If you’re craving a soup that’s delicious and healthy, mushroom barley soup is a fantastic option. Best of all, you likely already have most of the ingredients in your pantry. Veggies like carrots and celery are crisped in olive oil and then simmered with broth and barley for a supremely tasty soup that’ll warm you up on a winter evening. Here’s how to make it.

Ingredients for Mushroom Barley Soup

  • Olive oil: In addition to using olive oil to soften the vegetables, we like drizzling the finished product with a little oil, too; it intensifies the flavors of this soup.
  • Vegetables: We use a combination of onion, carrot, celery and portobello mushrooms, but this soup is very versatile so feel free to swap any of these out for the veggie of your choice.
  • Seasonings: A simple blend of garlic, salt, dried thyme and pepper is all you need to season this soup.
  • Vegetable broth: Be sure to use reduced-sodium vegetable broth so you can control the salt content.
  • Pearl barley: Pearl barley is rich in beneficial nutrients; it’s particularly high in fiber.
  • Fresh parsley: Parsley helps brighten and balance all the flavors of mushroom barley soup.
