How to Make Pizza Pasta Casserole (Step-by-Step Instructions)
1. Cook the Pasta
Bring a large pot of salted water to a boil. Add rotini pasta and cook until just al dente (about 1 minute less than package instructions). Drain and set aside.
2. Brown the Beef
In a large skillet over medium-high heat, cook the ground beef until no longer pink, breaking it into small pieces with a wooden spoon. Drain excess fat if necessary.
3. Season the Meat
Stir in Italian seasoning, garlic powder, and kosher salt. Mix well so the beef absorbs the flavors.
4. Add the Veggies
Toss in the diced onion and green bell pepper. Cook for 3–4 minutes until softened and fragrant.
5. Combine with Sauce
Pour in the marinara sauce and stir everything together. Let it simmer on low heat for 5 minutes so the flavors blend.
6. Assemble the Casserole
In a greased 9×13-inch baking dish, layer the cooked pasta, beef-sauce mixture, and half of the shredded mozzarella. Stir to coat everything evenly. Top with the remaining cheese and arrange whole pepperoni slices on top.
7. Bake the Casserole
Preheat your oven to 375°F (190°C). Bake uncovered for 20–25 minutes, or until the cheese is melted, bubbly, and golden around the edges.
Serving and Decoration
- Garnish: Sprinkle with fresh parsley or basil before serving for color and freshness.
- Side Pairings: This casserole pairs well with garlic bread, a fresh green salad, or roasted vegetables.
- Kid-Friendly Tip: Let kids pick their own toppings like olives or mushrooms and add them before baking.

Storing Pizza Pasta Casserole
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Wrap tightly with foil or transfer to freezer-safe containers. Freeze up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Warm individual portions in the microwave, or reheat the whole casserole covered with foil at 350°F until hot.
Tips and Tricks for Success
- Cook Pasta Al Dente: Slightly undercooking prevents mushy pasta after baking.
- Drain Excess Fat: After browning beef, drain fat to keep the casserole from becoming greasy.
- Balance the Sauce: If your marinara is too acidic, stir in a teaspoon of sugar.
- Even Cheese Melt: Layer cheese in the middle and on top for gooey bites throughout.
- Make Ahead: Assemble the casserole, cover, and refrigerate up to 24 hours before baking.
