Most fresh mushrooms last about 3–7 days in the fridge, and up to about 7–10 days if they’re very fresh, whole, and stored well.

Quick Scoop

  • Whole fresh mushrooms in the fridge: roughly 5–10 days, depending on freshness, variety, and storage.
  • Sliced raw mushrooms: usually 3–7 days, often closer to the lower end (1–4 days if handled poorly).
  • Cooked mushrooms: about 3–4 days in a sealed container in the fridge.
  • Best storage: keep them dry , unwashed, in a paper bag or breathable container on a fridge shelf (not in a sealed plastic bag).
  • When to throw them out: if they’re slimy, very dark and soggy, smell sour or like ammonia, or have fuzzy mold, it’s safest to bin them.

Tiny fridge story

Think of a box of mushrooms as that one friend who hates humidity: if you cram them in a sweaty plastic bag, they get slimy and sad fast; tuck them into a dry paper bag on a cool fridge shelf, and they stay firm and earthy for roughly a week, sometimes a bit longer if they were super fresh to begin with.

Mini sections

1. Typical time ranges

  • Whole, raw: 5–10 days in the fridge when stored properly.
  • Sliced, raw: 3–7 days; surface exposure makes them spoil faster.
  • Cooked: about 3–4 days with good chilling and clean handling.

2. Storage tips so they last longer

  • Keep them unwashed until right before cooking to avoid extra moisture.
  • Store in a paper bag or other breathable container, not tightly sealed plastic.
  • Use a main fridge shelf, not the warm fridge door; cool, steady temperatures help them last closer to the upper end of the range.

3. Safety first

If you’re near the end of those time windows, always check with your senses: if they look shriveled but dry, they’re often just less tasty; if they’re slimy, smelly, or moldy, don’t taste-test—just discard.
