How to Make Baked Pizza Casserole
1. Preheat the Oven
Preheat your oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish.
2. Bring the Pasta Water to a Boil
Fill a large pot with water.
Add salt and bring it to a rolling boil.
3. Cook the Pasta
Add your chosen pasta.
Cook it approximately 1–2 minutes less than the package directions.
The pasta should be slightly firmer than al dente because it will continue cooking in the oven.
Drain and set aside.
Do not rinse.
4. Heat the Skillet
Place a large deep skillet over medium-high heat.
Add the olive oil.
5. Cook the Onion
Add the diced onion.
Cook for approximately 3–4 minutes, stirring occasionally, until softened.
6. Add the Garlic
Add the minced garlic.
Cook for approximately 30–60 seconds, just until fragrant.
7. Brown the Ground Beef
Add the ground beef.
Break it into small crumbles with a wooden spoon or spatula.
Cook for approximately 6–8 minutes, or until no pink remains.
Ground beef should reach 160°F (71°C).
Drain excess grease if necessary.
8. Add the Tomato Paste
Stir in the tomato paste.
Cook for approximately 1–2 minutes.
This helps deepen the tomato flavor.
9. Season the Beef
Add Italian seasoning, oregano, garlic powder, onion powder, smoked paprika, salt, black pepper, and red pepper flakes if using.
Stir until evenly combined.
10. Add the Sauce
Pour in the marinara or pizza sauce.
Add the drained diced tomatoes and Worcestershire sauce.
Stir well.
11. Simmer
Reduce the heat to medium-low.
Simmer the sauce for approximately 8–10 minutes.
The mixture should become slightly thicker.
12. Add Optional Vegetables
If using mushrooms, bell peppers, olives, or red onion, stir them into the sauce.
Cook for another 2–3 minutes.
13. Add the Pasta
Add the drained pasta to the skillet.
Fold gently until every piece is well coated with the meat sauce.
14. Add Some of the Cheese
Stir in:
- ½ cup mozzarella
- ½ cup cheddar
- ¼ cup Parmesan
Mix until evenly distributed.
This creates cheesy pockets throughout the casserole instead of keeping all the cheese on top.
15. Add Some Pepperoni
Chop or quarter about half of the pepperoni slices.
Fold them into the pasta mixture.
Reserve the remaining whole slices for the top.
16. Transfer to the Baking Dish
Spoon the pasta mixture into the prepared casserole dish.
Spread it evenly.
17. Add Mozzarella
Sprinkle the remaining mozzarella evenly over the top.
18. Add Cheddar
Add the remaining cheddar or Monterey Jack.
19. Add Parmesan
Sprinkle the remaining Parmesan over the cheese.
20. Add Pepperoni
Arrange the reserved pepperoni slices across the top just like you would on a pizza.
Add any additional toppings you want.
21. Bake
Place the casserole in the preheated oven.
Bake uncovered for approximately 20–25 minutes.
The sauce should be bubbling around the edges and the cheese should be completely melted.
22. Broil for Extra Browning
For a more pizza-like golden top, broil for approximately 1–2 minutes.
Watch continuously because pepperoni and cheese can brown quickly.
23. Rest
Remove the casserole from the oven.
Let it rest for approximately 5–10 minutes.
This helps the sauce settle and makes the casserole easier to serve.
24. Garnish and Serve
Sprinkle with fresh basil, parsley, Parmesan, and red pepper flakes if desired.
Serve hot.

Tips for the Best Baked Pizza Casserole
