Two classic comfort foods unite in this casserole: a creamy mac and cheese laced with an herby tomato sauce and topped with tons of gooey mozzarella cheese. Rounds of pepperoni finish things off with flair and just a hint of spice, and a seasoned breadcrumb topping adds a bit of texture.
You can easily vary this basic mac and cheese to feature your favorite pizza toppings. Olives, mushrooms, anchovies, peppers and more will dress it up and add even more flavor.
