Pizza Macaroni and Cheese is a cheesy, comforting casserole that blends the rich taste of macaroni and cheese with pizza flavors. Topped with pepperoni, olives, bell peppers, and gooey cheese, it's sure to satisfy any crowd.
Cook the Pasta: Boil the elbow macaroni until al dente. Drain and set aside.
Preheat your oven to 375°F (190°C).
In a large bowl, combine the cooked pasta, mozzarella, cheddar, Parmesan, milk, diced tomatoes, pepperoni, olives, bell pepper, onion, garlic powder, Italian seasoning, salt, and pepper. Mix well.
Grease a 9x13-inch baking dish, pour in the mixture, and spread evenly. Cover with foil and bake for 25 minutes.
Remove foil and bake for another 10 minutes, until the cheese is bubbly and golden brown.
