Whether you need to let mushrooms rest after picking depends on what you plan to do with them. If you're planning to eat them, it's best to store them in the fridge, where they will last between seven and 14 days. They should be stored in paper bags, as plastic bags can cause them to rot. If you're planning to dry your mushrooms, it's best to use a dehydrator or a fan. You can also let them air dry on a sieve, but they must be completely dry before storing, or they will get moldy.

What You'll Learn
Mushrooms should be kept dry
Mushrooms are made of 80 to 90 percent water and have a porous texture, meaning they can easily soak up water. Because of their high water content, mushrooms must be kept dry to stay firm and fresh. Moisture is the number one enemy when it comes to keeping mushrooms fresh.
To prevent spoilage, it is best to store mushrooms in a brown paper bag or paper towels for storage. Paper allows for airflow, preventing excess moisture from building up and causing sliminess or mold. The paper towel and paper bag method work well to rein in the moisture, which means the mushrooms don't get slimy. The mushrooms in the paper towel-lined paper bag fared slightly better than those in an unlined paper bag.
If you buy mushrooms pre-packaged, the packaging's perforation will let in air to dry out any moisture the mushrooms release, so simply put them in the fridge. If you don't use all the mushrooms at once, cover them back up with plastic wrap punched with a couple of holes. If you don't have a brown paper bag, wrap the mushrooms in a paper towel and place them in a bowl in the refrigerator. Like the bag, the paper towel will absorb moisture, helping the mushrooms stay fresh.
If you're planning to store mushrooms for the long term, drying or even freezing them is the way to go. Drying them is easy — clean, slice, and let them air dry for a few days. Once dried, these mushrooms can last from several months to over a year if stored right.

Paper bags are best for storage
Mushrooms are made of 80 to 90 percent water and have a porous texture, meaning they are highly susceptible to absorbing water and moisture. This is why it is recommended to avoid washing mushrooms before storing them, as doing so will shorten their shelf life. Moisture is the number-one enemy when it comes to keeping mushrooms fresh.
Paper bags are the best option for storing mushrooms. They allow for airflow, preventing excess moisture from building up and causing sliminess or mold. The paper bag method is a popular storage method, especially if you stock up on mushrooms when they are available at a good price in the market. Paper towels can also be used to wrap the mushrooms and place them in a bowl in the refrigerator. Like the bag, the paper towel will absorb moisture, helping the mushrooms stay fresh.
If you are using a plastic bag, it is important to note that plastic traps moisture, and mushrooms will end up sitting in a damp container or bag, which causes discoloration, mold, and slime. If you are using plastic wrap, it is recommended to poke a few holes in it to avoid trapping moisture.
For those who want to keep their mushrooms for more than a few days, drying them is a good option. Air drying is a straightforward method that can be done at home. Clean your mushrooms, removing dirt and debris, and slice them. Then, lay the mushrooms on a clean, dry surface, making sure they are spaced out enough to allow good airflow. You can also place them on a tray in a well-ventilated area, flipping them occasionally for even drying.

Plastic wrap should be avoided
Mushrooms are made of 80 to 90 percent water and have a porous texture, meaning they are highly absorbent. Because of their water content, mushrooms must be kept dry to remain firm and fresh. The goal of mushroom storage is to prevent them from releasing water and pulling moisture from the air. Moisture is the number-one enemy when it comes to keeping mushrooms fresh.
Instead of plastic wrap, mushrooms can be stored in a brown paper bag, which allows for airflow and prevents excess moisture from building up. Paper bags help to keep mushrooms dry and fresh for longer. If you don't have a brown paper bag, you can use a paper towel, which will also absorb moisture.
Another option is to store mushrooms in a net bag, such as the kind that onions are often packaged in. You can hang the bag from a hook or nail near a window so that the mushrooms can absorb vitamin D. Any unused mushrooms will dry out and can be reconstituted later.

Mushrooms can be frozen
To freeze mushrooms, start by trimming any woody parts from the stems. Cut larger mushrooms into uniform pieces, and keep smaller mushrooms whole. The next step is to cook the mushrooms by either sauteing or steaming them. To saute the mushrooms, use a small amount of neutral oil in a pan over medium heat. Cook until the mushrooms are fork-tender and the pan is mostly dry. The mushrooms will release moisture into the pan before the liquid evaporates. Allow to cool. To steam the mushrooms, start by soaking them in a bowl with a couple of cups of water and a teaspoon of lemon juice to prevent them from turning brown. Bring a pot of water to a boil, add the mushrooms to a steamer basket, and steam for 3 to 5 minutes until cooked. Strain and allow to cool.
Once the mushrooms have cooled completely, it's time to freeze them. Flash freezing is the way to go, as it makes it especially easy to use the frozen mushrooms a few at a time. Just spread the cooled mushrooms onto a parchment paper-lined cookie sheet and pop them into the freezer for about an hour, or until they feel hard and frozen. Then, pile all the mushrooms into freezer-safe bags or containers, remove as much air as possible, seal, and label. Frozen mushrooms can be stored in the freezer for up to nine months.
When you're ready to use frozen mushrooms, simply take them straight from the freezer and add them to your dish. You can also thaw them in the fridge overnight if you prefer, but adding them frozen is easier and works just as well.

Drying mushrooms is a good preservation method
Mushrooms are versatile vegetables that can be preserved in several ways, including canning, freezing, drying, and pickling. However, drying mushrooms is an excellent preservation method for various reasons.
Firstly, drying mushrooms is a straightforward and convenient process. You can dry mushrooms in a clean, food-grade dehydrator or even in your oven. By placing the mushrooms on drying trays or racks, you ensure good air circulation, which is crucial for effective drying. This accessibility makes drying a preferred preservation method, especially for those without access to freezers or canning equipment.
Secondly, dried mushrooms have an extended shelf life. Properly stored dried mushrooms can last from six to twelve months, which is significantly longer than fresh mushrooms. This longevity makes dried mushrooms a valuable addition to your pantry, ensuring you always have a flavorful ingredient on hand.
Additionally, drying mushrooms helps retain their nutritional value and flavor. When dried, the vitamins, minerals, and antioxidants present in mushrooms are preserved, making them a nutritious option even after being stored for extended periods. Moreover, dried mushrooms are known to have a concentrated flavor profile, adding a rich, earthy taste to your dishes.
Dried mushrooms are also incredibly versatile in cooking. They can be easily rehydrated by soaking them in water, and they absorb the flavors of the liquid used, making them perfect for stocks, sauces, and soups. Alternatively, you can use dried mushrooms as they are, adding them directly to recipes like risottos, stews, or pasta dishes for a burst of flavor and texture.
In conclusion, drying mushrooms is an excellent preservation method that offers convenience, extended shelf life, nutritional retention, and flavor enhancement. It transforms fresh mushrooms into a versatile ingredient that can elevate your culinary creations while ensuring you always have a tasty, nutritious vegetable option on hand.
