Equipment

  • 8-inch square baking dish
  • Measuring cups
  • Measuring spoons
  • Spatula
  • Oven mitts

Ingredients
  

  • 2 cups shredded low-moisture mozzarella cheese
  • 3 ounces sliced pepperoni
  • ⅓ cup no-added-sugar pizza sauce
  • ¼ cup freshly grated Parmesan cheese
  • ½ teaspoon Italian seasoning
  • ¼ teaspoon garlic powder
  • ¼ teaspoon red pepper flakes optional
  • 1 teaspoon olive oil for greasing

Instructions
 

  • Preheat the oven to 375°F (190°C). Lightly grease an 8-inch square baking dish with olive oil.
    Spread the pizza sauce evenly across the bottom of the dish.
    Sprinkle 1 cup mozzarella over the sauce, then arrange half the pepperoni slices on top.
    Add the remaining mozzarella and pepperoni.
    Sprinkle with Parmesan, Italian seasoning, garlic powder, and optional red pepper flakes.
    Bake uncovered for 15–20 minutes, until the cheese is melted and the edges are lightly golden.
    For crispier pepperoni, broil for 1–2 minutes while watching closely.
    Let rest for 3–5 minutes before serving.
