What Are Shiitake Mushrooms?

The shiitake (Lentinula edodes) is also known as the golden needle mushroom, black forest mushroom, or winter mushroom. These tasty, edible fungi were previously only cultivated in Asia. They come from a group of about 20 different species within the Lentinus genus of mushrooms. The name “shiitake” is derived from a Japanese word for the tree they grow on.

In Asia, the shiitake mushroom is considered a “superfood” and has been prized for its medicinal benefits for centuries. In China, it was used as early as the Tang Dynasty (618-907). The fungus was historically used to treat difficulties with breathing, high cholesterol, fatigue, and low libido. It’s also thought to help protect the liver from toxins like alcohol.

Today, shiitake mushrooms are grown commercially in Japan, Korea, Taiwan, Russia, Thailand, Vietnam, China, Mexico, Australia, the United States (Oregon), France, Poland, Germany, and Canada.

Health Benefits Of Shiitake Mushrooms 

Shiitake mushrooms are good for many reasons, including these:

May Aid Heart Health

Shiitake mushrooms have three compounds that lower cholesterol for better heart health. They are:

  • Beta glucans – The polysaccharide beta glucans, found in the cell walls of all fungi and yeasts, is a fiber that is considered to be beneficial for heart health (6).
  • Sterols – Sterols block the absorption of cholesterol and decrease LDL (bad) blood cholesterol (7).
  • Eritadenine – This is a compound that can break down cholesterol. 

The combination of these three compounds works together to improve heart health (7).

May Help Prevent Cancer

Shiitake mushrooms contain lentinan, an active component that may help prevent and fight cancer. It’s even been approved as an adjunct chemotherapy treatment for advanced stomach cancer by the Japanese Ministry of Health. Cell studies have shown that lentinan may help activate immune cells, which is likely how it helps fight cancer (12).

Protects Against Free Radicals

Free radicals are molecules with an odd number of electrons, so they don’t have a stable electrical charge and can damage your cells. Shiitake mushrooms have a high amount of ergothioneine. This antioxidant helps fight free radicals and protect cells against their damage. It’s a great immunity booster, too (15)!

May Help Fight Fatigue

Shiitake mushrooms have been shown to increase your energy levels. They can make you feel less tired and improve mental activity because they contain a lot of the metabolism-boosting B vitamin, thiamin (1).

Helps Boost Immunity

A study showed that shiitake mushrooms increased white blood cell activity (lymphocytes) by 60%. This means your immunity is boosted to help fight disease and infections (4).

May Improve Digestion

The fiber in shiitake mushrooms can help improve your digestion because it helps you feel full longer. The mushrooms also contain lentinan, an active component that can break down food to make it easier for your intestines to digest (9).

May Help Relieve Menopausal Symptoms

The estrogen-like compounds in shiitake mushrooms may help relieve menopausal symptoms like depression and anxiety, insomnia, and water retention (17).

Potential Antibacterial And Antiviral Effects

Several compounds in shiitake have antibacterial, antiviral, and antifungal effects. These findings from test-tube studies show that the mushroom may be helpful in treating microbial infections. More human studies are needed to prove these effects on humans (2). 

May Boost Bone Health

Mushrooms are the only plant source of vitamin D. Vitamin D helps you absorb calcium, which is necessary for good bone health (16).

Shiitake Mushrooms Side Effects

There aren’t any serious side effects of eating shiitake mushrooms. Some people may have allergic reactions to them, but this is rare. Shiitake dermatitis is a skin allergy caused by the shiitake mushroom. It’s not serious, but it can cause inflammation on your skin and some itching (14).

Shiitake mushrooms are safe to eat during pregnancy and breastfeeding. They have no known drug interactions or side effects if you are taking medications. You should avoid eating raw mushrooms, though, because they may contain harmful bacteria.

Raw shiitake mushrooms also contain small amounts of the toxin coprine, which inhibits an enzyme (alcohol dehydrogenase) that metabolizes alcohol and can cause a disulfiram-like reaction if you drink alcohol after eating the raw mushrooms (10).

In addition, they contain purines that can increase your risk of gout attacks. Because of this, people who have gout or kidney problems should avoid eating them (13). They also contain fructose and glucose, so if you have diabetes you should limit or avoid eating them.

How To Cook With Shiitake

Mushrooms have a distinct umami flavor, which can be especially helpful when making vegetarian dishes or reducing your meat intake. You can cook with shiitake mushrooms by sauteing them in oil, then adding ginger, garlic, and your favorite vegetables.

These mushrooms are sold dried, so before cooking, you must soak them in water for 20 minutes. After you soak the dried shiitake mushrooms, they expand quite a bit and become more flavorful and chewy. You can keep their soaking liquid and use it to enhance your dishes, such as soups.

Cutting off the stems first is a good idea, as they may be too chewy. You can also keep the stems for making vegetable stock later. Then slice or chop them up and use them to replace meat in any recipe, such as stir-fries.

Finally, you can also marinate fresh shiitake mushrooms before cooking them on a skillet or grill.

Here are a few suggestions for cooking shiitake:

  • Saute them with other veggies and seasonings
  • Dredge them in egg and roll them in breadcrumbs before frying.
  • Grill or broil whole caps and then stuff with cheese, chopped veggies, and your favorite spices. 
  • Use the flavorful water to make a sauce for dishes like chicken or pasta.
  • Add them to pasta in place of meat in a vegetarian lasagna.
  • Add nutritional yeast for a cheesy flavor.
  • Eat shiitake in miso soup, which will also add more beneficial bacteria to your gut microbiome.

Caramelized Shiitake Mushroom Risotto (3)

Sure, risotto is good if you’re craving some carbs and comfort. You know what can make this dish taster and healthier, in other words, perfect? Shiitake mushrooms. Here’s how you make it:

Ingredients:

  • 3 1/2  to 4 cups vegetable broth (or store-bought)
  • 3/4 cup thinly sliced shallot
  • 1/4 teaspoon each sea salt and black pepper
  • 2 cups sliced shiitake mushrooms, hardy / woody stalked removed
  • 1 tablespoon coconut aminos (or tamari / soy sauce)
  • 1 tablespoon chopped fresh thyme
  • 1 cup arborio rice
  • 1/4 cup dry white wine, if desired
  • 1/4 cup vegan parmesan cheese (plus more for serving or some sub nutritional yeast)
  • Fresh chopped parsley, for serving

Instructions:

  • Start by heating the vegetable broth in a medium saucepan over medium heat. Once it starts immering, turn down the heat low to keep it warm.
  • Meanwhile, heat another large pan over medium heat until hot then add the oil and shallot. Season with a pinch of pepper and salt and let it saute for about 3 to 4 minutes, stirring frequently.
  • Now add in the coconut aminos and mushrooms and continue sauteing until the mushrooms turn golden brown and are perfectly caramelized. Optional: You can remove some of the shiitake mushrooms and reserve them for serving to complement the garnish.
  • Next, add the arborio rice and thyme then cook for about a minute stirring occasionally. Pour in the dry white wine, stirring ever so gently and continue cooking for an extra 2 minutes or until the liquid is mostly absorbed.
  • Use a ladle to add the warmed vegetable stock, 1/2 cup (120ml) at a time. Ensure you continuously stir the mixture, allowing the risotto little breaks to come back to a simmer. 
  • While the heat should always be at medium, you can adjust it to ensure the mixture is always simmering. Remember you want it to cook consistently, but not boiled so that it gets gummy and cooks too quickly.
  • Continue adding the vegetable stock, 1 ladle at a time while continuously stirring to incorporate. The rice should be ‘al dente’ – cooked through but retaining a slight ite. This process should take about 15 to 20 minutes.
  • Once the rice is perfectly cooked through, remove it from the heat and add the vegan parmesan cheese. Stir until well coated.
  • Taste, adjusting flavor as needed – adding pepper and sea salt to taste or more vegan cheese to enhance cheesiness. Add a little more warmed broth if it is still dry at this point.
  • Divide between serving bowls, topping with reserved mushrooms, a sprinkle of fresh parsley and additional vegan parmesan cheese to serve.
  • Enjoy when still fresh, though you can cover any leftovers and store in a refrigerator for 4 to 5 days or in a freezer for up to a month.
