Ingredients You’ll Need
What makes this Mushroom Barley Soup Recipe so delightful is how simple, wholesome ingredients come together to create a rich and vibrant dish. Each element plays a vital role—from the nutty barley and meaty mushrooms to the aromatic herbs and fresh vegetables that add layers of texture and color.

- Vegetable broth: Builds a savory, comforting liquid base that carries all the flavors.
- Dried thyme: Adds aromatic, slightly minty notes.

How to Make Mushroom Barley Soup Recipe
Step 1: Sauté the Aromatics
Start by heating the olive oil in a large pot over medium heat. Add the diced onion, minced garlic, sliced carrots, and chopped celery. Cook everything for about five minutes until the vegetables have softened just a bit and the onion turns translucent. This step builds the essential flavor base that your soup will develop from.
Step 2: Add and Brown the Mushrooms
Next up, toss in the sliced mushrooms. Give them some time to cook down until they’re softened and lightly browned. This step enhances their deep, earthy flavor and adds a lovely texture that’s key to this Mushroom Barley Soup Recipe.
Step 3: Stir in Barley and Seasonings
Now it’s time to add the pearl barley, vegetable broth, dried thyme, bay leaf, and a pinch of salt and pepper. Stir everything together to combine, making sure the barley is well distributed. This is the heart of the broth that will carry all your flavors throughout cooking.
Step 4: Simmer to Perfection
Bring the soup to a boil, then reduce the heat and let it simmer uncovered for 40 to 45 minutes. During this time, the barley will cook until tender and the flavors will harmonize beautifully. The aroma filling your kitchen at this step will be irresistible!
Step 5: Final Seasoning Adjustments
Once the barley is tender and the soup has thickened just right, remove the bay leaf. Taste the soup and adjust the seasoning with more salt or pepper if needed. This tasting step ensures your soup pops with flavor and is perfectly balanced.
Step 6: Serve it Up!
Ladle your hearty mushroom barley soup into bowls and garnish generously with fresh parsley for a pop of color and brightness. It’s best enjoyed hot, perhaps with a side of crusty bread to soak up all that delicious broth. Yum!

FAQs
Can I use other grains instead of pearl barley?
Absolutely! While pearl barley gives a unique chewy texture, you can substitute with farro, brown rice, or even quinoa. Just keep in mind that cooking times and textures will vary slightly.
Is this Mushroom Barley Soup Recipe vegetarian or vegan?
Yes, it’s completely vegetarian and vegan as long as you use vegetable broth. This makes it suitable for many dietary preferences while still being rich and satisfying.
Can I add protein to this soup?
Definitely! For extra protein, consider adding cooked beans like cannellini or chickpeas, or topping the soup with a dollop of Greek yogurt or shredded cheese, depending on your preferences.
How thick or soupy should the consistency be?
This soup is beautifully balanced—not too thick or too thin. The barley thickens it up a bit while the broth keeps it spoonable and cozy. Feel free to adjust broth levels to your liking during cooking.
What’s the best way to clean mushrooms for this recipe?
Quickly wipe mushrooms with a damp paper towel or use a soft brush to remove dirt. Avoid soaking them in water as mushrooms are porous and can become soggy, which affects the texture and flavor in your soup.
