Ingredients

For the Soup Base
- 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)
For the Broth
- 6 cups vegetable stock
- 1 1/2 cups red lentils
- 2 bay leaves
- 1/2 teaspoon turmeric
- 1 teaspoon cumin
Seasoning and Finishing Touches
- 1/2 teaspoon black pepper
- 1 teaspoon kosher salt
- Juice from 1 lemon (about 5 tablespoons)
- 1 teaspoon lemon zest
- Optional: spinach or kale
- To top: parsley or cilantro
How to Make Lemon Lentil Soup
Step 1: Sauté Vegetables
Heat the oil in a large stock pot over medium heat. Add the onion, celery, and carrots. Cook while stirring frequently until the vegetables soften and the onions become translucent, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.
Step 2: Add Stock and Lentils
Pour the vegetable stock over the sautéed vegetables. Then add the red lentils, bay leaves, turmeric, and cumin. Stir well to combine. Increase heat to medium-high to bring the soup to a boil. Once boiling, reduce heat to medium-low to simmer. Cover and let it simmer for 12-15 minutes until lentils are soft.
Step 3: Finish with Lemon Flavors
Remove the lid from the pot. Stir in the lemon juice, lemon zest, salt, and pepper.
Step 4: Blend for Creaminess
Transfer 2 cups of soup to a blender. Blend on high until smooth. Pour it back into the pot and stir to combine. Alternatively, use an immersion blender to partially blend to your desired consistency.
Step 5: Add Greens (Optional)
If using spinach or kale, add it now. Cook for an additional 2-3 minutes until wilted. Taste soup for seasoning; adjust salt and pepper as needed. Serve warm topped with fresh cracked black pepper and either cilantro or parsley.
Now you’re ready to enjoy a delicious bowl of Lemon Lentil Soup!

Common Mistakes to Avoid
Making lemon lentil soup can be simple, but there are common pitfalls to watch out for. Here are some mistakes to avoid for the best results:
- Skipping the sauté step: Not sautéing the vegetables can lead to a bland flavor. Always cook your onions, celery, and carrots until soft before adding other ingredients.
- Overcooking the lentils: Lentils can become mushy if cooked too long. Keep an eye on them during simmering; they should be tender but not falling apart.
- Not seasoning adequately: Failing to season properly can leave your soup underwhelming. Taste throughout the cooking process and adjust salt, pepper, and spices as needed.
- Ignoring lemon juice timing: Adding lemon juice too early can diminish its flavor. Incorporate it at the end of cooking for a fresh, zesty taste.
