Are mushrooms OK if not refrigerated?
Leaving your fresh mushrooms out on the counter is the worst option when it comes to keeping them fresh. Most mushrooms will only stay fresh for about a day at room temperature before they start to brown and turn slimy.
What is the best way to store fresh mushrooms?
Store mushrooms in their original packaging or in a porous paper bag for prolonged shelf-life. Some mushrooms may keep for up to one week in the refrigerator. Fresh mushrooms should never be frozen, but frozen sauted mushrooms will keep for up to one month.
Do mushrooms need to be stored cold?
They should be stored in your refrigerator, preferably set to a temperature of right around 32 degrees. When the temperature is lower you risk chill damage, and if it’s much above freezing your mushrooms may not be protected from decay.
