Preparation
Follow these simple steps to create your Cheesy Beef Pizza Casserole:
1. PREHEAT THE OVEN
Set your oven to 375°F (190°C) and grease a 9×13-inch baking dish with non-stick spray.
2. COOK THE PASTA
Boil the pasta according to the package instructions until al dente. Drain and set aside.
3. SAUTÉ THE BEEF AND VEGETABLES
In a large skillet, heat a drizzle of olive oil over medium heat. Add the ground beef and cook until browned, breaking it up into crumbles. Add the diced onion and minced garlic, cooking until fragrant and the onion becomes translucent (about 3-4 minutes). If using, toss in the diced bell peppers and cook for another 2 minutes.
4. ADD THE SAUCE
Stir in the marinara or pizza sauce, Italian seasoning, and crushed red pepper flakes (if using). Simmer for 5 minutes to allow the flavors to meld together.
5. ASSEMBLE THE CASSEROLE
In the prepared baking dish, layer half of the cooked pasta, followed by half of the beef sauce. Sprinkle with half of the mozzarella and cheddar cheeses. Repeat the layers, ending with the remaining cheese.
6. ADD THE TOPPINGS
Top the casserole with mini pepperoni slices, Parmesan cheese, and black olives for a true pizza feel.
7. BAKE
Cover the casserole with foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
8. GARNISH AND SERVE
Sprinkle with freshly chopped basil before serving. Slice into squares and enjoy!
