Mushrooms: both dried and fresh!

If you’re reading this, we’ll assume you’re mushroom lovers like we are. It took me years, but I finally learned to embrace the incredible flavor you can get from the humble mushroom, especially in plant based recipes.

For this recipe, you’ll use two types of mushrooms: both dried and fresh! Don’t be scared of the dried mushrooms: they’re very easy to use! If you’ve never worked with them before, here’s the down-low on using dried mushrooms:

  • Use any type. For this mushroom barley soup, you can use whatever type of dried mushroom you find at the store. Porcini is likely the easiest to find, but any will do.
  • Soak before using. Dried mushrooms needs to be dehydrated before using. For this recipe, you’ll soak the mushrooms for 30 minutes before adding to the soup.
  • Use the soaking liquid too. You’ll also pour in the mushroom soaking liquid into the soup, since that has lots of flavor too! Just make sure to strain out the liquid to make sure there are no tough parts of the mushrooms included.

Description

This favorite mushroom barley soup is full of vegetables, chewy barley, and warming broth. It’s a recipe for cozy on gray days!


Ingredients

Scale
  • ½ ounce dried mushrooms
  • 8 ounces baby bella (aka cremini) mushrooms*
  • 1 medium onion
  • 2 carrots
  • 2 stalks celery
  • 4 garlic cloves
  • 3 tablespoons extra virgin olive oil
  • 1 teaspoon dried basil
  • 1 tablespoon soy sauce
  • 1 quart vegetable broth
  • 1 cup pearled barley
  • ¾ teaspoon kosher salt
  • Fresh ground pepper

Instructions

  1. Soak the dried mushrooms in 2 cups of room temperature water for 30 minutes.
  2. Meanwhile, dice the onion. Peel and dice the carrots. Dice the celery. Slice the baby bella mushrooms. Mince the garlic.
  3. In a large pot or Dutch oven, heat the olive oil over medium heat. Add the sliced baby bella mushrooms, soy sauce, and basil. Cook 4 minutes. Add the onion, carrots, celery, and garlic and cook 5 to 6 minutes until softened. Stir in the barley and cook for 2 minutes. Add the vegetable broth and kosher salt.
  4. Bring to simmer and cook 25 to 30 minutes until barley is soft. Whenever the dried mushrooms are finished soaking (likely around when the simmering starts), remove and rinse them, then add them to the soup. Pour the remaining liquid through a fine-mesh strainer into the soup (this avoids any tough particles).
  5. Finish the remaining simmering time, then taste and add additional salt or pepper if desired. Ladle into bowls and serve warm.

Notes

*Substitute button mushrooms if you can’t find baby bella / cremini.

  1. This soup was divine. Used my own broth made from scraps. Added the beans. The highlight was your Dutch over bread. Great meal on a gray day!

  2. Hi, I am really interested in making this, but I really don’t like onions unless they are basically translucent and undetectable. I am worried that if I follow your directions and cook the mushrooms for only 5 or 6 minutes they won’t be as soft as I prefer. I am also worried that if I cook them longer that I might overcook the mushrooms. Any thoughts or suggestions?

    1. Hi! I think you could cook both the onions and garlic for 5 minutes before adding other ingredients and cooking 5-6 more minutes.

  3. Hi! Really looking forward to making this. Is there any way to substitute for hulled barley? I’m worried that the increased cooking time would make the vegetables overcook.

    Thanks very much :)
