Why You’ll Love Best Lentil Soup Recipe Recipe
This lentil soup combines simple pantry staples with fresh vegetables to create a flavorful meal without complicated preparation. Lentils make the soup filling and hearty, while cumin, curry powder, thyme, garlic, and black pepper give the broth plenty of depth.
The texture is another highlight. Instead of adding cream, a portion of the cooked soup is blended and stirred back into the pot. This thickens the broth while preserving the rustic texture of the remaining lentils and vegetables.
It is also an excellent make-ahead recipe. The flavors continue to develop after refrigeration, and the soup freezes well, making it convenient for batch cooking and future meals.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
- ¼ cup extra-virgin olive oil
- 1 medium yellow or white onion, chopped
- 2 carrots, peeled and chopped
- 4 garlic cloves, minced or pressed
- 2 teaspoons ground cumin
- 1 teaspoon curry powder
- ½ teaspoon dried thyme
- 1 large (28-ounce) can diced tomatoes, lightly drained
- 1 cup brown or green lentils, rinsed and checked for debris
- 4 cups vegetable broth
- 2 cups water
- 1 teaspoon salt, plus more as needed
- A pinch of red pepper flakes
- Freshly ground black pepper, to taste
- 1 cup chopped kale or collard greens, with tough stems removed
- 1 to 2 tablespoons fresh lemon juice, to taste
Directions
- Heat the olive oil in a large soup pot or Dutch oven over medium heat. Once the oil is hot, add the onion and carrots. Cook for about 5 minutes, stirring occasionally, until the onion becomes tender and translucent.
- Add the minced garlic, cumin, curry powder, and dried thyme. Stir continuously for about 30 seconds, just until the spices become fragrant.
- Add the diced tomatoes and cook for another 2 to 3 minutes. Stir occasionally so the tomatoes combine with the aromatics and spices.
- Stir in the lentils, vegetable broth, and water. Add the salt, red pepper flakes, and a generous amount of freshly ground black pepper.
- Increase the heat and bring the soup to a boil. Reduce the heat to a gentle simmer and partially cover the pot. Cook for approximately 25 to 30 minutes, or until the lentils are tender while still holding their shape.
- Carefully remove about 2 cups of soup and blend until smooth. Return the blended mixture to the pot and stir well. Alternatively, use an immersion blender directly in the pot and briefly blend only part of the soup.
- Stir in the chopped kale or collard greens. Simmer for another 5 minutes, or until the greens are tender.
- Remove the soup from the heat and stir in 1 tablespoon of lemon juice. Taste and add additional lemon juice, salt, black pepper, or red pepper flakes as desired.
- Serve the lentil soup hot, with an optional drizzle of olive oil or an extra squeeze of lemon.

Variations
For a spicier lentil soup, increase the red pepper flakes or add a small amount of cayenne pepper.
For extra vegetables, add chopped celery, zucchini, sweet potato, or bell pepper. Firmer vegetables should be added early enough to become tender while the lentils cook.
Spinach can replace the kale or collard greens. Since spinach cooks quickly, stir it into the soup during the final few minutes.
For a thicker soup, blend a larger portion of the cooked lentils and vegetables. For a brothier consistency, skip the blending step or add a little extra vegetable broth.
If you prefer a brighter flavor, add extra lemon juice immediately before serving. Fresh parsley or cilantro can also provide a fresh herbal finish.
For a richer tomato flavor, stir a tablespoon or two of tomato paste into the vegetables before adding the diced tomatoes.
French green lentils can also be used, although they generally require a longer simmer than standard brown or green lentils. Continue cooking until they reach your preferred tenderness.
Storage/Reheating
Allow leftover lentil soup to cool before transferring it to an airtight container. Store it in the refrigerator for up to 4 days.
For longer storage, place cooled soup in freezer-safe containers, leaving a little room for expansion. Freeze for up to 3 months for the best quality. Thaw frozen soup overnight in the refrigerator before reheating whenever possible.
To reheat on the stovetop, transfer the soup to a saucepan and warm it over medium-low heat, stirring occasionally, until steaming hot. The lentils may absorb additional liquid during storage, so add a splash of vegetable broth or water if the soup becomes too thick.
Individual portions can also be reheated in the microwave. Heat in short intervals, stirring between each interval, until evenly heated.
For the freshest flavor, add another small squeeze of lemon juice after reheating.
FAQs
What type of lentils are best for lentil soup?
Brown or standard green lentils are excellent choices because they become tender while retaining enough structure to give the soup a hearty texture.
Do I need to soak lentils before making this soup?
No. Brown and green lentils can be rinsed and added directly to the soup without soaking. Always check the lentils for small stones or debris before cooking.
Can I use red lentils instead?
You can, but the finished soup will have a different texture. Red lentils break down much more readily during cooking, producing a softer, thicker, and creamier soup.
Can I make lentil soup without blending it?
Yes. Blending part of the soup simply creates a thicker, creamier consistency. You can skip this step for a more rustic soup with a lighter broth.
Can I substitute spinach for kale?
Yes. Fresh spinach works very well. Because it wilts much faster than kale, add it near the end of cooking and simmer only until tender.
Why should I add lemon juice to lentil soup?
Lemon juice adds acidity and freshness, which balances the earthy lentils, tomatoes, vegetables, and warm spices. Add it at the end so its bright flavor remains noticeable.
How do I make lentil soup thicker?
Blend more of the cooked soup and return it to the pot. You can also simmer the soup uncovered for several additional minutes to allow some of the liquid to evaporate.
Can I freeze lentil soup?
Yes. Lentil soup freezes very well. Cool it completely, divide it into freezer-safe containers, and freeze it for up to 3 months for the best texture and flavor.
Can I double this lentil soup recipe?
Yes. Double the ingredients and use a sufficiently large pot to prevent overflowing. Cooking time should remain fairly similar, although a larger quantity of liquid may take longer to reach a boil.
What can I serve with lentil soup?
Lentil soup pairs well with crusty bread, toasted sourdough, pita bread, a simple green salad, roasted vegetables, or a grain-based side dish. It is also hearty enough to serve as a complete meal on its own.
