*This is the point where you can refrigerate or freeze the casserole if not serving right away. Wrap the dish, tightly, in plastic wrap & foil, then place in the fridge or freezer. Once you’re ready to bake the casserole, remove it from the fridge & let it come to room temperature on the counter for 30 minutes before baking. If frozen, thaw overnight in the fridge before baking. Remove the plastic wrap before baking.
