This creamed corn recipe with cream cheese will stay good in the fridge for up to 3 days. Reheat leftovers in a saucepan or in the microwave until warm. Although you can freeze this side dish in an airtight container for up to 3 months it does have dairy in it and that can sometimes separate when frozen and reheated. If you do decide to freeze it you will want to defrost in the fridge overnight and reheat until warmed through.
