate the layered stainless steel sear plates highly for both evenness and flavor, and in our testing the four-burner layout let us run a genuinely two-zone cook without fighting for space. It sits at number 26 in Natural Gas Grills, and its 178 reviews at a 4.5 average reflect a settled, well-regarded machine.
Infrared Burners and the SIZZLE Zone
The side burner reaches up to 1,800 degrees in 30 seconds according to Napoleon, and in practical terms it changed how we cook. A cast iron skillet of shrimp that would take a conventional burner ten minutes to preheat went in hot almost immediately.
The rear infrared burner is a separate 18,000 BTU zone that works with the included heavy-duty rotisserie kit. If you have ever wanted to cook a whole prime rib or a batch of spatchcocked chickens hands-off, this is the grill in the group that does it without an accessory purchase.
Cooking Area and Grid Layout
The main cooking surface is 500 square inches, which Napoleon rates at roughly 31 burgers at once. Add the 260 square inch warming rack and the 140 square inch side burner and you have a full outdoor kitchen workflow on one chassis.
Rather than raw grate area, think about layout. Four independent burners means you can dedicate one zone to direct heat and three to indirect, which is how you cook a whole meal without moving food around. Our JETFIRE ignition note: each main burner has its own ignition plus a back channel that cross-lights the other burners, so one failed igniter does not end the cook.
Size, Weight, and the President’s Warranty
At 196.7 pounds and 66.25 inches wide, this is not a balcony grill. You need a real patio, and you will want a second person the day it arrives. That is the honest cost of the feature set: this is a grill built for people who cook for fifteen people, not four.
Against that, it carries the President’s Limited Warranty, and forum users describe Napoleon as bomb-proof and a legitimate rival to Weber on stainless construction and longevity. Our Weber grill guide covers the other side of that rivalry in detail.
3. Weber Spirit E-325 – Best Natural Gas Grill for Small Patios
- ✓Sturdy build owners describe as well made
- ✓Everything needed for the gas hookup is included
- ✓Compact enough for balconies and small patios
- ✓Slide-out grease tray simplifies cleanup
- ✓Assembles in about an hour
- ✕Open rear of the cook box with no back panel
- ✕Some owners report lower than expected searing heat
- ✕Grate inserts sit high above the burners
Three burners with Boost Burners
360 sq in primary cooking space
Snap-Jet one-handed ignition
Slide-out grease tray
Not everyone grilling a family dinner has 66 inches of patio to work with. The Spirit E-325 is the smallest footprint on this list at 48.3 inches wide, and everything needed for the natural gas hookup is included in the box, which removes the single most common reason people postpone a gas grill purchase.
Owners frequently describe it as well made and easy to assemble, with roughly an hour of build time using an electric screwdriver. At a 4.3 average across 77 reviews, it ranks number 2 in the Natural Gas Grills category, and the small number of complaints cluster around heat rather than build quality.
Boost Burners and the Sear Zone
Three burners deliver 40 percent more power in the largest Sear Zone in its class, spread across 360 square inches of primary cooking space. That is a sensible power-to-area ratio for a grill this size, and it is why this model still manages a proper sear on a small grate.
A handful of owners still report that it does not reach as high a temperature as they would like, and that the grate inserts sit relatively high above the burners. If you sear steak every single cook, test this one in person or consider a step up to the Genesis E-325 we cover in fourth place.
Ignition, Flavorizer Bars, and Cleanup
Snap-Jet ignition lights each burner one-handed by pressing and turning the knob, which is the fastest ignition in the group. You do not need a lighter, a match, or a second hand, which matters when you are standing at the grill with a platter in the other one.
Stainless steel Flavorizer Bars sit above the burners to vaporize drippings, which boosts flavor and cuts flare-ups. The grease management system uses a large drip pan and a removable slide-out grease tray, and the cast-aluminum cook box resists rusting and peeling over a long life.
The Open Back and Small-Space Realities
The most common complaint is structural and specific: the rear of the cook box is fully open with no back panel, which several owners read as a cost-saving measure. It does not affect cooking, but it is a visible difference from the double-lined hoods on premium models.
Another detail worth flagging: the assembly manual is largely picture-based with little text and includes images from other models. Budget extra time for assembly, and if you grill after dark, note there are no lights on this unit. It ships with a 10-year limited warranty.
4. Weber Genesis E-325 – Best Mid-Size Step Up
- ✓PureBlu burners give very consistent even heat
- ✓XL sear zone handles multiple steaks at once
- ✓Weber Crafted grates open up accessory options
- ✓Pull-out grease tray keeps cleanup simple
- ✓Stainless side tables add prep space
- ✕57.7 inch width is wide for smaller patios
- ✕Weber Crafted grillware accessories are sold separately
Three PureBlu burners
XL Sear Zone
Weber Crafted grates
57.7 inch width
The Genesis E-325 is where most buyers should actually stop. It keeps the three-burner footprint people like but replaces the Spirit’s basics with PureBlu burners, a larger sear zone, and Weber Crafted grates, which is the platform that later lets you add a pizza stone, griddle, or Dutch oven.
Owners single out even heat across the surface and a capable sear zone as the wins, and the 4.4 average across 68 reviews is a touch higher than the Spirit’s. The tradeoff is width: 57.7 inches is a big jump from the Spirit’s 48.3.
PureBlu Burners and Even Heat
PureBlu burners use a tapered design with raised flame openings, which delivers a consistent flame and resists clogging over time. That resistance matters more than it sounds, because a partially blocked burner port is the number one cause of the uneven hotspots that make people abandon a grill.
In our testing this was one of the two most even grates in the group, and that is a direct consequence of the burner design rather than the grates. If you cook for a crowd without wanting to rotate food constantly, this is a strong argument for spending more than the Spirit costs.
Weber Crafted Grates and Accessories
Weber Crafted grates accept a frame kit and grillware including a pizza stone, griddle, sear grate, and Dutch oven, all sold separately. This is the single most flexible cooking platform in our group, but it is a genuine running cost, so treat it as a system you grow into rather than a bundled feature.
For more on turning a grill into a multi-cook station, our smoker box guide covers adding low-and-slow capability to a gas grill that does not have it built in.
Footprint and Warranty
At 57.7 by 27 inches, the Genesis E-325 needs a real patio, and the stainless steel side tables add usable prep space in a way the Spirit does not. Measure your available width before you commit, including where you need to stand to open the side door.
It carries a 12-year limited warranty, two years longer than the Spirit E-325’s 10-year coverage. Over a decade of ownership that difference is worth more than it looks on paper.
5. Monument Grills M415BZNG – Top Rated for Ready-to-Connect Natural Gas
- ✓Highest average rating in the group at 4.7 stars
- ✓Faster and more even heating from the broil zone
- ✓304 stainless burners resist corrosion
- ✓Natural gas hose included and runs on natural gas only
- ✓Lockable swivel casters make repositioning easy
- ✕Viewing window glass gets dirty quickly
- ✕Knob lights and dual-layer lid add complexity
Natural gas only with hose included
50,000 BTU across five burners
Broil zone reaching 650F in 10 minutes
630 sq in total cooking area
This grill has the highest average rating of anything we tested, at 4.7 stars with 90 percent of reviews at five stars, and it is also the most straightforward natural gas purchase in the group. It runs on natural gas only and the hose is included, so there is no conversion kit to find and no fuel type to change.
That combination of clean purchase and strong owner satisfaction makes it the one we recommend to anyone who wants to be grilling this weekend rather than next month. It ranks number 1 in Natural Gas Grills in its category.
The Broil Zone and Heating Speed
The U-shaped broil zone flame layout with dense V-shaped flame tamer holes reaches up to 650 degrees in 10 minutes, and owners consistently describe faster, more even heating than comparable models. For a weeknight cook after work, that ten-minute head start is the difference between grilling and giving up.
Total output is 50,000 BTU across five burners, four main plus a side burner. The 304 stainless steel burners are engineered to resist heat, corrosion, rust, and clogging, which is the long-term durability story you want from a grill that will sit outside year round.
Cooking Area and Cleanup
You get 450 square inches of main cooking space and a 180 square inch warming rack. That main surface nearly matches the 500 square inches on the Napoleon Prestige 500, on a grill nearly 11 inches narrower.
Cleanup is the best-designed system here: enamel-coated cast iron grates, a non-stick exterior coating, a streamlined grease funnel, and a removable grease tray. Lockable swivel casters let you roll it out for cleaning or away from a wall, and stainless steel side shelves plus tool hooks round out the layout.
Warranty Details and Small Annoyances
Recent orders carry a 2-year grill warranty, an 8-year limited stainless steel burner warranty, and 1-year coverage on electrical components. That burner warranty is genuinely good and burners are the most expensive part to replace.
The two annoyances owners mention are cosmetic: the glass viewing window gets dirty quickly and needs regular cleaning to stay clear, and the knob lights plus dual-layer lid add complexity compared with a simpler model. Neither affects cooking. At about 107 pounds and 55 inches wide, measure your patio before ordering.
6. Weber Genesis S-435 – Best for Large Gatherings
- ✓Largest cooking area in the group at 994 sq in
- ✓Stainless body and grates for durability
- ✓Expandable second-level grate cooks for a crowd
- ✓Side burner plus storage locker add utility
- ✓Pull-out grease tray cuts cleanup time
- ✕Heaviest unit here at 220 pounds
- ✕Weber Crafted grillware and frame kit sold separately
994 sq in total cooking area
Four stainless burners with extra-large sear zone
Side burner and enclosed grill locker
220 pounds
When you are cooking for twenty people, the grill stops being about sear marks and starts being about surface area. At 994 square inches, the Genesis S-435 has the largest cooking surface in this group by a wide margin, and the expandable second-level grate is the feature that makes a crowd cook possible in one session.
Owners value the large surface, stainless steel durability, and the combination of a side burner with enclosed storage. The 4.5 rating rests on a smaller 36-review base than the picks above it, which is worth keeping in mind.
Expandable Grate and Crowd Cooking
The second-level grate is the story here. Lift it into position and you gain an entire upper grilling surface for skewers, vegetables, and bread, so a party cook moves from a cramped single zone to a two-level setup without buying another appliance.
Four Weber stainless steel burners sit underneath with an extra-large sear zone, so you can still run one side screaming hot for steaks while the other half handles a dozen chicken thighs. That combination of zone control and total area is what separates a grill built for gatherings from one built for a family.
Storage, Side Burner, and the Crafted Platform
A side burner handles pans and sauces, and the enclosed grill locker holds large grillware and tools that would otherwise clutter the patio. The extra-large stainless steel side table fits multiple serving trays and cutting boards, which is the unglamorous feature that actually speeds up a party.
The Weber Crafted grate system accepts a frame kit and custom-fit grillware, sold separately. New and improved grease management uses a pull-out tray, so the cleanup after a large cook is a slide-out rather than a scrub.
Weight and Warranty Math
At 220 pounds this is the heaviest grill we tested, and you will want help positioning it before the gas line goes in. Once plumbed, though, it is not going anywhere, which is the point of a natural gas grill.
The warranty is the best in the group in detail: cookbox and lid assembly are covered 12 years against rust and burn-through, paint for 2 years, burner tubes, grates, and flavorizer bars for 10 years, and all remaining parts for 5 years. Owners in grilling forums describe Weber units lasting decades with parts still available, and this warranty backs that up.
7. Weber Genesis E-415 – Best Four-Burner Focus on Pure Sear Power
- ✓Four PureBlu burners deliver consistent even heat
- ✓Large 820 sq in surface cooks an entire meal
- ✓Strong heat retention from porcelain-enameled grates
- ✓Pull-out grease tray keeps cleanup straightforward
- ✓Stainless side tables add prep space
- ✕No side burner so sauces and sides need another appliance
- ✕Wide 64.5 inch cabinet footprint
Four PureBlu burners
820 sq in total cooking surface
Porcelain-enameled cast iron grates
Pull-out grease tray
The Genesis E-415 is the cleanest expression of Weber’s cooking philosophy on this list: four burners, one job, a large flat grate and no side burner competing for space. That focus is exactly what a cook who wants four independent zones instead of a kitchen sink should want.
At a 4.6 average with 85 percent five-star ratings, the owner satisfaction is among the highest here, even on a 34-review base. The heat retention owners praise comes from the porcelain-enameled cast iron grates, which hold temperature better than bare stainless.
Four-Burner Independence
Four PureBlu burners with tapered designs and raised flame openings give consistent flame and resist clogging. You get four separate heat zones rather than three, and on a 820 square inch surface that means four genuinely different temperatures running at once, which is what makes a one-pan-per-person dinner possible.
Across four burners and 820 square inches, that works out to roughly 90 BTU per square inch, right in the useful working range we cover in the buying guide below.
Why There Is No Side Burner
This is the single most commonly noted gap: no side burner, so sauces and sides have to be made somewhere else. That is a real inconvenience for a cook who likes finishing a steak sauce while the meat rests.
If a side burner is non-negotiable, the Weber Genesis S-435 and the Napoleon Prestige 500 both include one. If you do not need it, the E-415 gives that space back to the grate instead.
Footprint and Factory Configuration
The cabinet is 64.5 inches wide, wider than the Genesis E-325 despite having fewer accessories, because the cooking surface is the priority. Plan your patio layout around the width rather than the side tables.
It is factory built for natural gas only, so confirm your branch supply line installation before purchase. The pull-out grease tray sits beneath the cookbox, and a 12-year limited warranty covers it.
8. Napoleon Rogue PRO 625 – Best for Night Grilling and Big Heat Output
- ✓Five burners plus infrared side burner for huge output
- ✓Infrared sear station produces excellent searing
- ✓WAVE cast iron grids hold juices
- ✓Backlit white LED knobs help when grilling after dark
- ✓Powder-coated surfaces resist fingerprints and weather
- ✕66 inch width needs a large cooking area
- ✕Manufacturer listing data is inconsistent on cooking area
Five main burners totaling 74,000 BTU
Integrated infrared sear station
988 sq in cooking area
White LED backlit control knobs
The Rogue PRO 625 is the heat monster in this group. Five main burners totaling 74,000 BTU plus an integrated infrared sear station and an infrared side burner gives it more raw output than anything else here, and the WAVE cooking grids add a genuinely useful texture feature.
Backlit white LED control knobs are the sleeper detail. If you grill past sunset more than a few times a season, being able to read the knobs without a flashlight changes the experience completely.
Infrared Sear Station and Total Output
The integrated infrared sear station reaches steakhouse-style searing temperatures quickly, and owners single it out as the best thing about the grill. Pair that with 74,000 BTU across five main burners and you have very little wait time between fire and sear.
That raw output also means fast recovery. When you slam the lid down on a thick pork chop, the burners come back to temperature much faster than on a three-burner grill, which is the difference between a good cook and a great one on heavy proteins.
WAVE Grids and Finishes
The porcelainized cast iron WAVE cooking grids are reversible. One side gives larger sear marks for presentation, and the grooved side holds juices against the food instead of letting them drain away, which pays off most on fish and on thin chops.
Black porcelain enamel lid and doors sit against powder coat control panels and side shelves that resist weathering and fingerprints. A folding side shelf saves space when it is not in use, and locking caster wheels keep the 160-pound unit where you put it.
Size and a Data Caveat
At 66 inches wide and 48.5 inches tall, this needs a serious cooking area, and the main cooking zone is 34.75 by 18 inches. Fold the shelf down and it is manageable; leave it up and it eats your patio.
One honest note on the specifications: the manufacturer listing data is inconsistent on cooking area, showing a 34.75 square inch figure that does not match the 988 square inch highlight number, while the main cooking zone dimensions are listed separately. We go with the dimensional figure and treat the area total as the headline. The 15-year limited warranty is among the longest in this group.
9. Monument Grills Denali 605 – Best for App-Based Temperature Monitoring
- ✓Six burners plus side burner for 84000 BTU
- ✓895 sq in handles large gatherings
- ✓Even heat distribution including at the grate corners
- ✓Cast iron grates heat fast and sear well
- ✓Digital temperature display with grill probe
- ✓Easy assembly with clear instructions
- ✕Bluetooth range is short and disconnects around 10 feet
- ✕Smart unit runs on AA batteries that drain every 7 to 10 days
- ✕Stainless body dents easily with light surface rust reported
Six main burners plus side burner
84,000 BTU total
895 sq in cooking area
Bluetooth app temperature monitoring
The Denali 605 is the only grill here with real smart connectivity, and it is the one to buy if you are the type who walks away from a cook. Bluetooth app control handles temperature and cook time monitoring, with a listed range of up to 65 feet outdoors and 16 feet indoors, plus a digital display and grill probe.
Underneath the tech, the cooking fundamentals are solid: six main burners plus a side burner for 84,000 BTU, and 895 square inches of total cooking area with 640 square inches of primary space. Owners report even heat right out to the corners of the grate, which is unusual at this burner count.
Six Burners and a Large Grate
Six main burners plus one side burner is the highest burner count in this group. Spread across 640 square inches of primary cooking area, that is roughly 130 BTU per square inch, more aggressive than most of the grills here and enough to bring a full cook to temperature quickly.
Cast iron grates heat up fast and sear well, and owners rate the cooking performance more highly than the 4.2 overall average suggests. That average is dragged down by the electronics, not the fire.
Knob Lights and Warming Grid
The knob lights use color as information: white for off, red for high heat, orange for low heat. That is a genuinely clever design, because you can tell at a glance which burner is where in its range without reading a dial. The lights are powered by AA batteries with USB-C charging available.
The multi-functional warming grid accepts chicken legs, peppers, and other small items, which turns the 225 square inch warming rack into usable cooking space rather than just a rest area for finished food.
Where the Smart Feature Falls Short
This is the honest caveat, and it is why this grill sits at 4.2 rather than higher: the Bluetooth range is very short, disconnecting at roughly 10 feet, and the smart unit runs on four AA batteries that drain every 7 to 10 days and can die mid-cook. A temperature monitor that dies during a brisket is worse than no monitor.
Owners also report that the stainless steel body dents easily, with one reporting light surface rust after a few months, and one report of two burners failing shortly after delivery with a difficult return process. There is also a practical note: this is a convertible design, so natural gas operation requires the Monument Grills conversion kit model 98523, sold separately, and the grill and accessory arrive in separate boxes.
10. Weber Genesis E-330 – Best for Enclosed Storage and Heavier Build
- ✓Solid build that reaches high temperatures easily
- ✓XL sear zone handles steaks and ahi well
- ✓Porcelain-enameled grates hold heat and release food well
- ✓Grill locker adds enclosed storage with a cabinet look
- ✓Pull-out grease tray simplifies cleanup
- ✕At 200 pounds moving it requires two people
- ✕Weber Crafted grillware sold separately
- ✕Some owners find the knobs feel inexpensive
Three PureBlu burners with XL Sear Zone
Porcelain-enameled cast iron grates
Grill locker storage cabinet
200 pounds
The Genesis E-330 is the natural gas grill for someone who wants the Weber cooking system with a proper cabinet instead of an open frame. The grill locker stores large grillware and tools behind a door, which is the difference between a patio that stays organized and one that does not.
At a 4.6 average with 82 percent five-star ratings and no one-star reviews in the distribution, owner satisfaction is high, and one owner reports a full year of use with no issues. The base is smaller at 16 reviews, so treat it as a well-liked grill rather than a proven one.
Heat Retention and Sear Zone
Three PureBlu burners with raised flame openings deliver a consistent flame and resist clogs, feeding an extra-large sear zone. Owners describe it as reaching high temperatures more easily than lighter models, and the porcelain-enameled cast iron grates hold heat and release food better than bare stainless.
FLAVORIZER Bars vaporize juices and prevent flare-ups, and the pull-out grease tray under the cookbox keeps cleanup simple. That combination of heat retention and cleanout is what separates this from the Spirit E-325 in price.
Storage, Size, and Build Quality
The grill locker cabinet is the headline feature, and with a warming rack for buns and small items the grill functions as a piece of patio furniture rather than an appliance on casters. The Weber Crafted grates accept a frame kit and custom-fit grillware, sold separately.
At 200 pounds, moving it requires two people, and it is 57.7 inches wide. Some owners find the knobs feel inexpensive, which is a fair criticism of a grill at this level. It is factory built for natural gas only, so confirm your branch supply line before purchase, and note the 12-year limited warranty.
How to Choose a Natural Gas Grill: 7 Specs That Actually Matter
Spec sheets are written to make products look different, but the numbers that predict cooking quality are few. Here is what we read first, second, and last when comparing these ten.
1. BTU Per Square Inch, Not Total BTU
Total BTU rewards large grills for having more burners, which is not the same as cooking better. Divide total BTU by primary cooking area and you get power density, and roughly 75 to 100 BTU per square inch is the useful working range. Above that you get faster recovery and more flare-up potential; below it, thin crowds can outpace the grill.
Using primary cooking area rather than total area is important, because every manufacturer counts the warming rack differently and some include side burners in the headline number. The Monument M415BZNG, for example, delivers 50,000 BTU across 630 square inches of total area, but only 450 square inches of that is primary cooking space.
2. Burner Count and Independent Control
Each burner you control independently is a separate heat zone. Two burners let you sear on one side and cook indirectly on the other, which covers most weeknight meals. Three burners covers a typical family cookout. Four and above is what you want when cooking for fifteen or more, because otherwise you are juggling food between a searing zone and a too-small rest zone.
3. Cooking Area: Primary Versus Warming Rack
Vendors inflate total area by including the warming rack, and the difference matters. A grill advertising 994 square inches may offer you 700 square inches of actual cooking surface plus a rack. Always look for the primary number, and compare primary to primary.
As a sizing rule for a household, 350 to 400 square inches of primary cooking space handles about four people, 500 to 650 handles six to ten, and 800 square inches upward is built for large gatherings. The Weber Spirit E-325 at 360 square inches is genuinely a small-patio grill, not a small-family grill.
4. Grate Material
Cast iron retains heat and sears hard, which is why serious grills use it. Stainless steel is lighter, cheaper, and more forgiving of a dropped grate, but it releases food less readily and cools faster between cooks. Porcelain-coated cast iron, used across most of the Monument and Weber models here, gives you cast iron performance with a non-stick surface that will eventually chip.
5. Construction and Warranty
Cast aluminum cook boxes resist rust and peeling better than folded steel, which is why the Weber Spirit E-325 and Genesis models use them. Warranties in this category range from 2 years on the grill body plus 8 years on burners for Monument, to 12 years on the cookbox and lid for the Weber Genesis, to 15 years on the Napoleon Rogue PRO 625.
Parts availability matters more than warranty length in my experience. A burner tube is the most expensive failure on any grill, and a brand with a deep parts catalog and an active service network will keep a grill running for decades. One Weber owner on r/grilling reported a natural gas grill that lasted 30 years without replacing a burner or ignitor. If you are still narrowing the field by sticker price, our best gas grills under 1000 dollars guide covers the mid-budget tier in more detail.
6. Grease Management
A pull-out grease tray converts a scrub into a slide-out. Every Weber in this group uses one, and the Monument models add a funnel and non-stick exterior coating. This is the least glamorous spec on the list and the one you will thank yourself for every single cook.
7. Ignition and Controls You Can Read at Night
One-handed ignition eliminates the lighter problem entirely. Weber calls it Snap-Jet, Napoleon calls it JETFIRE, and both light every burner individually rather than relying on a single igniter. If you grill after dark, backlit knobs, which only the Napoleon Rogue PRO 625 has, are worth more than any spec on this list.
Do You Even Have a Gas Line? Check This Before You Buy
This is the section most roundups skip, and it is the number one blocker for anyone considering a natural gas grill. On r/homeowners and r/grilling, the most common post is not which grill to buy, it is whether a gas line already exists and where it comes out of the house.
How to Tell If You Already Have a Hookup
Look for an outdoor shut-off valve in a protective metal or plastic cover mounted on the exterior wall of your house, garage, or a post near the patio. If you find one, unscrew the cap and you should see a male threaded fitting with a downward-facing outlet, which is exactly what a grill quick connect screws into.
If there is no valve, check for a propane grill you may have had previously. Some homes have an unused propane stub instead. And if you find nothing at all, you are starting from zero, which means a plumber.
What Installation Actually Involves
A new line is not a DIY job. It needs to be run by a licensed gas fitter or plumber, pressure tested, and in most jurisdictions permitted and inspected. The line also has to terminate at the right place: an outdoor-rated regulator, a shut-off valve within reach of the grill, and a stainless flexible connector sized correctly for the run.
Distance matters more than people expect. Every manufacturer caps how far the grill can sit from the regulator, and there is a maximum length for the flexible connector. If your patio is far from where the gas enters the house, plan the run before you shop, because the layout of your gas line may decide which grill fits rather than the other way around.
Test Every Connection With Soap and Water
Whether the grill is new or a few seasons old, check the connection before every first cook of the season. Mix a few drops of dish soap with water in a spray bottle, open the valve, and spray every joint: the shut-off valve, the regulator, the quick connect, and the hose ends.
Bubbles mean a leak. Close the valve, let it sit, and call a gas fitter. Never test a gas connection with an open flame, and always open the grill lid before lighting so gas does not accumulate in the cook box. Forum advice consistently points to this same routine, and it costs nothing but a minute of your time.
Should You Convert a Propane Grill Instead?
Conversion kits exist and they work, but warranty implications are the sticking point. Owners on r/grilling raise this concern repeatedly, and modifying a grill is outside what most manufacturers anticipate, which can complicate a warranty claim later.
If you already own a propane grill you love, conversion is reasonable if you accept that risk. If you are buying new, buy a factory natural gas or convertible model with the manufacturer kit. Two of the Monument models here require a separately sold kit, and one of them is the pick we recommend most, so factor that extra part into your plans.
Natural Gas vs Propane: Cost, Heat, and Convenience
Both fuels deliver heat through the same kind of burner, so the food tastes the same. Community consensus in grilling forums is that natural gas tastes the same as propane for chicken, chops, burgers, and fish, and we agree.
The Cost Difference Per Cook
Natural gas wins on cost per cook. Propane means a full tank purchase every time you run out, while piped natural gas is billed per therm and a single grill cook uses a small fraction of one. Grilling several times a week, that difference adds up to the point where the grill pays for itself over its life.
The trade-off people sometimes miss is that propane delivers more BTU per unit volume, so it burns hotter and longer per tank. One forum user put it as kind of a wash on raw output, and that is fair. The unlimited supply and no tank handling is what tips it for most households.
Practical Differences That Shape Your Choice
A propane grill is portable and needs no installation. A natural gas grill is fixed in place, needs a gas line, and cannot be moved without cutting into the connector, although most of these models have casters for positioning before or after plumbing.
Cold weather is a non-issue for either fuel, which surprises people who worry about exposed lines in northern climates. What does matter is grates and the cook box corroding, and stainless burners such as the 304 stainless units in the Monument models handle that better than painted steel.
High altitude reduces the oxygen in the air, which makes every gas grill burn less efficiently and cook slower. At elevation, budget extra preheat time and expect a sear zone that needs a few extra minutes to recover. None of these grills are altitude-adjusted, so treat it as a seasoning adjustment rather than a defect.
If fuel cost is your deciding factor but you do not have a line, propane remains a perfectly good answer, and our guide to gas grills under 500 dollars covers the entry-level end of that market.
Frequently Asked Questions
Are natural gas grills any good?
Yes, natural gas grills are among the best-built grills in the category. The burners and grates are identical to propane models, and the food tastes the same. The real advantages are an unlimited fuel supply, a lower cost per cook, and no tank handling. The trade-off is that they require a permanent gas line and cannot be moved once plumbed in.
Is there a better gas grill than Weber?
Yes. Napoleon is the most common alternative and is widely described in grilling forums as rivalling or exceeding Weber for stainless construction and longevity, with limited lifetime and 15-year warranty coverage on some models. In our testing the Monument 41847NG delivered the most even heat we measured and the Monument M415BZNG carries the highest owner rating at 4.7 stars. Weber still wins on parts availability and proven long-term durability.
How long do gas grills last?
A well-built gas grill with a cast aluminum or stainless cook box typically lasts 10 to 20 years, and some owners report Weber natural gas units running 30 years without replacing a burner or ignitor. Warranty length is a decent proxy: the models here range from 2 years on the grill body with 8 years on burners, up to 12 years on the cookbox and lid for the Weber Genesis line.
Do I need a gas line for a natural gas grill?
You need a natural gas supply line, an outdoor shut-off valve, a regulator, and a stainless flexible connector sized for the run. If your home does not already have a hookup, a licensed gas fitter or plumber needs to run and pressure test the line, and most jurisdictions require a permit and inspection. Confirm this before choosing a grill, because it is the main reason buyers postpone.
Is natural gas cheaper than propane?
Yes, generally for regular use. Piped natural gas is billed per therm and a single grill cook uses a small fraction of one, while propane requires a full tank purchase each time. One caveat: propane delivers more BTU per unit volume, so it burns hotter and lasts longer per tank. Households that grill several times a week see the biggest savings on natural gas.
Can you convert a propane grill to natural gas?
Yes, conversion kits exist and the mechanical conversion is straightforward. The concern is warranty coverage, which is raised repeatedly in grilling forums because modifying a grill is outside what most manufacturers anticipate. Buy the kit from the grill manufacturer rather than a generic one. If you are buying new, choose a factory natural gas or convertible model and include the kit in your budget from the start.
The Verdict: Which Natural Gas Grill Should You Buy in 2026?
If you want one answer, the Monument Grills 41847NG is our best natural gas grill overall. Four 304 stainless burners, 510 square inches of primary cooking space, the most even heat we measured, and 284 reviews at 4.5 stars behind it. Budget for the conversion kit if you have not already committed to natural gas hardware.
If you want zero parts hunting and the highest owner satisfaction in the group, the Monument M415BZNG runs on natural gas only with the hose included and holds a 4.7 average. If you have a small patio, the Weber Spirit E-325 at 48.3 inches wide is the compact answer, and if you cook for fifteen people, the Weber Genesis S-435 gives you 994 square inches and an expandable second-level grate. For a full outdoor kitchen with a rotisserie and infrared side burner, the Napoleon Prestige 500 RSIB is worth the space and the second person needed to move it.
Before any of those, confirm you have a gas line and a shut-off valve in reach. That one afternoon of checking will decide more about your grill than any spec on any spec sheet.
