Quick answer

Yes. Winter squash lasts 1–3 months in the fridge and 10–12 months in the freezer. After that, or sooner if stored badly, it spoils: watch for the signs below.

How to tell if winter squash is bad

Smell

Fermented, sour or musty odour.

Texture

Soft, mushy or leaking spots, or wrinkled skin with soft flesh.

Colour

Dark bruising that spreads, or browning inside.

Mould

White, grey or green fuzz — discard soft produce; cut firm produce generously.

Winter squash past the expiration date

Best-by and sell-by

FoodKeeper gives unopened winter squash 2–6 weeks in the pantry or 1–3 months in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Past the date

Winter squash past its best-by date is usually safe if stored well; check smell, look and taste before using.

How to keep winter squash fresh longer

Store unwashed; wash just before eating.
Keep ethylene producers (apples, bananas, avocados) away from produce that over-ripens.
Refrigerate once cut, in a covered container.
