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
To top: parsley or cilantro
Directions
-
Heat oil in a large stock pot over medium heat. Add onion, celery, and carrots. Stir and cook until softened, about 3–4 minutes.
-
Add the minced garlic and cook for another minute until fragrant.
-
Pour in the vegetable stock. Add lentils, bay leaves, turmeric, and cumin. Stir well to combine.
-
Bring the soup to a boil, then reduce the heat to medium-low and cover. Simmer for 12–15 minutes, or until the lentils are tender.
-
Stir in the lemon juice, lemon zest, salt, and black pepper.
-
For a creamier texture, carefully blend about 2 cups of the soup until smooth and return it to the pot, or use an immersion blender directly in the pot.
-
If using spinach or kale, stir it in and cook for another 2–3 minutes until wilted.
-
Serve hot, topped with fresh parsley or cilantro and an extra sprinkle of black pepper if desired.

Storage/Reheating
Store leftover soup in an airtight container in the refrigerator for up to 4 days.
To freeze, let the soup cool completely and transfer it to freezer-safe containers. Freeze for up to 3 months.
Reheat on the stovetop over medium heat, stirring occasionally, until warmed through. You can also microwave individual portions in 1-minute intervals, stirring between each, until hot. If the soup thickens too much, add a splash of water or vegetable stock to reach your desired consistency.
