Chilling Cooked Potatoes
Many of us already knew about this. If you prepare too many potatoes – whether mashed or cubed – and know you won’t consume them within a few days, they should be frozen. It will not have an effect on the quality in any way, as long as you were concerned about that.

Potatoes are still as delicious when defrosted after a year in the freezer, and they have no flavor or texture changes. If you don’t have to use your potatoes right away, keep them frozen for up to a year. If possible, avoid using your potatoes in the microwave since this may impact their texture considerably.
