Smash Burger Recipe (Crispy Diner-Style Double Cheeseburger)
Easy smash burger recipe: thin beef patties smashed on a ripping-hot skillet for lacy crisp edges, melted American cheese and a tangy burger sauce.
This smash burger recipe gives you the crispy, beefy, cheese-dripping double cheeseburger you get at an old American diner, made at home in about 25 minutes. Instead of a thick patty cooked slowly, you press a loose ball of ground beef flat onto a screaming-hot pan, and that one move changes everything.
The smash burger is not a new trend. Diners and lunch counters across the United States have been pressing burgers on flat-top griddles for nearly a century, because thin patties cook fast and feed a line of hungry customers. The name simply describes the technique: you smash the beef. Burger chains and backyard cooks made it famous again in the last decade, and now it is one of the most searched burger styles in America.
The magic is the Maillard reaction. When raw beef is pressed hard against very hot steel or cast iron, almost the whole surface touches the metal at once. The edges turn into a lacy, deeply browned crust full of savory flavour, while the inside stays juicy because the patty cooks in under three minutes. Smash only once, in the first 30 seconds, while the meat is still cold; pressing later squeezes out the juices.
Use 80/20 ground chuck. The fat is what crisps the edges and keeps the burger moist, so lean beef gives you a dry, grey patty. Season only the outside, right after smashing, with plenty of salt and pepper. American cheese is the classic choice because it melts into a glossy blanket, but cheddar or pepper jack also work. For a halal burger, use halal ground beef; for a gluten-free version, swap the bun for a gluten-free bun or a lettuce wrap.
A soft potato roll or brioche bun toasted in butter, thin-sliced onion, pickles and a quick sauce of mayo, ketchup, mustard and pickle brine are all you need. Serve your smash burgers with crispy fries, onion rings, coleslaw or a cold milkshake for the full diner experience.

Ingredients
- 600 g ground beef chuck (80% lean, 20% fat)Substitute: halal ground beef
- 4 soft burger buns (potato or brioche)Substitute: gluten-free buns or lettuce leaves
- 8 slices American cheeseSubstitute: cheddar or pepper jack
- 1 small white onion, very thinly sliced
- 2 tbsp butter, softened, for the buns
- 1 tsp fine salt
- 1 tsp freshly ground black pepper
- 1 tbsp neutral oil (canola or vegetable)
- 16 dill pickle slices
- 4 tbsp mayonnaise
- 2 tbsp ketchup
- 1 tbsp yellow mustard
- 1 tbsp pickle brine or finely chopped pickles
- 4 leaves iceberg lettuce (optional)
Method
- Make the burger sauce. Stir the mayonnaise, ketchup, mustard and pickle brine together in a small bowl and keep it in the fridge until serving.
- Portion the beef. Divide the cold ground beef into 8 loose balls of about 75 g each. Do not pack them tightly and keep them in the fridge until the pan is hot.
- Toast the buns. Spread the cut sides of the buns with butter and toast them in a large cast-iron skillet or griddle over medium heat until golden, then set aside.
- Heat the pan very hot. Wipe the skillet, add a thin film of oil and heat it over high heat until it just starts to smoke.
- Smash the patties. Place 2 to 4 beef balls in the pan, lay a piece of parchment on top and press each one down hard with a sturdy metal spatula into a thin patty about 6 mm thick. Smash once only and season the tops with salt and pepper.
- Sear without moving. Let the patties cook untouched until the edges are deeply browned and lacy and the top looks almost cooked through.
- Flip and add cheese. Scrape under each patty with the spatula to keep the crust, flip it, add a few onion slices if you like and lay a slice of cheese on top. Cook until the cheese melts.
- Stack the doubles. Stack two cheesy patties on top of each other and move them to a plate. Repeat with the remaining beef, wiping the pan between batches if it gets too smoky.
- Build the burgers. Spread sauce on both bun halves, add lettuce and pickles to the bottom bun, top with a double patty stack and the top bun. Serve right away while the edges are still crisp.
Keep the beef cold and the pan as hot as you can safely get it, because the contrast is what creates the crust. A cast-iron skillet, carbon-steel pan or outdoor griddle works best; non-stick pans cannot handle the heat. Use a stiff, sharp-edged metal spatula and a piece of parchment between the spatula and the beef so the meat does not stick when you press. Do not crowd the pan: two to four patties at a time keeps the temperature high. If you want extra flavour, try an Oklahoma-style onion burger by smashing a handful of paper-thin onions right into the raw patty.
Frequently asked questions
What is a smash burger?
A smash burger is a thin burger made by pressing a ball of ground beef flat onto a very hot griddle or skillet. The pressing creates a large, crispy, deeply browned crust while the thin patty cooks quickly and stays juicy.
What is the best beef for smash burgers?
Use 80/20 ground chuck, which is 80 percent lean meat and 20 percent fat. The fat crisps the edges and keeps the patty moist. Very lean beef makes dry, crumbly smash burgers.
How thin should a smash burger be?
Press each 75 g ball to about 6 mm thick, roughly 10 to 12 cm wide. Thin patties give you more crust and cook in about 3 minutes total.
Can I make smash burgers in a regular frying pan?
Yes, a heavy cast-iron or carbon-steel frying pan works perfectly. Avoid non-stick pans, because they should not be heated high enough to get a proper sear.
Why does my smash burger stick to the spatula?
Raw beef sticks to metal. Place a square of parchment paper on the beef ball before pressing, then peel it off. A clean, sturdy spatula also helps.
What cheese is best on a smash burger?
American cheese is the classic choice because it melts quickly and smoothly over the hot patty. Cheddar, Swiss or pepper jack also taste great, though they melt a little slower.
