What You'll Learn
Where to grow them
Buna-shimeji mushrooms can be grown both indoors and outdoors. In the wild, they are often found growing in dead or decaying beech trees, as well as in cottonwood and elm trees. They are native to East Asia but are also found in northern Europe and North America.
If you want to grow them outdoors, you can try to replicate their natural environment. They grow in large clusters of small mushrooms on beech wood. You can also grow them in a bed of grain, sawdust, and other organic materials, as is done in commercial cultivation.
To grow them indoors, you can purchase mushroom kits that provide the necessary substrate and growing conditions. These kits often include a layer of leaves or other suitable material on top of the substrate for the fruit bodies to grow on.
Buna-shimeji mushrooms are increasingly common in grocery stores, particularly in Asian grocery stores or areas with large East Asian populations. However, growing them at home can be a rewarding experience and provide a healthy addition to your meals.

They are considered the “authentic” shimeji cultivars and grow in large clusters of small mushrooms on beech wood. They can be found growing wild in parts of North America, Europe, and East Asia, but they are far more easily obtained from commercial operations, especially given their habit of growing high up on trees.
Commercially cultivated buna-shimeji mushrooms are grown in a bed of grain, sawdust, and other organic materials. They are commonly grown in Asia and North America and are used in Asian cooking. They can be sautéed or included in stir-fries.

How to cook them
When it comes to cooking Bunashimeji mushrooms, there are several delicious methods to choose from. Here is a step-by-step guide on how to prepare and cook these tasty mushrooms:
Preparation:
Start by gently separating the mushrooms. Bunashimeji mushrooms are typically sold in clusters, and you want to separate them into small bunches or individual mushrooms. You can do this by hand, being careful not to damage the delicate stems. Remove any debris or dirt by brushing the mushrooms lightly or using a damp paper towel to wipe them clean. Rinsing them quickly under cold running water is also an option, but make sure to dry them afterward using a paper towel or a clean cloth.
Sautéing:
Sautéing is a quick and easy way to cook Bunashimeji mushrooms. Heat a small amount of butter or olive oil in a pan over medium heat. Once the butter has melted or the oil is hot, add the mushrooms. Sauté them for about 3-5 minutes, stirring occasionally, until they are golden brown and slightly crispy. Season with salt and pepper to taste. You can also add fresh herbs like thyme or chives toward the end of cooking for extra flavor.
Stir-frying:
Stir-frying is another excellent method for cooking Bunashimeji mushrooms. Heat a small amount of vegetable oil in a wok or large skillet over high heat. Add the mushrooms and stir-fry for 2-3 minutes, constantly stirring or tossing them in the wok to ensure even cooking. You can also add other vegetables to the stir-fry, such as onions, bell peppers, or carrots. Season with soy sauce, ginger, garlic, or your favorite stir-fry sauce.
Grilling:
Grilling Bunashimeji mushrooms imparts a delicious smoky flavor. Thread the mushrooms onto skewers, alternating them with other vegetables like zucchini, eggplant, or bell peppers if desired. Brush the mushrooms with olive oil and season with salt and pepper. Place the skewers on a preheated grill over medium heat and cook for about 2-3 minutes on each side, until they are slightly charred and tender. You can also wrap the mushrooms in foil with butter and herbs and place them on the grill for a smokier flavor.
Roasting:
Roasting Bunashimeji mushrooms intensifies their flavor and makes a great side dish. Preheat your oven to 400°F (200°C). Toss the mushrooms with olive oil, salt, and pepper, and spread them out on a baking sheet. Roast for 10-12 minutes, stirring halfway through, until they are golden brown and slightly crispy. You can also add other vegetables to the baking sheet, such as asparagus, carrots, or potatoes, for a complete roasted vegetable dish.
Remember, Bunashimeji mushrooms have a delicate flavor and texture, so take care not to overcook them. They are best served when they are just tender and slightly browned. Enjoy your freshly cooked mushrooms as a tasty addition to pasta dishes, salads, omelets, or as a savory side.

How to store them
When it comes to storing Bunashimeji mushrooms, there are several methods you can use to ensure their freshness and prolong their shelf life. Here are some detailed instructions on how to store them:
Freshly harvested Bunashimeji mushrooms are perishable and should be consumed or properly stored within a few days of harvesting. One popular method for short-term storage is to keep them in the refrigerator. Place the mushrooms in a paper bag, or a container with a paper towel, and then put them in the fridge. This helps to absorb excess moisture and keeps the mushrooms dry. Make sure the storage container has good air circulation to prevent the buildup of moisture, which can lead to spoilage. Stored this way, the mushrooms will stay fresh for about a week.
Another method for short-term storage is to wrap the mushrooms in a dry, absorbent material such as paper towels or kitchen cloth. This helps to wick away moisture and keeps the mushrooms from becoming slimy. Change the paper towels regularly to maintain dryness. You can also place the wrapped mushrooms in an open container or a mesh bag to allow for air circulation while still retaining some humidity. This method is ideal for short-term storage, usually up to a week.
For long-term storage, consider freezing or drying the mushrooms. To freeze Bunashimeji mushrooms, first, make sure they are clean and dry. Then, place them in a single layer on a tray or plate and put them in the freezer. Once they are frozen solid, you can transfer them to a sealed container or freezer bag. This way, you can keep them for several months. When you're ready to use them, simply take out the desired amount and add them directly to your dish; they don't need to be thawed first.
Drying is another effective method for long-term storage. Slice the mushrooms thinly and place them in a dehydrator or your oven at its lowest setting until they are completely dry. You can also air-dry them in a warm, dry place, although this method may take several days. Once they are dried, store the mushrooms in airtight containers or jars and keep them in a cool, dark place. Properly dried mushrooms can last for months and can be reconstituted by soaking them in warm water for about 20 minutes before using them in your recipes.
With these storage methods, you can enjoy fresh and flavorful Bunashimeji mushrooms for weeks or even months. Remember to inspect your mushrooms regularly during storage and discard any that show signs of spoilage to prevent the rest from deteriorating. By following these instructions, you can maximize the shelf life of your Bunashimeji mushrooms and minimize waste.
