Cooking Easy Pizza Casserole: The Process

Now, let’s get into the nitty-gritty of making this delicious Easy Pizza Casserole!
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a boil. Add the tortini or fusilli pasta and cook according to package instructions until al dente. Drain and set aside.
Step 2: Brown the Sausage
In a large skillet over medium heat, add the mild Italian sausage. Use a wooden spoon to break it into chunks as it cooks. Sauté until the sausage is browned and cooked through, about 5-7 minutes.
Step 3: Combine the Sauces
Once the sausage is cooked, reduce the heat to low and pour in the marinara or Pomodoro sauce and pizza sauce. Stir to combine and let it simmer for a few minutes to meld the flavors.
Step 4: Mix in the Pasta
Add the cooked pasta to the skillet with the sausage and sauce mixture. Stir well until the pasta is fully coated with the sauce.
Step 5: Layer the Ingredients
Preheat your oven to 350°F (175°C). In a greased casserole dish, layer half of the pasta mixture. Top this layer with half of the pepperoni slices, half of the grated Parmesan cheese, and half of the shredded mozzarella cheese.
Step 6: Add More Layers
Repeat the layering process with the remaining pasta mixture, pepperoni, Parmesan cheese, and mozzarella cheese.
Step 7: Bake to Perfection
Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
Step 8: Serve and Enjoy
Once baked, remove from the oven and let it cool for a few minutes. Serve warm and enjoy the delightful flavors of your Easy Pizza Casserole!
Substitutions by Category

If you’re missing an ingredient or two, here are some easy substitutions:
- Meat: Swap the mild Italian sausage for turkey sausage or ground chicken for a lighter option.
- Pasta: You can use any pasta shape you have on hand, such as penne or macaroni.
- Cheese: Feel free to use a blend of cheeses like cheddar or provolone for a different flavor.
- Sauces: Use homemade marinara or your favorite store-bought brands based on your preference.
Pro Tips & Notes
- For an extra crispy top, broil the casserole for a couple of minutes after baking, but keep an eye on it to prevent burning.
- Feel free to add vegetables like bell peppers, mushrooms, or olives for added flavor and nutrition.
- If you want a spicier kick, add some crushed red pepper flakes to the sausage while it cooks.
- This casserole is great for meal prep. It can be easily reheated and still tastes delicious!
Storing, Freezing & Reheating
To store leftovers, let the Easy Pizza Casserole cool completely, then cover it tightly with plastic wrap or foil. It will keep in the refrigerator for up to 3-4 days. For longer storage, you can freeze the casserole before or after baking. To freeze, wrap it tightly with aluminum foil or place it in an airtight container. It can be frozen for up to 3 months.
When you’re ready to reheat, thaw it in the refrigerator overnight if frozen. Bake in the oven at 350°F (175°C) until heated through, about 20-30 minutes. If reheating from frozen, you may need to increase the baking time.
Troubleshooting Q&A
What if my casserole turns out too dry?
If your casserole seems dry, it may need more sauce. Next time, consider adding a bit more marinara or pizza sauce to the mixture or serving with extra sauce on the side.
Can I make this ahead of time?
Absolutely! You can prepare the casserole in advance and store it in the refrigerator until you’re ready to bake. Just be sure to adjust the baking time since it will be cold from the fridge.
How do I know when the casserole is done?
The casserole is done when the cheese is melted and bubbly, and the edges are slightly golden brown. A food thermometer should read at least 165°F (74°C) in the center.
Can I customize the toppings?
Yes! This Easy Pizza Casserole is highly customizable. Feel free to add your favorite pizza toppings, such as olives, green peppers, or even different types of cheese.
