Vegetable Lentil Soup Recipe
This vegetable lentil soup is an easy and hearty soup made with fresh vegetables and protein-rich lentils. Ground cumin adds warmth and a splash of red wine vinegar is the secret ingredient that makes it an outstanding soup recipe. Skip the cheese to make it dairy-free/vegan, and serve it with a crusty roll for a delicious weeknight meal. I've even got instructions on how to make it using your slow cooker!

- 2 Tablespoons extra-virgin olive oil
- 1 yellow onion, diced
- 3 celery stalks, chopped
- 3 medium carrots, chopped
- 3 garlic cloves, minced or finely chopped
- ½ teaspoon ground cumin
- 1 ½ teaspoons sea salt
- ½ teaspoon ground black pepper
- ½ Tablespoon fresh thyme leaves, finely chopped or ½ teaspoon dried thyme
- 6 cups vegetable stock
- 2 Tablespoons tomato paste
- 1 cup dried green lentils, rinsed in a colander
- 2 Tablespoons red wine vinegar
- 3 large pieces of kale (leaves only), chopped
- Freshly grated Parmesan cheese, for serving (optional)
Heat the olive oil in a large pot over medium heat. Add the onion, celery, carrots, garlic, cumin, salt, pepper, and thyme, and cook, stirring occasionally, for 10 minutes, until the vegetables are tender.
Add the vegetable stock, tomato paste, and rinsed lentils. Cover and bring to a boil. Reduce the heat and simmer for 25 to 30 minutes, until the lentils are softened and tender.
Add the kale leaves and cook for 5 minutes, or until wilted.
Remove from heat and add the red wine vinegar. Season to taste. Serve sprinkled with grated Parmesan cheese, if using.
- Storage: Cover soup and store it in the fridge for up to 4 days.
- How to reheat soup: You can heat the soup in the microwave or on the stovetop. To heat on the stovetop, place soup pot over medium-low heat for 15 minutes, until heated through, stirring frequently.
- How to freeze soup: Cool soup in the refrigerator, then transfer it to a freezer-safe container. I like to portion my soup into quart-sized freezer bags for easier thawing. To thaw, place in the refrigerator overnight, or place bag into a warm bowl of water for 30 minutes.
- Use green or brown lentils. If you use red lentils, you will need to cut the cooking time in half.
