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

I start by heating the oil in a large stockpot over medium heat. I add the diced onion, chopped celery, and sliced carrots, then cook them for about 3 to 4 minutes while stirring until the vegetables begin to soften.

Next, I add the minced garlic and cook it for about a minute until it becomes fragrant.

I pour in the vegetable stock and add the red lentils, bay leaves, turmeric, and cumin. I stir everything together so the flavors combine well.

I bring the soup to a gentle boil, then reduce the heat to medium-low, cover the pot, and let it simmer for about 12 to 15 minutes until the lentils are soft and tender.

Once the lentils are cooked, I stir in the lemon juice, lemon zest, salt, and black pepper.

If I want a creamier texture, I blend about two cups of the soup until smooth and then return it to the pot. Sometimes I also use an immersion blender directly in the pot for convenience.

If I decide to add spinach or kale, I stir it in and let it cook for another 2 to 3 minutes until the greens are wilted.

I serve the soup hot and finish it with fresh parsley or cilantro and an extra sprinkle of black pepper.

Variations

I sometimes adjust this soup depending on what I have available or the flavors I am craving.

One variation I enjoy is adding diced potatoes or sweet potatoes to make the soup heartier. I also like adding a pinch of smoked paprika or chili flakes when I want a slightly smoky or spicy flavor.

Sometimes I replace part of the vegetable stock with coconut milk for a creamier texture and a subtle richness. Another option I like is adding cooked quinoa or rice to make the soup even more filling.

Storage/Reheating

I store leftover soup in an airtight container in the refrigerator for up to 4 days. The lentils continue to absorb liquid as the soup sits, so the texture may thicken slightly.

When I reheat the soup, I usually add a small splash of water or vegetable broth to loosen it. I warm it gently on the stove over medium heat while stirring occasionally, or I reheat individual portions in the microwave.

This soup also freezes well. I freeze it in portion-sized containers for up to 3 months and thaw it overnight in the refrigerator before reheating.

FAQs

Can I use green or brown lentils instead of red lentils?

I can use green or brown lentils, but they take longer to cook and will not break down as much as red lentils. The soup will have a chunkier texture rather than the naturally creamy consistency that red lentils provide.

Is this soup vegan?

Yes, this soup is completely plant-based. I use vegetable stock and avoid any dairy ingredients, which makes it naturally vegan and also dairy-free.

Can I make this soup without blending it?

Yes, I can skip the blending step entirely. The soup will still be delicious, but it will have a slightly more textured consistency instead of being partially creamy.

What can I serve with lemon lentil soup?

I like serving this soup with crusty bread, warm pita, or a simple side salad. These additions make the meal more filling and complement the bright flavors of the soup.

Can I make this soup ahead of time?

Yes, I often make it ahead because the flavors develop even more as it sits. I simply store it in the refrigerator and reheat it when I am ready to serve.

Conclusion

I find lemon lentil soup to be one of the easiest and most satisfying soups to prepare. The combination of red lentils, vegetables, warm spices, and fresh lemon creates a comforting dish that still feels light and vibrant. I appreciate how quickly it comes together and how well it stores for later meals. Whether I prepare it for a weeknight dinner or meal prep for the week, this soup always delivers a nourishing and flavorful bowl.
