Ingredients

Instructions

  1. Step 1: In a large bowl, combine 1 lb ground beef, 1 tbsp espresso powder, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper. Mix gently until just combined, then form into eight 2-inch diameter patties.
  2. Step 2: Heat 2 tbsp unsalted butter in a large skillet over medium-low heat. Add 1 large thinly sliced yellow onion and cook, stirring occasionally, for 20 minutes until deeply golden and caramelized.
  3. Step 3: Increase heat to medium-high and add beef patties to the skillet. Cook 3-4 minutes per side for medium doneness, placing 1/2 slice cheddar cheese on each patty during the last minute to melt.
  4. Step 4: Toast 8 mini slider buns in the skillet for 1 minute until golden.
  5. Step 5: Assemble sliders by placing each patty on a bun bottom, topping with caramelized onions, then covering with the bun top. Serve warm.
