3 Ways to Dry Mushrooms

Dried mushrooms are wonderful – they are full of flavor, fantastic in many dishes, and can be stored for an eternity. You can rehydrate them and use them in soups, risottos, pastas… Just about any delicious recipe you can think of. Follow the steps outlined in this article to make your own dried mushrooms.


Method 1 of 3: Oven Drying Mushrooms

Dry Mushrooms Step 1

Step 1. Dry the mushrooms you are going to dry

If you can, use a brush or dry paper towel to remove any dirt contained in the mushrooms. Avoid getting them wet when cleaning, as water can cause other fungus or mold to grow on the mushrooms while they are drying or after they are stored. This extra fungus or mold can make you sick if you eat the mushroom.

  • If there are areas of dirt that you cannot remove with a brush, you can use a paper towel or damp cloth to scrub and remove them. Then wipe the same area with a paper towel or dry cloth to absorb any remaining moisture.

Step 2. Cut the mushrooms

The thicker, the longer it will take to dry. To speed up the process, cut the mushrooms into slices approximately 0.3 cm thick. There will still be enough flavor contained in the slices and will still be a great addition to any dish, but then the mushrooms will dry out in a much shorter period of time than if they were whole.

Step 3. Place the mushrooms on a baking sheet

They must be flat and side by side. No mushrooms should overlap, as this can bind them together when drying. Organize them into a single layer.

  • Do not grease the pans as the mushrooms will absorb the oil, changing the flavor and making them take longer to dry.

Step 4. Preheat oven to 65°C

When the oven has reached the designated temperature, insert the mushroom pan. Keep them in the oven for an hour.

Step 5. After an hour, remove the mushrooms from the oven

When removing them, turn them on their side to dry evenly. At this point, press and remove any moisture that has appeared on the surfaces during the drying process. Use a paper towel or dry cloth to do this.

Step 6. Put the mushrooms back in the oven

Bake for another hour or until completely dry.

  • When removing the mushrooms, check that there is still moisture on the surfaces. If there are, turn them over and tap them with a paper towel to remove any moisture, then return the mushrooms to the oven.

Step 7. Keep checking the mushrooms until they are completely dry

Repeat the roasting process and removing moisture until the mushrooms are completely dry. A properly dehydrated mushroom should crack like a cream cracker.

Step 8. Allow the mushrooms to cool

When you have removed the mushrooms from the oven, let them cool in the baking dish. Do not place them in a container with a closed lid while they are still hot, as the heat can cause condensation in the container, ruining all your efforts.

Step 9. Store dried mushrooms in airtight jars

When they have completely cooled, place the mushrooms in pots with lids that work. Keep in a cool, dark place until you're ready to use your mushrooms in a soup, pasta dish, or savory risotto.

Method 2 of 3: Drying Mushrooms Naturally

Dry Mushrooms Step 10

Step 1. Clean and slice the mushrooms

As described above, you should only clean mushrooms with a brush or dry towel. Do not use water, as water contained in mushrooms can cause external fungus or mold to grow. Cut the mushrooms into slices 1, 25 cm thick.

Step 2. Check the weather

Try this method only on sunny days with very low humidity. If there is a lot of moisture in the air, it will take much longer for the mushrooms to dry and mold can start to appear.

Step 3. Find a good drying location

Possibilities include sunny rooms, window sills, or flat roofs where air is circulated. Choose a location where birds, animals, insects and moisture do not come into contact with the mushroom.

Step 4. Arrange the mushrooms for drying

There are two options. You can place them on a wire shelf, or hang them with culinary string.

  • On the wire shelf: Flatten the mushrooms in a single layer. They should not overlap as they can stick together as they dry or deform into odd shapes. Cover with a "net" you can find at most kitchen supply stores. It will keep insects away. If you don't have this net, you can simply use a similar piece of fabric over and under the shelf and mushrooms.

  • With the string: Thread the culinary string through the mushrooms. You can use a sterilized needle to do this. Simply run the needle through a flame to sterilize it. Then thread the mushrooms through the string, as if you were making a bead necklace.

Step 5. Place the mushrooms in the location you selected for drying

If using the string method, hang it somewhere dry and in the sun. Let the mushrooms dry in the sun for a day or two. Check their progress several times a day.

  • You can finish the mushrooms in the oven if they are not completely dry after about two days in the sun. Read Method 1 in this article to learn how to do this.

Method 3 of 3: Freezer Drying Mushrooms

Dry Mushrooms Step 15

Step 1. Place a paper towel on a flat surface

Put the clean, sliced ​​mushrooms on the paper towel. They should be in a single layer, with no mushroom overlapping the other. If they touch, they could end up sticking together. It is very important to be absolutely dry. If they have the least amount of water, it can turn to ice and spoil the mushrooms.

Step 2. Put another paper towel over the mushrooms

Continue placing the mushrooms in a single layer and then placing paper towels over those layers until you are done arranging all the mushrooms you want to dry.

Step 3. Insert these mushroom and paper towel layers into a paper bag

You should use a bag that is big enough to hold all the paper towels and mushrooms. The paper bag will allow water vapors to pass through it while the mushrooms dry.

Dry Mushrooms Step 18

Step 4. Place the paper bag in the freezer

Over time, the mushrooms will start to dry in the freezer. This is a much slower process than the two methods described above, but it's effective – especially if you don't plan on using the mushrooms right away.


  • Use broth or boiling water to rehydrate dried mushrooms before using them.
  • Dried mushrooms have a stronger flavor than fresh mushrooms, so you'll need to use less in your recipes.
