Mushrooms
Fresh mushrooms keep 3 to 7 days in the fridge. Best in a paper bag rather than plastic, or they quickly turn slimy.
Store them dry and breathable
Fresh mushrooms keep about three to seven days in the fridge. Exactly how long depends heavily on the packaging. The mushrooms' biggest enemy is moisture in a closed space: in a plastic tray with film they sweat, quickly turn slimy and grow mould. In a paper bag or loosely in a cloth, by contrast, they can breathe and stay firm much longer.
Mushrooms should not be soaked. To clean them, wiping with a brush or dry cloth is enough; only for heavy dirt rinse briefly and pat dry at once. Waterlogged mushrooms lose their bite and spoil faster. Placed in the crisper drawer of the fridge, they get the cool but not too cold environment they like.
With mushrooms, the condition often tells you more than the printed date. Fresh mushrooms are firm, dry and pale with a closed cap. If they turn soft, dark, slimy or the gills open wide and brown, they are past their point. Slightly brownish pressure marks can be cut away, but broadly discoloured or slimy mushrooms should go.
How do I spot bad mushrooms?
Spoiled mushrooms give themselves away by feel and look:
A slippery, sticky film on the cap is the clearest sign of spoilage.
Heavily browned, blotchy or mushy mushrooms with wide-open, dark gills are past it.
A sour, musty or unpleasantly strong smell instead of a mild, earthy scent means: discard.
Pick up a mushroom and feel the cap. Fresh mushrooms feel firm and dry, slightly velvety. If the surface is slippery, sticky or slimy, spoilage has begun — then the mushrooms no longer belong in the pan. A look under the cap helps too: pale, closed gills are good, dark and split ones a sign of age.
Shelf life at a glance
The packaging decides the window:
| State | Shelf life |
|---|---|
| Refrigerated, in paper | 5–7 days |
| Refrigerated, in plastic film | 2–3 days |
| Room temperature | about 1 day |
| Cooked, refrigerated | 1–2 days |
Store it right
This keeps mushrooms firm longest:
Paper, not plastic — mushrooms need to breathe; in film they turn slimy.
Do not soak — wipe dry; waterlogged mushrooms spoil faster.
Use the crisper — cool but not too cold is ideal.
Freeze only cooked — raw they go mushy; lightly sautéed they freeze well.
Common myths
A few myths surround mushrooms:
An old myth from the days before fridges — mushroom dishes stored properly chilled can safely be reheated once.
Better not — wiping is enough. Water makes them slimy and watery.
Not necessarily — small pressure marks can be cut away. Only slimy, dark or smelly mushrooms should go.
Mushrooms store well for stock: lightly sautéed and then frozen they keep their bite and aroma, unlike raw-frozen ones that go mushy. That way you always have a base ready for sauces, risotto or stir-fries. Dried mushrooms are another good way to keep them: stored airtight and dark they last many months and lend a deep flavour to soups and sauces when soaked.
