$563.99$641.64as of Jul 15, 2:45 PMHow To Choose The Best Barbecue Gas Grill
Picking the right gas grill is not about the biggest number on the box. You need to match the cooking area to how many people you feed, the BTU output to how fast you want to sear, and the build quality to how many seasons you expect it to survive. Here is what actually matters.
Cooking Area and Burner Count
A 310-square-inch surface (like the Charbroil Performance 2-Burner) handles about 17 burgers at a time — fine for a couple or a small family. Jump to 525 or 602 square inches (Monument Grills Mesa II or Royal Gourmet GA5401T) and you can cook for a crowd or keep space for indirect grilling. More burners give you finer heat zones across the grates, so you can sear on one side and cook low on the other.
Heat Output and Infrared Technology
BTUs (British Thermal Units — the standard unit for measuring heat energy) tell you the raw power, but how that heat reaches your food matters more. Infrared cooking systems, like the one on the Charbroil Pro Series, use a ceramic or metal emitter to radiate steady, flare-up-resistant heat rather than relying on open flames. Buyers report that infrared grills eliminate grease fires, which is a real advantage when cooking fatty burgers or marinated chicken.
Grate Material and Durability
Porcelain-enameled cast iron grates (found on the Weber Spirit E-325 and Captiva Designs 4-Burner) combine the heat retention of cast iron with a non-stick, rust-resistant coating. Stainless steel grates (like the Weber Genesis S-435) resist corrosion better over time but do not hold heat as evenly. If you grill year-round, porcelain-coated cast iron usually gives you the best mix of searing and easy cleanup.

In‑Depth Reviews
1. Charbroil Performance Series 2-Burner Gas Grill Cabinet, Stainless Steel
Our pick — 4.5★ from 13,000+ verified ratings; the strongest balance of quality and price.
$299.99as of Jul 15, 2:45 PMThe best-selling 2-burner in the country fits 17 burgers on 310 square inches and lights with one button every time.
The advanced FlavorMax cooking system produces more consistent results, stress-free cooking, and juicier foods by managing heat and vaporizing drippings. Porcelain-coated grates retain heat for even cooking and impressive grill marks while resisting rust. An 85-square-inch swing-away warming rack lets you cook with indirect heat or keep food warm, and it swings away when you need the full 310-square-inch grate. The electronic ignition fires up instantly — turn the knob, press the button, and you are grilling.
Buyers consistently call this a great little grill for couples or small families. One customer observed the infrared grill eliminates grease fires, which makes it a strong pick for fatty burgers. The folding side shelf and two 7-inch heavy-duty caster wheels make storage and repositioning easy. Assembly is straightforward — one buyer finished in about 90 minutes with the hardware packed cleverly. The closed storage cabinet hides your propane tank and tools. The grill is 25 inches deep, and multiple owners point out that most standard grill covers are 22 inches deep, so you will need a cover that fits.
What Keeps It a Top Seller
- Electronic ignition lights every time with one button press
- Infrared technology virtually eliminates flare-ups
- FlavorMax system delivers juicier, more consistent results
- Compact footprint with cabinet storage fits small patios
Two Practical Shortfalls
- 25-inch depth means most standard 22-inch grill covers will not fit
- 2 burners limit heat zone control compared to 3- or 4-burner models
A strong fit for: Couples or small families who want the #1 gas grill brand in the USA, a reliable igniter, and flare-up-free cooking without spending much.
Not right if: You need to cook for more than 4 people at once or want separate heat zones for different foods.
2. Weber Spirit E-325 Liquid Propane Gas Grill
$499.00as of Jul 15, 2:45 PMThe Weber that sears ribeyes to 130°F in eight minutes flat — on a 360-square-inch stage.
You get two Boost Burners (the maker says they unleash 40% more power) that create the largest Sear Zone in its class, so multiple steaks can get a crust at once without crowding. The porcelain-enameled cast-iron grates hold heat evenly and wipe clean easily, while the stainless steel Flavorizer Bars (angled bars that catch dripping juices and vaporize them back into the food for smoky flavor) funnel grease away from the burners to prevent flare-ups.
Owners mention the assembly takes about an hour with just a Philips screwdriver, and one reviewer noted that the 10-year limited warranty on major parts makes the price feel like a solid investment. The catch is the plastic wheels — they are not as sturdy as the older Weber models — and the open back leaves a gap where small critters can sneak into the cabinet.
Unlike the Charbroil Performance 2-Burner’s 310-square-inch surface, the Spirit E-325 gives you 360 square inches plus a warming rack, which still keeps it compact for a couple but adds that serious sear capability. The Snap-Jet Ignition (push and turn the knob to light each burner individually with one hand) makes startup easy even when your other hand is full of tongs.
What Makes It the Top Pick
- Boost Burners produce intense heat for steakhouse-level searing
- Porcelain-enameled cast-iron grates resist rust and retain heat evenly
- Slide-out grease tray makes cleanup fast — no scrubbing
- 10-year warranty on burners and cook box covers your investment
Two Real Trade-offs
- Plastic wheels feel less durable than older Weber models
- Open back in the cabinet lets leaves and critters in
Your best bet if: You want a compact, fast-heating grill with a powerful Sear Zone that will still be cooking well a decade from now.
Look elsewhere if: You need enough surface area to feed more than six people regularly or want lockable heavy-duty casters.
3. Charbroil Pro Series with Amplifire Infrared Technology 4-Burner Propane Gas Grill
$563.99$641.64as of Jul 15, 2:45 PMOne grill that switches between gas, griddle, and charcoal in under 90 seconds — with 802.9 square inches to feed a block party.
The Amplifire infrared cooking system grills juicier food, eliminates guesswork, and prevents flare-ups — customers note it keeps food moist with no grease fires, which is a direct advantage over open-flame grills when cooking fatty cuts. You get 535 square inches of primary cooking space plus a 155-square-inch warming rack, enough to fit 25 burgers, 18 chicken breasts, or 12 steaks at a time. The 45,000 BTU rating powers four burners, and the maker specifies that BTU is a measure of energy used, not a guarantee of higher temperature — it means the grill burns less fuel to cook your food.
The modular system is the headline here. Swap the porcelain-coated cast-iron grates for a heavy-duty 328-square-inch cold rolled steel griddle top (the rear slot deposits excess grease, and legs let it hang from the griddle rail when not in use), or buy the patented Gas2Coal charcoal tray (sold separately) and drop it over the burners for charcoal flavor. Two heavy-duty 8-inch wheels plus two locking casters make rolling this 802.9-square-inch unit manageable. Assembly takes hours and the printed instructions are poor, but the 10-year burner warranty takes the sting out of the setup pain.
Why This Versatility Wins
- Three cooking modes (gas, griddle, charcoal) in one frame
- Infrared system eliminates flare-ups almost entirely
- Massive cooking area fits 12 steaks at once
- Two 8-inch wheels roll smoothly over patio cracks
The Real Frustrations
- Assembly is an hours-long project with hard-to-follow diagrams
- Charcoal tray heats up slowly compared to gas mode
Reach for this if: You want the flexibility to gas-grill, griddle breakfast, or charcoal-sear from the same unit without buying three separate grills.
skip it if: You do not want to spend hours assembling it or you only need a simple gas grill with no extras.
4. Weber Genesis S-435 Liquid Propane Gas Grill
$1,699.00as of Jul 15, 2:45 PMA 220-pound stainless steel fortress with four burners, a side burner, and a second-level grate for serious entertaining.
The four high-performance burners (Weber’s proprietary design) produce an even, efficient flame, and the extra-large Sear Zone means you can sear multiple steaks at once without dropping the temperature. The side burner handles sauces or sautéed veggies, and the extra-large side table fits several serving trays — everything stays within arm’s reach. The new grease management system pulls out and scrapes clean in one motion.
Reviewers point out the assembly is an all-day project with poorly illustrated instructions and unmarked screw bags, but the build quality is impeccable once it is together. The stainless steel cooking grates resist corrosion and stay sturdy, and the expandable top cooking grate creates a large second level for indirect cooking. At 220 pounds, this is not a grill you shuffle around — but the 35.5 x 30.75 x 31-inch footprint is surprisingly compact for a four-burner unit. One buyer mentioned the built-in fuel gauge is not accurate and recommends a digital scale for precise propane tracking.
What improve It Above the Rest
- Four burners plus a side burner deliver real cooktop flexibility
- Stainless steel grates resist rust and hold up for years
- Slide-out grease tray makes post-cook cleanup almost zero effort
- Expandable top grate adds a full cooking level for indirect heat
What to Expect Before You Buy
- Assembly takes a full day and requires patience with vague instructions
- Propane fuel gauge is unreliable — plan for a separate digital scale
- Weighs 220 pounds, so permanent placement is best
Your pick when: Build quality, four-burner cooking, and a premium stainless finish matter more than quick assembly or a low price tag.
Look elsewhere if: You need something that assembles in under an hour or you regularly move your grill between locations.
5. Monument Grills 4 Burner Propane Gas Grill Mesa II 410FBZ
$299.00as of Jul 15, 2:45 PMHits 500°F in 5 minutes, assembles in 30, and leaves money in your pocket for a good steak.
The Advanced Broil Zone sears fast and gives you precise heat control across four burners, while the corrosion-resistant 304 stainless steel burners deliver consistent heat and longevity. The enameled cast-iron cooking grates hold temperature well and produce restaurant-quality grill marks. With 525 square inches of total grilling area (primary plus a flip-up warming rack), two foldable side shelves, and a stainless steel side table, there is plenty of room for prep and cooking.
Buyers highlight the quick assembly — one person reported it took about 45 minutes with only a Phillips screwdriver — and the even heat distribution makes food cook perfectly on the first try. One owner reported the grease catching system is awkward and fills with water when it rains, so you will want to store this grill under a cover. The funnel-style grease management system and removable 430 stainless steel drip pan do make daily cleanup simple when the weather cooperates. Compared to the Royal Gourmet GA5401T’s 602 square inches, the Monument is slightly smaller but heats faster and costs less.
Why It Stands Out
- Heats to 500°F in about 5 minutes — faster than many pricier grills
- 304 stainless steel burners resist corrosion and last
- Assembly is genuinely quick, usually under an hour
- Four burners and a Broil Zone give you real heat zone control
The One Catch
- Grease management system is poorly designed — collects rainwater if left uncovered
Ideal for: Someone who wants the heat and capacity of a four-burner grill without spending premium money or hours on assembly.
Consider passing if: You grill in exposed weather frequently and cannot commit to storing the grill under a cover each time.
6. Captiva Designs 4-Burner Propane Gas BBQ Grill with Side Burner
$334.99$399.99as of Jul 15, 2:45 PM42,000 BTUs of even heat across 545 square inches, backed by a side burner and a deep storage cabinet.
The porcelain-enameled cast-iron grates (the brand upgraded them to combine cast iron’s heat retention with a non-stick, rust-resistant enamel coating) distribute heat evenly across four stainless steel burners and enameled flame tamers. The 400-square-inch primary cooking area plus 145-square-inch warm rack gives you room to cook different foods at different temperatures simultaneously. The full-size pullout oil drip tray collects grease during cooking and slides out for easy pouring and cleaning.
Shoppers say that the grill heats quickly and evenly, with one reviewer mentioning the side burner is useful for sauces or even brewing. The 22 x 51 x 41.5-inch footprint with a large bottom storage cabinet handles your propane tank, utensils, and seasonings in one organized spot. You do need two people for assembly, and some units arrive with dents and scratches — but the seller responds within 24 hours, and multiple customers noted the rebate made the cosmetic issues acceptable. Paint flaking in the cook-box after several uses is a concern raised by one long-term owner.
What Makes It a Strong Contender
- Porcelain-enameled cast-iron grates sear well and are easy to clean
- Pullout drip tray makes grease management simple
- Large storage cabinet keeps tools and tank organized
- Side burner adds real cooking flexibility for sauces or sides
Common Buyer Frustrations
- Some units arrive with dents, scratches, or paint flaking
- Assembly takes 1.5+ hours and needs two people
Pick this if: You want a powerful four-burner with a side burner, easy grease cleanup, and a generous storage cabinet without paying premium-brand money.
Think twice if: A flawless out-of-the-box finish is important to you — cosmetic damage in shipping is a recurring theme in reviews.
7. Royal Gourmet GA5401T 5-Burner BBQ Liquid Propane Gas Grill with Side Burner
$275.51as of Jul 15, 2:45 PM602 square inches of grilling space across five burners — a 1.9x surface advantage over the Charbroil Performance 2-Burner’s 310 square inches.
The primary grilling surface is 476 square inches, plus a 126-square-inch warming rack, giving you room for a full party spread. Four 10,000 BTU main burners handle core cooking, a 12,000 BTU sear burner delivers high heat for steakhouse-style searing, and a 9,000 BTU side burner adds flexibility for sides or sauces. The double-layer stainless steel lid retains heat and helps infuse food with rich grilled flavor. Buyers report that the 4 burners and side burner work great, though several note that the sear burner is the coldest area on the grill — it should be the hottest, so treat that label with some skepticism.
Assembly is the main headache here. The instructions are mostly small-print drawings, and even handy owners mention it taking 4 hours. The warming rack paint may burn off during the first seasoning and create a gooey mess — multiple reviewers mention this, so plan to let the grill burn on high for a few hours before any food touches the grates. Once set up, it heats to 750°F in about 10 minutes, and the knobs feel smooth and well-made.
The Strengths That Earn Its Spot
- Massive 602 sq in total cooking area — one of the largest at this price tier
- 61,000 BTU total output gets hot fast and stays hot
- Side burner adds real utility for sauces and sides
- Double-layer lid retains heat well for even cooking
The Pain Points Customers note
- Assembly is a long process with very small, hard-to-read instructions
- Sear burner runs cooler than the main burners, opposite of what you expect
- Warming rack paint burns off on first use — needs pre-burn treatment
Grab this for: Large gatherings where you need 602 square inches of cooking surface and five burners to juggle different temps — all at a mid-range price.
Pass if: You do not want to spend several hours on assembly or you expect a dedicated high-heat sear burner to actually get hotter than the rest.
8. Propane Gas Grill 4 Burner Griddle & Grill Combo (ideamaxx)
$299.00as of Jul 15, 2:45 PMTwo cooktops in one frame — ridged grates for sear marks and a flat griddle for pancakes, all running on 49,000 BTUs.
The reversible porcelain-enameled cast iron surface gives you two cooking options: the ridged grill side produces sear marks on steaks, burgers, and chops, while the flat griddle side handles eggs, bacon, fish, or veggies that would otherwise fall through grates. Four high-output stainless steel main burners plus a dedicated side burner let you simmer sauces or boil corn simultaneously. The 440-square-inch main cooking area plus a warming rack fits up to 20 burgers and serves 8 to 10 adults.
Reviewers point out the grill is well-made and fortified for strength, with one reviewer expecting longevity closer to 20 years than 5. Another owner noted the griddle is awesome but some buyers warn the burners feel weak and the materials are cheap. The porcelain-enamel coating on the cast iron grates creates a non-stick, rust-resistant surface that brushes clean easily. Assembly takes about an hour alone, and the 19.1 x 48.1 x 45.6-inch cabinet frame holds everything stable.
The Versatility You Get
- Reversible cast iron surface gives you a grill and a griddle in one unit
- Side burner adds heat for sauces or sides while grilling
- Porcelain-enamel coating resists rust and is easy to clean
Mixed Signals From Buyers
- Some shoppers say weak burners and cheap material quality
- Warming rack paint may burn off on first use — needs seasoning
Best suited for: A cook who wants one machine that flips between grilling steaks and griddling breakfast without buying a separate flat top.
Think twice if: Consistent high heat across all burners is non-negotiable for you — there are mixed reports on burner strength.
9. Nexgrill Deluxe 2-Burner Gas Grill with 401 SQ In Grate
$299.00as of Jul 15, 2:45 PM401 square inches of cooking space, 28,000 BTUs, and two foldable side tables — all in a 2-burner frame that fits tight balconies.
The porcelain-coated cast iron grates offer even heat distribution, non-stick performance, and rust resistance. Two high-powered burners produce 28,000 BTUs for fast, efficient heating, and the one-button electric ignition provides a stronger spark that works even in windy conditions — no matches needed. A lid-mounted thermometer lets you monitor cooking temperatures without lifting the lid, and accessory hooks keep tongs and brushes within reach.
Buyers report the assembly takes about an hour with basic tools, and the grill lights instantly with no cold spots. The two side tables fold down for compact storage. A stable cabinet with four smooth-rolling casters makes moving it around a balcony or small patio easy. Some customers note that only the handles are true stainless steel — other parts may rust over time — and one owner expects a 3-year lifespan due to cheap burners. The stainless steel control panel is rust-resistant and easy to clean, and the 22.44 x 42.52 x 46.46-inch footprint is among the most space-efficient in this list.
What Fits a Small Space
- 401 sq in surface fits 8-10 burgers in a very compact frame
- Foldable side tables make storage easy when not in use
- One-button ignition works reliably in windy conditions
- Four smooth-rolling casters move easily on hard surfaces
Trade-offs to Know
- Some parts (screws, non-handle metal) may rust over time
- Burner quality is mid-tier — some owners mention a 3-year lifespan
- Missing hardware in the box is a recurring issue in reviews
Choose this for: A compact balcony or small patio where 401 square inches of cooking area fits better than a full-size 4-burner, with foldable tables to save space.
Pass if: Long-term durability beyond 3-4 seasons is a priority — or you prefer stainless steel construction throughout, not just on the control panel and handles.
Understanding the Specs
BTU (British Thermal Unit) — What It Really Tells You
BTU is the standard unit for measuring heat energy. A higher number does not guarantee a hotter grill — it means the burner uses more energy per hour. How that heat transfers to your food depends on burner design, grate material, and the cooking system (infrared vs open flame). Focus more on even heat distribution and burner count than a single BTU number. For example, the Royal Gourmet GA5401T puts out 61,000 BTU across 5 burners, while the Weber Spirit E-325 produces 19,000 BTU but reaches searing temperatures faster due to its Boost Burner design.
Porcelain-Enameled Cast Iron vs Stainless Steel Grates
Porcelain-enameled cast iron grates (found on the Weber Spirit E-325 and Captiva Designs 4-Burner) combine cast iron’s ability to hold and radiate heat evenly with a glass-like enamel coating that resists rust and makes scraping food residue easy. Stainless steel grates (Weber Genesis S-435) last longer against corrosion and do not chip, but they do not hold heat as well, so sear marks may be less defined. If you cook a lot of steaks and want strong grill marks, porcelain-coated cast iron is usually the better choice.

If you want to feed a crowd and love switching between gas, griddle, and charcoal, grab the Charbroil Pro Series 4-Burner with its 802.9 square inches of modular cooking area.
