Step‑by‑Step Instructions for Cheesy Pizza Pasta Casserole
Step 1: Cook the Pasta
Start by bringing a large pot of salted water to a boil. Add the rotini pasta and cook it for about 7 minutes until it reaches an al dente texture. Ensure it is slightly firm to the bite, then drain it thoroughly in a colander, allowing any excess water to escape. Set the pasta aside while you prepare the other ingredients.
Step 2: Brown the Meat
In a large skillet over medium-high heat, add the ground beef and cook for 5-7 minutes, stirring occasionally until browned and no longer pink. Use a wooden spoon to break up the meat as it cooks. Once browned, drain any excess fat from the skillet, ensuring you keep the flavors intact.
Step 3: Season the Beef
With the ground beef cooked, sprinkle in the Italian seasoning, garlic powder, and kosher salt. Stir the mixture and cook for an additional 2 minutes, allowing the spices to infuse the meat with flavor. The beef should be fragrant and well-coated with the seasoning, making for a tasty base for your Cheesy Pizza Pasta Casserole.
Step 4: Add Vegetables
Next, add the diced onion and green bell pepper to the skillet with the seasoned beef. Sauté the mixture for about 3-4 minutes, stirring frequently, until the vegetables are softened and vibrant. The onions should become translucent, adding a natural sweetness to the dish.
Step 5: Stir in Marinara Sauce
Pour in the marinara sauce, stirring well to combine it with the beef and vegetable mixture. Let it simmer on low heat for about 5 minutes, allowing the flavors to meld together beautifully. You’ll know it’s ready when the sauce has heated through and started to bubble gently.
Step 6: Combine Pasta and Sauce
In a greased 9×13-inch baking dish, mix the cooked rotini pasta with the beef and sauce mixture. Give it a good stir to ensure the pasta is coated in the savory sauce. Then, fold in half of the shredded mozzarella cheese, which will add that creamy goodness to your Cheesy Pizza Pasta Casserole.
Step 7: Add Toppings
Sprinkle the remaining mozzarella cheese evenly over the top of the casserole, followed by a layer of pepperoni slices. Ensure the cheese is well-distributed, which will create that delicious cheesy crust as it bakes. The vibrant colors will brighten your dish, making it even more appetizing!
Step 8: Bake the Casserole
Preheat your oven to 375°F (190°C) and place the casserole in the oven. Bake for 20-25 minutes, or until the cheese is bubbling and has turned golden brown. Watch for that perfect, gooey texture, which signals that your Cheesy Pizza Pasta Casserole is ready to be enjoyed!

How to Store and Freeze Cheesy Pizza Pasta Casserole
Fridge: Store leftovers in an airtight container for up to 3 days. Reheat in the microwave or oven until warmed through, ensuring the cheese melts again for that comforting texture.
