3. Step-by-Step Instructions for Making Pizza Casserole
Step 1: Preheat the Oven and Cook the Pasta
- Preheat your oven to 375°F (190°C).
- Cook the pasta according to package instructions until al dente, then drain and set aside.
Step 2: Brown the Sausage
- In a large skillet over medium heat, cook the Italian sausage until browned, breaking it into small pieces as it cooks.
- Add the diced bell peppers and sauté until they are softened. Stir in the garlic powder and Italian seasoning for extra flavor.
Step 3: Combine Ingredients
- In a large mixing bowl, combine the cooked pasta, browned sausage, marinara sauce, sliced olives, and half of the pepperoni slices.
- Stir to mix the ingredients well.
Step 4: Assemble the Casserole
- Spread half of the pasta mixture evenly in a greased 9×13-inch baking dish.
- Sprinkle half of the mozzarella and Parmesan cheese over the pasta layer.
- Add the remaining pasta mixture on top, spreading it out evenly. Sprinkle with the remaining mozzarella and Parmesan cheeses.
Step 5: Top with Pepperoni and Bake
- Arrange the remaining pepperoni slices on top of the casserole.
- Cover the casserole with foil and bake for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Step 6: Garnish and Serve

4. Tips for Perfect Pizza Casserole
Customize Your Toppings
This casserole is highly customizable. Add mushrooms, onions, or even chopped spinach for extra flavor and nutrition.
Make It Ahead
You can assemble the casserole up to a day in advance. Cover and refrigerate, then bake it when you’re ready. If baking from cold, add a few extra minutes to the baking time.
Use High-Quality Marinara Sauce
Since marinara sauce is a big part of the flavor, opt for a good-quality sauce or make your own for the best results.
Preventing a Soggy Casserole
Drain the pasta well, and avoid adding too many high-moisture toppings (like tomatoes or mushrooms) without cooking them first, as this can make the casserole watery.
