How to store potatoes to keep them fresh longest?

Proper potato storage for extended freshness

Store potatoes in a cool, dark, well-ventilated place away from direct sunlight. Ideal temperatures are around 45–50°F (7–10°C). Refrigeration can convert potato starch to sugar, altering flavor and causing darkening during cooking, so avoid the fridge unless in very warm conditions.

Storage basics:

• Keep them in a breathable container: a paper bag, mesh bag, or basket.
• Avoid sealed plastic bags that trap moisture and encourage rot.
• Store away from onions—gases from onions can accelerate spoilage.

Preventing sprouting and greening:

• Check periodically and remove any sprouted or soft potatoes.
• If they turn green, cut away the green areas before cooking since they contain bitter compounds.

Long-term options: For extended storage, a root cellar or cool basement is ideal, or consider curing for a week in a slightly warmer spot to toughen skins before moving them to cool storage. With proper conditions, potatoes can keep several weeks to a few months depending on variety and freshness at purchase.
