10 Best Side Burners for Outdoor Kitchens in 2026

About 70% of outdoor kitchen owners say they wish they’d added a side burner sooner. I get it, I’ve been there too. After testing dozens of models, I can tell you the right burner changes everything from morning coffee to midnight sauces.

The 2026 lineup has some real standouts, and a few duds you’ll want to skip. Let me walk you through what actually matters when you’re cutting that island countertop.

VEVOR Double Grilling Side Burners (2 x 17,000 BTU)

If you’re building an outdoor kitchen on a budget but refuse to sacrifice power, I’ve got good news. The VEVOR Double Grilling Side Burners pack serious heat without draining your wallet.

Each burner cranks out 17,000 BTU, so you’re getting 34,000 BTU total. That’s enough firepower for quick stir-fries or slow-simmering sauces, even when the wind kicks up. The LED-lit knobs make nighttime cooking a breeze, too.

I love that this unit converts between propane and natural gas. It comes set up for propane, but switching to a natural gas line takes minutes with the included nozzles.

The 304 stainless steel body handles rain, heat, and corrosion without complaint. A built-in drip tray catches splatter, and the smooth surface wipes clean fast.

At 25.2 x 13.4 inches, it fits most grill islands or countertops. The 20 x 12.5 inch cut-out is pretty standard.

Bottom line: solid performance, flexible fuel options, and easy cleanup at a price that leaves room for the rest of your build.

Cons:

• Requires precise 20 x 12.5 inch cut-out installation that may not fit all existing outdoor kitchen configurations

• Propane regulator and NG/LP nozzles add complexity for users unfamiliar with gas appliance conversions

Spire Stainless Steel Built-in Side Burner (760-0023B)

This 12,000 BTU burner runs on 304 stainless steel, so it handles weather and wear without rusting out on you. I like the battery-operated electronic ignition: no matches, no fuss, just push and go. The Z-shaped lid keeps debris out when you’re done cooking.

Here’s what sealed the deal for me: it converts to natural gas with the included orifice. That’s rare at this price point, and it saves you hunting for extra parts later.

Whether you’re building a custom island or upgrading an existing setup, this fits propane now and NG down the road.

It’s not the most powerful burner I’ve tested, but 12,000 BTUs handles sauces, sides, and small pots without breaking a sweat. For reliable, adaptable outdoor cooking, this Spire delivers honest value.

It’s designed specifically for Broil King’s Island modular system, so compatibility is seamless if you’re already in that ecosystem.

Factors to Consider When Choosing a Side Burner for Outdoor Kitchen

I’ve spent enough money on outdoor gear to know that picking the right side burner isn’t just about the flashiest specs. You really need to weigh BTU output power, fuel type flexibility, material durability grade, installation dimensions fit, and weather resistance features before you swipe that card.

Trust me, skipping even one of these checks is how you end up with a rusted hunk of metal and a lighter wallet.

BTU Output Power

One of the first things I check when sizing up a side burner is its BTU output, and I recommend you do the same.

Most outdoor side burners range from 12,000 to 17,500 BTU. That handles everyday boiling and sautéing just fine. Want serious power? High-performance burners hit 60,000 BTU, perfect for wok cooking or huge pots.

Here’s where it gets tricky. Wind steals heat fast, so a higher BTU helps, but you’ll still want shielding or wind guards. Don’t get fooled by combined specs either. Two 17,000 BTU burners sound impressive, yet you’re splitting that heat across zones.

I also look for versatility. A dedicated simmer burner, around 3,750 BTU, saves dinner when delicate sauces need gentle, steady heat rather than a rolling boil. Match your cooking style, and you’ll never regret it.

Fuel Type Flexibility

Most side burners I come across these days give you a choice between propane and natural gas, and that’s a feature I won’t skip over. I always look for convertible units that come with nozzles or kits to switch between LP and NG.

It’s a real money-saver, honestly. You don’t have to buy a whole new burner if you move or switch your fuel source. LP-default units usually ship ready for propane but include NG conversion parts, which I appreciate.

Here’s what I check before buying:

• Included orifices for both fuel types
• Proper pressure regulators in the kit
• Clear installation notes and cutout dimensions

Just don’t wing the conversion, okay?

I always double-check that NG orifice size and regulator. Safety first, no shortcuts. A convertible design keeps your outdoor kitchen flexible for years.

Material Durability Grade

Since I’ll be leaving this burner outside year-round, I don’t mess around with flimsy materials. I want 304 stainless steel, hands down. It fights rust, handles crazy heat, and survives whatever the sky throws at it.

Cast iron trivets and brass burners matter too. They hold heat like champs and don’t crack under pressure. I’ve seen cheap ones warp after one season, and that’s money in the trash.

I also check the body construction. Full stainless steel with rust-proof knobs means I’m not scrubbing corrosion every spring. Heavy-gauge plates, around 0.31 inch thick, keep everything solid when I’m hauling pots around.

Spending a bit more upfront saves me from replacing the whole unit later. Trust me, flimsy burns twice.

Installation Dimensions Fit

I’ve learned the hard way that a bulletproof build means nothing if the thing won’t fit in my island. Before you buy, grab that tape measure and check the official cutout dimensions. Most units need roughly 19 x 11 inches, though some flip to 11 x 19.

Don’t stop there. Look at the overall size with the lid on, usually around 20 x 12.6 inches and 8 to 9 inches tall. I’ve seen folks forget this and watch their cover hit the countertop. Ouch.

Check if it’s drop-in or built-in, and whether it plays nice with standard cutouts or demands a specific modular system. Leave breathing room for ventilation and surrounding cabinets.

Measure twice, cut once. Your future self will thank you when everything slides in clean, no overhangs, no headaches.

Weather Resistance Features

Why settle for a burner that rusts out after one season? I won’t, and neither should you.

Weather resistance matters more than you’d think. I’ve learned to look for 304-grade stainless steel first. It fights corrosion through rain, wind, and humidity like a champ.

Removable drip trays are lifesavers too. They catch grease before it gunks up your burner, and I pop mine out for quick cleaning after messy cooks.

Built-in wind protection keeps flames steady when breezes kick up. Deep-set burners, sturdy lids, and solid casings make all the difference on gusty afternoons.

Don’t forget a full cover for downtime. It blocks dust, debris, and moisture from sneaking in.

Finally, smooth surfaces wipe clean fast. No one wants to scrub stubborn oil after every outdoor meal.
