Ingredients:
- 2 tbsp unsalted butter or olive oil
- 1 medium yellow onion, diced
- 2 large carrots, sliced into rounds
- 2 stalks celery, chopped
- 3 cloves garlic, minced
- 3/4 cup pearl barley, rinsed
- 2 medium Yukon Gold potatoes, cubed into 1/2 inch pieces
- 1 tbsp tomato paste
- 1 tsp dried thyme
- 1 bay leaf
- 8 cups low-sodium vegetable broth
- 2 cups chopped kale or baby spinach
- 1 tbsp fresh lemon juice
- salt to taste
- black pepper to taste
Instructions:
- Heat the butter or oil over medium heat. Add the onion, carrots, and celery. Sauté for 6–8 minutes until the onions are translucent and the vegetables have softened.
- Stir in the garlic and tomato paste, cooking for another 60 seconds until the paste turns a deep mahogany-colored hue.
- Stir in the rinsed pearl barley, cubed potatoes, thyme, and the bay leaf. Pour in the vegetable broth.
- Increase heat to bring the soup to a gentle boil, then immediately reduce to low. Cover with a lid and simmer for 30–35 minutes until barley and potatoes are tender.
- Remove the bay leaf. Stir in the chopped kale or spinach and let it wilt for 2 minutes from the residual heat.
- Stir in the lemon juice and season with salt and pepper to taste.
