Potatoes (Whole): Storage & Shelf Life

Whole raw potatoes last 1-2 months in a cool, dark, well-ventilated pantry spot — not the fridge, which can convert some of a potato's starch into sugar at a faster rate than intended, subtly changing flavor and how it browns when cooked.

A genuine safety note worth knowing: any green tinge developing under a potato's skin (from light exposure, which triggers chlorophyll production alongside a natural toxin called solanine) should be cut away and discarded rather than eaten — a real, if generally mild in small amounts, toxin concern distinct from ordinary spoilage.

Freezing raw potatoes isn't recommended, since their texture turns watery and grainy once frozen and thawed raw — cooked potatoes (mashed, or roasted) freeze considerably better than raw ones, since cooking has already broken down the starch structure that freezing otherwise disrupts unpredictably.

A paper bag or cardboard box, rather than plastic, allows the airflow potatoes need to avoid trapped moisture.

Storing potatoes away from onions specifically helps prevent the moisture and gas exchange that can accelerate spoilage in both.

A potato that's sprouted can still be used once the sprouts and any nearby soft, discolored flesh are removed.

Checking a bag periodically and removing any potato with soft, mushy spots prevents that one potato from affecting the rest of the batch.

A potato that's turned green under the skin, from light exposure rather than age, should have that green portion cut away entirely before cooking, since it carries a bitter, mildly toxic compound distinct from ordinary spoilage.

Potatoes stored in the fridge convert some of their starch to sugar faster than expected at that temperature, which is why a cool, dark pantry spot, not the fridge, is the standard recommendation for raw whole potatoes.

A potato that feels notably lighter than its size suggests has typically lost internal moisture and started to shrivel, even if the skin hasn't visibly wrinkled yet.
