Ingredients:

  • 12 oz Hawaiian sweet rolls
  • 1 lb deli roast beef, thinly sliced
  • 8 oz Provolone cheese, sliced thin
  • 4 tbsp unsalted butter, melted
  • 1 tsp garlic powder
  • 2 large yellow onions, thinly sliced
  • 2 tbsp unsalted butter
  • 1 tbsp olive oil
  • 1/2 tsp salt
  • 2 cups beef broth, low sodium
  • 1 tbsp Worcestershire sauce
  • 1 clove garlic, minced
  • 1/4 tsp black pepper

Instructions:

  1. Place a skillet over medium heat with 2 tbsp butter and olive oil. Add the sliced onions and salt, cooking for 15–20 minutes until mahogany-colored and jammy. Set aside.
  2. Preheat oven to 350°F (175°C). Slice the entire slab of Hawaiian rolls in half horizontally. Place the bottom half in a 9x13 inch baking dish.
  3. Layer the provolone cheese slices on the bottom buns, followed by the roast beef and the caramelized onions. Top with remaining cheese and the top bun slab.
  4. Whisk melted butter and garlic powder together. Brush the mixture evenly over the tops of the rolls.
  5. Bake for 15–20 minutes, or until the cheese is bubbling and the tops are golden brown.
  6. While sliders bake, combine beef broth, Worcestershire sauce, garlic, and pepper in a small saucepan. Simmer over medium heat for 10 minutes to reduce until glossy.
