The incredibly simple combination of a ground beef burger resting in a soft bun remains the undisputed champion of the American backyard cookout. Elevating this beloved nostalgic classic from merely good to truly unforgettable requires a fundamental understanding of culinary science and precise technique.
The smash burger has rapidly become the absolute darling of backyard cookouts and high end diners alike. Thin patties with irresistible deeply charred edges deliver the maximum amount of flavor in every single bite thanks to the Maillard reaction a complex chemical process where amino acids and reducing sugars react under intense heat to create hundreds of entirely new flavor compounds.
Whether you are seeking the lacy impossibly crispy edges of a perfectly executed smash burger or attempting to recreate a diner classic this recipe will transform your Labor Day grilling game.
Ingredients
- 1.5 lbs coarse ground beef chuck (80/20 or 75/25 fat ratio)
- Kosher salt and freshly cracked black pepper
- 8 slices high quality American cheese
- 4 soft brioche or potato buns
- 2 tablespoons unsalted butter, softened
- 1 large yellow onion, very thinly sliced
- 1/2 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon sweet pickle relish
- 1 teaspoon yellow mustard
- Shredded iceberg lettuce
Instructions
Prepare the Sauce: In a small bowl whisk together the mayonnaise ketchup sweet pickle relish and yellow mustard. Set the burger sauce aside in the refrigerator.
Form the Beef: Do not pack the meat tightly. Gently form the loose ground beef into 8 equal sized jagged balls slightly smaller than a standard tennis ball roughly 3 ounces each. Keep them refrigerated until ready to cook.
Toast the Buns: Lightly butter the cut sides of the buns. Heat a heavy cast iron skillet or flat steel griddle over medium heat. Toast the buns until golden brown and crispy around the edges. Set aside.
Get the Griddle Screaming Hot: Increase the heat under your cast iron skillet or griddle until it is screaming hot almost smoking. Do not add oil to the pan.
Smash the Burgers: Place two burger balls onto the dry hot surface. Immediately smash them completely flat using a heavy stiff spatula. You can use a second spatula or a heavy press to push down on the first for extra leverage.
Season and Sear: Season the smashed patties generously with kosher salt and black pepper. Cook undisturbed for exactly two minutes until a deeply browned lacy crust forms on the bottom.
Flip and Cheese: Use a sharp metal spatula to scrape aggressively under the crust separating it from the griddle then flip. Immediately place a slice of American cheese on each patty.
Steam Melt: Cover the burgers with a metal dome or a piece of foil and allow the cheese to steam melt for exactly one to two minutes.
Stack and Assemble: Stack one cheesy patty on top of the other. Spread the burger sauce on the toasted bottom bun add a layer of shredded lettuce place the double patty on top add thinly sliced onions and cap with the top bun.
Chef's Pro Tips
The Essential Meat Blend
For true smashburgers you must use a significantly higher fat content of twenty to twenty five percent. This extra fat is crucial to prevent the extremely thin patties from drying out during the violent smashing process.
Do Not Pack the Meat
Never pack the meat tightly when forming the balls. Leaving the ground beef loose creates jagged edges that crisp up incredibly well when smashed against the hot iron.
The Scrape is Critical
The entire point of a smash burger is the deeply caramelized crust. You must use a sharp stiff metal spatula to aggressively scrape the patty off the griddle before flipping ensuring the crust stays attached to the meat.
