This simple vegan lentil soup recipe comes together quickly with mostly pantry ingredients. Be sure to have your ingredients prepped and ready before you start cooking! Recipe yields four large bowls of soup or six more modest servings.
- ¼ cup olive oil extra virgin
- 1 medium yellow or white onion chopped
- 2 carrots peeled and chopped
- 4 garlic cloves pressed or minced
- 2 teaspoons ground cumin
- 1 teaspoon curry powder
- ½ teaspoon dried thyme
- 1 large can 28 ounces diced tomatoes drained
- 1 cup brown or green lentils picked over and rinsed
- 4 cups vegetable broth
- 2 cups water
- 1 teaspoon salt more to taste
- 1 Pinch red pepper flakes
- Freshly ground black pepper
- 1 cup chopped fresh collard greens or kale tough ribs removed
- Juice of ½ to 1 medium lemon to taste
Warm the olive oil in a large soup pot over medium heat. One-fourth cup olive oil may seem like a lot, but it adds a lovely richness and heartiness to this nutritious soup.
Once the oil is shimmering, add the chopped onion and carrot and cook, stirring often, until the onion has softened and is turning golden brown, about 5 minutes. Add the garlic, cumin, curry powder and thyme. Cook until fragrant while stirring constantly, about 30 seconds. Pour in the drained diced tomatoes and cook for a few more minutes, stirring often, in order to enhance their flavour.
Pour in the lentils, broth and the water. Add 1 teaspoon salt and a pinch of red pepper flakes. Season generously with freshly ground black pepper. Raise heat and bring the mixture to a boil, then partially cover the pot and reduce heat to maintain a gentle simmer. Cook for 30 minutes, or until the lentils are tender but still hold their shape.
Transfer 2 cups of the soup to a blender. Securely fasten the lid, protect your hand from steam with a tea towel placed over the lid, and purée the soup until smooth. Pour the puréed soup back into the pot. (Or, use an immersion blender to blend a portion of the soup.)
Add the chopped greens and cook for 5 more minutes, or until the greens have softened to your liking. Remove the pot from the heat and stir in the juice of half of a lemon. Taste and season with more salt, pepper and/or lemon juice until the flavors really sing. Serve immediately. Leftovers will keep well for about 4 days in the refrigerator, or can be frozen for several months (just defrost before serving).
