Ingredients
Sliders
- Cooking spray
- 1 package (12-count) Hawaiian sweet dinner rolls
- 1/3 cup mayonnaise
- 1 tablespoon olive oil
- 1/2 large yellow onion, thinly sliced (about 1 cup)
- 1 large green bell pepper, thinly sliced (about 1 cup)
- 3/4 pound deli roast beef (or up to 1 pound)
- 12 slices provolone cheese
Butter Topping
- 7 tablespoons unsalted butter
- 1-1/2 teaspoons dried minced onion
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1/2 teaspoon dried thyme
- 1/4 teaspoon salt
- 1/4 teaspoon pepper
Instructions
- Prepare the Pan and Oven: Generously grease a 9×13-inch baking pan with cooking spray. Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for baking the sliders.
- Sauté the Vegetables: Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once the oil is hot, add the sliced green bell pepper and yellow onion. Sauté these, stirring occasionally, until they become tender and slightly charred, which usually takes about 8 to 10 minutes. Remove from heat and set aside to cool.
- Assemble the Sliders: Slice the slab of Hawaiian rolls horizontally, keeping the individual rolls connected. Spread mayonnaise evenly over the inside surfaces of both the bottom and top halves. Place the bottom half of the rolls in the greased baking pan. Layer 6 slices of provolone cheese evenly on the bottom rolls, then spread the sliced roast beef on top. Add the sautéed peppers and onions over the beef, followed by the remaining 6 slices of provolone cheese.
- Initial Bake: Bake the assembled bottom portion of the sliders (without the top half) in the preheated oven for 10 minutes to allow the cheese to melt thoroughly.
- Prepare the Butter Topping: While the sliders bake, combine 7 tablespoons unsalted butter, 1-1/2 teaspoons dried minced onion, 1 tablespoon Worcestershire sauce, 1 teaspoon garlic powder, 1/2 teaspoon dried thyme, 1/4 teaspoon salt, and 1/4 teaspoon pepper in a bowl. Whisk this mixture until smooth and well blended.
- Add the Top and Butter: Remove the pan from the oven and carefully place the top half of the rolls onto the melted cheese. Pour and brush the prepared butter mixture generously over the tops and sides of the rolls, making sure to cover all exposed bread surfaces except the bottom.
- Final Bake Covered: Cover the baking pan tightly with aluminum foil and bake for an additional 20 minutes to allow flavors to meld and the bread to absorb the buttery goodness.
- Final Bake Uncovered: Remove the foil and bake for another 5 to 10 minutes, or until the tops are golden brown and crisp, and the cheese is fully melted and gooey.
- Serve and Enjoy: Once baked to perfection, cut the sliders apart while still hot and serve immediately. These cheesesteak sliders are best enjoyed fresh and warm.
Notes
- For a more tender roast beef, choose thinly sliced deli-style roast beef but you can also use leftover cooked steak cut thinly.
- Feel free to customize with different cheeses like mozzarella or American if preferred.
- If you don’t have dried minced onion, finely chopped fresh onion can be used in the butter mixture.
- Using Hawaiian rolls gives these sliders a sweet contrast but any soft dinner rolls will work.
- Leftovers can be reheated covered with foil in a 350°F oven for 10-15 minutes to restore freshness.
