1 pound penne, rigatoni, or other hollow noodle type pasta cooked al dente
Instructions
Preheat the oven to 375°F.
In a medium pot heat the olive oil on medium heat. Add the onion and stir, cooking until translucent, about 5-7 minutes. Add the flour and stir constantly until a dough is formed. Cook for a minute. Slowly pour in the milk while whisking continuously. Cook, stirring constantly, until there are no lumps of flour and the sauce has begun to thicken.
Add 1 1/2 cups of the cheese, the oregano, and pepperoni. Stir until the cheese has completely melted. Add in the pizza sauce and the cooked pasta.
Transfer the pasta to either a casserole dish or individual dishes (you can use oven safe coffee mugs to provide everyone with their own personal bowl.) Sprinkle with the remaining 1/2 cup of mozzarella.
Bake for approximately 7-10 minutes or until the cheese is melted and has started to brown.
