Shiitake mushrooms are a staple of East Asian cuisine and are commonly used in Japanese and Chinese cooking. They are the second most commonly consumed edible mushroom in the world, with an estimated 10,000 tons eaten per year. While they are typically cooked, some people enjoy eating them raw. However, it is important to note that eating raw or undercooked shiitake mushrooms can cause an itchy rash called shiitake dermatitis or flagellate dermatitis. This rash affects only around 2% of people who eat the mushrooms raw or undercooked, and it typically appears 24 to 48 hours after consumption. So, are shiitake mushrooms safe to eat?

Shiitake mushrooms can be eaten raw
Fresh shiitake mushrooms can be eaten raw and are commonly used in salads, sushi, and sashimi. They offer a delicate texture and a distinctive earthy flavor. However, it is important to ensure they are fresh and free of debris by gently cleaning them under running water before consumption.
Shiitake mushrooms are commonly cooked in various dishes, such as stir-fries, soups, and stews. Cooking enhances their umami flavor and tender texture. It is believed that cooking these mushrooms improves their taste and reduces potential toxins or indigestible components, making them more digestible and safer for consumption.
While shiitake mushrooms can be eaten raw, there are some considerations to keep in mind. Some individuals may experience mild gastrointestinal discomfort or a unique form of skin irritation known as shiitake dermatitis, resulting in itchy and painful rashes. Cooking shiitake mushrooms to a temperature of 266-293 degrees Fahrenheit can neutralize the toxicity of lentinan, a polysaccharide present in the roots of this mushroom, which is thought to cause the rash.
When preparing raw shiitake mushrooms, it is recommended to slice them thinly and add them to dishes such as sushi rolls with cucumber, avocado, and pickled radish, or serve them with soy sauce and wasabi. They can also be scattered over a salad or a plate of fresh nachos for extra nutrition and flavor.

Cooking shiitake mushrooms
Shiitake mushrooms are a versatile ingredient that can be cooked in a variety of ways. They have a buttery, full-bodied flavour with a distinct earthiness and are commonly used in Japanese and Chinese cuisine. Here are some tips and recipes for cooking shiitake mushrooms:
Preparation:
Shiitake mushrooms should be cleaned before cooking. This can be done by gently wiping each mushroom cap with a damp paper towel to remove any dirt or debris. Alternatively, you can quickly rinse them in a colander and then dry them with a paper towel. The mushrooms do not need to be completely dry before cooking. After cleaning, remove the stems by cutting them off with a knife. The stems are edible but can be tough and fibrous, so you may choose to save them for making vegetable stock later.
Cooking Methods:
Shiitake mushrooms can be cooked whole or sliced. They can be baked, sautéed, or pan-fried.
Baking:
To bake shiitake mushrooms, preheat your oven to 400°F. Coat the mushrooms with a mixture of olive oil, white wine vinegar, and spices. Spread them on a rimmed baking sheet and bake for about 20 minutes. Serve immediately.
Sautéing:
Sautéing shiitake mushrooms is a quick and easy method. Slice the mushrooms and cook them in butter over medium heat for about 5 minutes, until tender. Season with salt, pepper, garlic powder, and dried thyme. Serve immediately.
Pan-frying:
To pan-fry shiitake mushrooms, heat a pan over medium heat. Add the mushrooms and cook for about 5 minutes, until tender and lightly browned. You can also add additional ingredients such as onion or garlic to the pan for extra flavour.
Recipes:
Shiitake mushrooms are a great addition to many recipes. Here are some ideas:
- Mushroom soup: Silky and one-pot dish that will satisfy any mushroom lover.
- Mushroom and Pea Pasta: A veggie-packed meal with creamy ricotta cheese and zesty lemon.
- Vegetable Ramen: Combine with mushrooms and bok choy, adding ginger, tamari, and miso.
- Asian-style sautéed mushrooms: Sauté shiitake slices with onion or shallot. Finish with a drizzle of garlic butter sauce for an authentic Asian flavour.

Nutritional value of raw shiitake mushrooms
Shiitake mushrooms are native to East Asia and have been used in traditional Chinese medicine and the medical traditions of Japan, Korea, and Eastern Russia. They are now cultivated in several countries and are popular worldwide for their taste and health benefits.
Shiitake mushrooms are low in calories and contain good amounts of fiber, B vitamins, vitamin D, zinc, choline, copper, and selenium. They also contain polysaccharides, terpenoids, sterols, and lipids, some of which have immune-boosting, cholesterol-lowering, and anticancer effects. The amount of bioactive compounds in shiitake depends on how and where the mushrooms are grown, stored, and prepared.
A cup of shiitake mushrooms (approximately 145 grams) provides about 81 calories, 2.3 grams of protein, 21 grams of carbohydrates, and 0.3 grams of fat. The mushrooms also contain natural sugar, with 5.6 grams of sugar per cup of cooked shiitake.
In rare cases, some people may experience an allergic reaction to raw shiitake mushrooms due to the presence of a compound called lentinan, which can cause skin dermatitis. Cooking the mushrooms can help to avoid this reaction, but it may also reduce the health benefits provided by lentinan.

Shiitake dermatitis
The symptoms of shiitake dermatitis include linearly arranged erythematous, pruritic papules on the trunk and limbs. Some patients may also experience other symptoms, such as intense itching, skin lesions, and perilesional petechiae. In rare cases, raw shiitake mushrooms can also induce contact allergic dermatitis in sensitised individuals.
The diagnosis of shiitake dermatitis is typically based on the patient's history of recent mushroom ingestion and the appearance of the rash. There are no specific laboratory findings for this condition. Treatment options include oral antihistamines, topical steroids, and avoiding the consumption of raw shiitake mushrooms. Most patients recover completely within 3 weeks, with or without treatment.
It is important to note that while shiitake mushrooms are commonly consumed raw, some individuals may have sensitivities to them. Cooking shiitake mushrooms is generally recommended to prevent the risk of shiitake dermatitis and to improve their taste and texture.

Buying shiitake mushrooms
Shiitake mushrooms are one of the most popular and versatile mushrooms worldwide. They are commonly used in Japanese and Chinese cuisine and are the second-most commonly consumed edible mushroom globally, with an estimated 10,000 tons eaten per year.
Shiitake mushrooms can be purchased fresh or dried. Fresh shiitake mushrooms are available from specialty grocers, such as D'Artagnan, and some mushroom farms, like River Valley Ranch, sell them directly to consumers. When buying fresh shiitake mushrooms, look for those cultivated in pristine conditions without the use of chemicals, preservatives, or growth enhancers.
After purchasing fresh shiitake mushrooms, store any unused product in its original packaging or a brown paper bag. To clean, gently wipe the caps with a damp paper towel, and always remove the stems before cooking.
Dried shiitake mushrooms are widely available from online retailers such as Amazon and specialty grocers. They are a convenient option, as they have a longer shelf life than fresh mushrooms and can be easily rehydrated in hot water before use. Dried shiitake mushrooms are also a good value, as a large bag can cost around $20.
When buying shiitake mushrooms, whether fresh or dried, it is important to consider any potential sensitivities or allergies. While generally considered safe to consume raw, some people may experience Shiitake Dermatitis, a skin irritation resulting in itchy and painful rashes. To avoid this, cook shiitake mushrooms for at least 5-7 minutes until they are tender and lightly browned, ensuring they reach an internal temperature of 266-293 degrees Fahrenheit.
