Mushroom Barley Soup from Scratch
Ingredients
- 2 tbsp olive oil
- 1 cup dried mushrooms soaked in hot water
- 8 oz fresh mushrooms sliced
- 1 cup barley hulled or pearl
- 1 large onion diced
- 2 cloves garlic minced
- 4 cups vegetable broth
- 1 tsp salt to taste
- 1/2 tsp black pepper freshly ground
- 2 tbsp soy sauce
- 1 tbsp fresh thyme chopped
- 1 tbsp fresh parsley chopped
Instructions
- Heat olive oil in a large pot over medium heat. Add diced onion and sauté until translucent, about 5 minutes. Stir in minced garlic, cooking until fragrant, about 1 minute, ensuring it doesn't burn.
- Add sliced fresh mushrooms to the pot over medium heat. Cook for 8-10 minutes, stirring occasionally. Watch for them to release moisture and develop a golden brown color, indicating they are caramelizing. Their earthy aroma will become more pronounced as they cook, signaling readiness.
- Gently stir in the soaked dried mushrooms, including their soaking liquid, while carefully avoiding any sediment at the bottom. Allow the mixture to simmer over medium heat for 5 minutes, enhancing the soup's depth. The mushrooms should be tender, and the liquid should integrate smoothly, adding a rich aroma.
- Add the barley to the pot, stirring thoroughly to coat it with the mushroom mixture. Cook over medium heat for about 5 minutes, allowing the barley to absorb the flavors and develop a chewy texture. Stir occasionally to prevent sticking and ensure even cooking.
- Pour in vegetable broth and bring the mixture to a boil. Reduce heat to low, cover, and simmer for 40-50 minutes, or until barley is tender and has absorbed the broth's flavors.
- Add salt, freshly ground black pepper, and soy sauce to the soup, stirring well to combine. Taste and adjust the seasoning as needed, remembering that soy sauce contributes a savory note. Allow the soup to simmer for an additional 5 minutes, ensuring the flavors meld together harmoniously.
- Stir in fresh thyme and parsley just before serving. This adds a bright, fresh aroma that complements the earthy soup.
- If the soup becomes overly thick, gradually add more vegetable broth or water, stirring continuously to ensure even distribution. Adjust the consistency to your preference, keeping the soup at a gentle simmer. Monitor the texture closely, and taste occasionally to maintain the balance of flavors, ensuring the soup remains smooth and cohesive.
- Before serving, enhance the soup's presentation by drizzling a small amount of olive oil over the top. This will add a subtle sheen and a hint of richness. Ensure the soup is hot, as the olive oil will gently meld with the surface, creating an inviting appearance.
- Ladle the hot soup into bowls, appreciating the chewy texture of the barley and the tender mushrooms immersed in the savory broth. Notice the inviting aroma that fills the air, enhancing the comforting experience. Serve immediately to enjoy the warmth and depth of flavors, ensuring a satisfying conclusion to your meal.
Notes
Pro Tips
- Soak dried mushrooms in hot water to rehydrate them and release their concentrated flavors into the soaking liquid, which can be added to the soup for extra depth.
- Opt for a heavy-bottomed pot when making this soup. Its thick base ensures even heat distribution, reducing the risk of scorching during simmering. This is particularly important for maintaining the soup’s texture and preventing any burnt flavors from developing.
- To adjust the thickness of your mushroom barley soup, slowly incorporate additional broth or water. This method allows you to reach the preferred consistency while maintaining the soup’s depth of flavor, as the gradual addition prevents excessive dilution.
- To deepen the savory notes in your mushroom barley soup, incorporate a small amount of soy sauce or tamari. These ingredients boost the umami quality, complementing the mushrooms and barley without overshadowing their natural flavors, creating a well-rounded dish.
- To ensure the barley reaches the desired tenderness, extend the simmering time if needed. This step is crucial to avoid a gritty texture, allowing the grains to fully absorb the broth and soften properly, enhancing the soup’s overall consistency.
Variations
- For a budget-friendly version, replace dried mushrooms with more fresh mushrooms, which are often less expensive and still provide a hearty texture.
- To make it gluten-free, substitute the barley with quinoa or rice, adjusting the cooking time as needed to ensure the grains are tender.
- Incorporate seasonal vegetables like butternut squash or sweet potatoes for a fall-inspired twist, adding sweetness and color to the soup.
- Add a Mediterranean flair by including a pinch of smoked paprika and a handful of chopped spinach, enhancing the soup with smoky and fresh notes.
Storage
To store leftover mushroom barley soup, transfer it to shallow, airtight containers and place them in the refrigerator within two hours of cooking. The soup will remain fresh for up to four days. For extended storage, freeze the soup for up to three months. Be aware that freezing can slightly change the barley’s texture, making it softer when reheated. Thaw the soup overnight in the refrigerator before reheating to 165 F (74 C) for safe consumption.
How to Reheat
To reheat, place the soup in a pot over medium heat, stirring occasionally until it reaches an internal temperature of 165 F (74 C). Alternatively, microwave individual portions in a microwave-safe bowl, covered, on medium power, stirring every minute until hot. Add a splash of broth if the soup thickens too much during reheating.

FAQ
Can I use pearl barley instead of hulled barley?
Yes, you can use pearl barley, which cooks faster than hulled barley. Adjust the cooking time accordingly, as pearl barley typically requires about 20-25 minutes less to become tender. This substitution will slightly change the texture, making it less chewy.
What can I substitute for dried mushrooms?
If dried mushrooms are unavailable, increase the quantity of fresh mushrooms. While the flavor won’t be as concentrated, fresh mushrooms still provide a good texture and taste. Consider adding a bit of soy sauce to enhance the umami flavor profile.
How do I prevent the soup from becoming too thick?
To prevent the soup from thickening too much, monitor the liquid level as it simmers. If it reduces significantly, add more broth or water gradually. Stir occasionally to ensure even cooking and prevent ingredients from sticking to the bottom of the pot.
Is this soup suitable for vegetarians?
Yes, this mushroom barley soup is vegetarian, as it uses vegetable broth and excludes any meat products. To ensure the dish remains vegetarian, check that all ingredients, such as soy sauce, are free from animal-derived additives, like fish extracts. Additionally, you can adjust the seasonings according to your preference, adding more herbs or spices if desired. This flexibility allows you to tailor the soup to your taste while keeping it vegetarian.
Can I add meat to this soup?
Certainly, incorporating cooked chicken or beef can make the soup more substantial. To do this, add shredded or diced meat during the final 10 minutes of cooking. This allows the meat to warm through without becoming tough. Remember to adjust the seasoning to suit the added meat, ensuring the flavors meld well. This addition can transform the soup into a more filling meal, perfect for those seeking a heartier dish.
The key to this mushroom barley soup is allowing the barley to cook directly in the broth, absorbing flavors and achieving the perfect chewy texture. This method ensures a mix of textures and aromas, resulting in a comforting bowl of soup.
