These Italian roast beef sliders are packed with flavor and perfect for parties or a quick dinner. Topped with a buttery herb glaze and baked until golden, they're irresistible!
Preheat the oven to 350°F (175°C). Lightly coat a rectangular baking dish with nonstick spray.
In a small bowl, whisk together melted butter, Worcestershire sauce, Dijon mustard, Italian seasoning, granulated garlic, and onion powder. Set aside.
Slice the slider rolls horizontally without separating them. Place the bottom halves in the prepared baking dish.
Layer the rolls with Provolone cheese, roast beef, and diced pepperoncini. Top with the other half of the rolls.
Brush the tops of the rolls generously with the butter mixture and sprinkle with poppy seeds.
Bake uncovered for 12 to 15 minutes, or until the cheese is melted and tops are golden. Slice and serve warm.
Notes
These sliders are customizable—feel free to use your favorite cheese or sandwich fillings. Serve with a dipping sauce like au jus or horseradish mayo for extra flavor.
