History of Pizza Casserole

Pizza casserole is a modern American comfort food inspired by classic Italian pizza. Home cooks began combining pizza ingredients into casseroles during the 1960s and 1970s as a convenient way to feed large families. Instead of preparing individual pizza doughs, everything could be layered into one baking dish.

Today, pizza casseroles have become popular worldwide because they are easy to customize, freezer-friendly, and incredibly satisfying.
