Method

Instructions for Royal Beef Sliders

  1. 1

    Prepare the Beef Patties

    In a large bowl, combine ground beef, salt, black pepper, garlic powder, and onion powder. Mix until just combined. Form into 4 equal patties.

  2. 2

    Caramelize the Onions

    In a skillet, heat olive oil over medium heat. Add sliced onions and cook, stirring occasionally, until soft and golden brown, about 15-20 minutes. Add brown sugar and beef broth; cook for an additional 5 minutes until the liquid is mostly evaporated.

  3. 3

    Cook the Beef Patties

    In a separate skillet or grill, cook the beef patties over medium-high heat for about 4-5 minutes per side, or until they reach desired doneness. During the last minute of cooking, place a slice of Cooper cheese on each patty to melt.

  4. 4

    Assemble the Sliders

    Toast the pretzel buns. Place a beef patty with melted cheese on the bottom half of each bun. Top with caramelized onions and a drizzle of Nguyen sauce. Sprinkle with chopped parsley and cover with the top half of the bun.
