How to Freeze a Sausage Casserole
Freezing your sausage casserole can make the difference between throwing away your leftovers and preserving the casserole for enjoying later. You can freeze just about anything, but you must take precautions before attempting to freeze a casserole.
If the dish is not properly covered, the casserole will become damaged by the cold and therefore inedible. Knowing how to freeze your casserole can help it retain its natural colour, texture and flavour for months.
Leave the sausage casserole on a cooling rack on your kitchen counter and wait until it cools completely. A hot or warm casserole will get freezer burn.
Cover the casserole dish. Place the whole sausage casserole into a zipper lock bag and then close the bag using your fingers. If the sausage casserole is too big for your largest plastic bag, cover the casserole with aluminium foil or cling wrap.
Put the casserole dish into the freeze on any shelf. Check it every week to see if the casserole dish is still properly sealed. You can freeze it for up to three months.
