Best Gas Grills Under $400 (2026)
12 min read
Let me be straight with you: I’ve cooked on a lot of cheap grills. Some were fine. Some were an embarrassment — thin shells that rattled in the wind, ignitions that failed after two months, and BTU numbers big enough to impress anyone who doesn’t know better.
But here’s what I’ve learned after 10 years of testing, owning, and occasionally cursing at gas grills: the $400 price point is where things start to get real.
Under $400, you can now find grills with solid stainless burners, decent heat retention, genuine searing capability, and warranties that actually mean something. You don’t need to spend $700 to get a grill that performs — but you do need to know what to look for and what to run from.
This guide cuts through the marketing noise. I’m not here to sell you the shiniest grill on the shelf. I’m here to help you buy the right one for your backyard, your family, and your budget — and make sure you’re still happy with it three summers from now.
The Monument Mesa II 415BZ is the best overall gas grill under $400, offering 4 burners, a dedicated sear zone, and a 10-year warranty for ~$379. For pure value and maximum cooking space, the Nexgrill 720-0925P at ~$279 is unbeatable.

Best Gas Grills Under $400 — Reviewed
Let’s get into the grills themselves. I’ll give you an honest breakdown of what each one does well, where it falls short, and most importantly — who it’s actually right for.
Monument Mesa II 415BZ
428 sq. in.
35,000
4 + Sear Zone
10 Years
If I had to recommend one grill in this entire price range for someone who wants to cook seriously — not just grill burgers on a Saturday afternoon — it would be the Monument Mesa II 415BZ. And it’s not a close call.
Here’s the reality: most grills under $400 give you four burners OR decent build quality OR a sear zone. The Monument gives you all three. That’s rare.
- Hits 500°F in under 6 minutes — legitimate searing territory
- The dedicated sear zone is not a gimmick. Proper crust on ribeyes
- Build quality is noticeably better than most Nexgrill models at similar price
- That 10-year warranty tells you Monument believes in this grill
- Stainless steel construction feels solid, not tinny
- Assembly takes about an hour — set aside the time
- Side shelves could be sturdier — they flex a little under weight
- Not the largest cooking area if you’re feeding a big crowd regularly
I smoked a spatchcocked chicken on this grill using indirect heat — one side on low, one side off — and the results were excellent. Skin was crispy, internal temp hit 165°F evenly, no hotspots. For steaks, the sear zone gets hot enough to get that crust without having to crank all four burners.
Anyone serious about backyard cooking who doesn’t want to blow $600+ to get real performance.
You’re only grilling 4–5 times a year and just need something basic. Save $100 with the Nexgrill below.
Nexgrill 4-Burner with Side Burner (720-0925P)
768 sq. in.
48,000
4 + Side
Standard
If the Monument is the overachiever, the Nexgrill 720-0925P is the smart shopper’s pick. It’s usually priced between $250–$299, which means you’ve got budget left over for a grill cover, a propane tank, and a solid set of BBQ tools.
- Huge cooking area — 768 sq. in. is genuinely roomy for groups
- The side burner is actually useful for sauces, corn, or keeping things warm
- Preheats quickly and gets plenty hot for everyday grilling
- Incredible cost-per-burger value — unmatched at this price
- Widely available at Home Depot, easy replacement parts access
- The heat tent shields (flavourizer bars) will likely rust in about 3 years
- Thinner metal body compared to Weber or Monument — you’ll feel it
- Less consistent heat distribution — some hotspots near the back burner
First-time homeowners, casual grillers, and anyone who wants maximum cooking space without stretching the budget.
You’re serious about BBQ craft or live somewhere with harsh winters and plan to leave the grill outside year-round.
Char-Broil Performance Series FlavorMax 2-Burner
300 sq. in.
24,000
2
Standard
Most compact grills are a compromise. You get limited space, uneven heat, and the experience of cooking on something that feels like an afterthought. The Char-Broil FlavorMax 2-Burner is a genuine exception to that rule — and I want to be clear, because I was skeptical before I cooked on it.
- FlavorMax convection technology actively circulates heat more evenly than standard small grills
- Foldable side shelves make storage easy — this fits in tight spaces without fuss
- Better hotspot control than I expected from a 2-burner compact unit
- Porcelain-coated cast iron grates retain heat well and are easy to clean
Apartment balconies, small patios, couples, or anyone who grills for 1–2 people most of the time.
You’re feeding more than 4 people regularly or want the option to do bigger cooks like brisket or whole chickens.
Weber Q 3200
393 sq. in.
21,700
2
Exceptional
Here’s something worth knowing in 2026: the Weber Spirit II E-310 — the gold standard for home grillers — regularly climbs to $450–$500 now. If you want Weber quality and you’re sticking to a $400 budget, the Weber Q 3200 is your move.
It’s a different kind of grill than the others on this list. But in the right hands, it’s exceptional.
You give up: cabinet storage, a side burner, and a massive cooking surface.
What you gain: a cast aluminum body that simply does not rust, Weber’s legendary burner consistency, and a grill that you can realistically expect to use for 8–10 years with proper care.
- Cast aluminum body — immune to rust, even in coastal or high-humidity climates
- Weber’s porcelain-enameled cast iron grates are among the best in the business
- Electric ignition is rock-solid reliable — I’ve never had a Weber ignition fail on me
- Excellent long-term investment, especially if you live somewhere with harsh weather
Anyone in a coastal area, humid climate, or rust-prone environment. Also ideal for buyers who want a grill they’ll still be happy with in 2031.
You need lots of cooking space, cabinet storage, or a side burner. Look at the Monument or Nexgrill instead.
Coleman RoadTrip 285
285 sq. in.
20,000
3
Standard
Most portable grills are glorified camp stoves. They get hot in one spot and nothing else. The Coleman RoadTrip 285 is in a different category, and it’s not really close.
I’ve cooked chicken thighs low and slow on this at a campsite using two-zone cooking — burners one and three on, middle off — and they came out properly cooked, not cremated. That’s what separates this from every other portable grill I’ve tried.
- Three independently controlled burners in a portable frame — genuinely rare
- Creates real indirect heat zones, meaning you can smoke or slow-roast, not just char
- Folds flat and rolls — genuinely easy to move
- Stands up to tailgating use, campsite use, and road trips without fuss
Tailgaters, campers, and anyone who wants a portable grill that can actually grill — not just heat things up.
This isn’t your primary backyard grill. If you’re grilling at home more than once a week, invest in one of the larger models above.
What You Can Actually Expect From a Gas Grill Under $400
I want to be honest with you, because nobody else in this space usually is.
The average lifespan of a budget gas grill — one in the $200–$350 range — is 2 to 5 years. Better-built grills in the $350–$400 range, maintained properly, can push 7–8 years. But there are things you simply cannot get at this price that you’d find on a $700–$900 grill:
- Consistent heat from edge to edge across the full grill surface
- Heavy-gauge stainless steel that resists warping over years of high-heat use
- Near-commercial-grade burner output and longevity
- Decent warranties — Monument’s 10-year warranty is a genuine standout
- Enough searing power for steaks, burgers, and chicken
- Real indirect heat capability for slow cooks
- Manageable assembly and reasonable durability if maintained properly
The biggest difference between a $300 grill and a $900 grill isn’t maximum temperature. It’s consistency and durability. Keep that in mind when setting expectations.
What to Avoid — Most Buyers Get This Wrong
The BTU Myth
Manufacturers love to put big BTU numbers on the box because consumers respond to them. Don’t fall for it.
What actually matters: burner material (stainless vs cast iron vs aluminized steel), the heat tent design, and the overall build quality of the firebox. Those things determine how well your food cooks — not the number on the box.
Thin Metal Bodies
If a grill feels tinny when you tap it in the store, it’ll struggle in the wind at home.
Thin metal does three things you don’t want: it leaks heat, warps under repeated high-heat use, and makes it nearly impossible to maintain stable cooking temperatures on a breezy day. You’ll burn more propane chasing a temperature you can’t hold.
Cheap Ignition Systems
A grill that won’t light reliably is a grill you’ll use less — and eventually stop using. Cheap piezo ignition systems are notoriously unreliable after 1–2 seasons, especially in damp climates. Look for electronic ignition with a proven track record (Weber is the standard here) and always buy a backup long-stemmed lighter just in case.
Fake Stainless Steel Marketing
“Stainless steel” on a cheap grill usually means stainless-look panels over a steel frame that will rust. Real stainless uses 304-grade steel throughout. Budget grills use 430-grade or lower, which can rust in humid or coastal conditions.
Key Buying Factors Before You Decide
Weight Matters More Than Most People Realize
Heavier grills retain heat better, resist warping, cook more evenly, and last longer. If you’re in a store comparing two grills side by side, lift the lid. The heavier option is usually the better build — though obviously weight alone isn’t everything.
Burner Count Explained
- 2 burners: Enough for couples and small families. Good for simple two-zone cooking (one side on, one off)
- 3 burners: The sweet spot for most people. Versatile enough for indirect cooking, entertaining, and everyday use
- 4 burners: Great for feeding groups. More cooking flexibility, but watch the build quality — 4-burner budget grills are where manufacturers cut corners most aggressively
Grill Grates — More Important Than You’d Think
The grates are where your food actually cooks, and they vary significantly in quality:
- Cast iron grates: Best heat retention and sear marks. Heavy, require seasoning, but last decades if maintained
- Porcelain-coated cast iron: Nearly as good as bare cast iron, easier to clean, resistant to rust
- Stainless steel rod grates: Durable and low-maintenance, but don’t retain heat as well — less impressive sear marks
- Porcelain-coated steel: Common on budget grills. Fine but prone to chipping, which leads to rust
Heat Distribution and Hotspots
Every budget grill has some variation in heat across the cooking surface. The question is how much. Ask yourself: can I cook chicken breasts across the whole grill and have them all hit 165°F at roughly the same time? On the better models here — the Monument and the Weber especially — the answer is yes. On cheaper models, you’ll find yourself constantly moving food around.
Warranty and Replacement Parts
A 1-year warranty on a budget grill is not reassuring. Monument’s 10-year warranty and Weber’s multi-year coverage are standouts. Also check that replacement parts (burners, heat tents, ignition) are available and reasonably priced. A grill you can’t get parts for is eventually a landfill donation.
Propane vs. Natural Gas Under $400
Best Propane Grill Under $400
Propane dominates this price category, and for good reason. Propane grills are portable, easy to set up, and deliver better consistent BTU output than natural gas at equivalent pressures. Every grill on this list runs on propane, and for most backyard cooks, that’s exactly what you want.
Standard 20 lb. propane tanks last roughly 18–20 hours of grilling — about a full summer of weekend use before you need a refill.
Are There Any Good Natural Gas Grills Under $400?
I’ll be blunt: not really. True natural gas grills under $400 are extremely rare, and the ones that do exist in this range usually involve compromises on build quality that make them poor value.
If you genuinely need natural gas, set a budget of at least $500–$600 and buy a purpose-built NG model. It’s not worth cutting corners on gas connections.
How These Compare to the Weber Spirit E-310
I can’t write a gas grill guide without talking about the Weber Spirit E-310. It’s the benchmark that everyone in this category gets compared to — and for good reason.
The Spirit E-310 has earned its reputation through consistent, reliable cooking performance, exceptional burner longevity, and build quality that outlasts most competitors by years. The GS4 grilling system (burners, ignition, flavorizer bars, and grease management) is genuinely excellent.
9.5
9.0
8.5
7.0
Key takeaway: budget grills can absolutely match Weber in features. Very few match Weber in longevity. If you’re buying a grill you plan to have for a decade, Weber is worth the extra money. If you’re in the $400 range and want the best available option, the Monument Mesa II 415BZ is the closest thing to Weber-level performance without the Weber price tag.
Best Gas Grills Under $450 — Is Spending More Worth It?
Sometimes an extra $50–$100 makes a meaningful difference. Here’s what you generally get when you move from the $400 to the $450 range:
- Thicker gauge metal on the firebox and lid
- Stronger, longer-lasting burners
- Better warranty coverage
- More consistent heat distribution out of the box
At the top of this range, two models stand out:
- Weber Spirit II E-310 (~$450–$499): If you can stretch the budget, this is the move. It’s the most reliable mid-range gas grill on the market
- Napoleon Rogue series (~$449+): Excellent build quality, solid warranty, slightly more feature-rich than Weber at a similar price point
Maintenance Tips That Will Double Your Grill’s Lifespan
Here’s something most people don’t think about until it’s too late: the grill you buy is only as good as the care you give it. I’ve seen $600 grills ruined in two seasons by neglect, and I’ve seen $300 grills last seven or eight years with basic maintenance.
- Get a Grill Cover — This is Non-Negotiable: A $30 grill cover can easily add 2–3 years to a budget grill. UV rays, rain, and winter freeze-thaw cycles destroy painted steel and accelerate rust. Cover it whenever it’s not in use.
- Clean the Grease Trap Regularly: Grease fires are the most common reason grills get damaged. A full grease tray doesn’t just create flare-up risk — it’s a fire hazard. Check it every few cooks and clean it out.
- Protect the Burners: At the end of the season, run the burners on high for 15 minutes with the lid closed to burn off residue. Then brush the cooking grates and check the burners for debris or spider webs. A clogged burner means uneven flame and hot spots.
- Prevent Rust Before It Starts: Season your cast iron grates with a thin layer of cooking oil before and after the grilling season. For the exterior, a light wipe with stainless cleaner once a month keeps painted or stainless panels in good shape. And again — use a cover!
Real-World Cooking Test Results
I ran these grills through the scenarios that actually matter for a home cook. Here’s what I found:
500°F
450°F ~8m
Steak Searing
For a proper sear on a 1.5″ ribeye, you need consistent high heat. The Monument’s dedicated sear zone delivered a proper Maillard crust. The Nexgrill got close at the hottest spot. The Weber Q 3200 surprised me — its cast iron grates retained so much heat that even without a dedicated sear zone, it produced excellent results.
Chicken Cooking Consistency
This is where budget grills typically fail — and where the Monument really stood out. I placed six bone-in chicken thighs across the grill surface. All six hit 165°F within 2 minutes of each other. On the Nexgrill, the ones near the back burner ran a few degrees hotter and I had to rotate them halfway through.
Wind Performance
Lighter grills struggle in the wind. The Monument and Weber held temperature well in moderate wind. The Nexgrill lost 50–75 degrees when a decent gust hit and took 3–4 minutes to recover. If you grill outdoors in a typically breezy spot, weight and build quality become even more important.
