Can You Freeze Mushrooms?
6. Freezer Bags
Placing your flash-frozen mushrooms into a freezer bag before placing them in the freezer will give them further protection from harm. You should also place the bags into a sturdy container if you have one because this will help to prevent them from being squashed.
Any moisture in the bag will turn into ice crystals, and this can cause damage to your mushrooms. For this reason, you should make sure to extract as much air from the bags as possible before putting them in the freezer. This is especially the case with mushrooms because they have a very high water content.
