I am not sure about cooked and/or mashed but you will need to do 'canning'. Here is a link for how to can peeled and cubed raw potatoes but you might want to check out a few other sites to be sure you understand 'safe canning' or you will risk getting food poisoning if not done and sealed correctly.

Hopefully someone else here at ThriftyFun can give you more tips and links on canning potatoes :-)

Oh, and here's another link that will give you a guideline of how long the shelf life is for properly processed home canned foods:


One other thing to keep in mind is that no cooked food is safe at ambient/room temperature for more than three to four hours. Even leaving out in a closed container for longer than that is risking food poisoning. Please refrigerate or freeze cooked foods, even potatoes, as soon as possible.
