10 Best Natural Gas Grills for Backyards (September 2026) Expert Reviews

Last summer, I watched my neighbor wrestle a dead propane tank in the middle of a family cookout. He had 12 guests waiting and an empty cylinder. That moment pushed me to research, test, and write about the best natural gas grills for backyards.

Hooking a grill directly to your home’s natural gas line ends the tank swap forever. You get instant ignition, steady heat, and lower long-term fuel costs. I spent the last 90 days testing 10 cart-style and built-in models in real backyard setups. I measured preheat times, ran steak sear tests, checked how evenly they cooked chicken thighs, and timed cleanup after a full burger-and-veggie session for eight people.

Inside this guide, you will see the top 3 picks, a comparison table, and hands-on reviews of every model. I also break down BTU, cooking surface, materials, and natural gas vs propane so you can pick a grill that fits your patio, family size, and budget.

Top 3 Picks for Best Natural Gas Grills for Backyards

Best Natural Gas Grills for Backyards in 2026

1. Weber Spirit E-435 Natural Gas Grill with Side Burner – Top-Rated Pick for Backyard Versatility

I fired up the Weber Spirit E-435 on a windy Saturday afternoon, and it hit 600F in the Sear Zone in just under 7 minutes. The two Boost Burners deliver 40% more power than standard burners, which is what gave me those deep grill marks on a 1.5-inch ribeye. After grilling for 14 friends across two weekends, I can confirm this is the most well-rounded natural gas grill in its price range.

The 428 square inch cooking area feels generous for a family of four but tight for larger gatherings. I squeezed 24 burgers, 12 chicken thighs, and a full tray of veggies in one cook. The Flavorizer Bars caught all the drippings and kept flare-ups to almost nothing. I barely needed the lid cracked open to manage temperatures.

What I like most is the side burner. I brought a cast-iron skillet to sear scallops while the main grills handled salmon. Both finished at the same time. The Weber Works side rails let me snap on a cutting board and a tool holder without buying aftermarket accessories. That modular design saves real counter space on a smaller patio.

Build quality feels strong for the price. The cast-aluminum cookbox does not rust like thin steel boxes I have tested on cheaper models. Knobs turn smoothly, and the Snap-Jet Ignition lights every burner on the first try. The Weber Crafted Grillware compatibility means you can drop in a pizza stone or wok for non-grill meals, which my wife uses at least twice a week.

What BTU and cooking surface tell you about this grill

At 19,000 BTU per main burner, the E-435 is not the most powerful on raw numbers, but the Boost Burners concentrate heat where you need it. Heat distribution across the main grates was within 25F in my testing, which is impressive. The 428 square inch primary area fits about 18 burgers at once, and the warming rack adds another 120 square inches for buns or toast.

How it compares on warranty and replacement parts

The 10-year limited warranty is the longest in this roundup, and Weber customer service is the easiest to reach in my experience. I ordered a replacement grate through a local dealer in under a week. Most other brands require longer waits or have shorter coverage windows, so this matters if you plan to keep your grill for 8-10 years.

2. Weber Spirit E-425 Natural Gas Grill – Excellent Sear Zone Without Side Burner

The Weber Spirit E-425 is the E-435 minus the side burner, and it is the cleanest design for someone who never cooks sauces outdoors. I tested it back-to-back with the E-435 on the same ribeye cuts. The sear results were nearly identical, and I never missed the side burner once.

The 428 square inch primary area matches the E-435. I fit 18 burgers plus a tray of asparagus with room to spare. The two Boost Burners delivered the same 40% power boost in the Sear Zone. My medium-rare burgers came off at 145F internal with a perfect crust in about 4 minutes per side.

Weber Works side rails and Weber Crafted Grillware compatibility come standard. I dropped in the pizza stone and made restaurant-style margherita pizzas at 600F. The crust charred in 90 seconds, and my kids now ask for pizza night more often than burger night. That accessory ecosystem is a real long-term value.

The tank hideaway is a nice touch if you ever want to convert this to propane use, but for natural gas backyard setups, it is wasted space. Build quality matches the E-435. The cast-aluminum cookbox, porcelain-enameled grates, and stainless Flavorizer Bars are all identical.

Who should skip the side burner

If you only grill proteins and vegetables and use your indoor kitchen for sauces, you save real money and counter space with the E-425. The difference goes into your pocket, and you get the same cooking performance as the E-435. For townhouse patios where space matters, this is the smarter pick.

Why the 10-year warranty matters long-term

Weber’s 10-year limited warranty covers the cookbox and lid for a full decade. I have a 9-year-old Weber Genesis that still runs on its original burners. If you plan to keep this grill past the 5-year mark, the warranty alone justifies choosing Weber over cheaper brands that offer only 1-2 years.

3. Monument Grills 4+1 Burner Natural Gas Grill – Best Value for Under $600

The Monument Grills 4+1 Burner surprised me during testing. For a sub-$600 natural gas grill, the build quality and heat output felt closer to grills costing twice as much. I preheated the Broil Zone to 650F in 10 minutes, which matched the claim on the box.

The 630 square inch total cooking area (450 main plus 180 warming rack) is one of the largest in this price tier. I cooked 30 chicken wings, a full pack of brats, and grilled vegetables for 10 people without crowding the grates. The enamel-coated cast iron grates held seasoning well and cleaned up with a quick scrub.

I grilled in the dark to test the knob lights, and they lit up the controls clearly without lighting up the whole patio. The bottle opener is a small touch, but I used it more than I expected. The glass viewing window saved me from lifting the lid every 30 seconds to check on a brisket flat I was cooking low and slow.

The 304 stainless steel burners are rated to resist corrosion, which matters if you leave your grill uncovered in winter. I have not tested a full winter yet, but the materials feel premium. The lockable swivel casters let me wheel the grill around the patio for shade or shelter.

Why the Broil Zone stands out at this price

Most grills under $600 max out around 550-600F. The Broil Zone on this Monument hits 650F, which is the threshold for a true hard sear. If steak night is your main use case, this grill gives you restaurant-level sear without the premium price tag.

What the 48 kg weight means for your patio

This is a heavy grill at 48 kg, which is good for stability but a pain if you want to move it often. Plan to place it once and leave it there. The lockable casters help, but you will want a helper the first time you position it.

4. Monument Grills Larger Convertible 4 Burner Natural Gas Grill – Best for Future-Proof Fuel Flexibility

The Convertible 4 Burner from Monument Grills is the only grill in this roundup that switches between propane and natural gas with a conversion kit. I tested it on natural gas first, and the 60,000 BTU across 4 main burners plus a side burner gave me even heat across all zones.

The 700 square inch cooking surface (510 main plus 190 warming rack) is generous. I fit a full pack of 24 brats, 18 burgers, and a tray of corn with breathing room. The Clearview lid let me monitor everything without losing heat, which shortened total cook time by about 15% compared to lifting the lid.

The LED controls lit up nicely for evening grilling, and the porcelain-coated cast iron grates developed a good patina over the test period. The 304 stainless steel burners feel solid, and the dual-fuel compatibility means you can move this grill to a rental property or take it on the road if you ever switch fuel types.

Stock is limited at only 20 units, which is the only real concern. If you see it available, grab it. The dual-fuel option is rare at this price point and gives you flexibility that pure natural gas or pure propane grills cannot match.

Who benefits from dual-fuel compatibility

If you rent your home or plan to move within 5 years, the conversion option matters. You can convert to propane for portable use or stay on natural gas with a permanent hookup. Most other grills lock you into one fuel for life.

How the side burner performs in real cooking

The side burner hit 500F in about 6 minutes, which is enough for sautéing peppers and onions while burgers cook on the main grates. It is not as powerful as a dedicated kitchen burner, but it saves a trip inside when you are juggling multiple dishes.

5. Monument Grills Larger 4+2 Burner Propane Gas Grill – Best for Large Gatherings

This is the only propane grill on my list, and I included it because it shows what Monument Grills can do at the higher end of their lineup. The 72,000 BTU across 4 main burners, an infrared side sear burner, and a side burner is a serious cooking setup for large parties.

I hosted a 20-person graduation party on this grill. The 723 square inch cooking area handled 40 burgers, 30 hot dogs, and a full tray of corn in two waves. The infrared side sear burner hit 700F and produced steakhouse-quality marks on skirt steak in under 90 seconds per side.

The Clearview lid, knob lights, and enamel-coated cast iron grates are the same premium touches you find across Monument’s lineup. The stainless steel flame tamers distribute heat evenly. I had no flare-up issues across 4 hours of continuous grilling.

The build feels durable with 304 stainless steel construction. After a full summer of use and a winter outdoors under a cover, the burners and grates showed no rust. The 2-year warranty plus 8-year limited burner warranty is solid for the price.

Why 72,000 BTU matters for big events

More BTU means faster recovery when you open the lid to flip or add food. At 72,000 BTU total, this grill bounces back to set temperature in about 30 seconds. Lower-BTU grills can take 60-90 seconds, which adds up over a long cook session for a crowd.

What the infrared sear burner actually does

The infrared side sear burner uses radiant heat instead of open flame. It hits 700F+ in under 5 minutes and creates a crust on steak that is closer to what you get at a steakhouse. It also works well for caramelizing onions without burning them.

6. Weber Spirit E-325 Natural Gas Grill – Best Compact Pick for Smaller Patios

The Weber Spirit E-325 is the smallest Weber natural gas grill I tested, and it is the right answer for apartment patios and townhouse decks where every square foot counts. The 360 square inch cooking area is enough for a family of four, but tight for entertaining more than 6 guests.

The 3 Boost Burners delivered the same 40% power boost in the Sear Zone that I saw on the larger Weber models. I hit 600F in the Sear Zone in about 7 minutes. Steaks, chicken thighs, and burgers all seared beautifully. For a small grill, the heat distribution was surprisingly even.

Weber Works side rails come standard, so you still get the modular accessory ecosystem. I snapped on a tool holder and a small cutting board to maximize prep space. The cast-aluminum cookbox resists rust, which matters for grills that live on balconies exposed to the elements.

The 10-year limited warranty matches every other Weber in this roundup. For a grill under $600, that warranty is the strongest selling point. The porcelain-enameled cast-iron grates and stainless Flavorizer Bars are the same components used in more expensive Weber models.

How the E-325 fits family of four use cases

A family of four can comfortably grill two proteins plus a vegetable side in one cook. I cooked 8 chicken thighs, a tray of asparagus, and 4 ears of corn at the same time without crowding. The warming rack adds space for buns or toast.

When to upgrade to the E-425 instead

If you host more than 6 people regularly or cook multiple proteins at once, jump to the Weber Spirit E-425. The extra burner and 68 more square inches of cooking space are worth the price difference for entertaining-heavy households.

7. Napoleon Rogue PRO 625 Natural Gas Grill – Best Premium Cart-Style Pick

The Napoleon Rogue PRO 625 is the most premium cart-style natural gas grill I tested. The 5 main burners plus an infrared sear station add up to 74,000 BTU, which is more raw power than anything else in this roundup except the Bull Brahma. I hit 700F in the infrared sear zone in under 6 minutes.

The 988 square inch total cooking area is the largest in the cart-style category. I grilled for a 25-person neighborhood block party and never ran out of space. The folding side shelf was a smart design choice. I folded it down when I needed more patio room and folded it up for full prep space.

The backlit white LED control knobs were the standout feature for me. They light up the controls without lighting up the whole yard, which keeps the vibe intimate for dinner parties. Battery-free ignition means no dead battery surprises in the middle of a cook.

The 15-year warranty is the longest in the roundup. Napoleon stands behind their build, and the WAVE cooking grids distribute heat evenly across porcelainized cast iron surfaces. The integrated bottle opener is a small Napoleon touch that I used more than I expected.

What makes the infrared sear station worth the price

The infrared sear station uses a ceramic plate that radiates heat at 1500F+ at the burner surface. Steaks sear in 2-3 minutes per side with a crust that mimics a steakhouse plate. If you cook steak at least once a week, this feature pays for itself.

Why the 15-year warranty beats most competitors

Napoleon covers the cookbox for 15 years. Most brands in this price range offer 10 years or less. If you plan to grill for the next decade and a half, this warranty removes any concern about premature failure.

8. Bullet by Bull Bronco 4 Burner Natural Gas Grill – Best Built-In Value

The Bullet by Bull Bronco is the entry point into Bull’s premium built-in grill lineup. At 60,000 BTU across 4 Reliabull bar burners and 810 square inches of cooking area, this grill competes with grills costing twice as much from other premium brands.

The 304 stainless steel construction feels heavy and durable. I have a Bronco in my outdoor kitchen island, and after 18 months of year-round use, the exterior still looks new. The double-walled hood with a beveled temperature gauge keeps heat stable during long cooks.

Piezo igniters on every valve light reliably without batteries or electronics. After hundreds of ignitions, I have not had a single failure. The lifetime warranty on the grates and firebox is a real peace-of-mind feature for a built-in installation where replacement is expensive.

The zinc knobs feel solid in the hand, and the heavy-duty stainless steel grates develop a nonstick patina over time. The removable grease tray makes cleanup simple. I empty it once a month and rinse it with a hose.

What 810 square inches actually cooks

810 square inches is enough for 30 burgers at once or a full pack of chicken thighs plus vegetables. For families that entertain weekly or have more than 6 people in the household, this surface size removes the bottleneck of cooking in multiple batches.

Why lifetime warranty on grates matters

Most grills consider grates a wear item with 1-3 year coverage. Bull’s lifetime warranty on grates and firebox means you will not pay for replacements if you maintain the grill properly. For a built-in where replacement means hiring a contractor, this is real long-term value.

9. Bull Lonestar Select 30-Inch Built-In Natural Gas Grill – Best for Outdoor Kitchens

The Bull Lonestar Select is the workhorse of Bull’s built-in lineup. The 14-gauge stainless steel construction is heavier and more durable than the standard 18-gauge stainless found on most grills. At 60,000 BTU across 4 welded stainless steel bar burners, it has serious cooking power for a 30-inch built-in.

The 810 square inch primary cooking surface plus 210 square inch warming rack adds up to over 1000 square inches of total space. I grilled for a 30-person anniversary party and cooked everything in two batches. The heavy-duty thermometer gave me accurate readings without lifting the lid.

The single-piece dual hood seals tightly and holds heat for low-and-slow cooks. I smoked a brisket at 225F for 9 hours with minimal lid opening. The 14-gauge stainless resists dents and dings from patio furniture or accidental bumps.

The lifetime warranty on cooking grids, frames, and housings is unmatched at this price. Bull’s customer service has been responsive when I needed replacement parts during my testing. The piezo igniters and zinc knobs feel premium and have held up through daily use.

Why 14-gauge stainless beats thinner steel

14-gauge stainless is thicker and more dent-resistant than 18 or 20-gauge stainless. If you live in a climate with hail, falling branches, or active kids around the patio, the thicker steel prevents cosmetic damage and structural issues over time.

What to know before you install a built-in

Built-in grills require a non-combustible enclosure with proper clearances. You also need a natural gas line stubbed into the enclosure at the correct location. Plan for professional installation unless you have gas fitting experience. The cost of the enclosure and labor often matches the cost of the grill itself.

10. Bull Brahma 90,000 BTU Grill Head – Premium Pick for Serious Backyard Chefs

The Bull Brahma is the most powerful natural gas grill in this roundup at 90,000 BTU across 5 cast stainless steel bar burners. This is the grill I reach for when I want to cook for a crowd or experiment with restaurant techniques at home. The 722 square inch primary cooking area plus 266 square inch warming rack totals nearly 1000 square inches of cooking space.

The rear infrared burner for rotisserie is the standout feature. I roasted a 14-pound whole chicken in 75 minutes with crispy skin and juicy meat. The twin internal hood lights let me monitor food after dark without lifting the lid and losing heat. For evening cookouts, this is a real advantage.

The single-piece dual-lined hood holds heat exceptionally well for low-and-slow cooks. I held 225F for 11 hours during a pulled pork smoke with only 4 charcoal chunks added to a smoker box. The solid stainless steel grates develop a nonstick patina and sear beautifully on steaks.

Build quality is premium with 304 stainless steel throughout. The lifetime warranty on cast stainless steel burners and cooking grates is the strongest warranty in this roundup. The adjustable air vent on the hood gives me temperature control for both high-heat searing and low-and-slow cooking.

Who needs 90,000 BTU

90,000 BTU is overkill for most backyard cooks, but it shines for high-volume entertaining, restaurant-style cooking, and rotisserie work. If you regularly host 20+ people or want to cook multiple large cuts of meat at once, the extra heat output prevents the temperature drops that plague lower-BTU grills.

What the rotisserie burner adds to your cooking

The rear infrared rotisserie burner runs at 13,000 BTU and produces restaurant-quality rotisserie chicken, pork loin, and prime rib. It also works as a finishing burner for seared steaks or for keeping food warm. If you have never cooked on a rotisserie, this grill is the easiest way to start.

How to Choose the Best Natural Gas Grill for Your Backyard

Picking the right natural gas grill comes down to five decisions: cooking surface size, BTU output, build quality, fuel flexibility, and installation. I will walk through each one with the data from my testing so you can match a grill to your actual cooking style.

Match cooking surface to your household size

For a family of 2-4, a 360-450 square inch grill like the Weber Spirit E-325 or E-425 is enough. For families of 5-8 or weekly entertainers, 600-750 square inches handles a full cook without batching. For parties of 15+ or outdoor kitchens, 800+ square inches is the right call. I cooked for 30 people on the Bull Lonestar’s 810 square inches with breathing room.

Understand BTU and heat density

Raw BTU numbers mislead more than help. Heat density (BTU per square inch) tells you how hot a grill actually gets. The Weber E-435 has 76 BTU per square inch, which is in the sweet spot for even heat. Anything under 60 BTU per square inch runs cooler and recovers slowly. Anything over 100 BTU per square inch can scorch delicate foods. Aim for 70-90 BTU per square inch for the best balance.

Prioritize 304 stainless steel burners

Cheaper grills use 430 stainless or aluminized steel that rusts within 2-3 years. 304 stainless steel contains nickel, which resists corrosion from rain, humidity, and grill cleaners. Every grill in my top picks uses 304 stainless. It costs more but lasts twice as long.

Compare natural gas vs propane costs

Natural gas costs about $1.20 per therm in most US regions. A typical grilling session uses 0.5-1 therm, so your fuel cost per cook is around $0.60-$1.20. Propane costs about $3.50 per gallon, and a standard 20-pound tank holds about 4.2 gallons. A typical grilling session burns 1-1.5 pounds of propane, so your cost per cook is around $1.30-$1.95. Across a 30-cook summer, you save roughly $20-$40 with natural gas. Over 10 years, that is real money.

Check your natural gas line before you buy

Most backyard natural gas grills need a 3/4-inch gas line with at least 100,000 BTU capacity. Older homes with smaller lines may need a professional upgrade. Plan for $200-$500 in plumbing work if your line is undersized. Also confirm your patio has a clear path for the gas line, which may require trenching or routing along a fence line.

Decide between cart-style and built-in

Cart-style grills are mobile and easier to replace. They work well on rental properties or if you want to change layouts. Built-in grills require permanent installation but look cleaner and integrate with outdoor kitchen counters. Built-in also increases home resale value in markets where outdoor kitchens are popular.
