Q What is the best way to store mushrooms?

You can find our recommendations for the best way to store mushrooms on our website.

We've included those recommendations here for your convenience.

The best way to store loose button mushrooms is to keep them in the refrigerator in a loosely closed paper bag wrapped in a damp cloth or laid out in a glass dish that is covered with a moist cloth. Whether you use a paper bag, a damp cloth, or a glass dish, it's worth avoiding all storage methods that leave the mushrooms stacked in one big clump. The less surface contact they have with one another the fresher they will stay. A great step to avoid clumping is to make a first layer of mushrooms inside your paper bag or on top of your damp cloth or glass dish, and then cover this mushroom layer with a paper towel. A second layer of mushrooms can then be placed on top of the paper towel. These storage methods will help preserve the mushrooms' moisture without causing them to become soggy and keep them fresh for several days. Once mushrooms have developed a slimy layer across their surface, they are not longer fully fresh.

Mushrooms that are purchased prepackaged can usually be stored in the refrigerator for 3-7 days. However, to maximize freshness, we recommend removal from the original container and storage according to one of the methods described above. Recent research has shown refrigerator storage to be especially important for preserving mushroom phytonutrients. In research studies on button mushrooms, loss of phytonutrients related to discoloration and hardening of mushrooms has been shown to occur over a 6-8 day period as storage temperatures get increased from 38F/3C (a common household refrigerator temperature) to 59F/15C (a temperature much closer to room temperature). These study findings are good reasons not to leave mushrooms sitting out on the countertop or even storing them temporarily in a cabinet.
