Mushroom and Barley Soup

The first time I made this soup, it was snowing so hard you could barely see across the street. I'd bought pearl barley on a whim months earlier, and there it sat, gathering dust in the back of the pantry. Something about those little pearls just whispered comfort food. Now it's become my go-to whenever the weather turns grey or someone needs a proper hug in a bowl.

Last winter, my roommate came home from a terrible day at work to find this bubbling away on the stove. She didn't even take her coat off, just stood there breathing in the thyme and mushrooms. We ate it standing up in the kitchen, both too hungry to bother with proper seating, and she told me it was exactly what she didn't know she needed.

Ingredients

• 2 tbsp olive oil: This creates the foundation for all those vegetable flavors to build upon
• 1 medium onion, finely chopped: Getting these nice and translucent first adds a subtle sweetness that balances the earthy mushrooms
• 2 cloves garlic, minced: Don't let it brown, just let it become fragrant in the hot oil
• 2 medium carrots, diced: They bring natural sweetness and keep their texture nicely through the long simmer
• 2 celery stalks, diced: The backbone of any good soup base, adding that essential aromatic depth
• 400 g mushrooms, sliced: Cremini give more flavor, but whatever you have on hand will still be delicious
• 1 tsp dried thyme: Earthy and woodsy, it pairs perfectly with mushrooms
• 1 tsp dried oregano: Adds a subtle Mediterranean warmth
• 120 g pearl barley, rinsed: Rinse it well until the water runs clear to remove excess starch
• 1.5 liters vegetable broth: Use a good quality one, since it makes up most of the soup's flavor
• 1 bay leaf: An aromatic secret weapon that gets removed at the end
• Salt and freshly ground black pepper: Taste and adjust at the very end since broth brands vary so much in saltiness
• 2 tbsp fresh parsley, chopped: Brings a bright pop of color and fresh flavor to finish
• 1 tbsp lemon juice: Just enough to wake up all the flavors without making it taste acidic

Instructions

Build your flavor base:

Heat the olive oil in a large pot over medium heat, add the onion, and cook for 3 minutes until it turns translucent and soft

Add the aromatic vegetables:

Stir in the garlic, carrots, and celery, then cook for 5 minutes, stirring occasionally until they begin to soften

Develop the mushroom flavor:

Add the sliced mushrooms and cook for 6-8 minutes, watching as they release their moisture and start to turn golden brown

Layer in the herbs:

Sprinkle in the thyme and oregano, stirring constantly so they become fragrant and coat everything evenly

Bring it all together:

Add the rinsed barley, vegetable broth, and bay leaf, stirring to combine everything

Let it simmer slowly:

Bring to a boil, then reduce heat to low and simmer uncovered for 35-40 minutes until the barley is tender and the soup has thickened slightly

Finish with bright notes:

Remove the bay leaf, then season to taste with salt, pepper, and lemon juice if you want that extra brightness

Serve it up:

Ladle into warm bowls and finish with a sprinkle of fresh parsley for that just-made feeling

My grandmother would always say a good soup needs time to get to know itself. Now I understand what she meant, watching this pot transform from separate ingredients into something that feels like it's always belonged together.

Make It Your Own

Sometimes I'll toss in diced potatoes or chopped kale during the last 15 minutes if I want something more substantial. The potatoes break down slightly and make the soup even creamier, while kale holds its texture and adds nutritional punch.

The Umami Secret

A tablespoon of soy sauce added with the broth creates an incredible depth of flavor that people can never quite put their finger on. It doesn't make the soup taste Asian, just more intensely savory and satisfying in that way that keeps you coming back for another spoonful.

Leftover Magic

This soup might actually be better on day two, once all the flavors have had time to really become friends overnight in the refrigerator. The barley continues to soften and the broth becomes richer, almost like a completely different but equally wonderful soup.

• Store in an airtight container for up to 4 days
• When reheating, add a splash of water or broth since the barley will have absorbed more liquid
• Freeze individual portions for those nights when cooking feels impossible

There's something deeply restorative about a bowl of this soup, like it understands exactly what you need before you do. Hope it brings you as much comfort as it has brought me.

Recipe Questions & Answers

→ Do I need to soak pearl barley before cooking?

No soaking required. Pearl barley cooks directly in the broth, absorbing liquid and flavors as it simmers. Just rinse thoroughly before adding to the pot.

→ Can I use other types of mushrooms?

Absolutely. Cremini, button, shiitake, or portobello all work beautifully. Mixed wild mushrooms add extra depth and earthiness to the broth.

→ How long does this soup keep in the refrigerator?

Stores well for 4-5 days in an airtight container. The barley continues absorbing liquid, so you may need to add broth when reheating leftovers.

→ Is this soup gluten-free?

Pearl barley contains gluten. For a gluten-free version, substitute with quinoa, rice, or buckwheat, and ensure your vegetable broth is certified gluten-free.

→ Can I freeze this soup?

Yes, freeze for up to 3 months. The barley may soften slightly upon thawing, but the flavors remain delicious. Thaw overnight in the refrigerator before reheating.

→ What can I add for extra protein?

Stir in white beans, lentils, or cubed tofu during the last 15 minutes of cooking. For non-vegetarian versions, shredded chicken works beautifully.
