The Best Lentil Soup with Lemon and Turmeric

What You’ll Need To Make My Favorite Lentil Soup

The first time I had lentil soup I wasn’t really expecting to like it. I thought it was going to be bland and boring, but thanks to a combination of spices and fresh lemon, it tasted amazing (almost addictive) and so comforting. I make this soup during every season, it’s that good!

The ingredients needed to make lentil soup are simple and most are probably sitting in your kitchen already. Here’s what you’ll need:

  • Lentils — I use brown, red, or French lentils to make the soup and add them uncooked. The lentils cook up to be soft, plus I love the nutritional benefits of lentils. They are high in fiber, B vitamins, iron, protein, and are low in fat.
  • Garlic, onion and carrots add nutrients, texture, and color to the soup.
  • Ground cumin, ground coriander, and ground turmeric add spice and color.
  • Broth — For a vegetarian/vegan lentil soup, use veggie broth (here’s our recipe) or use chicken broth (here’s how we make it).
  • Kale or spinach add even more nutrition to the soup.
  • Fresh lemon is a must for this soup. It makes all the flavors really pop. I even add slices of lemon to the bowls when serving.
  • Fresh herbs are optional, but when I have it on hand I love adding a handful of fresh dill or parsley.

The Steps for Making The Best Lentil Soup

Like quite a few of the soup recipes on Inspired Taste, this lentil soup is very simple to make. Let’s quickly walk through the steps:

Step 1: Cook onions and carrots in a large pot (I use my Dutch oven) until they begin to soften and are starting to smell sweet. If you have them in the fridge, celery or fennel would be lovely added to the pot, too.

Step 2: Stir in garlic, cumin, coriander, and turmeric. I only cook the aromatics for 30 seconds or so. This short time allows the garlic and spices to warm up, which I think helps them release even more flavor to the soup.

Step 3: Rinse and pick through the lentils. I add the lentils dry (uncooked) to the pot, but before doing that, I make sure to rinse them under running water. I also quickly look through them to make sure anything that isn’t a lentil is removed (sometimes other beans or grains sneak in, especially when you get them from the bulk aisle).

Step 4: Add the lentils and broth. With almost all the soup ingredients in the pot, I bring the soup to a simmer and cook, partially covered, until the lentils are soft. This takes 30 to 40 minutes.

Step 5: Taste and season the soup then stir in greens. Whether you use kale or spinach in the soup, you only need to cook them for a few minutes before serving.

Step 6: Add fresh lemon juice and fresh herbs. Just before serving, I squeeze lots of fresh lemon juice into the soup. This brightens all the flavors and really makes the soup taste fresh and fantastic. Fresh herbs like dill or parsley are also a nice touch.

As you can see from our photos, I add slices of lemon to the soup, too. This is completely optional, but it does add even more lemony flavor and cues whoever you are serving the soup to that we’ve added lemon.

Should I Blend Lentil Soup?

Whether you blend the soup is entirely up to you. Lots of recipes for lentil soup call for blending all or part of the soup the thicken it. I don’t usually do this since I think the soup is thick enough and I enjoy the combination of broth and the texture of whole cooked lentils.

If you do want to blend the soup, use an immersion blender or a stand blender with the stopper removed and a paper towel placed over the hole. This way, as you blend the hot liquid, steam can be released (not doing this can cause quite a mess).

Make Ahead and Storing

Lentil soup will keep well for up to four days in the fridge and in my opinion, gets better over time. You might find that the lentils absorb some of the extra liquid in the soup as it sits in the fridge. To bring it back to more of a soup-like consistency, simply add a splash of water or broth before reheating.

You can also freeze the soup. It should keep for several months. Simply defrost and reheat before serving.

This is our favorite lentil soup recipe. I make this soup with lentils, carrots, turmeric, and fresh lemon whenever we are in need of some healthy comfort food. It’s savory, satisfying, and utterly delicious. I like quite a bit of fresh lemon in this soup and actually serve the soup with slices of lemon. This adds even more lemony flavor and shows that lemon was added to the soup.

Makes 6 to 8 servings

You Will Need

2 tablespoons olive oil

2 cups finely chopped onion (1 medium onion)

1 1/2 cups chopped carrot (2 large carrots)

2 teaspoons minced garlic (3 cloves)

1 teaspoon ground cumin

1/2 teaspoon ground coriander

1/2 teaspoon fresh ground black pepper

1/2 teaspoon ground turmeric

2 cups (12 ounces) lentils, picked and rinsed

8 cups chicken or vegetable broth

2 heaping cups shredded kale or spinach

1 to 2 lemons

1/4 cup chopped fresh herbs like parsley or dill, optional

Fine sea salt, to taste

Directions

    Heat the oil in a large pot (like a Dutch oven) over medium heat. Add the onions, carrot, and 1/4 teaspoon of salt and cook, stirring occasionally until they are softened and starting to smell sweet, about 5 to 7 minutes. Stir in the garlic, cumin, coriander, black pepper, and turmeric and cook for 30 seconds.

    Stir in the lentils and broth. Increase the heat to high and bring just to a boil. Taste then adjust with salt (we add between 1/2 and 1 teaspoon depending on how well seasoned the broth is). Reduce the heat to a simmer and cook, partially covered, until the lentils are tender, 35 to 40 minutes.

    Uncover the pot and stir in the kale (or spinach) and cook, uncovered, another 5 minutes. Take the soup off of the heat, and then stir in the juice of half a lemon and the fresh herbs. Taste the soup, and then season with additional salt and/or lemon juice. (I like quite a bit of lemon.)

    Serve or if you prefer the soup to be blended, use an immersion blender to blend until your desired consistency. Alternatively, you can use a stand blender to blend all or part of the soup. For even more lemon flavor, serve with a few lemon slices.

Adam and Joanne's Tips

  • The soup will keep stored in the refrigerator up to four days and in the freezer for several months. If when reheating the soup, it seems too thick or dry, add a splash of extra broth or water.
  • For some extra flavor, cook bulk sausage or ham with the onions and carrots.
  • Nutrition facts: The nutrition facts provided below are estimates. We have used the USDA database to calculate approximate values. Sodium will vary depending on the broth used.

      You are absolutely right. We addressed this in the article but we did not explain the lemon slices in the recipe. We have added a note to the recipe to make it more clear.

    This soup is off the charts delicious! The blending flavors of tumeric and lemon go well with the spinach and lentils! We used multicolored lentil mix, fresh parsley and spinach from the farmers market. This soup freezes wel for healthy lunches! Thanks for sharing Joanne and Adam, making another batch today!

    I made this for lunch on a grey, rainy day and GAWSH it was good. I used vegetable stock instead of olive oil to sauté the vegetables and I used red lentils which hardly take any time to cook. I’ve been posting it all over my social media with links to this recipe. It’s so delicious.

    I couldn’t care less for lentils but this is the second time I’ve made this soup since the recipe was posted a week ago. So I guess I care about lentils now? It’s so easy and tasty. I’m with Adam and Joanne: lemon, baby!! This second time around I added Bok Choy and portobello mushroom bc i had it available but the original recipe is perfect the way it is.
