  • 1 tbsp olive oil
  • 2 large yellow onions thinly sliced
  • 1/2 tsp salt
  • 1/4 tsp black pepper
  • 1 lb deli-sliced roast beef thinly sliced
  • 6 slices provolone cheese cut in half
For the Au Jus
  • 3 cups beef broth low sodium
  • 2 tbsp Worcestershire sauce
  • 1 tsp onion powder
  • 1/2 tsp garlic powder
  • 1/4 tsp black pepper
  • Pinch red pepper flakes optional

Equipment

  • 9x13 inch baking dish
  • Large Skillet
  • Cutting Board
  • Sharp Knife
  • Small saucepan
  • Basting Brush

Method
 

Prepare the Caramelized Onions
  1. Heat olive oil in a large skillet over medium-low heat. Add the thinly sliced onions, salt, and pepper.
  2. Cook, stirring occasionally, for 15-20 minutes, or until the onions are deeply golden brown and very tender. Remove from heat and set aside.
Assemble the Sliders
  1. Preheat oven to 375°F (190°C).
  2. Slice the entire package of Hawaiian rolls horizontally, keeping the tops and bottoms intact. Place the bottom half of the rolls in a 9x13 inch baking dish.
  3. Evenly layer half of the provolone cheese slices over the bottom rolls.
  4. Distribute the caramelized onions over the cheese layer.
  5. Arrange the deli-sliced roast beef over the onions.
  6. Top the roast beef with the remaining half of the provolone cheese.
  7. Place the top half of the rolls back on, creating the slider tops.
  8. In a small bowl, combine the melted butter, garlic powder, and dried parsley flakes. Brush this mixture generously over the tops of the Hawaiian rolls.
Bake the Sliders
  1. Cover the baking dish loosely with aluminum foil.
  2. Bake for 10 minutes, then remove the foil and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly and the tops of the rolls are golden brown.
  3. Remove from oven and let rest for 5 minutes before slicing and serving.
Make the Au Jus
  1. While the sliders are baking, combine beef broth, Worcestershire sauce, onion powder, garlic powder, and black pepper (and optional red pepper flakes) in a small saucepan.
  2. Bring to a simmer over medium heat, then reduce heat to low and keep warm until ready to serve.

Notes

For a spicier kick, add a pinch of cayenne pepper to the butter topping. These sliders are best served immediately with the warm au jus on the side for dipping. Leftovers can be stored in an airtight container in the refrigerator for up to 2 days; reheat gently in the oven or microwave.
