4 double-patty burgers

Ingredients

  • 1.5 lb ground beef, 80/20 fat ratio
  • 1 tsp kosher salt, divided
  • 1/2 tsp black pepper, divided
  • 8 slices American cheese
  • 4 soft hamburger buns
  • 2 tbsp unsalted butter, softened
  • 1/2 cup mayonnaise
  • 2 tbsp yellow mustard
  • 1 dill pickle, sliced
  • 1/2 yellow onion, thinly sliced

Instructions

  1. Divide the ground beef into 8 loosely formed balls, about 3 oz each, handling the meat as little as possible; overworking ground beef makes tough, dense patties.
  2. Do not season the balls yet; salt will be added right before they hit the grill so it does not draw out moisture too early.
  3. Preheat the grill to very high heat, 450-500F, using a flat griddle attachment or a well-oiled cast iron skillet placed directly on the grill grates if you have one, since smash burgers need a solid hot surface rather than open grates.
  4. Toast the cut sides of the buns with butter directly on the grill for 30-60 seconds until golden, then set aside.
  5. Place a beef ball on the hot surface and immediately press it flat with a sturdy spatula or a smash tool, holding pressure for 10-15 seconds until it spreads to about 4-5 inches wide and very thin.
  6. Season the exposed top of each patty immediately with a pinch of salt and pepper.
  7. Let the patties cook undisturbed for 90 seconds to 2 minutes; you will see a deep brown, crispy, lacy crust forming on the bottom edges, which is the whole point of the smash technique.
  8. Flip each patty once with a thin spatula, scraping firmly to capture all the crispy bits, then immediately top with a slice of American cheese.
  9. Cook the second side for about 60-90 seconds more, just until the cheese is fully melted and the center is no longer pink; ground beef should reach a safe internal temperature of 160F.
  10. Stack two smashed patties together per burger for a classic double, or serve single patties for a smaller portion.
  11. While patties finish, stir together mayonnaise and mustard for a quick burger sauce.
  12. Spread the sauce on the toasted bottom bun, add the cheesy patties, top with pickle slices and thin onion, and close with the top bun.

Highlights

  • Thin smashed patties get maximum crispy, caramelized crust
  • Loosely packed meat and one flip keep the inside tender
  • Ready in about 25 minutes total, great for weeknights
Tip: Do not press the patties down again after the initial smash; every extra press squeezes out juice and dries out the burger.
Tip: Use a griddle or flat cast iron surface rather than open grates so you do not lose the crispy smashed crust through the gaps.
