# What You'll Need:

→ Mushrooms

01 - 1 ounce dried shiitake mushrooms
02 - 8 ounces white mushrooms, sliced

→ Grains

03 - 3/4 cup pearl barley, rinsed

→ Aromatics & Vegetables

04 - 2 tablespoons olive oil

10 - 2 bay leaves
11 - 1 teaspoon dried thyme
12 - 1 teaspoon dried parsley
13 - Salt and freshly ground black pepper to taste

→ Garnish

14 - 2 tablespoons fresh parsley, chopped

# How to Make It:

01 - Place dried shiitake mushrooms in a heatproof bowl and cover with 2 cups boiling water. Let soak for 20 minutes. Drain, reserving the soaking liquid, and slice the mushrooms. Strain the soaking liquid through a fine-mesh sieve or cheesecloth to remove sediment.
02 - Heat olive oil in a large soup pot over medium heat. Add diced onion, carrots, and celery. Sauté for 5 minutes until softened.
03 - Add minced garlic to the pot and cook for 1 minute until fragrant.
04 - Stir in fresh white mushrooms and rehydrated shiitake mushrooms. Cook for approximately 5 minutes until mushrooms begin releasing their juices.
05 - Add pearl barley, reserved mushroom soaking liquid, and vegetable broth to the pot. Stir in bay leaves, thyme, parsley, salt, and pepper.
06 - Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 50 to 60 minutes, stirring occasionally, until barley becomes tender.
07 - Remove bay leaves from the pot. Taste and adjust seasonings with salt and pepper as needed.
08 - Ladle soup into bowls and garnish with fresh chopped parsley. Serve immediately while hot.

# Expert Advice:

01 -
  • It's the kind of soup that tastes like it took all day but actually comes together in about ninety minutes, which is the best kind of kitchen magic.
  • Dried shiitakes give you this deep, almost meaty richness without any animal products, so vegetarians and meat-eaters alike will genuinely want seconds.
  • Your kitchen will smell incredible the moment you start rehydrating those mushrooms, and that aroma alone makes cooking feel like self-care.
02 -
  • Straining that mushroom soaking liquid through cheesecloth or a fine sieve is not optional—grit from dried mushrooms will make you feel like you're eating sand, and that's not the vibe.
  • Don't skip rinsing the barley before it goes in, because unrinsed barley will make your soup thick and starchy in a way that tastes more like paste than soup.
  • The soup gets noticeably thicker as it sits because the barley keeps absorbing liquid, so if you're reheating leftovers, add extra broth or water without hesitation.
03 -
  • If you can't find dried shiitakes, dried porcini mushrooms work beautifully in their place, though they're earthier and might require a slightly lighter hand with the salt.
  • Tear the rehydrated mushrooms instead of slicing them if you're not in the mood for precision—they'll break apart in the pot anyway, and rustic is often more forgiving than perfect.
