What types of mushrooms can be dehydrated?

Any edible mushroom variety can be dehydrated. Crimini or baby bella, shiitake, portobello, button, chanterelle, porcini, oyster, etc .
The most important factor when choose mushrooms is to use the freshest mushrooms possible! Mushrooms that are past their prime will not store arsenic well and can start to smell “ off ” in your dehydrator .
To check for crust, break the shank from the hood. You should feel ( or even hear ! ) a snatch of a “ snap ” when the stem breaks off ( the exception is shiitakes–their stems are besides sturdy for this test ). If the mushroom feels cartilaginous or slimed, if it bends rather of breaks, or is starting to develop dark brown or black spots, that ’ s your sign that the mushrooms are not fresh enough to dehydrate .

Prepping mushrooms for drying

Before you start prepping your mushrooms, make sure your counters, equipment, and hands are clean & sanitized to prevent contamination, which can spoil your batch down the course .

  • Clean the mushrooms: Use a damp kitchen towel to gently clean any dirt or grit off your mushrooms. Avoid washing with water—while this won’t harm your mushrooms, it can cause them to darken during the dehydrating process.
  • Trim the stems: Remove any stems that are tough and stalky. (We save them to make veggie stock). You can then cut them off with a paring knife or tear them by hand.
  • Slice the mushrooms: Using a sharp knife, cut the mushrooms into ¼” slices. Alternatively, you can dice the mushrooms into small pieces if that works better for your end use.

How to dry mushrooms

Dehydrating mushrooms is reasonably simple and straightforward—a great ingredient for beginners ! once your mushrooms are prepped, set up your dehydrator and follow these steps :

  • Arrange the mushrooms on your dehydrator trays. If you’re using a tray that has large holes, we recommend that you line it with parchment paper or, even better, a mesh liner cut to the size of your tray. Leave space between the pieces to allow air to circulate.
  • Dehydrate at 125ºF (52ºC) for 3-8 hours until the mushrooms are brittle—they should break, not bend.
  • Depending on your machine, you may need to rotate the trays every so often to promote even drying.
  • Dehydrating using an oven: Place the mushrooms in a single layer on a lined baking sheet. Dry in the oven on its lowest temperature setting—if possible, keep the door propped open to allow steam to escape. Flip the pieces over every hour and remove as soon as they are completely dry.

Equipment Spotlight: Dehydrators

If you ’ re in the market for a dehydrator, we recommend buying one that has an adjustable temperature, which will allow you to dial in the dry temp to give you the best results for person ingredients. The dehydrator we recommend ( and use ) most often is the COSORI Premium. You can besides check out our best dehydrators position for a comparison of all the dehydrators we ’ ve used and would recommend .

How to tell when mushrooms are done

Mushrooms should be brittle when they are wholly dried. To test, let them cool, then break a few pieces. If they break easily, they are done. If the slices bend, put them back into the dehydrator or oven to dry longer .

To condition your mushrooms, let them cool completely and then place them in a big airtight container ( like a freemason jar ), seal, and leave it on your counter for a few days. Check it daily to make sure that there ’ s no moisture/condensation forming on the sides of the jar, and shake the contents to make surely they aren ’ thyroxine sticking together .
If you do notice that there is condensing, you can put it back into the dehydrator to dry for longer ( so long as there is no mold growing ) .
After a workweek, if there are no signs of moisture or cast, you can package your mushrooms for long-run storage .

How to store

When properly dried and stored, dehydrated mushrooms can last a year or more. hera are our tips for memory :

  • Let the mushrooms cool completely before transferring them.
  • Don’t skip the conditioning step! Even a little moisture can reduce shelf life or ruin an entire batch. 
  • Store in a clean, airtight container. For longer shelf life, vacuum seal.
  • Use a moisture absorbing desiccant packet if you anticipate opening the container often, or if you live in an area with high humidity.
  • Label the container with the date and any other important details.
  • Place the container in a cool, dark, and dry place—inside of a pantry cabinet works well.

Vacuum sealing tips

We like to store our dehydrated food in freemason jars that have been vacuum-sealed using this hand-held FoodSaver vacuum sealant along with these jar sealing attachments. This gives us the benefit of vacuum sealing without the lay waste to ( and expense ) of plastic vacuum sealing bags. Since the jars are clear we make certain we store them in a dark spot in our pantry to keep them out of direct light .
