Equipment
Method
- Preheat oven to 350°F and grease a 9x13-inch baking dish.
- Heat olive oil in a large skillet over medium heat. Add sliced bell pepper and onion, cooking for 5 to 7 minutes while stirring occasionally until soft and lightly caramelized. Season with salt and pepper, then remove from heat.
- Slice the slider rolls in half horizontally, keeping each half intact. Place the bottom half in the prepared baking dish.
- Layer 4 slices of Provolone cheese over the bottom rolls, tearing to cover evenly. Add the roast beef in an even layer, then spread the cooked peppers and onions over the beef.
- Top with the remaining 4 slices of Provolone cheese. Place the top half of the rolls over the filling, pressing down gently.
- In a small bowl, whisk together melted butter, minced garlic, Italian seasoning, and onion powder. Brush generously over the tops of the rolls.
- Cover with aluminum foil and bake for 10 minutes. Remove foil and bake for another 5 to 10 minutes until tops are golden brown and cheese is melted.
- Let rest for 2 to 3 minutes, then slice between rolls and serve hot.
Notes
Storage: Refrigerate in an airtight container for up to 3 days. Reheat individual sliders wrapped in damp paper towel in microwave for 30-45 seconds, or reheat multiple sliders covered with foil in 300°F oven for 10-15 minutes. Make-Ahead: Assemble completely, cover, and refrigerate up to 4 hours before baking. Variations: Use white American cheese for traditional texture, add sautéed mushrooms, or substitute grilled chicken for beef. Add pickled jalapeños for spice.
