Also known as veal mushroom, the oyster mushroom or oyster mushroom is one of the most popular edible mushrooms in Germany. It can be prepared in a variety of ways and is also great for freezing and drying. Properly stored, fresh oyster mushrooms will keep in the fridge for a short time.

Oyster mushrooms should be cleaned and stored unwashed in the refrigerator

Oyster mushrooms spoil quickly

Due to their very high protein content, oyster mushrooms - like all mushrooms - are perishable foods very quickly. They should be processed immediately after purchase or harvest and may not lie outside of a refrigeration system for longer than half a day. Otherwise they rot quickly and are then no longer edible - there is a risk of food poisoning. In addition, the collected goods must be cleaned immediately and then, if necessary, stored in the refrigerator until further use.

Store fresh mushrooms in the refrigerator

Fresh mushrooms and mushroom dishes have no place outside the refrigerator for storage. You should clean the fresh mushrooms as soon as possible and then either process them or store them in the vegetable compartment of the refrigerator for a day or two. In order for the sensitive mushroom protein to last longer and not decompose so quickly, it needs a dark, cool and, above all, dry storage room. Furthermore, the mushrooms must not be packed in plastic or aluminum containers, at best wrap them in a dry cotton or linen cloth. Moisture in particular leads to rapid deterioration and promotes mold growth.

Preserve oyster mushrooms

If the oyster mushrooms cannot be processed promptly, you should instead preserve them quickly by freezing or drying them. Here, too, the time factor is important: Only perfect, absolutely fresh mushrooms are suitable for this purpose, which should not have been stored in the refrigerator for a long time. For freezing, it is best to use a freezer that allows quick shock freezing to temperatures of at least minus 18 °C. In such conditions, frozen oyster mushrooms can be kept for up to six months. You can also freeze mushroom dishes that have already been prepared, as long as they are cooled down and shock frozen very quickly - preferably immediately after preparation.


Sometimes women's magazines recommend slicing the mushrooms and threading them onto twine to air dry. However, this is not a suitable method for drying mushrooms, because in this way they can spoil and mold very quickly.
