Ingredients for One-Pot Rustic Wild Mushroom and Barley Soup

Instructions

Heat olive oil in a large heavy-bottomed pot or slow cooker insert over medium heat (use sauté function if available on slow cooker).
Sauté onion and garlic for 3-4 minutes until softened and aromatic.
Add sliced mushrooms, carrots, and celery; cook for 8-10 minutes, stirring occasionally, until mushrooms release moisture and soften.
Stir in rinsed pearl barley, dried thyme, dried rosemary, and bay leaves.
Pour in vegetable broth and stir to combine. Season with salt and freshly ground black pepper to taste.
For stovetop: Bring to a boil, then reduce heat to low. Cover and simmer for 45-60 minutes until barley is tender and soup thickens. Stir occasionally to prevent sticking.
For slow cooker: Cover and cook on low for 4 hours until barley is tender and flavors meld.
Remove bay leaves before serving.
Serve hot garnished with fresh parsley.
Enjoy with crusty gluten-free bread or a light side salad.
