Cooked casseroles
Line the pan with tinfoil and then fill the pan.  Whether you choose to cook ahead or put in raw, after it's prepared place the whole thing in the freezer and once it's frozen solid, pop the plastic wrapped food out of the pan, put it in a freezer bag and now you still have your pan to use in the meantime.  Write the baking instructions on the freezer bag.
