How should I store potatoes? And how long can I keep them? If you purchased potatoes in a plastic bag, the best thing to do is to remove them from the plastic bag and put them in a paper bag, cardboard box or basket. Store them in an area that is dark, and cool, but not cold, such as a pantry, cupboard, or basement. Never store potatoes in the refrigerator; their cold temperature will turn the starch in potatoes to sugar, giving them an off-flavor. Potatoes will keep for 4-6 weeks in a cool, dark area. Even if they begin to grow sprouts and start to look shrivelled, they are still ok to eat.
