Potatoes need airflow to prevent the accumulation of moisture, which can lead to spoilage. The best way to allow free circulation of air is to store them in an open bowl or paper bag. Do not store them in a sealed container without ventilation, such as a zipped plastic bag or lidded glassware.
How do you store potatoes so they don't go bad?
The solution is to store them in a cool, dry, dark place. Cool as in not near the stove or heating vents (but not in the refrigerator). Dry and dark as in a cupboard or pantry that's not near the sink and is frequented enough where they won't be forgotten. A ventilated and dry basement is also a good option.
How do you store potatoes and how long do they last?
To store, keep them loosely covered in a paper bag, mesh bag, or cardboard box to provide good air circulation. At room temperature, potatoes will last up to two weeks.
