Ingredients

  • 1 cup pearl barley, rinsed
  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 3 cloves garlic, minced
  • 3 cups mushrooms (button or cremini), sliced
  • 2 medium carrots, diced
  • 2 stalks celery, diced
  • 6 cups vegetable broth (low sodium preferred)
  • 1 teaspoon dried thyme
  • 1 bay leaf
  • Salt and pepper to taste
  • 2 tablespoons fresh parsley, chopped (for garnish)
  • Optional: splash of soy sauce or tamari for umami depth

Equipment

  • Large heavy-bottomed pot or Dutch oven
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Knife and cutting board
  • Ladle for serving
  • Fine-mesh strainer (for rinsing barley)

Instructions

  1. Prepare the barley: Rinse the pearl barley under cold water using a fine-mesh strainer, then set aside to drain.
  2. Sauté the aromatics: Heat the olive oil in your pot over medium heat. Add the chopped onion and cook until translucent, about 5 minutes. Stir in the minced garlic and cook for another 1 minute until fragrant.
  3. Add the mushrooms: Toss in the sliced mushrooms and sauté until they release their moisture and begin to brown, about 7-8 minutes. This step builds the soup’s deep flavor.
  4. Incorporate vegetables: Add the diced carrots and celery, stirring to combine. Cook for another 5 minutes to soften the vegetables slightly.
  5. Add barley and broth: Pour in the rinsed barley, vegetable broth, dried thyme, and bay leaf. Stir everything together and bring to a boil.
  6. Simmer the soup: Reduce the heat to low, cover the pot, and let the soup simmer gently for 45-50 minutes, or until the barley is tender and the vegetables are cooked through.
  7. Season to taste: Remove the bay leaf, then add salt, pepper, and a splash of soy sauce or tamari if using. Adjust seasoning according to your preference.
  8. Serve and garnish: Ladle the soup into bowls and sprinkle with freshly chopped parsley for a burst of color and freshness.

Tips & Variations

“For an even heartier soup, add diced potatoes or parsnips along with the carrots and celery.”

To save time, you can use quick-cooking barley, but adjust the simmering time accordingly to avoid overcooking. If you prefer a creamier texture, stir in some coconut milk or cashew cream just before serving.

Experiment with mushrooms like shiitake or portobello for a richer flavor. Adding a splash of balsamic vinegar at the end can also elevate the earthy notes beautifully.

For a spicy kick, sprinkle in some crushed red pepper flakes or a dash of smoked paprika.
