Mushroom Barley Soup
Ingredients
&w=3840&q=75){kind=small}
- 1 ounces dried porcini mushrooms
- 2 cups water – boiling (for soaking porcini)
- 3/4 cups pearl barley – rinsed
- 16 ounces cremini mushrooms – sliced (~25 medium cremini mushrooms)
- 3 tablespoons olive oil
- 1 yellow onion – chopped
- 2 carrots – diced
- 2 stalks celery – diced
- 3 cloves garlic – minced
- 1 teaspoons dried thyme
- 64 ounces vegetable broth
- 2 leaves bay leaves
- 1 1/2 teaspoons kosher salt
- 1/2 teaspoons black pepper – freshly ground
- 1/4 cups fresh dill – chopped
Instructions
1. Place the dried porcini in a heatproof bowl and pour the boiling water over them; soak until softened, 20–30 minutes. Rinse the pearl barley in a fine-mesh sieve until the water runs mostly clear; drain.
2. Heat 2 tablespoons of the olive oil in a large pot over medium-high heat. Add the sliced cremini mushrooms and cook, stirring occasionally, until deeply browned and most liquid has evaporated, 8–10 minutes. Transfer mushrooms to a bowl.
3. Add the remaining 1 tablespoon olive oil to the pot. Add the chopped onion, diced carrots, and diced celery; season lightly with kosher salt and cook over medium heat, stirring, until softened and translucent, 6–8 minutes.
4. Stir in the minced garlic and dried thyme and cook until fragrant, about 1 minute.
5. Return the browned mushrooms to the pot. Add the rinsed barley and cook, stirring, to lightly toast the grains, 1–2 minutes.
6. Lift the soaked porcini from their liquid; finely chop them. Strain the soaking liquid through a fine sieve or coffee filter to remove grit. Add the chopped porcini, strained soaking liquid, vegetable broth, and bay leaves to the pot. Stir in about 1 teaspoon kosher salt and the black pepper. Bring to a simmer.
7. Partially cover and simmer gently, stirring occasionally, until the barley is tender but pleasantly chewy and the soup has a rich body, 45–55 minutes. If needed, skim any foam. Taste and season with the remaining kosher salt and more black pepper as needed.
8. Remove and discard the bay leaves. Stir in the chopped dill. Let the soup rest off heat for 10 minutes to thicken slightly, then ladle into bowls and serve.
Mushroom Barley Soup is a hearty, earthy bowl built on the nutty chew of pearl barley and the deep savor of mushrooms. The combination yields a broth with remarkable body, layered with sweetness from onions, carrots, and celery, and lifted by fragrant herbs. Fresh dill at the finish brightens the stew-like richness, making it both comforting and invigorating.
Rooted in Ashkenazi home cooking across Eastern Europe, the soup draws on practical pantry habits: foraged mushrooms (often dried) for umami and barley as a staple grain. It traveled with Jewish communities, becoming a deli standard in North America and a winter favorite in many households. Variations range from meatless weekday pots to beef-enriched holiday versions, all sharing the same mushroom-barley backbone that defines the dish’s character.
