What You'll Learn
Preparing shiitake mushrooms for dehydration
Next, you can choose to dehydrate the mushrooms in an oven or air dry them. If you opt for the oven method, preheat your oven to 175°F/80°C. Place the mushrooms on a baking rack over a sheet pan or an oven-proof plate. Leave them in the oven for about 2 hours, flipping them halfway through. After this, transfer the mushrooms to a colander to air-dry for another 3-5 days.
If you prefer to air dry the mushrooms without using an oven, place the cleaned and stemmed mushrooms in an open container with good airflow, such as a mesh colander. Leave them in a well-ventilated area, preferably with access to sunlight, for about a week. You can also take them outside to dry when it's not raining.
Once the mushrooms are completely dry to the touch and do not give when squeezed, they are ready for storage. Place them in an airtight glass container and store them in a cool, dry place. Properly dehydrated shiitake mushrooms can last for up to 1-2 years.

Air drying shiitake mushrooms
Air drying is the traditional method of drying shiitake mushrooms. It is a great way to dehydrate mushrooms without having to spend money on a dehydrator. The process is simple: place the mushrooms in an open container with good airflow underneath them (a mesh colander works great for this purpose) and leave them out to dry for about a week. They are ready to be stored when they are dry to the touch and do not give at all when squeezed.
However, there are some drawbacks to air drying. Firstly, it takes much longer than using a dehydrator or oven, and the time it takes is dependent on the environment. For example, a humid room is not suitable for air-drying mushrooms. Dry, desert-like places are better suited for this method. Additionally, air drying may not be very hygienic as particles can fall onto the mushrooms.
To expedite the air-drying process, you can partially dehydrate the mushrooms in the oven before leaving them to air-dry. Place the mushrooms in an oven heated to 175 degrees Fahrenheit or 80 degrees Celsius for 2 hours, flipping them halfway through. After this, the mushrooms will be partially dried. Transfer them to a colander to continue to air-dry for another 3-5 days.
Once fully dried, shiitake mushrooms will be very fragrant. They can be stored in a sealed container for up to a year, but it is important to ensure that they are completely dried before sealing. To rehydrate the mushrooms for cooking, soak them in warm water for 1-2 hours. The soaking liquid can also be used in cooking as it will be full of flavor.
Another option for air drying shiitake mushrooms is sun-drying. This method increases the vitamin D content of the mushrooms as the substance ergosterol in dried shiitake mushrooms is converted into vitamin D by ultraviolet rays. However, sun-drying has the disadvantage of being a slow process that uses low temperatures. Forest-grown shiitake mushrooms, in particular, can quickly decompose and lose their quality and taste if dried slowly. Therefore, it is recommended to dry them in the strong sunlight of midsummer, and for at least one hour if the ultraviolet rays are strong ("6" or above).

Oven-drying shiitake mushrooms
Drying mushrooms is a great way to extend their shelf life and preserve their flavour and nutritional value. Shiitake mushrooms, in particular, have an earthy flavour that can add depth to dishes like pasta sauces.
To dry shiitake mushrooms in an oven, first ensure that they are fresh and properly cleaned. Wipe your mushrooms with a damp paper towel, but do not put them in a bowl under running water as they are porous and can swell. Then, cut the mushrooms into thin strips or slices. Arrange the mushrooms on a lined baking sheet or an oven-proof plate in a single layer, ensuring that they are not overlapping as this can retain moisture. Place them in an oven preheated to between 125ºF and 175ºF (52ºC and 80ºC) for 2-3 hours. Flip the mushrooms over halfway through, and remove them once they are completely dry. To test if they are done, let them cool and then break a few pieces – they should be brittle and break, not bend.
Once fully dried, store your shiitake mushrooms in an airtight container in a cool, dry place. They will last for up to a year, maybe even longer, and can be used to add flavour to soups, sauces, and stir-fries.

Storing dried shiitake mushrooms
Dried shiitake mushrooms can be stored in a cool, dry place, preferably in a sealed, airtight container. Glass or plastic jars with tight-fitting lids are ideal, but plastic resealable bags can also be used. If you live in a humid climate, you can use oxygen-absorbing packets in your resealable bags or jars to keep the mushrooms from spoiling.
If you plan to store the mushrooms for more than six months, it is recommended to use a hard container and keep them in the freezer. However, if you prefer, you can store them at room temperature in a cabinet. Dried shiitake mushrooms can last for up to two years when properly stored.
It is important to note that dried mushrooms should be completely dried before sealing them in a container. If you are using a resealable plastic bag, squeeze out any excess air before sealing. Additionally, make sure to label the container and store the mushrooms in a cool, dry place, away from direct sunlight.
By following these storage guidelines, you can extend the shelf life of your dried shiitake mushrooms and maintain their quality and flavour.

Rehydrating dried shiitake mushrooms
Dried shiitake mushrooms are a staple in Asian cooking. The drying process intensifies the deep umami flavor of the mushrooms, allowing them to lend their strong flavor to stocks, soups, braises, and stir-fries. They can be rehydrated for use in cooking, but it's important to note that they will never return to the same consistency as fresh mushrooms.
To rehydrate dried shiitake mushrooms, start by gently rinsing them with cold water to remove any particles of dirt. Then, place the mushrooms in a bowl and cover them with warm water. The exact soaking time will depend on the thickness of the caps and your desired level of plumpness, but it typically ranges from 15 minutes to 2 hours. For the best flavor and texture, some recommend soaking the mushrooms in room temperature or cold water for at least 6 hours or even up to 24 hours.
During the soaking process, it is recommended to place a small plate, lid, or another item on top of the bowl to keep the mushrooms submerged. The soaking liquid is full of flavor and can be used in cooking as well, so be sure to save it!
Once the mushrooms are rehydrated, the stalks should be removed as they tend to remain woody and tough. The rehydrated mushrooms can then be cooked according to your recipe. They can also be frozen for later use, although it is recommended to freeze them uncut to allow for more flexibility in their use.
