Recipe Information
Ingredients
- 1 lb ground beef
- 1 tsp salt
- 0.5 tsp black pepper
- 0.5 tsp garlic powder
- 0.5 tsp onion powder
- 2 tbsp milk
- 2 tbsp panko breadcrumbs
- 1 cup finely diced onion
- 12 pieces Hawaiian rolls or slider buns
- 6 pieces slices of American cheese
- 12 pieces pickle slices
- 2 tbsp butter
- 2 tbsp water
Instructions
In a mixing bowl, combine the ground beef, salt, black pepper, garlic powder, onion powder, milk, and panko breadcrumbs. Mix until just combined, without overworking the meat.
Line a 9x13-inch baking sheet with parchment paper. Press the seasoned beef mixture evenly across the sheet until it forms a thin, flat layer.
Use the blunt edge of a knife to score the beef into 12 even squares, but do not cut all the way through. This will help separate the sliders later.
Sprinkle the finely diced onion evenly over the beef and press them gently into the meat.
Preheat the oven to 400°F (200°C). Place the beef and onion tray into the oven and bake for 10-12 minutes, or until the beef is fully cooked.
While the beef is baking, slice the Hawaiian rolls or slider buns horizontally in half and set aside.
When the beef is done, carefully drain any excess grease from the pan. Lay the slices of American cheese evenly across the beef, covering all 12 sections.
Place the pan back in the oven for 1-2 minutes, or until the cheese has melted.
Using a knife, cut along the scored lines to separate the sliders into squares.
Melt the butter in a small pan or microwave, then brush it onto the cut sides of the slider buns.
To assemble, place one piece of the beef and cheese onto the bottom half of each bun, top with a pickle slice, and cover with the top half of the bun.
Serve immediately and enjoy your homemade Mock Sliders White Castles!
