Mush Ado About Barley: Creamy Mushroom Soup

Creamy vegan mushroom-barley soup with carrots and thyme in a ceramic bowl

Browned mushrooms, tender barley and everyday vegetables make this one-pot soup cosy and satisfying, while soy milk adds creaminess without weighing it down.

Grab this

  • 2 tablespoons olive oil
  • 450 g (1 lb) cremini mushrooms, sliced
  • 1 medium yellow onion, diced
  • 2 medium carrots, diced
  • 2 celery stalks, diced
  • 3 garlic cloves, minced
  • 1 teaspoon dried thyme
  • 3/4 cup (150 g) pearl barley, rinsed
  • 5 cups (1.25 L) low-sodium vegan vegetable broth
  • 1 tablespoon reduced-sodium tamari
  • 1 cup (250 mL) unsweetened soy milk
  • 2 tablespoons cornstarch
  • 1 tablespoon fresh lemon juice
  • 1/2 teaspoon ground black pepper
  • 1/4 teaspoon fine salt, plus more to taste
  • 2 tablespoons chopped fresh parsley, optional

Do this

  1. Heat 1 tablespoon of the olive oil in a large pot over medium-high heat. Add the mushrooms and cook for 7 to 9 minutes, stirring only occasionally, until their liquid has evaporated and the edges are browned. Transfer about one-quarter of the mushrooms to a small plate for topping.
  2. Add the remaining 1 tablespoon olive oil, onion, carrots and celery to the pot. Cook over medium heat for 5 minutes, stirring occasionally, until the onion begins to soften.
  3. Stir in the garlic and thyme and cook for 30 seconds. Add the rinsed barley, vegetable broth, tamari, black pepper and salt.
  4. Bring to a boil, then reduce the heat to maintain a gentle simmer. Partially cover and cook for 28 to 32 minutes, stirring every 8 to 10 minutes, until the barley is tender but still pleasantly chewy.
  5. Whisk the soy milk and cornstarch together in a measuring cup until no lumps remain. Slowly stir the mixture into the simmering soup.
  6. Simmer uncovered for 3 to 4 minutes, stirring often, until the broth looks creamy and lightly thickened. Remove from the heat and stir in the lemon juice.
  7. Taste and adjust the salt or pepper. Divide among four bowls and top with the reserved browned mushrooms and parsley, if using.

Easy swaps

  • Gluten-free: pearl barley contains gluten. Replace it with 2 cups cooked brown or wild rice and add the rice with the soy-milk mixture instead of simmering it for 30 minutes; check that the broth and tamari are certified gluten-free.
  • Soy-free: replace the soy milk with unsweetened oat milk and use coconut aminos instead of tamari. Allergen note: the listed recipe contains soy; oat milk may contain gluten unless certified gluten-free, and coconut aminos contain coconut.
  • No cremini mushrooms: use white button mushrooms in the same amount. If avoiding mushrooms, diced zucchini works, though the soup will be lighter and should cook for only 4 to 5 minutes before the vegetables are added.
  • Cornstarch can be replaced with 2 tablespoons arrowroot starch. Allergen note: check packaged broth, plant milk and tamari for cross-contact or added celery, mustard, wheat or other allergens relevant to your household.
