Ingredients

  • 1 cup pearl barley, rinsed
  • 8 oz cremini mushrooms, sliced
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 3 medium carrots, diced
  • 2 stalks celery, diced
  • 6 cups vegetable broth
  • 2 tbsp olive oil
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 1 bay leaf
  • Salt and black pepper, to taste
  • Fresh parsley, chopped, for garnish

Equipment

  • Large soup pot or Dutch oven
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Wooden spoon or spatula
  • Ladle, for serving
  • Fine mesh strainer, to rinse barley

Instructions

  1. Prepare the barley: Rinse the pearl barley under cold running water using a fine mesh strainer. Set aside to drain.
  2. Sauté the vegetables: Heat the olive oil in a large soup pot over medium heat. Add the chopped onion, carrots, and celery. Cook, stirring occasionally, until the vegetables start to soften and the onions become translucent, about 5-7 minutes.
  3. Add garlic and mushrooms: Stir in the minced garlic and sliced mushrooms. Cook for another 5 minutes until the mushrooms release their moisture and start browning.
  4. Add herbs and barley: Sprinkle in the dried thyme and rosemary. Stir to combine, then add the rinsed barley, stirring to coat it well with the vegetable mixture.
  5. Pour in broth and bay leaf: Add the vegetable broth and bay leaf to the pot. Increase the heat to bring the soup to a boil.
  6. Simmer the soup: Once boiling, reduce the heat to low and cover the pot. Let the soup simmer gently for 40-50 minutes, or until the barley is tender and the flavors are well developed. Stir occasionally to prevent sticking, and add water or broth if needed.
  7. Season to taste: Remove the bay leaf. Season the soup with salt and black pepper according to your preference. Give it a final stir.
  8. Serve and garnish: Ladle the hot soup into bowls and garnish with freshly chopped parsley. Enjoy!

Tips & Variations

To deepen the umami flavor, try adding a splash of soy sauce or tamari towards the end of cooking.

Feel free to experiment with different mushroom varieties like shiitake or portobello for a richer taste. You can also throw in other vegetables such as diced potatoes, parsnips, or kale for extra nutrition and texture.

If you prefer a thicker soup, you can mash some of the barley and vegetables with a potato masher or blend a portion of the soup and then mix it back in. For a gluten-free option, substitute pearl barley with hulled barley or quinoa, but note the cooking times may vary.

To make this recipe even more filling, add cooked beans or lentils in the last ten minutes of cooking. This soup freezes well, so consider making a big batch to enjoy later.
