Drying mushrooms is a great way to preserve them for later use. The drying process intensifies the flavour of the mushrooms, making them a perfect addition to stocks, soups, risottos, pasta dishes, and more. There are several ways to dry mushrooms, including using a dehydrator, an oven, or air-drying. While the use of special equipment like a dehydrator or an oven can speed up the drying process, it is not necessary. Air-drying mushrooms in a well-ventilated area for about a week can also effectively dry them.

Air drying mushrooms
Air-drying mushrooms is a simple process that requires no special equipment. It is important to note that the drying time will vary based on humidity levels and the size of the mushrooms.
Firstly, select fresh, locally-grown mushrooms that are free from any signs of decay, mould, or bruising. Clean the mushrooms using a brush or a damp cloth to wipe away any dirt. Try to avoid getting the mushrooms too wet, as this can cause mould to grow during the drying process.
Next, cut the mushrooms into slices. The thicker the mushrooms, the longer they will take to dry out, so it is recommended to slice them into pieces approximately 1/8 to 1/4-inch thick.
After cleaning and slicing the mushrooms, place them in a container that allows air to circulate around them. A mesh colander or a baking rack set on a baking sheet works well for this purpose. Ensure that the mushrooms are in a single layer and not overlapping, as this can cause them to fuse together while drying.
Place the container of mushrooms in a well-ventilated area with a supply of fresh air and preferably some sunlight. Allow the mushrooms to air-dry for 7-10 days, or until they are dry to the touch and do not give when squeezed. To expedite the process, you can partially dehydrate them in the oven for about an hour at 150-170°F (60-65°C) before transferring them to a windowsill to finish air-drying.
Once the mushrooms are completely dry, you can store them in airtight containers or bags. Store them in a cool, dry, and dark place, such as a pantry or refrigerator, where they will last for up to two years.

Using a dehydrator
Using an electric food dehydrator is an effective way to dry mushrooms fast while preserving their flavour and nutritional content. Dehydrators use a gentle heat source and constant airflow to gradually and evenly remove moisture from the mushrooms. This method allows for long-term storage and minimises the risk of contamination.
To dry mushrooms with a dehydrator, first, clean the mushrooms with a damp paper towel, mushroom brush, or by rinsing them under cold running water. Then, lay the mushrooms on a clean cloth or paper towel and gently blot them to remove surface moisture. This pre-drying step is important to reduce drying time and prevent mould growth.
Next, arrange the mushrooms on the dehydrator trays, ensuring they are spread out and not overlapping to allow for even drying. Set the dehydrator to a low temperature, ideally between 95°F and 120°F (some sources recommend 40°C or 130°F). The drying process can take anywhere from 4 to 12 hours, depending on the size and moisture content of the mushrooms. Check on your mushrooms every hour or so. They are ready when they are dry and brittle and snap easily instead of bending.
Once the mushrooms are dried, let them cool at room temperature to prevent condensation when storing. Then, transfer the mushrooms to airtight containers and store them in a cool, dark, and dry place to preserve their potency and extend their shelf life.

Drying in the oven
Drying mushrooms in the oven is a great way to preserve their flavour and intensify their taste. The process is simple and requires only an oven, baking sheets, and jars.
Firstly, ensure your mushrooms are clean and dry. It is a myth that mushrooms soak up lots of water, so be sure to wash them thoroughly under running cool water, scrubbing gently with a brush if necessary. Then, gently squeeze the mushrooms in a clean dish towel to remove any surface moisture.
Next, preheat your oven to a low temperature. Most sources recommend a temperature of around 150°F (65°C), but some suggest 130°F (54°C) or 125°F (52°C). Place the mushrooms on a baking sheet, ensuring they do not overlap, and put them in the oven for one hour.
After an hour, remove the mushrooms from the oven and turn them over. At this point, you can blot any moisture that has risen to the surface with a paper towel. Return the mushrooms to the oven for another hour.
Keep checking the mushrooms every half an hour, turning them over and blotting away any moisture until they are completely dry. A properly dehydrated mushroom should snap apart.
Once the mushrooms are dry, allow them to cool completely before transferring them to airtight glass jars for storage. Label the jars with the variety of mushroom and the date, and store them away from direct light or heat. Dried mushrooms can be stored for at least a year and can be rehydrated by soaking in boiling water for 20 to 30 minutes.

Preparing mushrooms for drying
The next step is to cut the mushrooms. Thicker mushrooms will take longer to dry, so it is recommended to slice them into pieces approximately 1/8 to 1/4 inch thick. Leave small mushrooms whole and unpeeled, while peeling and slicing larger mushrooms. After cutting, the mushrooms should be placed on a baking sheet or tray, ensuring they lay flat and side by side, with none overlapping. Do not oil the sheets, as this will alter the flavour and drying time.
At this stage, you can choose to partially dehydrate the mushrooms in an oven or dehydrator, or simply leave them to air-dry. If using an oven, preheat it to a low temperature, somewhere between 150-170°F (60-65°C). Place the mushrooms inside and leave for an hour, then flip them over and blot any moisture with a paper towel. Repeat this process until the mushrooms are completely dry, which may take up to 8-10 hours in a dehydrator and longer in a conventional oven. Alternatively, you can place the mushrooms in an open container with good airflow, such as a mesh colander, and leave them to air-dry for about a week.
Once the mushrooms are dry to the touch and feel like light rocks, they can be stored in airtight containers in a cool, dry, and dark place. Properly dried and stored mushrooms can last for several months, even years, and can be rehydrated for use in various dishes, adding a burst of flavour to your meals.

Storing dried mushrooms
The container should then be stored in a cool, dry, and dark place, such as a refrigerator or freezer. Heat and moisture are the biggest enemies of dried mushrooms, as they can cause the mushrooms to spoil faster and reduce their shelf life. Therefore, it is best to avoid storing them in warm cupboards or cabinets.
Properly stored dried mushrooms can last for up to two years or even longer, although their potency may gradually decline over time. It is a good idea to mark the date of storage to keep track of their shelf life and consume them before they begin to degrade naturally.
Additionally, it is recommended to open the containers every week or so for the first couple of months to change out the air and maintain freshness. This practice can help extend the shelf life of the dried mushrooms.
By following these simple storage guidelines, you can ensure that your dried mushrooms retain their quality, flavour, and potency for an extended period.

Clean the mushrooms and cut them into thin slices. Place them in an open container with good airflow, such as a mesh colander, and leave them in a well-ventilated area for about a week until they are completely dry.
The fastest way to dry mushrooms is to use a dehydrator or an oven, which can take around 8-10 hours or less. Air-drying mushrooms without any equipment will usually take about a week.
Once the mushrooms are completely dry, place them loosely in a large glass or plastic container. Store them in a cool, dry, and dark place, such as a pantry or refrigerator. Properly stored dried mushrooms can last for several months or even up to two years.
