Ingredients
- 12 oz rotini pasta
- 1 lb ground beef or Italian sausage
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 1 bell pepper, chopped (any color)
- 1 can (15 oz) pizza sauce
- 1 can (14.5 oz) diced tomatoes, drained
- 1 teaspoon Italian seasoning
- 1/2 teaspoon red pepper flakes (optional)
- Salt and black pepper, to taste
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup sliced pepperoni, divided
- Cooking spray or a little oil, for greasing the baking dish
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or a little oil and set aside.
- Bring a large pot of salted water to a boil. Add the rotini pasta and cook according to package directions until al dente. Drain well and set aside.
- While the pasta cooks, place a large skillet over medium heat. Add the ground beef or Italian sausage and cook, breaking it apart with a spoon, until browned and cooked through.
- Stir in the chopped onion and minced garlic. Cook for 3–4 minutes, until the onion is softened and translucent and the garlic is fragrant.
- Add the chopped bell pepper, pizza sauce, drained diced tomatoes, Italian seasoning, red pepper flakes (if using), and a pinch of salt and pepper. Stir to combine and let the mixture simmer for about 5 minutes to blend the flavors.
- In a large mixing bowl, combine the cooked pasta with the meat and sauce mixture. Add 1 cup of the shredded mozzarella and half of the sliced pepperoni. Stir until everything is evenly coated and distributed.
- Transfer the pasta mixture to the prepared 9×13-inch baking dish, spreading it into an even layer.
- Sprinkle the remaining 1 cup of mozzarella cheese evenly over the top, then arrange the remaining pepperoni slices over the cheese.
- Bake for 25–30 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
- Remove from the oven and let the casserole rest for 5–10 minutes before serving so it sets slightly and is easier to scoop.
Variation
- Turn it into a supreme pizza casserole by adding sliced black olives, mushrooms, and extra bell peppers to the skillet with the veggies.
- Swap part of the mozzarella for provolone or an Italian cheese blend for a deeper, more complex cheesy flavor.
- Make a lighter version by using lean ground meat, part-skim mozzarella, and adding extra vegetables like spinach or zucchini to bulk it up.
Cooking Notes
- Cook the pasta just to al dente so it doesn’t become mushy after baking in the sauce.
- If the casserole looks a bit dry before baking, you can stir in an extra few tablespoons of pizza sauce or a splash of pasta water.
- If the cheese is browning too quickly in the oven, loosely tent the dish with foil for the last 5–10 minutes of baking.
Serving Suggestions
- Serve with a simple green salad or Caesar salad to balance the rich, cheesy casserole.
- Add garlic bread or breadsticks on the side to soak up any extra sauce and complete the “pizza night” vibe.
- Offer extra pizza toppings at the table red pepper flakes, grated Parmesan, and fresh basil or oregano for sprinkling.
Tips
- Prep ahead by assembling the casserole up to the baking step, then cover and refrigerate for up to 24 hours; add 5–10 minutes to the baking time if baking from cold.
- For easier cleanup, brown the meat and build the sauce in a deep, oven-safe skillet and bake directly in it if it’s large enough.
- Shred your own mozzarella from a block for the best melt and stretch pre-shredded cheese often contains anti-caking agents that affect texture.

Frequently Asked Questions
- Can I make Pizza Casserole ahead of time?
Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours. When ready to bake, let it sit at room temperature while the oven preheats and add 5–10 minutes to the baking time if needed. - Can I freeze Pizza Casserole?
Absolutely. Assemble and cool completely, then wrap well and freeze for up to 2–3 months. Thaw overnight in the refrigerator and bake until hot and bubbly. - Can I use a different type of pasta?
Yes. Any short, sturdy pasta like penne, ziti, or fusilli will work just cook to al dente so it holds up during baking. - How can I customize the toppings?
Treat it like your favorite pizza: add or swap toppings such as mushrooms, olives, spinach, cooked bacon, or extra pepperoni, keeping overall amounts similar so it still bakes evenly.

Notes
- Use Italian sausage for extra classic pizzeria flavor, or stick with ground beef for a milder, kid-friendly version.
- Rotini holds the sauce beautifully, but penne, fusilli, or ziti all work well in this casserole.
- Taste the sauce mixture before combining with the pasta and adjust the seasoning with additional salt, pepper, or red pepper flakes as desired.
- Letting the casserole rest after baking helps it thicken slightly and makes for neater slices and easier serving.
