The Ultimate Smash Burger Recipe (On a Baking Steel)

Here's the thing nobody tells you about smash burgers: the burger isn't the secret. The surface is.

That deep, crispy, lacy crust the whole reason smash burgers exist, comes from smashing thin beef onto screaming-hot metal and letting full contact do the work. A grill grate can't do it; the fat drips through and the crust never forms. A thin pan can't hold the heat. You need mass, and you need conduction.

You need steel. And if you own a Baking Steel Original, you already have the best smash burger surface ever made sitting in your oven.

The Original Is a Smash Machine

Sixteen by fourteen inches of solid steel. That's four to six burgers at once, a whole family's dinner in one round. Throw it right on your grill and it turns any gas or charcoal setup into a flat-top. Inside, straddle it across two burners and do the same thing on your stove.

And here's the part I love: it's the same steel that makes your pizza. You don't need a Blackstone taking up half the patio or another single-purpose gadget in the cabinet. One slab, everything.

My summer go-to is the Original on the grill. All the smoke and sear, none of the kitchen haze, and when friends watch the steel go down on the grates, they lose their minds a little. If you want a lighter option for quick weeknight burgers inside, our Skinny Griddle and Mini Griddle are built for the stovetop. But the Original is the show.

What You Need

• 80/20 ground beef — the fat is the flavor and the crust. Don't go leaner.
• A Baking Steel Original (or Skinny/Mini for stovetop)
• A sturdy metal spatula — you'll scrape, not flip gently
• Something flat to smash with — a second spatula, a burger press, a small saucepan
• Parchment squares — between the smasher and the beef, zero sticking
• American cheese, potato buns, minced onion — the classics are classic for a reason

The Method

1. Get the steel ripping hot

On the grill: steel on the grates, lid down, burners high, 10–15 minutes. You want 450–500°F on the surface. Inside: straddle two burners on medium-high for 10 minutes. The preheat is not optional, a lukewarm steel steams the beef instead of searing it.

2. Ball the beef, don't pack it

Roll 2.5–3 oz balls, loose. The less you work the meat, the more tender the burger. Salt the outside generously right before they hit the steel, not before, or you cure the surface and lose the crumble.

3. Smash hard, smash once

Balls on the steel, parchment square on top, then smash down HARD, thinner than you think, edges almost lacy. You get one smash, in the first 30 seconds, while the fat is still cold. That's what welds the beef to the steel and builds the crust. Smash later and you just squeeze the juice out.

4. Leave it alone

One minute, no touching. The crust is forming underneath. When the edges go deep brown and juice pools on top, scrape, get the whole spatula under it and take the crust with you. That crust IS the burger.

5. Flip, cheese, stack

Flip, cheese immediately, 45–60 more seconds. Doubles beat singles, two thin crusty patties out-eat one thick one every time. Stack on a toasted potato bun and go.

Why Steel Beats Everything Else

The physics are simple: smash burgers are a heat-transfer problem. Steel holds enormous thermal energy and dumps it into the beef on contact, the same conductivity that gives your pizza its char gives your burger its crust. Grates lose the fat. Thin pans lose the heat when cold beef hits. Cast iron works but you can't fit six burgers on a skillet. The Original does the whole cookout in two rounds.

FAQ

Can I make smash burgers on a Baking Steel?

It's one of the best surfaces there is. The Original's mass and conductivity create the deep, crispy crust smash burgers are famous for — on the grill or straddling two burners inside. Its 16x14 surface fits 4 to 6 burgers at once.

Can I use the Baking Steel on a grill?

Yes — the Original turns any gas or charcoal grill into a flat-top. Set it on the grates, preheat 15 to 20 minutes with the lid down, and cook. All the outdoor smoke and sear with full steel contact.

What's the best surface temperature for smash burgers?

450 to 500°F. Hot enough for a hard sear in about 2 minutes per side. Preheat the steel a full 10 to 15 minutes on the grill or 10 minutes on the stove.

Which Baking Steel is best for smash burgers?

The Original — the biggest surface, the most heat mass, and it doubles as your pizza steel. For quick stovetop burgers, the Skinny Griddle and Mini Griddle are lighter, easier-to-handle options.

What started as a Kickstarter project (backed after an endorsement from Kenji López-Alt on Serious Eats) has grown into the go-to tool for hundreds of thousands of home pizza makers. Every Baking Steel is still made at the family shop.

Before launching Baking Steel, Andris trained under renowned chef Todd English and spent 15 years in the family steel business. He's the co-author of Baking with Steel with Jesse Olson Moore.

Today he teaches thousands of students how to make pizzeria-quality pizza at home through his free online classes and recipes.

In 2026, Andris launched the 72-Hour Pizza Dough Mix the same recipe he's been teaching for over a decade, now in a bag. Just add water.
