Nexgrill Deluxe 6-Burner Natural Gas Grill
Six main burners, a side burner and an included griddle insert give this cart more simultaneous cooking zones than most models near its observed price position.
- Six stainless main burners
- 775 sq. in. published cooking space
- Side burner and griddle insert
Six main burners plus a side burner support multiple direct and indirect zones.
The included griddle insert adds a flat-top surface without replacing the full grill.
Amazon confirms the natural gas bundle; the manufacturer page supports the six-burner platform but is not fuel-specific.
Monument Grills Mesa M415BZNG Natural Gas Grill
The factory natural gas hose, four main burners, front Broil Zone and 630 square inches of published space provide a capable entry point, with a clear evidence caveat for conflicting page labels.
- 630 sq. in. published total cooking area
- Four main burners plus Broil Zone

| Rank | Natural gas grill | Best for | Format | Published cooking area | Burners and published output | Cooking grates | Special heat feature |
|---|---|---|---|---|---|---|---|
| 1 | Napoleon Prestige 500 RSIB | Best overall | Freestanding cart | 500 sq. in. main; about 900 sq. in. total | 4 main plus infrared side and rear burners; 80,000 BTU family rating | Stainless steel WAVE grids | Infrared side sear and rear rotisserie burners |
| 2 | Napoleon Rogue PRO 625 SIB | Large gatherings | Freestanding cart | 988 sq. in. total; 34.75 x 18 in. main grid | 5 main plus infrared side burner; 74,000 BTU | Porcelain-coated cast iron WAVE grids | Infrared Sizzle Zone side burner |

Published cooking-area labels are not perfectly uniform. Some totals include warming racks. BTU measures fuel input, not heat evenness, grate temperature, or cooking speed.
How the eight grills compare
1. Napoleon Prestige 500 RSIB: Best overall
The Prestige earns the top spot because its cooking system covers more jobs than a standard four-burner cart. Its 500-square-inch main grid handles routine grilling, while the infrared side burner creates a separate searing surface and the rear infrared burner supports rotisserie cooking. The published total cooking space is about 900 square inches.
This is the strongest fit for someone who will use those extra heat zones, not simply admire them. The stainless cart, burners, and WAVE cooking grids also distinguish it from less expensive models with cast-iron grates. The tradeoff is size and complexity: a simpler cart can be easier to live with if weeknight burgers and vegetables make up most of your menu. See the exact natural gas listing and Napoleon’s Prestige platform details.
2. Napoleon Rogue PRO 625 SIB: Best for large gatherings
The Rogue PRO 625 has the largest published cooking area among the freestanding picks: 988 square inches in total, with a 34.75 by 18-inch main grid. Five main burners provide room for several direct and indirect zones, and the infrared side burner keeps high-heat searing off the main grate.
That capacity is useful for cooking multiple foods at once, but it also asks for more patio space than a three- or four-burner cart. The folding shelf and locking casters help with positioning, although a fixed gas hose still defines where the grill can operate. Napoleon lists the exact RP625SIBNK-2 specifications, including natural gas, 74,000 BTU, and a 15-year warranty.
3. Weber Genesis E-330: Best balanced cart
The Genesis E-330 sits between compact carts and the largest gathering-size grills. Its three PureBlu main burners feed a 513-square-inch primary grate, and a dedicated 13,000 BTU sear burner adds concentrated heat. A 128-square-inch warming rack lifts the published total to 641 square inches.
This balance makes the E-330 easier to recommend for everyday backyard cooking than a six-burner station. It still has enough main-grate room for separate heat zones, but it avoids the footprint of the biggest carts. The porcelain-enameled cast-iron grates require a different cleaning routine than stainless grids. Weber’s exact natural gas product page documents the burner inputs and cooking areas.
4. Lion L75623 / L75000: Best built-in
The Lion is the only built-in grill head in our final eight. The natural gas SKU 75623 maps to the 32-inch L75000 platform, which uses 304 16-gauge stainless construction, four cast stainless main burners, solid stainless cooking grids, and an infrared rear burner. Its published cooking surface is 830 square inches.
Those materials and the built-in format suit a permanent outdoor kitchen, but installation is part of the purchase. Cabinet cutout, ventilation, gas supply, shutoff access, and clearances must follow the exact manual and local requirements. A built-in is a poor substitute for a movable cart if the patio layout may change. The exact retailer record links SKU 75623 to the L75000 natural gas platform.
5. Weber Spirit E-425: Best compact cart
The Spirit E-425 puts four burners and a boosted Sear Zone into a cart with a published closed width of 51.8 inches. Weber lists 428 square inches on the main grate and another 105 square inches on the warming rack. That gives it less cooking room than the Genesis, but its four-burner layout provides flexible zoning.
This is the better Weber fit when patio space matters more than maximum grate area. The porcelain-enameled cast-iron grates retain a familiar grilling surface, while the boost burners add searing capability without a separate side station. Confirm the width against the intended location before buying. The exact measurements and output appear on Weber’s Spirit E-425 natural gas page.
6. Nexgrill Deluxe 6-Burner: Best cooking station
Six main burners, a side burner, and an included griddle insert make the Nexgrill the most flexible station-style package in the shortlist. The exact Amazon configuration lists 775 square inches of cooking space and 75,000 BTU total. Nexgrill’s platform page documents 563.55 square inches on the primary surface and porcelain-enameled cast-iron grates.
The many burners are useful when different foods need different heat, but burner count alone does not guarantee more even cooking. It also means more parts and a wider surface to clean. This model makes the most sense for cooks who will use the side burner and griddle insert rather than treating them as occasional extras. Fuel identity comes from the exact natural gas listing.
7. Monument Mesa M415BZNG: Best value
The Mesa M415BZNG combines four main burners, a front Broil Zone, 630 square inches of published total space, and a 10-foot natural gas hose. Its exact Amazon listing and the manufacturer’s specification table support natural gas and 50,000 BTU. The cart offers a useful mix of everyday grilling and a dedicated high-heat section.
There is an evidence caveat. Monument’s current page contains conflicting output labels and an erroneous propane-only label in one part of the interface. We therefore relied on the exact ASIN and the page’s specification table for fuel and output, and scored its evidence below the other finalists. Buyers should verify the model label and manual on delivery. See the M415BZNG product page.
8. Napoleon TravelQ PRO285: Best tabletop
The TravelQ PRO285 is a compact alternative to a full cart. It has a 285-square-inch cooking area and two independently controlled stainless burners with 12,000 BTU total input. The two-burner layout permits basic direct and indirect cooking, even though the surface is much smaller than the freestanding picks.
Its tabletop body fits an outdoor counter or small patio where a cart is impractical, but “portable” does not mean fuel-independent. This version still requires a compatible natural gas connection and should be used only where the manual permits. Napoleon publishes the exact PRO285N-BK specifications.
How we ranked the best natural gas grills
This is a desk-research comparison, not a BTG field test. We started with 20 current Amazon US listings, removed propane-only models, conversion kits, duplicate configurations, and products with unresolved fuel identity, then checked the eight finalists against manufacturer pages, manuals, or stable exact-model retailer records.
The weighted score uses cooking capacity (20%), heat control (20%), burner system (15%), build and durability (15%), format fit (10%), ownership (10%), and evidence confidence (10%). We treated total BTU as fuel input, not a shortcut for performance. Independent grill testing also separates heat evenness, searing, and control from input totals. Prices, stock, and review counts can change, so they are not part of the published table.
Check the gas connection before choosing a grill
A factory natural gas grill is built for a specified household gas supply. It must not be connected to propane. Before ordering, identify the fuel at the intended location, confirm the appliance requirements, and compare the supplied hose and fittings with the connection and shutoff. A licensed gas professional may be appropriate when the connection, pressure, ventilation, or local requirements are unclear.
Do not assume a propane grill can be converted. Only use a conversion method that the manufacturer explicitly approves for the exact model and kit. Built-in heads need extra planning because cabinet ventilation, combustible clearances, access to the shutoff, and service space are part of the installation.
Choose the right size and burner layout
Start with the main cooking grid, not the largest total-area number on the box. Some brands include warming racks in their totals. A 500-square-inch main surface can be more useful than a larger headline number that includes secondary space.
Two or three independently controlled burners are enough to create direct and indirect zones for many meals. More burners help when the grate is wider or several foods need different heat, but they also add controls and cleaning work. An infrared side station is useful for searing without taking over the main grate. A rear burner matters mainly if rotisserie cooking is part of the plan.
Grate materials and routine maintenance
Porcelain-enameled cast iron is common on Weber, Napoleon, Nexgrill, and Monument carts. It offers a substantial cooking surface but should be cleaned without damaging the enamel. Stainless grids avoid a porcelain coating and appear on the Prestige and Lion picks. Neither material eliminates regular cleaning.
Follow the exact manual for cleaning grates, burner ports, grease trays, firebox surfaces, and exterior panels. Keep grease paths clear, inspect the hose and connections as directed, and address damaged parts before using the grill. Turn off the gas supply when the manual calls for it.
Natural gas grill safety basics
Use these grills outdoors only. Follow the model-specific instructions for clearances, connection, leak checks, lighting, shutdown, cleaning, and service. The U.S. Consumer Product Safety Commission advises turning off the gas and not lighting the grill if a leak is detected. Keep ignition sources away until the leak has been addressed.
Never improvise with fuel fittings or place a grill in an enclosed area. If you smell gas, hear gas escaping, or cannot confirm a secure connection, stop and follow the appliance instructions and utility or professional guidance.
Frequently asked questions
Is a natural gas grill cheaper to run than propane?
Operating cost depends on local utility rates, propane prices, and how much fuel the grill uses. Natural gas avoids tank exchanges, but installation or connection work can outweigh fuel savings for some households.
Can I connect a natural gas grill to a propane tank?
No. The fuels use different operating requirements. Use the grill only with the fuel specified on its model label and manual. Do not convert it unless the manufacturer explicitly approves the exact model and conversion kit.
How many burners do I need?
Two independently controlled burners can support basic direct and indirect cooking. Three or four give more zoning on a medium-size grate. Five or six are most useful when the cooking surface is wide or you regularly prepare several foods at different heat levels.
Does a higher BTU rating mean a hotter grill?
Not by itself. BTU is fuel input. Grate temperature and evenness also depend on burner design, firebox shape, distance to the cooking surface, wind, lid use, and heat distribution components.
Which model is best for a built-in outdoor kitchen?
The Lion L75623 / L75000 is the built-in pick in this comparison. Its 32-inch head, stainless construction, solid stainless grids, and rear infrared burner suit a permanent island. The enclosure and gas installation still have to follow the exact manual.
Final verdict
The Napoleon Prestige 500 RSIB is our best overall natural gas grill because its four main burners, infrared side station, rear rotisserie burner, stainless cooking system, and roughly 900 square inches of published total space cover the widest range of backyard cooking. Choose the Rogue PRO 625 when capacity matters most, the Weber Genesis E-330 for a balanced everyday cart, or the Lion L75623 when the project calls for a permanent built-in head.
