Can You Dry Oyster Mushrooms?

What about dried oyster mushrooms, though? Although I have never seen dried oysters for sale, I knew it could happen. They can be torn into strips but are too large and meaty to be dried whole. A helpful blog on the issue can be found at Montana Mushrooms by Dean.

“You frequently find more oyster mushrooms when you locate a good source than you can immediately consume. You would be better off storing some oysters for the chilly winter months because they don’t store or keep for very long after being picked. My preferred method of preserving mushrooms is by drying them. After finishing the harvest and giving some away, I dried the extra. The procedure is basic and straightforward. Cleaning the mushrooms comes first. Given that they were made from coffee grounds, this batch was relatively clean. They needed a little rinse, and I dried them with paper towels. The mushrooms were then cut into manageable size by tearing them along the gills. This batch spent several days drying on counter-top racks.”

“We use a dehydrator to dry vast quantities of mushrooms or meaty mushrooms. Before you put them in jars, the most important thing is to make sure they are absolutely dry. At this time, they are stored in labeled Mason jars. You can slightly boil mushrooms in water to rehydrate them. Make sure the broth is consumed or saved. Where the flavor is, is here! Rehydrating in milk is effective, especially if you plan to cook the food in flour or make gravy. I like to add them to soups or sauces and let the liquid of the dish rehydrate them. Dried-mushroom soups are excellent and, in most situations, superior to fresh-mushroom soup. So, harvest when you can, consume what you can, and store the remainder. In the months when the mushrooms aren’t flushing, you’ll be glad you did!”

There are three primary techniques you can employ:

1) Spread them out on kitchen paper in a roasting pan and bake them in a low oven.

2) Lay them out on kitchen paper in a roasting pan and keep them in a warm airing cupboard.

3) Set them on top of a wood-burning stove on a roasting rack.

The woodburing stove approach proved to be the simplest for us after trying all three. The mushrooms were placed in a glass jar with a cover after being left on the rack for two evenings. Making sure the mushrooms were completely dry before sealing the jar, we kept it open for another evening (so they do not rot). They will turn to powder if you dry them for too long.

The airing cupboard solution worked for us, however ours isn’t extremely hot. We have a well-insulated water tank that doesn’t heat up. Therefore, we made the decision to finish them off in the woodburner.

I admit we didn’t test the last technique, which involved baking on kitchen paper in a very low oven. We already had a woodburner heating the house, so it just seemed foolish to waste the energy, although we have before baked dried mushrooms in the oven. The most important thing to keep in mind is that you do need to make sure the oven is on low and that you are drying little strips.

Make mushrooms that are dehydrated without a dehydrator

When you bring home a profusion of fresh, foraged mushrooms, you don’t want them to go to waste because they are a seasonal food. Drying is used in this situation. A great addition to many recipes, including pasta, risotto, soups, and sauces, are dried mushrooms. But frequently they can be pricey or difficult to find. Fortunately, you can create them at home, which is ideal if you have wild mushrooms from the farmers market.

Most mushrooms dry out perfectly. Even the drying process gives them taste. Mushrooms that have been dried can be kept for at least a year, and when they are rehydrated months later, their texture is quite similar to that of fresh mushrooms. Even though a dehydrator is the ideal method for drying mushrooms, you can achieve excellent results using your home oven by following a few straightforward steps.

You can preserve the flavor of a variety of mushrooms all year long if you have an oven, some baking sheets, and jars.

Long-Term Retention

Cut your oyster mushrooms into chunks that are all the same thickness before drying. I cut my stems in half and removed them. The remaining caps were then divided into halves or quarters, depending on their size.

Although high temperatures speed up the drying process overall, a consistent 115 degrees F is preferable. To preserve flavor and nutrition, dehydrate for a number of hours at this temperature.

Pack your mushrooms into clean, dry, airtight containers after they have dried and cooled completely. But not least, what? Be sure to mark each mushroom kind, along with the dates of harvest and packing.

Dehydrating (up to 6 months)

On the shelf, dehydrated mushrooms can last up to six months. Mushrooms are often dried for commercial use using a vacuum or other sophisticated dehydrating apparatus.

The most straightforward method for dehydrating mushrooms at home is with a food dehydrator. If a dehydrator is not available, a conventional oven with a wire rack or a microwave would work just as well. Air drying them in the sun is another simple method.

This study compared four drying techniques (freeze-drying, also known as lyophilization, sun-drying, microwave drying, and hot air drying), and discovered that while it is simpler to rehydrate mushrooms after freeze-drying and sun-drying, microwave drying and hot air drying actually retained the most nutrients, particularly iron.

If you find yourself asking “why so small?” Don’t worry if your mushrooms start to dry out; that’s normal. They will significantly reduce in size when dehydrated, but their flavor is unaffected. You can use them just like fresh mushrooms after rehydrating them by soaking them in water for a short time.


The caps of dried oyster mushrooms are often flat, shriveled, wrinkled, and slightly curved, with little to no stems, and they range in size from 2 to 5 centimeters in diameter. Additionally, some dried oyster mushrooms are sliced into bits and dehydrated, resulting in a variety of forms and sizes. The dried mushrooms have a light brown to pale grey appearance and are brittle, delicate, and slightly leathery. Dried gills are compressed and run the length of the mushroom cap underneath the cap. Before using, dried oyster mushrooms must be reconstituted. Once done, the mushrooms have a mild, sweet, and earthy flavor, as well as a little chewy, tender, and meaty texture.

Wild mushroom drying without a dehydrator

A dehydrator is not necessary, although it is great to have one. Here are some methods you might try and some troubleshooting advice for drying mushrooms without a dehydrator.

  • The mushrooms should be thinly sliced.
  • One of the oldest methods is to thread sliced mushrooms with a needle and string, hang them up, and allow them to air dry outside.
  • If you want the mushrooms to dry completely, blow a fan on them continuously.
  • arranging sliced mushrooms on outdoor screens or in a dry location
  • Continue to leave the mushrooms out if they feel the smallest bit wet.
  • It also works to place the mushrooms on a cooling rack in an oven set to warm as long as the temperature isn’t hot enough to cook them; however, I prefer to keep the oven door slightly ajar.

Can king oyster mushrooms be dried?

The sun must be used to dry off king oyster mushrooms. They will also dry indoors, but it seems that being exposed to the UV rays of the sun increases their nutritious value. Depending on how you intend to use them, slice or shred the king oyster mushrooms (either lengthwise or sideways) before drying them.

Do dried oyster mushrooms taste good?

Similar to their fresh version, dried oyster mushrooms are an excellent source of fiber to maintain the digestive system, vitamin D to maintain phosphate and calcium levels, potassium to balance bodily fluids, and B vitamins to turn food into energy. The mushrooms also include calcium and phosphorus to strengthen bones and teeth, copper to develop connective tissues, folate to produce healthy red blood cells, and other nutrients.

How are oyster mushrooms air dried?

Start with fresh mushrooms; mushrooms that are past their prime won’t clean up with this technique. Use a cloth that has been mildly wet. NOT to be washed with running water.

Put them in a container with airflow around them, either a mesh colander or a baking rack placed on top of a baking sheet. Don’t crowd the mushrooms too tightly.

Put them in a room that is properly aired (or any room in the house where fresh air is readily available), preferably in the sun if you can. After 7 to 10 days, they should no longer yield when squeezed. Depending on the humidity levels and the size of the mushrooms, drying times will change.

You can air dry them after a partial dehydration in the oven to speed up the process. Place them in an oven set to 175 degrees Fahrenheit/80 degrees Celsius for two hours, turning them over halfway. I put the mushrooms on an oven-safe plate, but you could also put them on a baking rack over a sheet pan.

The mushrooms will then have partially dried. Place them in a colander and let them air dry for a further 3-5 days.

Once they are completely dry, smell them. They’ll smell fantastic. For up to a year, keep them in a sealed container (be sure the mushrooms are COMPLETELY dried before sealing them away). Soak them in warm water for a couple of hours to rehydrate them before cooking. If at all feasible, cook using the soaking liquid since it is flavorful.

Can you preserve mushrooms by drying them?

Drying is a fantastic technique to keep extra gourmet mushrooms from spoiling at the back of your refrigerator.

A year-round supply of delectable seasonal mushrooms can also be obtained by drying or dehydrating mushrooms.

However, even if your freezer is small and has little place, you can always find a shelf or a cellar with more area to keep dried mushrooms.

Another benefit of drying mushrooms is that it brings out more of their mouthwatering umami flavor.

Porcini, morel, black trumpet, matsutake, and, perhaps the most well-known of these, shiitake mushrooms are a few examples.

In Asian cooking, dried shiitake mushrooms are a standard component. Their potent taste is used to improve broths, soups, and stir-fries.

For individuals who dislike the feel of fresh mushrooms, drying the mushrooms is also the first stage in creating mushroom powder.

You may enjoy the flavors and health advantages of mushrooms in new ways by adding mushroom powder to a variety of drinks and foods.

Use damaged mushrooms that you might not want to offer fresh by drying them instead.

How long do oyster mushrooms take to dry?

Once your mushrooms have been thinly cut, lay them on the dehydrator tray. However, there is a specific manner to place your mushrooms for the best results.

In order to dehydrate as many mushrooms as you can in a single batch, we advise placing your mushrooms very closely together. How near is too near? Simply make sure the borders aren’t touching, as moisture can accumulate in overlapping regions. Kissing mushrooms lack the necessary ventilation to fully dehydrate, while close mushrooms dry more quickly and evenly.

The more mushrooms you can fit on the tray, the better, as mushrooms significantly contract once dried. Between 110 and 120 degrees Fahrenheit, dry the sliced mushrooms until they are crisp. For 1/4-inch slices, the process typically takes 6 to 8 hours, but larger slices could take up to 10 hours. As different brands may have varied drying times, always adhere to the detailed directions that came with your dehydrator.
