Smash Burgers with House Sauce

  • Author: Lindsay
  • Total Time: 35 minutes
  • Yield: 4 burger patties 1x


The famous Smash Burger! Deeply crisped, craggy, juicy, squashed patties covered with melty cheese, piled on a buttery bun, and topped with a dreamy zip of secret sauce. 



Smash Burger Sauce (for mixing with the ground beef)

  • 4 tablespoons butter, melted
  • 1 tablespoon Worcestershire sauce
  • a couple swishes of fish sauce (about 1 teaspoon)
  • 1 teaspoon smoked paprika

Burger Essentials

  • 1 lb. ground beef (80/20 is ideal)
  • 4 Brioche buns
  • 4 slices American cheese (the good kind from the deli)
  • House Sauce (see notes for recipe – do not skip! this stuff is magical)

Toppings You Might Like

  • 1/2 onion, diced or sliced (sautéed for an extra level up)
  • 4 lettuce leaves
  • 1 tomato
  • 12 pickle slices


  1. Mix the smash burger sauce in a small bowl. In a larger bowl, place the ground beef and pour the sauce over. Mix with your hands to get it well-distributed through the meat. Form into 4 balls. Place the balls in the fridge for 20-30 minutes while you prep everything else. You can even pop it in the freezer for a few minutes – you just want them to be pretty cold so the butter mixture doesn’t immediately melt out everywhere once you start cooking them.
  2. Butter the buns and toast them on your skillet or griddle until golden.
  3. Prep the toppings and house sauce (see notes).
  4. Cut a small piece of parchment paper that you’ll use on top of the burgers to prevent sticking.
  5. Heat a cast iron skillet or flat griddle until it’s very hot; place a few of the burgers on the hot surface. Sprinkle them with a big pinch of salt and let them sit and sizzle for about 20 seconds. 
  6. Place the parchment paper on top of each burger and then, using a heavy, flat tool, press the burgers down as flat as you can get them in one swift motion. They’ll be super sizzly and splattery, but they should make a nice, round, thin smash burger shape on the griddle. (The ideal tool for this is a cast iron grill press, but a flat spatula can work in a pinch). Cook for a few minutes and then flip and top with cheese right away. Leave them undisturbed for another 1-2 minutes to melt the cheese and get a max amount of flavorful browning on the back side.
  7. Assemble your burgers! Mine is always a toasted brioche buns, mega flavorful smash burger patty (or 2), cheese, crispy lettuce, and a thick smear of that house sauce. Happy, happy summer.



House Sauce: Mix 1/2 cup mayo, 2 tablespoons ketchup, 1 teaspoon horseradish, 1 teaspoon Worcestershire, a quick squeeze of sriracha, 1/2 teaspoon paprika, half of a shallot, minced or grated (or sub a clove of grated garlic). Season with salt to taste. NEXT LEVEL.
