There are some meals that just have a way of bringing a smile to everyone’s face, and this Pepperoni Pizza Casserole is one of them. It’s the perfect marriage of two comfort food classics—the familiar, savory flavor of a pepperoni pizza and the hearty, satisfying warmth of a pasta bake. With tender pasta, a rich pizza sauce, spicy pepperoni, and a generous layer of gooey cheese, this dish is a guaranteed crowd-pleaser.

I discovered this recipe on a mission to find a fun, easy dinner that would get everyone excited, and it was an instant hit. It’s a fantastic solution for a busy weeknight, but it feels special enough to serve on a weekend. The best part? It’s a one-pan wonder that makes cleanup a breeze.

Why I Love This Recipe

I love this recipe because it’s a perfect blend of nostalgic flavor and new, exciting texture. The pasta, sauce, and pepperoni all get mixed together, so every single bite is packed with that classic pizza taste. The Italian seasoning adds a wonderful herby flavor, and the two layers of cheese—mozzarella in the mix and a final sprinkle of Parmesan on top—create a cheesy, savory finish that is absolutely irresistible. It’s a fantastic make-ahead option, and it’s a great way to feed a crowd. It’s a simple, delicious, and deeply satisfying dish that is perfect for any occasion.

Ingredients

• 1 lb pasta (such as rotini or penne)
• 1 jar (about 24 ounces) pizza sauce
• 2 cups sliced pepperoni, divided
• 2 cups shredded mozzarella cheese, divided
• 1 teaspoon Italian seasoning
• 1/2 cup grated Parmesan cheese
• Salt and black pepper, to taste

Swaps and Notes

• Pasta: Rotini or penne pasta are perfect for this casserole because they hold the sauce and pepperoni pieces so well. You can use any short pasta shape you prefer.
• Sauce: A good quality store-bought pizza sauce is a great shortcut. You can also use your favorite homemade tomato sauce.
• Pepperoni: I’ve used classic pepperoni slices here, but you can also use a spicy variety for a little kick.
• Cheese: Mozzarella is essential for the classic pizza melt. Parmesan cheese on top adds a salty, nutty flavor and a beautiful golden crust. You can also add some provolone or a different cheese blend.
• Add-ins: Feel free to get creative! You could add some sautéed bell peppers, onions, or even some mushrooms to the mix for a more veggie-filled casserole.

How to Make Pepperoni Pizza Casserole

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Cook the Pasta: Cook the pasta in a large pot of lightly salted water according to the package directions. Drain it well.
3. Combine the Ingredients: In a large bowl, combine the cooked pasta, pizza sauce, 1 ½ cups of the sliced pepperoni, 1 ½ cups of the shredded mozzarella cheese, Italian seasoning, salt, and pepper. Mix everything together until the pasta is well-coated and the flavors are evenly distributed.
4. Assemble and Bake: Pour the mixture into a greased 9×13 inch baking dish, spreading it out evenly. Sprinkle the remaining 1/2 cup of mozzarella and the Parmesan cheese over the top. Arrange the remaining 1/2 cup of pepperoni slices on top.
5. Bake to Perfection: Bake for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown.
6. Rest and Serve: Let the casserole cool for a few minutes before serving. This allows it to set up and makes it much easier to scoop.

Tips for Success

• Cook Pasta Al Dente: Cook the pasta to al dente, as it will continue to cook in the oven. This prevents it from getting mushy.
• Don’t Overmix: When you combine the ingredients, mix until just combined. You don’t want to break up the pasta.
• Let it Rest: The resting time after baking is important. It allows the casserole to set up and makes it much easier to serve.

Serving Suggestions and Pairings

This pepperoni pizza casserole is a complete meal on its own, but it pairs wonderfully with a simple green salad or some garlic bread for dipping. For other great crowd-pleasing meals, you could serve it with a hearty Instant Pot Lasagna or my Classic Spaghetti Recipe with Homemade Sauce.

Storage and Leftover Tips

Leftovers are delicious! Store them in an airtight container in the refrigerator for up to 3 days. To reheat, you can microwave individual portions or warm the entire dish in the oven until heated through.
