Recipe FAQs

Do I need to cook pearl barley before adding to soup?

No, pearl barley can be added directly to the soup. It will cook and soften during the 35-40 minute simmer time, absorbing flavors and thickening the broth naturally.

Can I use other types of mushrooms?

Absolutely. While cremini or button mushrooms work well, you can also use shiitake for extra umami, porcini for deeper earthiness, or a mix of wild mushrooms for more complex flavor.

Is this soup freezer-friendly?

Yes, this soup freezes beautifully. Cool completely before transferring to airtight containers. It will keep for up to 3 months in the freezer. Note that barley may continue absorbing liquid, so you may need to add extra broth when reheating.

How can I add more protein to this soup?

You can stir in canned white beans during the last 10 minutes of cooking, add diced tofu, or serve with crusty bread and cheese. For non-vegetarian versions, shredded chicken or pancetta work well.

Why does the soup taste better the next day?

As the soup rests, the barley continues to absorb liquid and flavors meld together. The herbs and vegetables have more time to infuse the broth, creating a deeper, more harmonious taste.

Can I make this in a slow cooker?

Sauté the vegetables first in a pan, then transfer everything to your slow cooker. Cook on low for 6-7 hours or on high for 3-4 hours until the barley is tender. You may need to reduce the broth slightly as slow cookers retain more moisture.
