Oyster mushrooms are a common edible fungi species found in the wild. They are easy to identify due to their oyster-shaped caps, short stems, and greyish-brown colour. They are typically found growing in clusters on decaying wood in deciduous forests. While oyster mushrooms are a nutritious food source, it is important to accurately identify them as they can be mistaken for poisonous look-alikes. Proper storage methods are essential to preserving oyster mushrooms, as they can quickly dry out or become slimy. Drying is a popular preservation method, but it must be done carefully to avoid discolouration and shrinkage.

What You'll Learn
Oyster mushrooms can be dried in the oven
Oyster mushrooms are indeed fleshy and big, so they cannot be dried whole. However, you can tear them into strips and dry them in the oven.
To dry oyster mushrooms in the oven, first, clean the mushrooms. You can rinse them a little and dry them off on paper towels. Then, tear the mushrooms into strips along the gills to a manageable size. Next, spread the mushroom strips on a clean dishtowel and loosely roll up the towel. Squeeze gently to remove any surface moisture. Place the mushroom strips on a baking sheet, making sure that none of the pieces overlap. Preheat the oven to 150°F (65°C) or 175°F (80°C) and place the baking sheet with the mushrooms in the oven for about one hour. After that, turn the mushroom strips over and return them to the oven for another hour. If the mushrooms are not completely dry, turn them over again and put them back in the oven for 30 more minutes. Keep checking for dryness every half hour.
Once the mushrooms are fully dried, allow them to cool completely before transferring them to covered glass jars. Label the jars with the variety of mushroom and the date of drying. Store the jars away from direct light or heat and use the mushrooms within a year or two. To rehydrate the mushrooms, place them in a heat-proof bowl and cover them with boiling water for 20 to 30 minutes or 1 to 2 hours. You can use the soaking liquid in your dish for added flavour.

They can be stored in airtight containers
Oyster mushrooms are a common mushroom found in the wild and are considered one of the easiest types of mushrooms to grow due to their fast growth, wide variety of potential substrates, and tolerance to growing conditions. They are also one of the most widely consumed mushrooms in the world and are known for their oyster-shaped cap and very short or absent stem. They are commonly found growing in layers on deciduous wood, particularly on dead hardwood trees like oak or beech trees.
When storing oyster mushrooms, it is important to note that they do not like sealed containers or plastic bags as they tend to get slimy. Instead, they can be stored in paper bags, although they may dry out within a couple of days. If you find a large quantity of oyster mushrooms, it is recommended to freeze or dry them for longer storage. To freeze, the mushrooms should be boiled for about 3 minutes, rinsed with cold water, drained, and then sealed in freezer bags.
Dried oyster mushrooms, on the other hand, should be stored in airtight containers and placed in a cool, dry area. To dry oyster mushrooms, preheat your oven to 150 degrees Fahrenheit and cut the mushrooms into slices about half a centimeter thick. Arrange them on baking trays and bake for an hour, then turn them over and bake for another hour. If they are not completely dry, continue drying in 30-minute increments until they are. Let them cool to room temperature, and then store them in the airtight container.
It is important to note that oyster mushrooms have poisonous look-alikes, so it is crucial to properly identify them before consuming them. Additionally, older oyster mushrooms tend to attract beetles, which can make them less appealing for consumption.

Oyster mushrooms are edible and nutritious
Oyster mushrooms are edible and highly nutritious. They are a group of gilled mushrooms that contain powerful plant compounds and are prized for their culinary uses. Oyster mushrooms can be identified by their oyster-shaped, silvery grey or greyish-brown caps and are usually found growing in layers on deciduous wood, such as dying or dead trees. They are easy to grow and can be cultivated commercially or at home.
Oyster mushrooms are a rich source of antioxidants, which help to reduce or prevent cellular damage in the body. They contain compounds such as flavonoids, phenolics, and ergothioneine, which is an amino acid that acts as a potent antioxidant and reduces systemic inflammation. Oyster mushrooms are also a good source of vitamin B, including vitamin B2, vitamin B3, and vitamin B6. Vitamin B3, in particular, aids in the breakdown of lipids, carbohydrates, and proteins, and is crucial for the growth and function of organs in the body.
In addition to their nutritional benefits, oyster mushrooms offer potential health advantages. They are a good source of dietary fibre and plant-based proteins, making them a suitable meat alternative for vegetarian and vegan diets. Oyster mushrooms may also promote heart health by reducing risk factors such as high cholesterol and high blood sugar levels. A study of 89 participants with diabetes found that consuming oyster mushrooms for seven days lowered their blood sugar, cholesterol, triglycerides, and blood pressure.
Oyster mushrooms are versatile in the kitchen and can be prepared in various ways. They have a meaty texture and a mild, savoury taste. They can be added to soups, stews, pasta dishes, stir-fries, and grain bowls. Oyster mushrooms can also be sautéed with olive oil and garlic as a side dish or chopped and incorporated into sauces, gravies, or egg dishes. When cooking with oyster mushrooms, it is important to note that they should not be washed or cleaned until just before use. They should be refrigerated in a paper bag and consumed within a few days, as they do not store well for extended periods.

Frequently asked questions
Oyster mushrooms are one of the easiest species to identify in the wild. They have oyster-shaped silvery grey or greyish-brown caps and usually grow in layers on deciduous wood, such as oak or beech trees. They are typically found in mid to late fall, but there are early spring oysters too, depending on the weather.
There are several ways to dry oyster mushrooms. One way is to use an oven—set it to 150 degrees Fahrenheit, cut the mushrooms into strips or slices about half a centimeter thick, and arrange them on baking trays. Bake for an hour, then turn them over and bake for another hour. If they are not completely dry, flip them and give them another 30 minutes until dry. Another way is to use a dehydrator or a very low oven on kitchen paper. Cut the mushrooms into small strips and dry them at a low temperature.
Yes, there are some lookalikes to avoid. One example is the elm oyster, which grows in Australia and Japan and is identified by its gills that do not run down the stem. While not poisonous, the elm oyster is reportedly not as tasty as a real oyster mushroom. The Omphalotus nidiformis, which grows in Japan and Australia, is another poisonous lookalike.
