Ingredients

Sliders

  • 2 tablespoons unsalted butter softened
  • 1 package Hawaiian sweet rolls 12 rolls
  • 1 pound deli roast beef
  • 12 slices provolone cheese

  • 1 packet au jus seasoning mix divided
  • 1 teaspoon Worcestershire sauce
  • 1 tablespoon toasted sesame seeds
  • ¾ teaspoon dried minced garlic
  • ½ teaspoon onion powder
  • ½ teaspoon seasoned salt optional

Instructions

  • Preheat oven to 350°F (175°C).
  • Butter the bottom of a 9×13-inch baking dish with softened butter.
  • Without separating the rolls, slice the entire package horizontally in half.
  • Place the bottom half into the baking dish.
  • Layer with 6 slices provolone cheese, roast beef, French fried onions (if using), remaining 6 slices of cheese, and top half of rolls.

Make the Topping

  • Melt butter in a small bowl. Stir in 1 tablespoon au jus seasoning mix, Worcestershire sauce, sesame seeds, dried garlic, onion powder, and seasoned salt. Whisk until combined.
  • Pour mixture evenly over the tops of the rolls, coating thoroughly.

Bake

  • Bake uncovered for 15–20 minutes, until cheese is melted and tops are golden brown.
  • Remove from oven and slice into individual sliders with a sharp knife.

Prepare Au Jus

  • In a small saucepan, combine remaining au jus seasoning mix with 2 cups cold water.
  • Bring to a boil, then reduce to a simmer until slightly thickened.
  • Serve warm alongside sliders for dipping.

Notes

  • Don’t Separate Rolls First: Keeps sliders intact and easier to assemble.
  • Use Quality Roast Beef: Thinly sliced deli beef works best.
  • Add Mushrooms or Caramelized Onions: For extra flavor.
  • Watch Closely While Baking: Tops should be golden, not overly browned.
  • Best Served Fresh: Enjoy while warm and melty.
