Shiitake Mushroom: Recipes

Buy fresh or dried mushrooms and add them to soups, stir-fries, or side dishes. Soak dried mushrooms in water for a few hours or overnight before adding them to food.

Shiitake Mushrooms And Brown Rice

Start the brown rice before you start the mushrooms. (Although brown rice takes a little longer than white rice [about 45 minutes], it is well worth the wait because it has more vitamins, minerals, and flavor). Add fresh or rehydrated shiitake mushrooms (whole or sliced) to a saute pan to which you’ve also added olive oil. Add a few onions and garlic, and then add the cooked rice.

Medicinal Mushroom Soup

Make a soup out of 50 grams of fresh or dried shiitake mushrooms, vegetables, grains, and beans. This combination offers a wonderful way to boost the immune system and reduce the side effects of chemotherapy and radiation therapy.

Infection Buster

Add 1 to 3 shiitake mushrooms per person (including children) to stir-fries, vegetables, or chicken soup to help ward off winter illnesses.
