Ingredients
  

  • Cream cheese – 8 oz, softened
  • Eggs – 4 large
  • Shredded mozzarella cheese – 3 cups, divided
  • Grated Parmesan – 1/2 cup
  • Garlic powder – 1 teaspoon
  • Onion powder – 1/2 teaspoon
  • Italian seasoning – 1 teaspoon
  • Crushed red pepper flakes – optional, a pinch
  • Low-sugar marinara or pizza sauce – 1 to 1 1/4 cups (check labels)
  • Pepperoni slices – 5 to 6 oz
  • Olive oil – 1 tablespoon, for greasing
  • Optional add-ins – sliced black olives, chopped green bell pepper, mushrooms, cooked Italian sausage, fresh basil
  • Salt and black pepper – to taste

Method
 

  1. Preheat and prep the pan. Heat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil or line it with parchment for easy cleanup.
  2. Make the base. In a large bowl, beat the softened cream cheese until smooth. Whisk in the eggs until fully combined and silky.
  3. Add cheeses and seasoning. Stir in 2 cups of shredded mozzarella and the Parmesan. Add garlic powder, onion powder, Italian seasoning, and a pinch of salt and pepper. Mix well.
  4. Par-bake the crust layer. Spread the mixture evenly in the prepared dish. Bake for 12–15 minutes, until set and lightly golden around the edges.
  5. Layer the sauce. Remove from the oven. Spread the low-sugar marinara over the base in a thin, even layer. You want coverage without pooling—start with 1 cup and add a little more if needed.
  6. Add toppings. Sprinkle the remaining 1 cup of mozzarella over the sauce. Arrange pepperoni slices on top. Add any optional toppings (keep veggies minimal to avoid excess moisture).
  7. Bake to finish. Return to the oven and bake for 12–15 minutes, until the cheese is melted and bubbling and the pepperoni edges are crisp.
  8. Optional broil. For a browned top, broil for 1–2 minutes, watching closely so it doesn’t burn.
  9. Rest and serve. Let the casserole rest for 5–10 minutes to set. Slice into squares and garnish with fresh basil or extra red pepper flakes if you like heat.
