Recipe FAQs

Can I make this soup gluten-free?

Pearl barley contains gluten, but you can substitute with quinoa, buckwheat, or brown rice. Adjust cooking time accordingly as these grains cook faster than barley.

How long does this soup keep in the refrigerator?

This soup stores beautifully for 4-5 days in an airtight container. The barley continues to absorb liquid, so you may need to add more broth when reheating leftovers.

Can I freeze mushroom and barley soup?

Yes, freeze for up to 3 months. Note that the barley will continue softening after freezing. For best texture, slightly undercook the barley if planning to freeze.

What type of mushrooms work best?

Cremini or button mushrooms are ideal for their earthy flavor and meaty texture. You can also use shiitake for extra umami or a mix of wild mushrooms for deeper flavor.

Can I add protein to this soup?

Diced potatoes, kale, or white beans make excellent additions. Add potatoes with the barley, or stir in kale during the last 15 minutes of simmering.

Why add lemon juice at the end?

Lemon juice brightens the earthy flavors and balances the richness. It's optional but recommended, especially if the soup tastes heavy or needs a fresh lift.
