Philly cheesesteak sliders are a fun and delicious twist on a classic. Philly cheesesteaks are filled with thinly sliced steak, caramelized onions, crisp peppers, and, of course, melty cheese.
Preheat the oven to 375 degrees Fahrenheit. Cut 12 Hawaiian sweet rolls horizontally in half to have a top and bottom piece. Place the bottom half in a 13 x 9 x 2-inch baking dish.
Add 2 tablespoons olive oil, ½ medium onion sliced, 1 green bell pepper sliced to a large skillet over medium-high heat. Cook until tender, about 5 minutes. Remove from the skillet and set aside.
Returning to the same skillet, add 1 pound beef shaved steak,. Cook until no longer pink, about 5 minutes. The shaved beef will cook fast. Add t2 tablespoons Worcestershire sauce then season with salt and pepper, to taste.
Layer the cooked beef on top of the rolls in the pan.
Place the cooked onions and peppers on top of the meat.
Top with the 6 slices provolone cheese. Then, put on the top half of the buns.
Add 3 tablespoons butter to a small microwave-safe bowl and heat until melted. Mix in ¼ teaspoon garlic salt and 1 teaspoon dried onion flakes.
Brush the butter mixture on top of the buns using a basting brush.
Cover the baking dish with aluminum foil, then bake for 15 minutes. Remove the foil and bake for another 5 minutes, or until the cheese is melted and the tops of the buns are golden. Cut into individual sliders and serve warm!
