Wrap the casserole twice with plastic wrap, and freeze. It will need to be defrosted overnight in the refrigerator before reheating.
To reheat for 15-20 minutes in a 350ºF, or until it reaches a minimum temperature of 170ºF. If desired, you can bake it for a few extra minutes under the broiler to get the cheese extra melty.
