Smash Burgers
Loose balls of beef smashed thin on a screaming-hot griddle for maximum crust.
What's going on here
The entire idea behind a smash burger is surface area: flattening a loose ball of ground beef hard against a screaming-hot surface forces immediate, total contact between the meat and the heat, producing browning far more extensive than a thicker, gently-cooked patty could achieve in the same short time. That's also why the beef is handled as little as possible before smashing — a lightly packed, loosely formed ball, not a pre-shaped patty — since the smash itself is what compacts it, and pre-compacting first would only fight against the smash creating those characteristic craggy, well-browned edges. Because the patties are thin, they cook through fast enough that 71°C, ground beef's safe minimum, is easily reached well within the couple of minutes each side needs to brown properly — thin patties are, if anything, one of the more foolproof ways to guarantee ground beef reaches a safe temperature without overcooking, since there's very little total mass for the heat to travel through.
Ingredients
Patties
- 1.25 lbGround beef, 80/20
loosely divided into 4 balls, not pre-formed patties
- 1 tspSalt
- 1/2 tspBlack pepper
Finish
- 4American cheese slices(optional)
- 4Burger buns
- 1Sliced onion, pickles, sauce(optional)
Instructions
Prep
- Loosely divide the beef into 4 balls, about 5 oz each, handling as little as possible. Don't pre-form them into patties.
Tip: The smash itself does the shaping — packing them into patties beforehand compacts the meat before it even hits the heat, working against the crust you're trying to build.
Cook
- Heat a griddle or heavy skillet over high heat until genuinely smoking hot.
- Place the balls on the hot surface, immediately press flat and hard with a sturdy spatula (or a burger press), and hold for a few seconds.
Tip: Smash once, firmly, right away. Repeated pressing later just squeezes out juices without adding more crust.
- Season the exposed top with salt and pepper. Cook until deeply browned and crusted on the bottom.
- Flip, top with cheese if using, and cook until the second side is browned and the centre reaches 71°C (160°F).
Tip: Thin patties like these reach a safe temperature fast — check with a thermometer inserted from the side if you're unsure, since there's very little thickness for it to travel through.
Assemble
- Build on toasted buns with whatever toppings you like.

Tips for this recipe
Crust didn't develop
The surface wasn't hot enough, or the beef was smashed more than once. A single hard press onto a genuinely hot, smoking surface is what builds the crust — repeated pressing just squeezes out juice instead.
80/20 fat content matters here
Leaner beef has less fat to render and crisp at the edges during the smash, and tends to turn dry and crumbly on a surface this hot. Don't reach for lean ground beef for this particular method.
