These Roast Beef Sliders are a delicious and easy-to-make appetizer or party snack featuring tender deli roast beef, caramelized onions, and melted provolone cheese layered on soft Hawaiian rolls. The buttery maple syrup glaze brushed on top adds a sweet and savory finish, baked until golden and topped with poppy seeds and fresh parsley for a flavorful bite-sized treat.

Ingredients

Caramelized Onions

  • 2 cups yellow onions, sliced
  • 1 tablespoon olive oil
  • 1 tablespoon unsalted butter
  • ⅛ teaspoon coarse kosher salt
  • ⅛ teaspoon black pepper

Sliders

  • 12 Hawaiian rolls or slider buns, sliced in half horizontally
  • 12 slices provolone cheese
  • 1 pound deli roast beef

Butter Glaze

  • 3 tablespoons unsalted butter, melted
  • 2 tablespoons maple syrup
  • 3 teaspoons Worcestershire sauce
  • 2 teaspoons spicy brown mustard
  • ¼ teaspoon garlic powder
  • 1 teaspoon poppy seeds

Garnish

  • 1 tablespoon fresh parsley, chopped (optional)

Instructions

  1. Preheat the Oven: Set your oven to 350°F (175°C) and line a 9x13 inch baking sheet with parchment paper to prepare for baking the sliders.
  2. Caramelize the Onions: In a skillet over medium heat, combine the sliced yellow onions, olive oil, 1 tablespoon butter, kosher salt, and black pepper. Cook, stirring occasionally until the onions become soft and slightly caramelized, about 10-15 minutes. Remove from heat and set aside.
  3. Assemble the Sliders - Bottom Layer: Place the bottom halves of the Hawaiian rolls on the prepared baking sheet. Layer six slices of provolone cheese evenly over the rolls, followed by the deli roast beef, then the caramelized onions. Finally, add the remaining six slices of provolone cheese on top of the onions.
  4. Add the Top Layer: Cover the layered fillings with the top halves of the rolls, forming complete sliders.
  5. Prepare and Apply Butter Glaze: In a small bowl, whisk together melted butter, maple syrup, Worcestershire sauce, spicy brown mustard, and garlic powder until fully combined. Brush this mixture generously over the tops of the slider buns.
  6. Bake the Sliders: Cover the baking sheet with aluminum foil and bake in the preheated oven for 15-20 minutes, or until the sliders are heated through and the cheese has melted.
  7. Add Final Touches: Remove the foil, sprinkle the poppy seeds evenly across the tops of the sliders, and if desired, garnish with chopped fresh parsley before serving.

Notes

  • For best results, use fresh deli roast beef thinly sliced for tenderness.
  • Caramelizing the onions slowly brings out their natural sweetness, balancing the savory flavors.
  • The Hawaiian rolls add a slightly sweet, soft texture perfect for sliders, but any soft slider bun can be substituted.
  • If you prefer spicier sliders, add a dash of hot sauce to the butter glaze.
  • These sliders are best served warm and fresh but can be reheated covered in the oven to maintain moisture.
