Learn how to make the perfect crispy, juicy smash burger at home! This easy recipe features a magical savory mix-in for the beef and a tangy secret sauce you will want to put on everything.

Ingredients

For the Meat Mix-In:

  • 4 tbsp unsalted butter, melted

  • 1 tbsp Worcestershire sauce

  • 1 tsp smoked paprika

For the Burgers:

  • 1 lb ground beef (80/20 blend)

  • 4 thick slices deli American cheese

  • 4 Brioche buns, buttered for toasting

  • Salt and black pepper, to taste

For the House Sauce:

  • 1/2 cup mayonnaise

  • 2 tbsp ketchup

  • 1 tsp creamy horseradish

  • 1 tsp Worcestershire sauce

  • 1 tsp sriracha (or hot sauce)

  • 1/2 tsp smoked paprika

  • 1 clove garlic, finely minced (or 1/2 shallot)

Classic Toppings:

  • Fresh lettuce leaves

  • Sliced tomatoes

  • Dill pickle slices

Instructions

  • Prep the Sauce: In a small bowl, whisk together all the House Sauce ingredients until smooth. Set aside in the fridge.

  • Flavor the Beef: In a separate small bowl, mix the melted butter, Worcestershire, and smoked paprika. Pour this over your ground beef and gently mix with your hands.

  • Form Balls: Divide the beef into 4 equal portions and gently roll them into loose balls. Place in the fridge for 20 minutes to chill.

  • Toast Buns: Toast the buttered brioche buns in a skillet over medium heat until golden. Set aside.

  • Get Hot: Heat a large cast iron skillet or flat griddle over medium-high heat until it is smoking hot.

  • Smash: Place the cold meatballs onto the hot pan (work in batches if needed). Top each with a square of parchment paper. Firmly press down with a heavy flat spatula to smash them thin. Peel off the paper.

  • Season & Cook: Season generously with salt and pepper. Let sizzle undisturbed for about 2 minutes until the edges are crispy and dark brown.

  • Flip & Melt: Flip the patties. Immediately place a slice of American cheese on top. Cook for 1 more minute until melted.

  • Assemble: Spread the house sauce on the toasted buns. Layer with lettuce, pickles, tomatoes, and the hot cheesy patty. Serve immediately!
