How to Make Lemon Lentil Soup

Ingredients Youโ€™ll Need

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 (about 5 tablespoons)
1 teaspoon lemon zest
Optional: spinach or kale
To top: parsley or cilantro

Step-by-Step Directions

Heat the oil in a large stock pot over medium heat. Add the onion, celery, and carrots. Cook, stirring frequently, until the vegetables are soft and the onions are translucent, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.

Pour the vegetable stock over the vegetables, then add the red lentils, bay leaves, turmeric, and cumin. Stir well. Turn the heat up to medium-high to bring the soup to a boil. Then reduce the heat to medium-low to simmer. Cover and simmer for 12-15 minutes until the lentils are soft.

Remove the lid and stir in the lemon juice, lemon zest, salt, and pepper. Transfer 2 cups of soup to a blender. Blend on high until smooth, then pour it back into the soup and stir to combine. You can also use an immersion blender to partially blend the soup to your desired consistency.

Add the spinach, if using, and cook for 2-3 minutes to wilt. Taste and add more salt and pepper if needed. Serve with fresh cracked black pepper, cilantro, or parsley.

How to Serve Lemon Lentil Soup

Serve this soup warm in a bowl. You can add a sprinkle of fresh herbs like parsley or cilantro on top for extra flavor. Enjoy it with a slice of crusty bread or a side salad for a complete meal.

How to Store Lemon Lentil Soup

Store leftover soup in an airtight container in the refrigerator for up to 5 days. You can also freeze it for up to 3 months. Let the soup cool completely before transferring it to a freezer-safe container. Thaw it overnight in the fridge when you are ready to eat it again.

Tips for the Best Lemon Lentil Soup

For the best flavor, use fresh ingredients. Adjust the seasoning at the end to suit your taste. If you love a creamy texture, feel free to blend more of the soup until it reaches your desired consistency. Adding greens like spinach or kale not only boosts nutrition but also adds color and freshness.

Recipe Variations

You can easily customize this soup by adding other vegetables such as bell peppers or zucchini. If you like a bit of heat, add a pinch of red pepper flakes. For a non-vegetarian option, consider adding some diced chicken or turkey.
