I recently discovered a way to freeze casseroles, pastas, and soups without the need for a pan. It saves your pans and space in your freezer.
Here are the directions for casseroles or pastas:
-Line baking dish (any size or shape) with aluminum foil
-Make recipe, and bake completely in the foil-lined dish
-Refrigerate until cool
-Place in freezer for a few hours
-Remove foil and casserole from pan and wrap completely with foil, then label and date
-When you want to re-heat, just unwrap and add to original-sized pan and bake at original temperature and time (no need to thaw)
-Put Zip-lock freezer bag in pan so it is standing up-right, add soup
-Freeze for a few hours
-Remove bag from pan; soup should remove easily and stay in the shape of the pan
-Label and freeze
-When you want to re-heat, remove from plastic and add to pan until thaw, then heat.
