This hearty pizza casserole recipe combines tender rotini or penne, seasoned ground beef or Italian sausage, rich pizza sauce, diced tomatoes, pepperoni, mozzarella, and Parmesan in one bubbling 9-by-13-inch dinner casserole. It makes 6–8 generous servings and takes about 15–20 minutes to prepare, 35–40 minutes to bake, and approximately 55–60 minutes from start to finish.
Every forkful delivers the comforting flavor of a loaded pepperoni pizza with the satisfying texture of baked pasta. The sauce clings to the noodles, the meat adds savory richness, and the reserved pepperoni on top becomes crisp around the edges while the mozzarella melts into a golden, bubbly blanket.

This is the kind of dinner that makes a busy evening feel warm and manageable. It uses familiar ingredients, fills a large baking dish, and brings together the best parts of pizza night and baked pasta without requiring homemade dough.
The casserole is hearty enough for a hungry family, yet flexible enough to suit different tastes. Ground beef gives it a classic savory flavor, while Italian sausage adds a more seasoned, herby bite.
The layered construction is especially delicious. Instead of leaving all the cheese on top, you add some between the pasta layers, creating pockets of melted mozzarella and Parmesan throughout the dish.

Ingredients You’ll Need
The ingredient list is straightforward, but each component contributes something important to the finished casserole. Choose rotini for its sauce-catching spirals or penne for a firm, tube-shaped bite.
- Pasta: Use 12 ounces of rotini or penne, cooked just shy of al dente so it stays pleasantly firm after baking.
- Meat: One pound of lean ground beef or Italian sausage provides the savory foundation.
- Vegetables: Diced yellow onion, green bell pepper, and garlic create sweetness, freshness, and aromatic depth.
- Sauce and tomatoes: Pizza sauce or marinara combines with drained diced tomatoes for a rich, spoonable coating.
- Pizza toppings: Six ounces of sliced pepperoni add smoky, salty flavor, especially when some are reserved for the top.
- Cheese: Mozzarella melts beautifully, while Parmesan adds a sharper, nutty finish.
- Seasoning: Italian seasoning, salt, and black pepper round out the sauce.
Have the baking dish, large skillet, pasta pot, colander, foil, and cheese ready before you begin. A little preparation keeps the cooking process orderly and helps the casserole reach the oven while the pasta and sauce are still warm.
How to Make It Step-by-Step
Step 1: Heat the oven to 375°F and lightly grease a 9-by-13-inch baking dish. Greasing the dish helps prevent the saucy pasta and melted cheese from sticking around the edges.
Step 2: Bring a pot of salted water to a boil and cook the rotini or penne until just shy of al dente, usually 1–2 minutes less than the package directions. Drain it thoroughly, but do not rinse it, because a little surface starch helps the sauce cling.
Step 3: While the pasta cooks, brown the ground beef or Italian sausage in a large skillet over medium-high heat. Break the meat into small crumbles as it cooks, then drain excess fat before continuing.
Step 4: Add the diced onion and green bell pepper to the browned meat. Cook for 4–5 minutes, stirring occasionally, until the vegetables begin to soften, then add the garlic and cook for about 30 seconds.
Step 5: Stir in the pizza sauce or marinara sauce, drained diced tomatoes, Italian seasoning, salt, black pepper, and about half of the sliced pepperoni. Let the mixture simmer for 5 minutes so the flavors combine and the sauce becomes hot.
Step 6: Add the drained pasta to the skillet and stir gently until every noodle is coated with the meat-and-sauce mixture. Work carefully so the pasta does not break or become overly compact.
Step 7: Spoon half of the pasta mixture into the prepared baking dish. Sprinkle half of the mozzarella and Parmesan over the first layer, creating a cheesy center that melts into the sauce.
Step 8: Add the remaining pasta mixture and spread it into an even layer. Finish with the remaining mozzarella, Parmesan, and pepperoni, placing the pepperoni where its edges can brown.
Step 9: Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and continue baking for 10–15 minutes, until the casserole is bubbling around the edges and lightly browned on top.
Step 10: Remove the casserole from the oven and let it rest for 5–10 minutes before serving. The brief rest allows the layers to settle while keeping the cheese warm and stretchy.
Pro Tips for the Best Pizza Casserole
The most important tip is to avoid fully cooking the pasta before baking. Since the noodles absorb sauce and continue cooking in the oven, stopping 1–2 minutes early helps prevent a soft or mushy texture.
Drain the diced tomatoes well. Excess liquid can make the casserole loose, while properly drained tomatoes add bright tomato flavor without watering down the sauce.
Reserve about half of the pepperoni for the top. Pepperoni placed over the cheese becomes lightly crisp and releases flavorful oil into the surface, giving the finished dish a stronger pizza character.
For an especially attractive presentation, let the casserole rest before cutting or scooping. The cheese will remain melted, but the sauce will not rush across the plate.

Easy Variations and Serving Ideas
Italian sausage is an easy swap for ground beef and brings extra seasoning without changing the method. If using sausage, taste the sauce before adding all the salt because sausage and pepperoni can both be salty.
You can also add sliced mushrooms, black olives, banana peppers, or red bell pepper. Add mushrooms and peppers with the onion, or stir olives and banana peppers into the sauce during the five-minute simmer.
For a more pizza-like cheese topping, use mozzarella alone or combine mozzarella with provolone. The recipe calls for 2 cups of shredded mozzarella divided between the layers and top, so keep the total cheese quantity consistent.
Serve generous squares or scoops with a crisp green salad, steamed vegetables, or warm garlic bread. For a breakfast-friendly casserole idea on another day, try this hash brown breakfast bake.
Storage and Reheating
Cool leftover casserole promptly, then cover the baking dish or transfer portions to airtight containers. Refrigerate and enjoy the leftovers reheated until hot throughout.
For individual portions, the microwave is convenient; cover loosely and heat in short intervals so the pasta warms evenly. For a larger portion, place it in an oven-safe dish, cover with foil, and warm until hot, removing the foil near the end if you want the cheese to regain some of its baked texture.
Because the casserole contains sauce, pasta, meat, and cheese, it is also a practical make-ahead dinner. Assemble it close to baking time for the best texture, and allow a little extra time if the dish is chilled before going into the oven.
If you are planning a breakfast or brunch spread alongside dinner-inspired comfort food, our biscuits and gravy bake is another filling casserole to save.
What to Serve with It
A simple salad with crisp lettuce and a bright vinaigrette balances the rich cheese and meat. Roasted broccoli, green beans, or a bowl of sliced vegetables also add freshness without competing with the pizza flavors.
Garlic bread is a natural companion because it can soak up any extra sauce left on the plate. If you want a playful sweet finish after dinner, consider an apple French toast pizza for a later breakfast or brunch menu.

- Meanwhile, brown the ground beef or Italian sausage in a large skillet over medium-high heat. Drain any excess fat.
- Add the diced onion and green bell pepper to the skillet and cook for 4–5 minutes, until softened. Add the minced garlic and cook for about 30 seconds.
- Stir in the pizza or marinara sauce, drained tomatoes, Italian seasoning, salt, black pepper, and about half of the pepperoni. Simmer the mixture for 5 minutes.
- Combine the cooked pasta with the meat-and-sauce mixture, stirring gently until the noodles are evenly coated.
- Transfer half of the pasta mixture to the prepared baking dish. Sprinkle it with half of the mozzarella and Parmesan, then add the remaining pasta mixture.
- Top the casserole with the remaining mozzarella, Parmesan, and pepperoni. Arrange the pepperoni over the cheese so its edges can crisp as it bakes.
- Cover the dish loosely with foil and bake for 20 minutes. Remove the foil and bake for another 10–15 minutes, until the casserole is bubbling and lightly browned.
- Let the casserole rest for 5–10 minutes before serving. This gives the sauce time to settle and makes the portions easier to scoop.
Notes
Final Thoughts
This hearty pizza casserole is a dependable dinner for nights when everyone wants something comforting, cheesy, and satisfying. The recipe keeps the familiar flavors of pizza while making them easy to serve from one bubbling baking dish.
