Spoonful of mushroom barley soup.

Everybody knows by now how much I love soup, but it especially hits the spot on a cold day. On snowy days here in Michigan, a hearty bowl of soup is just what my soul needs. This Mushroom Barley Soup has been a favorite of mine for lunches throughout the week. Naturally vegan and vegetarian, it’s easy to make on a Sunday, then enjoy all week long!

Ingredients

Ingredients for Mushroom Barley Soup
  • Dried shiitake mushrooms: Having a strong umami flavor, once rehydrated they also have a meaty texture. Mushrooms are a great source of vitamins and antioxidants. You could also use fresh mushrooms, but the flavor won’t be as strong.
  • Olive oil: A mild flavored, heart-healthy oil to sauté the vegetables and mushroom before adding the broth.
  • Carrots: Slightly sweet in flavor, they stay a bit more firm in texture, and are a fantastic source of vitamin C.
  • Onion: I use a white onion to add mild, slightly sweet flavor as it sautés.
  • Celery: Very mild flavor, a bit of crunchy texture, and a great source of vitamins, calcium, and potassium.
  • White mushrooms: White button mushrooms are very mild in flavor, but caramelize nicely to increase the flavor of the soup while adding additional nutrients. You could also use baby bellas.
  • Barley: I use pearl barley as it has a faster cook time, and it’s a great source of iron, fiber, and magnesium.
  • Broth: To keep the dish vegan and vegetarian, use vegetable broth. Otherwise, I’ll often use chicken or beef stock.

How to Make Mushroom Barley Soup

Pouring hot water over mushrooms

Start your mushroom barley soup by putting your dried shiitake mushrooms in a bowl and covering them with hot water. Cover and set aside.

Veggies and mushrooms in pot

In the bottom of a large soup pot, heat the olive oil and add the diced veggies along with the sliced white mushrooms. Sprinkle with some salt and pepper, and sauté until vegetables have softened and begin to caramelize.

Once shiitake mushrooms have softened, strain them, saving about 1 1/2 cups of the mushroom water to add to the soup pot.

Roughly slice the softened mushrooms before adding to the pot.

Mushroom soup cooking

Add your chicken or vegetable broth and bring to a boil, then add the barley. Bring back to a boil before reducing the heat and simmering for about 45 minutes.

Frequently Asked Questions

Do you have to cook barley before putting it in soup?

The barley will cook while the soup simmers, so there is no need to cook it ahead of time.

Does pearl barley require soaking?

Hulled barley will cook quicker if it is soaked, pearl barley already cooks quickly and doesn’t need to be soaked.

Does barley thicken soup?

Because of the starch in barley, it will slightly thicken the broth.

    Liz I love your recipes.
    I been in food service for years and love a healthy approach to eating.
    42 years ago when I began in my profession, vegetarian approaches were considered an “alternative lifestyle” philosophy. Everything was seasoned with bacon fat.
    I remember at the age of 19 frying my eggs in olive oil, and buying organic food.
    The taste and quality of organic food was superior.
    Now all of this is mainstream.
    Thank You for adding choices for those who want to be fit, healthy, and conscious in their food choices.
