How To Dry Mushrooms — Full Guide

how to store mushrooms

Drying mushrooms is an excellent way to preserve them for long-term storage and to intensify their flavor. Here’s a step-by-step guide on how to dry mushrooms using different methods:

Preparation

Start by choosing fresh and firm mushrooms. Avoid any that feel slimy or have dark spots, as these are signs of decay and will not dry well.

Next, clean the mushrooms thoroughly. Use a damp cloth or a soft brush to gently remove any dirt or debris. Be careful not to wash them under running water, as mushrooms tend to absorb water quickly, which can hinder the drying process.

After cleaning, slice the mushrooms into uniform pieces, approximately 1/4 inch thick. This uniformity ensures that all slices dry evenly and at the same rate.

Mushroom Drying Methods

The three key methods for drying mushrooms are air drying, oven drying and using a dehydrator. 

1. Air Drying

Air drying works best for smaller mushrooms or thin slices.

Begin by placing the mushroom slices on a wire rack, ensuring they do not overlap. This setup allows air to circulate freely around each slice.

Next, position the rack in a well-ventilated area with low humidity. Avoid direct sunlight, as it can cause the mushrooms to dry unevenly and lose their flavor.

Allow the mushrooms to dry for several days to a week. During this period, turn the slices occasionally to promote even drying. This method requires patience but yields excellent results.

2. Oven Drying

Oven drying is a faster method and can be done with any standard oven.

How to dry mushrooms in the oven?

Start by setting your oven to the lowest temperature setting, usually around 150°F (65°C). This gentle heat will dry the mushrooms without cooking them.

Place the mushroom slices on a baking sheet lined with parchment paper. Ensure the slices do not overlap to allow for even drying.

Put the baking sheet in the oven, and keep the oven door slightly open to let moisture escape. Check and turn the slices every hour to ensure they dry evenly.

Depending on the thickness of the slices and their moisture content, this process can take anywhere from 2 to 8 hours. Monitor them closely to avoid over-drying.

3. Dehydrator

Using a dehydrator is the most efficient and reliable method for drying mushrooms.

Begin by laying the mushroom slices on the dehydrator trays in a single layer. This arrangement allows for maximum air circulation around each slice.

What Temp to Dehydrate Mushrooms?

Set the dehydrator to 125°F (52°C), the optimal temperature for drying mushrooms without compromising their flavor.

Dry the mushrooms for 4 to 12 hours, depending on their size and moisture content. Periodically check the slices and rotate the trays if needed to ensure uniform drying.

By following these steps, you can effectively dry mushrooms using the method that best suits your needs and equipment.

Mushrooms are fully dried when they are brittle and break easily. There should be no sponginess or moisture left.

How To Store Dried Mushrooms

After drying the mushrooms, allow them to cool completely. This step is crucial because any residual heat can create condensation, which may lead to mould growth during storage.

Use Airtight Containers

Once the mushrooms are cool, store them in airtight containers or vacuum-sealed bags. Airtight containers prevent moisture from entering and spoiling the dried mushrooms. Vacuum-sealed bags are especially effective because they remove excess air, further protecting the mushrooms from moisture and air exposure.

Place in a Dark, Cool Location

Next, find a dark, cool, and dry place to store the containers. Direct sunlight or heat can degrade the quality of dried mushrooms over time, affecting their flavor and texture. A pantry or a cupboard away from heat sources is ideal. When stored properly, dried mushrooms can maintain their quality for a year or more.

By following these steps, you ensure that your dried mushrooms remain flavorful and ready for use in your favorite dishes for an extended period.

How To Rehydrate Dried Mushrooms


To rehydrate dried mushrooms, start by soaking them in warm water. Place the mushrooms in a bowl and pour enough warm water over them to cover them completely. Let them soak for 20 to 30 minutes. This process allows the mushrooms to absorb the water and regain their original texture and shape.

Once the mushrooms have rehydrated, don’t discard the soaking liquid. This liquid is infused with the concentrated flavors of the mushrooms and can be a valuable addition to your cooking. Strain the liquid through a fine mesh sieve or a coffee filter to remove any grit or impurities. Then, add this flavorful liquid to soups, stews, sauces, or risottos to enhance their taste.

By following these steps, you can effectively rehydrate dried mushrooms and utilize the soaking liquid to enrich your dishes with deep, mushroomy flavors.

Dried vs. Fresh Mushrooms

Drying mushrooms concentrates their flavour, resulting in a more intense and robust taste compared to fresh mushrooms. This intensified flavor adds depth and complexity to dishes, especially soups, stews, sauces, and risotto.

Also, they have a much longer shelf life than fresh ones. Properly dried and stored mushrooms can last for a year or more, making them a convenient pantry staple for whenever you need them.

On top of that, Dried mushrooms are incredibly versatile and can be used in a wide range of recipes. Their concentrated flavor allows them to stand out in dishes, even when combined with other ingredients.

Lastly, they are lightweight and compact, making them easy to store and transport. They take up less space in your pantry and are ideal for camping trips, hiking, or travelling when fresh ingredients may not be readily available.
