Ingredients

Scale
  • 1 pound (450g) ground beef (80/20)
  • Salt and freshly ground black pepper, to taste
  • 4 slices American or sharp cheddar cheese
  • 4 sturdy brioche or potato buns
  • 2 tablespoons butter, softened
  • ½ cup (120ml) mayonnaise
  • 1 tablespoon Dijon mustard
  • 2 tablespoons sweet pickle relish
  • 1 teaspoon smoked paprika
  • ½ teaspoon garlic powder
  • 1 teaspoon fresh lemon juice
  • Salt and pepper, to taste

Instructions

  1. Prepare the secret sauce by combining mayonnaise, Dijon mustard, sweet pickle relish, smoked paprika, garlic powder, lemon juice, salt, and pepper in a small mixing bowl. Stir well until smooth, cover, and chill in the fridge.
  2. Divide the ground beef into 4 equal portions (about 4 ounces or 115g each) and loosely roll each into a ball.
  3. Preheat your Blackstone griddle or cast iron skillet over medium-high heat for about 5 minutes until very hot but not smoking.
  4. Spread softened butter on the insides of the buns and toast them cut-side down on the hot griddle until golden brown, about 1-2 minutes. Remove and set aside.
  5. Place each beef ball on the griddle spaced apart. Using a sturdy metal spatula or burger press, firmly smash each ball down to about ¼ inch (0.6 cm) thickness. Hold for 10 seconds to sear. Season the exposed side with salt and black pepper.
  6. After 2-3 minutes, when edges are brown and crispy, flip each patty carefully. Immediately add a slice of cheese on top and cook for another 1-2 minutes until melted.
  7. Assemble the burger by spreading a generous spoonful of secret sauce on the bottom bun, placing the cheesy patty on top, adding preferred toppings (lettuce, tomato, pickles, onions), and capping with the top bun.
  8. Serve immediately while hot and juicy.

Notes

Use 80/20 ground beef for juiciness. Press patties firmly but not too thin (¼ inch). Toast buns with butter to prevent sogginess. Let secret sauce chill for best flavor. If patties stick, wait longer before flipping. Variations include adding chipotle powder for spice or using dairy-free mayo and cheese for vegan options.
