Preheat your oven and lightly grease your baking dish. I carefully slice the rolls in half horizontally, keeping them connected so they’re easier to layer. Place the bottom half into the dish, making sure it fits snugly.
I spread the marinara sauce evenly over the bottom layer of rolls. This creates a pizza-style base and keeps every bite flavorful. Don’t overdo it, or the sliders may turn soggy.
Next, I sprinkle half of the mozzarella cheese over the sauce. Then I add a generous layer of pepperoni slices, followed by the remaining cheese to lock everything together.
I gently place the top half of the rolls back on, pressing lightly so the layers stick. This step helps the sliders bake evenly and hold their shape.
In a small bowl, I mix melted butter with Italian seasoning, garlic powder, and Parmesan cheese. This mixture gives the sliders that irresistible golden crust.
I brush the butter mixture generously over the tops of the rolls. Then I cover the dish with foil and bake until the cheese is melted, removing the foil at the end for browning.
Once baked, I let the sliders rest for a couple of minutes. This helps the cheese set slightly and makes slicing easier before serving.
