Why dehydrate mushrooms?

Dehydrating mushrooms comes with various benefits. Here are some of them:

When compared to an ounce for ounce, dried food is more nutritious than fresh food. The same is true with mushrooms.

Mushrooms are made up of about 90% water. When you dry them, you get rid of all of this water, leaving a concentrated mixture of vitamins, protein, fiber, and antioxidants.


Dried mushrooms are special delicacies and infuse that umami flavor to food. Because of their unique earthy, spongy, and nutty taste, dehydrated mushrooms have become a great addition to different recipes. Not only that but mushrooms are meaty in texture, making them a good meat substitute.

How to dehydrate mushrooms?

Now, let’s go to our main topic.

There are different ways to dehydrate mushrooms and remove their water content. 

These are the following:

Now, let’s discuss them, one by one.

Using the sun to dry mushrooms

Sun drying

If you live in a tropical country or a sunny place, then you can easily dry your mushrooms under the sun.

How to dehydrate mushrooms under the sun

Drying mushrooms using the sun is pretty straightforward. Here are the basic steps:

  1. Clean the mushroom

    Please don’t use too much water. It can cause mold or fungi to grow. Use a dry towel or brush instead. If you use water, do a quick rinse and dry thoroughly.

  2. Slice your mushroom thinly

    ½ inch (1.25) thick should be thin enough for the mushrooms to dry quicker.

  3. Place the mushrooms on a drying tray

    While you can use any tray, you might want to use the one made of screen or mesh. This ensures that airflow both above and below mushrooms.

  4. Protect the mushrooms

    To better protect your mushrooms from insects, cover them with a net tent.

  5. Position the tray under the sun

    A good drying place could be rooftops, windowsills, and sunny rooms.

  6. Wait for the mushrooms to dry

    Depending on the weather, sun-drying mushrooms can take between 6-10 days.

Things to remember

When drying with the sun, be sure to check the weather forecast. Since drying could take several days, you must check whether it will be sunny for the next few days. 

Moreover, check the humidity level. Ideally, you want to sun dry your mushrooms when there’s very low humidity.

Too much humidity can slow down the drying process plus it adds moisture to your mushrooms, increasing the chances for mold to grow on it.

Pick a good location for drying. Aside from the amount of sunlight, you must be sure that the mushrooms are safe from bugs, birds, animals, and water.

Air drying

Air drying is another easy and inexpensive method of drying mushrooms. As long as you have enough airflow, this should work.

How to dehydrate mushrooms through the air?

The preparation and process are the same. However, it would be a good idea to use a cooking string instead of a drying rack.

Get your cooking string and attach one end to a sterilized needle. Lace the cooking string through the mushrooms as if you’re making a necklace.

From there, you can then find a place where you can hang your mushrooms. Of course, you can still use drying racks and place them in a shaded but dry area.

Sun plus air drying

Sun-drying can be faster if you combine it with air drying. This simply means that you’re going to place your mushrooms under the sun while ensuring it gets the maximum flow of air. With this, you might as well reduce drying time by about 20-30%.

If in case after a few days and your mushrooms are not yet fully dry, consider using other methods mentioned below.

Food dehydrator

While it is nice to use the natural power of the sun and air to dry your mushrooms, they might not be enough if time is of the essence.

This is where modern technology comes in.

Among the best appliances you can use is the food dehydrator. 

What is a food dehydrator?

A food dehydrator is a great machine to dry your mushrooms. Depending on what model you use, it can have multiple small fans or one big fan that distributes hot air throughout the food placed in it.

Air fryer drying

An air fryer is another great innovation that allows you to dry mushrooms in the quickest time possible. The steps of dehydrating mushrooms using an air fryer are almost the same as the food dehydrator.

How to dehydrate mushrooms using an air fryer

An air fryer comes with two chambers. The lower chamber is where you put your mushrooms. The upper chamber is the part where heat is produced and then a fan would push the hot air down to the lower chamber.

Understandably, air fryers are smaller compared to food dehydrators. So, it’s a good choice if you only have a few mushrooms to dry.

How to dehydrate mushrooms using an oven

Oven drying

Your oven is a work of innovation. It can do a lot of things. It will not just cook or bake food for you, but it can also dehydrate mushrooms.

How to dehydrate mushrooms with an oven

The steps and principles of drying are almost the same. Here are the steps to follow:


You need to clean them with a brush, tissue paper, or a little bit of water. Slice them thinly. Line your oven tray with baking sheets and spread your mushrooms on them.


Preheat your oven to 150 degrees Celsius. After five minutes, you can then put mushrooms in the oven. Keep the same temperature setting.


Cook for an hour. Flip over the mushroom and then cook for another hour.

After two hours of cooking, the mushrooms should already be dry. If not, you can cook for more minutes.

Once you’re done, you can cool down the mushrooms and store them accordingly.

Tips to remember

As you can see, dehydrating mushrooms is easy with the right knowledge and tools. To ensure that you will be successful in drying mushrooms, you may want to take note of the following:

how to dehydrate mushrooms

Choose the right mushrooms

When dehydrating mushrooms, it is a must that you only select the ones that are still in good condition. Don’t dehydrate mushrooms that have already started to decompose. 

For example, don’t select mushrooms that are slimy and wrinkly and those that have already shriveled up. Mushrooms that emit a bad odor or have already become darker are also not a good choice.

Properly storing dried mushrooms

Store correctly

The ideal storage condition of dried mushrooms should be cool, dark, and dry. You need to store dried mushrooms as well in an airtight container. When stored correctly, your dry mushrooms can last up to six to twelve months. 

Warmer and bright locations such as in an open kitchen or cupboard could shorten your mushrooms’ shelf life.

Good practice in storing mushrooms is to label your container. Indicate what type of mushrooms you have used and the date you dried them. 

Clean properly

According to some people, you should not use water in cleaning your mushrooms if you intend to store them for a while. The truth is that you can still use water. 

Mushrooms don’t soak up lots of water. However, if you’re going to prepare mushrooms for drying, only do a quick rinsing and dry them thoroughly.

Since mushrooms have different shapes and sizes, there are those mushrooms that are more difficult to clean because they come with lots of nooks and crannies. Good examples include maitake and oyster mushrooms.

If the mushroom of your choice is difficult to clean, it is okay to slice them first before cleaning. This allows you to clean hard-to-reach mushroom areas.

Sliced mushrooms for drying

Slice properly

The optimum thickness for sliced mushrooms would be ¼ to ½ inches. Remember, thicker mushrooms take longer to dehydrated. 

Of course, your choice of cut would also depend on your preference. If you like thicker slices of mushrooms, then that is still acceptable. Just remember how the thickness of the mushroom would affect the length of the dehydration process.

Final words

Yes, you can buy ready-made dried mushrooms and even mushroom powder, but wouldn’t it be nice to know how to do it yourself as well? You never know when the knowledge of drying mushrooms would be handy.

Dehydrating mushrooms is a great way of preserving and improving their taste. You can rehydrate the mushrooms by soaking them for 20 to 30 minutes. Rehydrated mushrooms can sometimes even be more delicious than fresh mushrooms.

Whether you are preparing soup or sauce, dried mushroom slices should be your best choice. Now that you know how to prepare dried mushrooms, you have a whole lot of new recipes to try!
