Ingredients

  • 1 pound pasta (rotini or penne): The foundation of our casserole. These shapes are perfect for trapping the sauce and cheese in their nooks and crannies.
  • 2 cups marinara sauce: Provides the rich, tomato base that gives this dish its classic "pizza" flavor. It binds all the ingredients together.
  • 2 cups shredded mozzarella cheese: Creates that signature gooey, stretchy cheese pull we all love. It's the essential top layer that makes this a true casserole.
  • 1 cup sliced pepperoni: Adds a salty, savory, and slightly spicy kick that defines the pizza experience. It's the star of the show.
  • 1 teaspoon Italian seasoning: A blend of herbs that gives the sauce a fragrant, authentic Italian flavor profile. It elevates the entire dish.
  • Salt and pepper to taste: Used to season the pasta water and the final dish, ensuring all the flavors are balanced and bright.

Instructions

  1. Boil: Cook the pasta in a large pot of salted water according to package directions until al dente. Drain well using a colander and return to the pot.
  2. Combine: In the pot with the cooked pasta, add the marinara sauce, half of the shredded mozzarella cheese, half of the sliced pepperoni, and the Italian seasoning. Use a large spoon to stir until everything is evenly coated.
  3. Assemble: Pour the pasta mixture into a 9x13 inch baking dish and spread it into an even layer. Sprinkle the remaining mozzarella cheese and the rest of the pepperoni slices over the top.
  4. Bake: Place the baking dish in a preheated oven at 375°F (190°C) and bake for 20-25 minutes, or until the cheese is completely melted and bubbly. Use an oven mitt to carefully remove the dish from the oven.
  5. Rest and Serve: Let the casserole sit for 5-10 minutes to set before serving. This makes it easier to cut and serve. Use a large serving spoon to scoop generous portions.

Pro Tips

  • Upgrade Your Sauce: Use a high-quality marinara sauce for a richer, more complex flavor. You can also add a pinch of red pepper flakes to the sauce for a spicy kick.
  • Don't Overcook the Pasta: Boil the pasta until it's just al dente. Since it will continue to cook in the oven, this prevents it from becoming mushy.
  • Pre-Shred Your Cheese: While pre-shredded cheese is convenient, shredding a block of whole milk mozzarella yourself will give you a better melt and a creamier texture.
  • Crispy Pepperoni Edges: For extra-crispy pepperoni, arrange the slices on top of the cheese so they're exposed to the direct oven heat.
  • Make-Ahead Magic: Assemble the entire casserole a day in advance, cover it tightly, and store it in the refrigerator. Just add 5-10 minutes to the baking time.

Serving Suggestions

  • Garlic Breadsticks: The classic partner for any pasta dish. Serve warm, buttery breadsticks for dipping into the sauce.
  • Simple Green Salad: Cut the richness of the casserole with a light, crisp green salad tossed in a vinaigrette.
  • Steamed Vegetables: A side of steamed broccoli or asparagus adds a healthy element and a vibrant contrast.
  • Extra Toppings: Set out bowls of chopped black olives, diced onions, or extra parmesan cheese for guests to customize their plates.
