Best Gas Grills Under $400 (2026 Buyer’s Guide)

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.

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.

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

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.

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:

Preheat Speed

The Monument Mesa II hit 500°F in under 6 minutes — the best in this group. The Nexgrill hit 450°F in about 8 minutes. The Weber Q 3200 was slower to climb but maintained temperature more steadily once there.

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.

Grease Management

The Monument’s grease management system funneled drippings cleanly to the collection tray. The Nexgrill’s tray is easy to remove and clean. The Weber Q 3200 has Weber’s famously well-designed drip system — simple and effective.

Frequently Asked Questions

What is the best gas grill under $400?

For most people, the Monument Mesa II 415BZ is the best overall gas grill under $400 in 2026. It combines 4 burners, a dedicated sear zone, solid construction, and a 10-year warranty at a price point that usually lands under $400. If budget is the primary concern, the Nexgrill 720-0925P delivers incredible cooking area and basic performance for around $279.

Are cheap gas grills worth buying?

They can be — with realistic expectations. A grill in the $200–$250 range will cook burgers and hot dogs just fine. But if you want to smoke, sear, or cook large pieces of meat properly, you need at least $300–$400 and a grill with better build quality. The cheap ones also tend to develop problems after 2–3 seasons.

How long should a gas grill last?

A budget grill ($200–$300 range) typically lasts 2–5 years with basic care. A mid-range grill ($350–$400+) with proper maintenance can last 6–8 years or more. Weber and Napoleon grills are known to last 10+ years. The biggest factors: how often you clean it, whether you use a cover, and the quality of the burners.

Is a 2-burner grill enough?

For 1–4 people, a 2-burner grill is absolutely enough. You can still do two-zone cooking with two burners, and most 2-burner grills in this price range have 280–350 sq. in. of cooking space — plenty for a family meal. If you regularly cook for groups of 6+, go for 3 or 4 burners.

What’s better — Nexgrill or Weber?

Weber is better in almost every measurable way: durability, heat consistency, burner longevity, and long-term value. But Weber costs significantly more. Nexgrill wins on upfront value and cooking area per dollar. If you’re a casual griller who replaces their grill every 4–5 years anyway, Nexgrill makes sense. If you want a grill that lasts a decade, buy Weber.

Are natural gas conversion kits safe?

The honest answer: not always. Conversion kits from unknown brands can be inconsistent in pressure ratings and orifice sizing, which creates safety risks. Even reputable conversion kits may void your grill’s warranty. If you need natural gas, buy a purpose-built natural gas model. The extra cost is worth it for the safety and reliability.
