Ingredients

Scale
  • 1 lb (450 g) ground beef, 80/20 blend
  • Salt and freshly ground black pepper, to taste
  • 1 tablespoon vegetable or canola oil
  • ½ cup (120 ml) mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon dill pickle relish
  • 1 teaspoon yellow mustard
  • ¼ teaspoon garlic powder
  • ¼ teaspoon smoked paprika (optional)
  • 1 teaspoon fresh lemon juice
  • 8 brioche slider buns
  • 8 slices American cheese (or cheddar/Swiss)
  • ½ small red onion, thinly sliced
  • 8 small leaves leaf lettuce
  • 8 thin tomato slices
  • Pickle slices (optional)

Instructions

  1. Make the special sauce: In a bowl, whisk together mayonnaise, ketchup, dill pickle relish, yellow mustard, garlic powder, smoked paprika, and lemon juice until smooth. Cover and refrigerate.
  2. Prepare toppings: Slice red onion thinly, wash and dry lettuce leaves, slice tomatoes, and prepare pickles if using. Set aside.
  3. Preheat your cast iron skillet or griddle over medium-high heat and add 1 tablespoon of oil. Heat until shimmering but not smoking.
  4. Form the beef into 8 loose balls (about 2 ounces / 60 g each). Season each ball lightly with salt and pepper.
  5. Place 2-3 balls on the skillet without overcrowding. Using a sturdy spatula, press each ball firmly down to about ¼-inch (6 mm) thickness. Let cook without moving for 2-3 minutes to form a crispy crust.
  6. Flip each patty carefully and immediately place a slice of cheese on top. Cook for another 1-2 minutes until cheese melts and patties are cooked through but still juicy.
  7. Slice brioche buns and toast them face-down in the skillet until golden brown and slightly crisp, about 1-2 minutes.
  8. Assemble sliders: Spread a generous spoonful of special sauce on the bottom bun, add a lettuce leaf, tomato slice, onion, cheesy patty, optional pickle slice, and top with the bun crown.
  9. Serve immediately while hot.

Notes

Do not overcrowd the pan to ensure crispy edges. Press patties firmly and quickly to lock in juiciness. Keep skillet hot for best crust. Toast buns separately to avoid sogginess. Special sauce tastes better after resting in fridge for a few hours or overnight.
