Drying porcini mushrooms is an effective way to preserve their flavour and extend their shelf life. There are several methods to dry porcini mushrooms, including sun drying, air drying, oven drying, and using a food dehydrator. The process involves cleaning the mushrooms, slicing them thinly, and then drying them until they are completely dry. Once dried, they can be stored in airtight containers and will last for several years. Properly dried porcini mushrooms can be easily rehydrated and used in various dishes, adding a new dimension of flavour to your cooking.

Using a food dehydrator
Drying porcini mushrooms is an excellent way to preserve their flavour and extend their shelf life. Using a food dehydrator is a simple and effective way to dry porcini mushrooms. Here is a step-by-step guide on how to do it:
Clean the Mushrooms
Before drying porcini mushrooms, it is essential to clean them thoroughly to remove any dirt or debris that may affect their flavour and shelf life. Use a dry paper towel or a damp cloth to gently wipe the mushrooms clean. Alternatively, you can use a vegetable brush, a mushroom brush, or a small toothbrush to brush off any dirt. If your mushrooms are very dirty, you can rinse them quickly under cold water, but make sure to pat them dry with a clean towel afterwards.
Prepare the Mushrooms
Cut the cleaned mushrooms into thin slices or small pieces. The thickness of the slices will determine the drying time, with thicker slices taking longer to dry. Depending on the size of your dehydrator trays, cut the mushrooms into pieces that are between 1/4 to 1/2 inch thick.
Arrange the Mushrooms on the Dehydrator Trays
Spread the sliced mushrooms on the dehydrator trays, making sure that none of the pieces are overlapping or touching. This allows for better airflow and even drying. Arrange the mushrooms close together to maximise the batch size, but ensure proper spacing for airflow.
Set the Dehydrator Temperature and Timing
Set the temperature on your dehydrator to between 110°F to 125°F (43°C to 52°C). The drying time will depend on the thickness of the slices and the specific model of your dehydrator, but it typically takes around 6 to 8 hours for 1/4-inch slices to dry completely. Check your mushrooms after 6 hours to gauge their dryness.
Allow the Mushrooms to Cool
Once the mushrooms are crispy and dry, remove the trays from the dehydrator and let the mushrooms cool down to room temperature. This ensures that the drying process is complete and prevents any residual heat from affecting the storage process.
Store the Dried Mushrooms
Transfer the cooled mushrooms to sanitized glass jars with tight-fitting lids. Label the jars with the type of mushroom and the date of drying. Store the jars in a cool, dry place, away from direct light and heat, to extend the shelf life of your dried porcini mushrooms.

Sun drying
To sun-dry porcini mushrooms, first, make sure your mushrooms are clean. Use a damp cloth or soft brush to remove any dirt or soil residue, then lightly rinse them with water and trim the ends. You can also use a dry paper towel to gently brush off any dirt or debris from the mushroom caps and stems. Removing the skin is optional but a good idea for older mushrooms.
Next, cut the mushrooms into thin slices, about a quarter-inch thick. Place the slices on a wire mesh or bamboo mat in a well-ventilated, dry area that receives plenty of sunlight. Make sure the mushrooms are spread out and not touching each other to ensure proper air circulation.
Turn the mushrooms occasionally to ensure even drying. The mushrooms are ready when they feel dry and leathery. Once the mushrooms are completely dry, bring them inside and allow them to cool to room temperature.
Finally, store the dried mushrooms in an airtight container such as Tupperware or a mason jar. Keep them in a cool, dark place, and they will last for several years.

Air drying
After cleaning, cut the mushrooms into thin slices or small pieces. The slices should be relatively thin, no more than a quarter of an inch thick. Place the sliced mushrooms on a wire mesh or bamboo mat in a well-ventilated, dry area. Ensure that the mushrooms are spread out and not touching each other to allow for proper air circulation.
Leave the mushrooms to dry for two to three days. During this time, larvae and worms will evacuate the mushrooms, and you can brush them off. Finish drying the mushrooms in a food dehydrator or in an oven at a low temperature (around 40°C or 105°F) for a few hours.
Once the mushrooms are completely dry, allow them to cool to room temperature before storing. Place the dried mushrooms in an airtight container and store them in a dark, cool place. Properly dried and stored porcini mushrooms will last for several years and can be easily rehydrated for use in various dishes.

Drying in the oven
Drying porcini mushrooms in the oven is a quick and easy method. It takes approximately 6 to 8 hours, depending on the thickness of the mushrooms.
First, clean the mushrooms and pat them completely dry. They should not be moist under any circumstances. Then, cut the porcini mushrooms into thin slices, no more than a quarter-inch thick. Arrange the slices in a single layer on a baking tray lined with parchment paper, ensuring the slices do not touch each other. Set your oven temperature to 105°F (40°C) and leave the door slightly ajar to allow moisture to escape.
The drying time will depend on the thickness of the slices and the number of racks in your oven. Check the mushrooms after 6 hours to see how they are drying. If they feel leathery and dry, they are done. If they are still moist, continue drying for another hour or so, checking periodically.
Once the mushrooms are completely dry, remove them from the oven and allow them to cool to room temperature. Then, store them in an airtight container and keep them in a dark and cool place. Properly dried and stored porcini mushrooms will last for several years.

Storing dried porcini mushrooms
Once dried, porcini mushrooms can be stored for months and can be easily rehydrated for use in soups, stews, pasta dishes, and risotto. Here are some tips for storing dried porcini mushrooms:
- Use an airtight container: Choose an airtight container such as a plastic resealable bag, a canning jar with a lid, or a glass container with a tight-fitting lid. Screw the lid tightly on the jar or seal the plastic bag completely to remove all air.
- Keep out of direct light: Store the container in a cool, dark, and dry place, such as a cabinet or the back of a kitchen cabinet. Avoid storing dried porcini mushrooms in direct light or a humid environment as this can affect their flavour and shelf life.
- Consider oxygen-absorbing packets: If you live in a humid climate, consider using oxygen-absorbing packets in your resealable bags or jars. These packets contain iron powder that absorbs oxygen, helping to keep the mushrooms from spoiling.
- Store in the fridge or freezer: For maximum shelf life, consider storing dried porcini mushrooms in the fridge or freezer. This helps to prevent heat and moisture from spoiling the mushrooms. Place them in a clean, tight-sealing freezer bag and ensure no weighty items are placed on top of the bags to avoid crushing.
- Check for worms: Before storing, check the mushrooms for any signs of worms or other pests. Properly cleaning the mushrooms before drying and storing is essential to remove dirt and debris that can affect their flavour and shelf life.
