🍔 The Complete Smash Burger Guide
Guide Updated June 2026
Smash burgers are the best burger most people can make at home, because the technique does the work. This guide covers everything: the science of the smash, the gear, the beef, and the exact steps to a lacy, crispy-edged crust every time.
What makes a smash burger different
A smash burger isn't just a thin burger. The defining move — smashing a loose ball of beef onto a screaming-hot surface — maximizes the contact between meat and metal. That contact triggers the Maillard reaction, the browning that creates hundreds of new savory flavor compounds. More contact means more crust, and the crust is the entire reason a smash burger tastes the way it does.
The gear you need
You don't need much, but two things matter: a flat, heavy cooking surface that holds high heat (cast iron or a flat-top griddle) and a sturdy press to smash with. A thin, stiff spatula for scraping under the crust rounds it out. That's it — no fancy equipment.
The right beef
Use 80/20 ground chuck. The 20% fat renders against the hot surface and crisps the edges; lean beef just dries out and won't crust properly. Don't season or compress the meat — roll it into loose balls and leave them alone until the moment they hit the heat.
Step-by-step method
- Heat cast iron or a griddle until ripping hot — a drop of water should vanish instantly.
- Place a loose 2–4 oz ball on the surface. Lay parchment over it and smash hard and flat for a full 10 seconds.
- Remove the parchment and season the top with salt and pepper. Don't touch it for ~2 minutes.
- When the edges are deep brown and lacy, scrape under it with a stiff spatula to keep the crust attached, then flip.
- Add cheese immediately and cook just 45–60 seconds more. Verify 160°F internal.
- Toast the bun in the rendered fat, build, and eat right away.
Single vs double
Because thin patties carry more crust, two thin patties beat one thick one. The classic move is a double smash: two 2 oz patties with cheese between and on top. Try our Double Smash Burger recipe.

Frequently asked questions
What surface is best for smash burgers?
A flat-top griddle or heavy cast iron skillet — both hold the high, even heat that creates the crust. Avoid thin pans that lose heat the moment the cold beef lands.
How thin should I smash a burger?
About 1/4 inch. Smash hard within the first 30 seconds; once the beef starts cooking it won't spread thin anymore.
Do I season before or after smashing?
After. Salt before smashing draws out moisture and can hurt the crust. Smash first, then season the top.
