Two American favorites combine to make the most glorious Pizza Macaroni and Cheese. Creamy, cheesy pasta topped with pizza sauce, pepperoni and more cheese. Customize it and use your favorite toppings.
Preheat oven to 375 degrees F. Bring a large pot of water to a boil. Add salt and cook pasta 2 minutes less than the package directions.
Meanwhile, make the cheese sauce. Heat a saucepan over medium heat. Add butter and melt. Sprinkle in flour and whisk until smooth. Cook for 2 minutes, until slightly browned. Add about 1/3 of the milk to the saucepan. Whisk until smooth. Once slighty thickened, add in another 1/3 of the milk. Whisk and thicken again. Repeat with the remaining milk and cook until slighty thickened. It should coat the back of a spoon. When you drag your finger on the coated spoon, it should take a couple seconds to come back together.
Remove the saucepan from the heat. Combine the mozzarella, cheddar and parmesan cheese in a bowl. Reserve 1 1/2 cups of the cheese. Add remaining cheese to the saucepan and whisk until smooth.
Add pasta to a 13 x 9 pan. Pour cheese sauce over the pasta and stir until well coated. Dollop the pizza sauce over the mac and cheese and smooth over the top. Sprinkle with remaining cheese then top with pepperoni.
