Start by slicing the top off your garlic head to expose the cloves. Drizzle with olive oil, wrap in foil, and roast at 400°F for about 40 minutes until golden and soft. Roasted garlic adds a sweet, savory depth to the butter topping.
Slice your soft dinner rolls in half lengthwise. Layer on marinara sauce, mozzarella, provolone, and pepperoni. Sprinkle a little parmesan on top and place the top halves of the rolls back. This creates the gooey, cheesy core of your sliders.
Mash the roasted garlic and mix with butter, sage, dried basil, oregano, parsley, chili flakes, and a pinch of parmesan. Spread this butter generously over the rolls, making sure it seeps into every nook and cranny.
Wrap the prepared rolls in foil and bake at 375°F for 15–20 minutes. The cheese will bubble, and the garlic butter will melt perfectly, giving the sliders a golden, flavorful crust.
