What is chile relleno casserole?
In its traditional sense, classic chile relleno (Spanish for stuffed peppers) consists of whole green chilies that are stuffed with cheese and meat. Then, they are breaded, fried, and served with a sauce. Turning it into an easy chile rellenos casserole consists of stuffing the chiles with cheese but then creating an egg mixture that is poured over them and slow-cooked to perfection.
