Ingredients
Method
- Preheat your oven to 400°F (200°C). Grease a 9x13-inch baking dish with olive oil.
- Add the dry pasta directly to the dish. No boiling needed.
- Pour in sauces and liquid: Add pizza sauce, crushed tomatoes or marinara, and 2 cups of water or broth. Stir to coat the pasta evenly. You want the pasta just covered with liquid; add up to 1/2 cup more if needed.
- Season the base: Stir in Italian seasoning, garlic powder, a pinch of red pepper flakes if you like heat, and a light sprinkle of salt and black pepper.
- Add mix-ins: Fold in bell peppers, onions, mushrooms, olives, and cooked sausage if using. Scatter half the pepperoni through the mixture.
- Top with cheese: Sprinkle 1 1/2 to 2 cups mozzarella and the Parmesan over the top. Reserve some mozzarella (about 1/2 to 1 cup) for the final melt.
- Cover tightly with foil. Bake for 35–40 minutes, until the pasta is mostly tender and the liquid is bubbling.
- Uncover and finish: Remove the foil, add the remaining mozzarella, and arrange the rest of the pepperoni on top. Bake uncovered for 8–12 more minutes, until the cheese is melted and spotty-golden.
- Check doneness: The pasta should be al dente and the sauce thick and glossy. If it looks too loose, bake 5 more minutes. If too dry, splash in a little hot water and stir gently.
- Rest and serve: Let it sit for 5–10 minutes so the sauce sets. Finish with chopped basil or parsley and a crack of black pepper.
What Makes This Special
This casserole is all about zero-stress cooking with big flavor. The pasta cooks right in the sauce, so you save on dishes and time.
It’s endlessly customizable—think pepperoni, sausage, veggies, or even a fully loaded supreme. The texture lands somewhere between baked ziti and a deep-dish pizza, with a golden top and saucy, tender noodles underneath. It also reheats beautifully, making it great for meal prep or next-day lunches.

How to Make It
- Preheat your oven to 400°F (200°C).
Grease a 9×13-inch baking dish with olive oil.
- Add the dry pasta directly to the dish. No boiling needed.
- Pour in sauces and liquid: Add pizza sauce, crushed tomatoes or marinara, and 2 cups of water or broth. Stir to coat the pasta evenly.
You want the pasta just covered with liquid; add up to 1/2 cup more if needed.
- Season the base: Stir in Italian seasoning, garlic powder, a pinch of red pepper flakes if you like heat, and a light sprinkle of salt and black pepper.
- Add mix-ins: Fold in bell peppers, onions, mushrooms, olives, and cooked sausage if using. Scatter half the pepperoni through the mixture.
- Top with cheese: Sprinkle 1 1/2 to 2 cups mozzarella and the Parmesan over the top. Reserve some mozzarella (about 1/2 to 1 cup) for the final melt.
- Cover tightly with foil.
Bake for 35–40 minutes, until the pasta is mostly tender and the liquid is bubbling.
- Uncover and finish: Remove the foil, add the remaining mozzarella, and arrange the rest of the pepperoni on top. Bake uncovered for 8–12 more minutes, until the cheese is melted and spotty-golden.
- Check doneness: The pasta should be al dente and the sauce thick and glossy. If it looks too loose, bake 5 more minutes.
If too dry, splash in a little hot water and stir gently.
- Rest and serve: Let it sit for 5–10 minutes so the sauce sets. Finish with chopped basil or parsley and a crack of black pepper.
Storage Instructions
- Refrigerator: Cool completely, then cover or transfer to airtight containers. Keep up to 4 days.
- Freezer: Portion into freezer-safe containers and freeze for up to 3 months.
For best texture, freeze before adding the final top layer of cheese, then add it during reheating.
- Reheat: Microwave individual portions for 1–3 minutes, stirring halfway. Or reheat covered in a 350°F (175°C) oven for 15–20 minutes. Add a splash of water if it seems dry and top with fresh cheese to revive it.
Health Benefits
- Protein and calcium: Cheese and sausage (or a lean protein) add protein for fullness and calcium for bone health.
- Vegetable add-ins: Peppers, mushrooms, onions, and olives offer fiber, vitamins, and antioxidants.
Load them up to balance the richness.
- Whole-grain option: Using whole-wheat pasta boosts fiber and helps with steady energy.
- Customizable sodium: Choosing low-sodium sauces and broths helps manage salt intake without sacrificing flavor.
Pitfalls to Watch Out For
- Undercooked pasta: If you skimp on liquid or bake at too low a temperature, the pasta won’t soften. Make sure the noodles are just submerged before baking.
- Dry top layer: If the casserole is uncovered too early, the top can dry out. Keep it tightly covered for the first bake to steam the pasta.
- Too salty: Pepperoni, sausage, and cheese already carry salt.
Taste the sauce before adding more salt, and consider low-sodium broth.
- Watery sauce: Some mushrooms release a lot of moisture. Slice them thin and don’t overload the dish, or sauté them first if you prefer a thicker result.
- Grease pools: High-fat pepperoni and sausage can render excess oil. Use turkey versions or blot with paper towels before adding.
Variations You Can Try
- Supreme: Pepperoni, sausage, green peppers, onions, mushrooms, and black olives.
- Meat Lover’s: Sausage, pepperoni, and diced cooked bacon, with extra mozzarella.
- Veggie Delight: Zucchini, spinach, bell peppers, mushrooms, and onions.
Add ricotta dollops for creaminess.
- BBQ Chicken: Swap half the pizza sauce for BBQ sauce. Add cooked shredded chicken, red onion, and a little smoked gouda.
- Hawaiian: Diced ham and pineapple tidbits with mozzarella and a sprinkle of red pepper flakes.
- White Pizza Style: Use Alfredo or a garlic cream sauce with spinach, artichokes, and roasted garlic.
- Gluten-Free: Use a gluten-free short pasta and check that sauces and meats are certified gluten-free.
- High-Protein: Stir in cottage cheese or ricotta and use chickpea or lentil pasta.
FAQ
Can I use a different pasta shape?
Yes. Short, sturdy shapes like rotini, penne, ziti, and shells work best.
Avoid very small pasta like ditalini, which can overcook easily, and long pasta like spaghetti, which won’t bake evenly.
Do I have to cook the sausage first?
Yes, cook raw sausage before adding it. This ensures safe cooking and prevents excess grease from pooling in the dish.
How do I prevent the pasta from getting mushy?
Stick to the baking time, keep the dish covered during the first phase, and aim for al dente. Whole-wheat or legume-based pasta tends to hold up slightly better than very thin white pasta.
Can I make it ahead?
Absolutely.
Assemble up to a day in advance and refrigerate, but add 10–15 minutes to the covered bake time since it will be cold. For best texture, wait to add the final cheese layer until you’re ready to finish baking.
What if I only have marinara and no pizza sauce?
That’s fine. Use marinara and boost it with a teaspoon of Italian seasoning, a pinch of sugar, and a drizzle of olive oil.
A little garlic powder and oregano will bring it closer to pizza-sauce flavor.
Is it spicy?
Not by default. Add crushed red pepper flakes to taste or choose a spicy sausage for heat. Keep it mild for kids and pass hot sauce at the table.
Can I cook it in a Dutch oven?
Yes.
A 5- to 6-quart Dutch oven works great. Cover with the lid for the first part of baking, then remove the lid to brown the cheese.
How can I add more vegetables without watering it down?
Use roasted or sautéed veggies, or keep raw additions to 1 1/2 to 2 cups total. Cut them small, and avoid very watery options like tomatoes unless you reduce other liquid slightly.
What cheese blend works best?
Mozzarella for melt, Parmesan for bite, and a bit of provolone or fontina for extra richness.
Pre-shredded is convenient, but freshly shredded melts smoother.
Can I make it dairy-free?
Yes. Use a dairy-free mozzarella-style shreds and skip the Parmesan or replace it with a vegan alternative. Check that your sauce is dairy-free as well.
