How to Make Pizza Pasta Casserole
Step 1: Preheat the Oven
Preheat your oven to 375℉. Spray a 9×13 baking dish with cooking spray and set it aside.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the rotini pasta according to the box directions until al dente, then drain it in a colander without rinsing.
Step 3: Cook the Beef
In a large skillet, cook and crumble the ground beef over medium-high heat, seasoning it with Italian seasoning, garlic powder, and kosher salt until no longer pink. Drain any excess grease.
Step 4: Combine Ingredients
In a large mixing bowl, combine the cooked pasta, beef mixture, chopped pepperoni (save 20 whole slices for the top), diced bell pepper, diced onion, marinara sauce, and 2 cups of mozzarella cheese. Stir until well combined.
Step 5: Bake the Casserole
Pour the pasta mixture into the prepared casserole pan and spread it evenly. Bake for 15 minutes. Remove from the oven and sprinkle 1 cup of mozzarella cheese over the top, followed by the reserved 20 whole pepperoni slices. Bake for an additional 10-15 minutes. Serve hot.
Pro Tips from My Kitchen
✓ Cook Pasta Perfectly – Make sure to cook the pasta al dente. It will continue cooking in the oven, preventing it from becoming mushy.
✓ Customize the Toppings – Feel free to toss in extra veggies like mushrooms or olives. It’s a great way to sneak in more nutrition without losing flavor.
✓ Use Fresh Seasonings – If you have fresh herbs on hand, like basil or oregano, add them for an extra burst of flavor. Fresh ingredients can elevate any dish.
✓ Don’t Rush the Meat – Take your time browning the ground beef. A good sear adds depth and richer flavor to the casserole.
✓ Leftover Magic – Store any leftovers in an airtight container in the fridge. This casserole tastes great the next day after the flavors have melded together.
