This pizza pasta bake is a quick, comforting dinner made with tender penne, rich marinara, gooey mozzarella, and plenty of pepperoni. It comes together with just four main ingredients, bakes in one casserole dish, and finishes under the broiler for golden cheese and crisp pepperoni edges.
When you want the familiar flavors of pizza without dealing with dough, this baked pasta is an especially practical option. The marinara coats every piece of penne, while mozzarella melts into a bubbling layer that holds the pepperoni in place.
The key is cooking the pasta slightly less than usual before it goes into the oven. That keeps the penne from becoming overly soft while it finishes cooking in the sauce. A brief broil at the end adds the browned, lightly crisp finish that makes the casserole particularly satisfying.
It is also a straightforward choice for weeknight dinners, casual gatherings, or any evening when you want something hearty without a long ingredient list.
Ingredients
Penne pasta: The sturdy tube shape holds plenty of marinara and stays pleasantly firm after baking. Cook it just short of al dente so it can finish in the oven.
Marinara sauce: Provides the tomato-rich base for the casserole and keeps the pasta moist as it bakes.
Pepperoni: Some is mixed directly into the sauced pasta so its savory flavor runs throughout the dish, while the rest goes on top where the edges can crisp.
Mozzarella cheese: Creates the melted, stretchy cheese layer across the casserole. Freshly shredding the mozzarella generally gives you smoother, more even melting.
Cooking Steps
STEP 1: Preheat your oven to 375°F and arrange a rack in the upper third. Keeping the casserole toward the top of the oven will be useful when you switch to broil for the final few minutes.
STEP 2: Bring a large pot of well-salted water to a full boil. Add the penne and cook it about 2 minutes less than the package recommends. You want the center to remain slightly firm because the pasta will continue absorbing sauce and softening while it bakes.
STEP 3: Drain the penne thoroughly and return it to the warm pot. Pour in the marinara sauce and add roughly one-third of the sliced pepperoni. Toss everything together until the pasta is evenly coated and the pepperoni is distributed throughout.
STEP 4: Spoon the pasta mixture into a 9 × 13-inch casserole dish. Spread it into a fairly even layer so the center and edges heat at a similar rate.
STEP 5: Cover the pasta evenly with the shredded mozzarella. Arrange the remaining pepperoni across the cheese, spreading the slices out rather than concentrating them in one area.
STEP 6: Bake the casserole uncovered for about 20 minutes. The sauce should be hot throughout and the mozzarella should be completely melted.
STEP 7: Switch the oven to broil and continue cooking for just a few minutes. Stay close to the oven during this stage because the cheese can go from lightly browned to overly dark quickly. Remove the casserole when the mozzarella has golden patches and the pepperoni edges look lightly crisp.
STEP 8: Let the finished casserole rest briefly before serving. A few minutes of standing gives the bubbling cheese and sauce time to settle, making the pasta easier to portion.
Can I assemble it ahead of time?
Yes. You can assemble the casserole in advance, cover it tightly, and refrigerate it until you are ready to bake. Because a chilled casserole starts at a lower temperature, it may need a little additional oven time. Make sure it is thoroughly hot in the center before serving.
Why should I undercook the pasta first?
The penne continues cooking after it is combined with marinara and placed in the oven. Cooking it about 2 minutes shy of the package directions helps prevent the finished pasta from becoming excessively soft.
It also leaves the pasta able to absorb some of the sauce during baking, which gives the casserole a more cohesive texture.
Can I skip the broiling step?
Absolutely. Broiling is mainly used to create golden spots on the mozzarella and slightly crisp the exposed pepperoni.
If the cheese is completely melted after the regular baking time, you can serve the casserole without broiling. The flavor will still be the same, although the surface will remain softer and less browned.
How do I know when the casserole is ready?
After about 20 minutes at 375°F, the sauce should be bubbling around some of the edges and the mozzarella should be completely melted.
Since the pasta has already been mostly cooked, you are primarily heating the ingredients together and allowing the flavors to combine rather than cooking the pasta from scratch.
Can I freeze the leftovers?
Yes. Cool the casserole first, then portion the leftovers into freezer-safe containers. Freezing individual servings can be especially convenient because you can reheat only what you need.
For the nicest texture, use frozen portions within about 2 to 3 months and thaw them in the refrigerator before reheating when possible.
Helpful Tips
- Keep the pasta firm. Resist the temptation to fully cook the penne during boiling. Slightly underdone pasta holds its shape much better after spending another 20 minutes in the oven.
- Shred the mozzarella shortly before using it. Freshly shredded cheese generally melts smoothly and gives the top of the casserole a more even finish.
- Watch closely while broiling. Broilers work quickly, especially with the casserole positioned in the upper third of the oven. Check frequently once the cheese begins developing golden spots.
Perfect Pairings
A simple green salad works especially well beside this rich casserole. Crisp greens provide a fresh contrast to the mozzarella, pepperoni, and tomato sauce without adding another heavy element to the meal.
Garlic bread is another natural pairing, particularly when you want something for scooping up the marinara left on the plate. A lightly toasted version keeps the meal from becoming too heavy.
For a vegetable side, try roasted broccoli. Its slightly browned edges and straightforward flavor complement both the tomato sauce and melted cheese while adding some variety to the plate.
Storage & Reheating
Allow leftovers to cool before transferring them to an airtight container. Refrigerated portions are best eaten within 3 to 4 days.
For longer storage, place individual portions in freezer-safe containers and freeze them for approximately 2 to 3 months. Thaw frozen pasta overnight in the refrigerator when you have time, particularly if you plan to reheat a larger portion.
To reheat several servings, transfer the pasta to an oven-safe dish, cover it to help retain moisture, and warm it in the oven until heated throughout. You can uncover it near the end if you want the mozzarella on top to become slightly browned again.
For a single serving, the microwave is usually the quickest choice. Heat it in shorter intervals until the sauce and pasta are hot all the way through. Avoid overheating it unnecessarily, since repeated or prolonged heating can make the pasta softer and cause the cheese to lose some of its pleasant texture.
Whether you are serving it immediately from the oven or warming up leftovers the next day, the combination of saucy penne, melted mozzarella, and crisp-edged pepperoni makes this four-ingredient casserole a dependable option for an uncomplicated, satisfying meal.
Pizza Pasta Bake
Ingredients
- 3 cups marinara sauce
- 10 oz sliced pepperoni
- 1 lb penne pasta
- 2 cups freshly shredded mozzarella cheese preferably grated just before use for smoother melting
Instructions
- Preheat the oven to 375°F. Arrange the oven rack within the upper third of the oven so the casserole can develop an evenly browned surface when it is broiled later.
- Bring a large pot of generously salted water to a full boil. Add the penne and cook it for 2 minutes less than the cooking time stated on the package. The pasta should remain slightly underdone because it will continue cooking in the oven.
- Drain the penne thoroughly, then place it back into the pot.
- Add the marinara sauce along with approximately one-third of the pepperoni slices. Stir until the pasta is evenly coated and the pepperoni is distributed throughout the mixture.
- Transfer the sauced pasta into a 9 × 13-inch baking or casserole dish. Spread the mixture into an even layer to promote consistent heating.
- Scatter the shredded mozzarella evenly across the entire surface of the pasta.
- Place the remaining pepperoni slices over the mozzarella, distributing them across the top.
- After the baking period, change the oven setting to broil. Broil for a few minutes, watching carefully, until the mozzarella develops light golden-brown areas and the pepperoni becomes slightly crisp around the edges.
- Carefully remove the finished pizza pasta bake from the oven. Allow it to stand for a few minutes before portioning and serving so the hot cheese and sauce can settle slightly.
