  • Mushrooms: 1 oz (28 g) dried shiitake mushrooms and 8 oz (225 g) sliced white mushrooms
  • Grains: 3/4 cup (130 g) pearl barley, rinsed
  • Aromatics & Vegetables: 2 tbsp olive oil, 1 medium onion (diced), 2 medium carrots (diced), 2 celery stalks (diced), and 3 garlic cloves (minced)
  • Broth & Seasonings: 8 cups (2 L) low-sodium vegetable broth, 2 bay leaves, 1 tsp dried thyme, 1 tsp dried parsley, plus salt and freshly ground black pepper to taste
  • Garnish (optional): 2 tbsp chopped fresh parsley

Instructions

Step 1: Prepare the Shiitake Mushrooms
Place dried shiitake mushrooms in a heatproof bowl. Cover with 2 cups (480 ml) boiling water and let soak for 20 minutes. Drain, reserving the soaking liquid, and slice the mushrooms. Strain the soaking liquid through a fine sieve or cheesecloth to remove any grit.
Step 2: Sauté the Aromatics
In a large soup pot, heat olive oil over medium heat. Add the onion, carrots, and celery; sauté for 5 minutes until softened.
Step 3: Add Garlic
Add the minced garlic and cook for 1 minute until fragrant.
Step 4: Cook the Mushrooms
Stir in the fresh white mushrooms and the sliced soaked shiitake mushrooms. Cook for about 5 minutes, until the mushrooms begin to release their juices.
Step 5: Simmer the Soup
Add the pearl barley, the reserved mushroom soaking liquid, and the vegetable broth. Stir in the bay leaves, thyme, parsley, salt, and pepper.
Step 6: Cook until Tender
Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 50–60 minutes, stirring occasionally, until the barley is tender.
Step 7: Final Adjustments
Remove the bay leaves. Taste the broth and adjust the salt and pepper seasoning as needed.
Step 8: Serve
Ladle the soup into bowls and garnish with fresh parsley if desired. Serve hot.

Zusatztipps für die Zubereitung

Achte darauf, das Einweichwasser der Shiitake-Pilze gründlich durch ein feines Sieb oder ein Passiertuch zu filtern. Diese Flüssigkeit enthält zwar das volle Aroma der Pilze, kann aber auch feine Sand- oder Erdreste enthalten, die das Mundgefühl beeinträchtigen könnten. Wenn die Suppe beim Abkühlen zu stark eindickt, kannst du beim Aufwärmen einfach etwas mehr Brühe oder Wasser hinzufügen, um die gewünschte Konsistenz wiederherzustellen.

Varianten und Anpassungen

Für eine noch gehaltvollere Suppe kannst du zusammen mit dem Gemüse etwa eine Tasse gewürfelte Kartoffeln oder Pastinaken hinzufügen. Wer keine vegetarische Version benötigt, kann die Gemüsebrühe durch Hühnerbrühe ersetzen, was dem Gericht eine zusätzliche Tiefe verleiht. Achte beim Kauf der Brühe auf die Etiketten, falls du auf bestimmte Allergene wie Soja oder Nüsse achten musst.

Serviervorschläge

Serviere diese Suppe ganz klassisch mit einer Scheibe frischem Roggenbrot, um das authentische Deli-Erlebnis abzurunden. Die herbe Note des Brotes harmoniert hervorragend mit dem erdigen Geschmack der Pilze. Ein zusätzlicher Spritzer frischer Petersilie direkt vor dem Servieren sorgt nicht nur für eine optische Aufwertung, sondern bringt auch eine angenehme Frische in das Gericht.

Recipe FAQs

Can I use other types of mushrooms in this soup?

Yes, you can substitute or add cremini, portobello, or oyster mushrooms for variety. The dried shiitake mushrooms provide essential depth, so keep those if possible, but feel free to experiment with different fresh mushroom combinations.

How can I make this soup gluten-free?

Replace the pearl barley with wild rice, brown rice, or quinoa. Adjust cooking time accordingly—wild rice may take longer, while quinoa cooks faster, around 20-25 minutes.

Can I make this soup in advance?

Absolutely. This soup tastes even better the next day as flavors meld. Store in an airtight container in the refrigerator for up to 5 days. The barley will absorb liquid, so add extra broth when reheating.

What can I serve with mushroom barley soup?

Classic pairings include crusty rye bread, sourdough, or garlic bread. A simple green salad or grilled cheese sandwich also complements this hearty soup beautifully for a complete meal.

Can I freeze mushroom barley soup?

Yes, this soup freezes well for up to 3 months. Cool completely before transferring to freezer-safe containers. Note that the barley texture may soften slightly after freezing, but the flavor remains excellent.

How do I prevent the mushroom soaking liquid from being gritty?

Always strain the soaking liquid through a fine-mesh sieve lined with cheesecloth or a coffee filter. Dried mushrooms can contain sand and debris that settles at the bottom, so pour carefully and discard the last bit of liquid.
