Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1–2 tablespoons olive oil or avocado oil
3 large carrots, peeled and sliced
2 stalks celery, chopped
1 medium yellow onion, diced
4 cloves garlic, minced
6 cups vegetable stock
1 1/2 cups red lentils
2 bay leaves
1/2 teaspoon turmeric
1 teaspoon cumin
1/2 teaspoon black pepper
1 teaspoon kosher salt
juice from 1 lemon (approximately 5 tablespoons)
1 teaspoon lemon zest
optional spinach or kale
fresh parsley or cilantro, for garnish
Directions
Heat the oil in a large stockpot over medium heat. Add the diced onion, chopped celery, and sliced carrots. Cook while stirring occasionally until the vegetables soften, about 3 to 4 minutes.
Add the minced garlic and cook for another minute until fragrant.
Pour in the vegetable stock, then add the red lentils, bay leaves, turmeric, and cumin. Stir everything together until well combined.
Bring the soup to a boil. Reduce the heat to medium-low, cover the pot, and let it simmer for 12 to 15 minutes until the lentils are tender.
Stir in the lemon juice, lemon zest, salt, and black pepper.
For a creamier consistency, blend about two cups of the soup until smooth and return it to the pot. Alternatively, use an immersion blender directly in the pot for a partially blended texture.
If using spinach or kale, stir it into the soup and cook for another 2 to 3 minutes until the greens are wilted.
Serve the soup hot and garnish with fresh parsley or cilantro and additional black pepper if desired.
