Ingredients

  • 4 tbsp Extra virgin olive oil
  • 1 lb Cremini mushrooms cleaned and sliced
  • 1/2 lb Shitake mushrooms cleaned and sliced
  • 2 ribs Celery diced, plus leaves
  • 3 medium Carrots diced
  • 4 cloves Garlic minced
  • 1 cup Dry white wine
  • 10 cups Vegetable stock
  • 6 sprigs Fresh thyme
  • 2 large Bay leaves
  • 1 cup Pearl barley
  • 1/2 tsp Kosher salt or more to taste
  • 1/2 tsp Black pepper or more to taste

Instructions

  • Heat oil in a large Dutch oven over medium-high heat. Add mushrooms and cook until they start to release their water and brown, 10-15 minutes.
    4 tbsp Extra virgin olive oil, 1 lb Cremini mushrooms, 1/2 lb Shitake mushrooms
  • Add the celery, carrots, and onions and cook until softened, about 10 minutes. Add garlic and cook another minute.
    2 ribs Celery, 3 medium Carrots, 4 cloves Garlic
  • Add the white wine, bring to a boil, and reduce for 2 minutes while scraping the bottom of the pot to remove all the flavor bits. Add the vegetable stock, bay leaves, and thyme. Bring to a boil, reduce the heat to a simmer.
    1 cup Dry white wine, 10 cups Vegetable stock, 6 sprigs Fresh thyme, 2 large Bay leaves
  • Add the pearl barley, kosher salt, and black pepper. Simmer for 45-60 minutes, stirring occasionally to avoid sticking, until the barley is tender. Remove the bay leaves and thyme stems, season to taste with salt and pepper and serve.
    1 cup Pearl barley, 1/2 tsp Kosher salt, 1/2 tsp Black pepper

Notes

  • Brown the mushrooms well. Pale mushrooms will render pale soup and less flavor.
  • If the soup thickens too much after sitting, add a splash of broth.
  • For a richer, creamy version, add a splash of cream at the end.
  • For extra umami, a teaspoon of Worcestershire sauce works beautifully (omit if vegetarian). Or we like to add Trader Joe’s Mushroom and Company Multipurpose Umami seasoning blend.
