Lentil Soup

Meet the BEST lentil soup recipe! Made with dried lentils, fresh vegetables, flavorful spices, and hearty greens, it's simple, nourishing, and delicious.

Lentil soup

This lentil soup recipe might surprise you. Sure, it’s simple. But that doesn’t mean it’s bland or boring.

This lentil soup is packed with hearty greens, tender vegetables, and fiber- and protein-rich lentils. Fresh herbs and spices fill it with complex flavor, and a splash of vinegar adds a delicious tangy kick.

It’s not just my best lentil soup recipe—it’s one of my best recipes, period. It’s been a staple in my rotation for years. I love that it’s easy to make with mostly pantry ingredients and that it’s nourishing, warming, and satisfying. If you ask me, it’s the perfect healthy dinner for a winter weeknight (save any leftovers for lunch the next day!). I hope you love this classic lentil soup as much as I do.

Lentil soup recipe ingredients

Lentil Soup Ingredients

Here’s what you’ll need to make this lentil soup recipe:

  • Lentils, of course! I recommend using green or French green lentils because they hold their shape in the soup, adding satisfying texture. Brown lentils are also a fine option. Don’t use red lentils here—they’re too mushy for this recipe.
  • Extra-virgin olive oil – For richness.
  • Onion, garlic, carrot, and celery – They create the soup’s aromatic base.
  • Fresh kale – You’ll use the whole leaves, stems and all!
  • Fire-roasted diced tomatoes – I love the smoky flavor that fire-roasted tomatoes add to this soup. In a pinch, regular diced tomatoes will work here too!
  • Vegetable broth – Make homemade vegetable broth, or use store-bought.
  • Fresh thyme – For citrusy, woodsy flavor. I like to bundle whole sprigs together with kitchen twine. Then, I add the bundle to the soup like a bay leaf, removing it before serving. Bundling the sprigs like this is SO much quicker than picking and measuring the leaves.
  • Cumin – The secret ingredient! It adds savory, earthy depth of flavor.
  • White wine vinegar – It gives the soup a bright, tangy kick.
  • And salt and pepper – To make all the flavors pop!

Find the complete recipe with measurements below.

Variations

Don’t have these exact ingredients on hand? These swaps work nicely:

  • Replace the kale with another leafy green like fresh spinach or Swiss chard.
  • Use 1 teaspoon dried thyme instead of the fresh sprigs.
  • Replace the celery with 1 small fennel bulb, diced.
  • No vinegar? No problem. Finish the soup with a squeeze of fresh lemon juice!

How to Make Lentil Soup

This lentil soup recipe is easy to make! Here’s how it goes:

First, sauté the aromatics. Heat the olive oil in a large pot or Dutch oven over medium heat and add the onion, carrots, celery, kale stems, and cumin. Season with salt and several grinds of pepper and cook, stirring occasionally, until the veggies soften, about 8 minutes.

Adding diced tomatoes to pot

Next, simmer the soup. Add the garlic, tomatoes, lentils, vinegar, thyme, and broth.

Adding lentils to soup pot with vegetables

Cover the soup and cook until the lentils are tender, 25 to 30 minutes or so. Adjust the heat as needed to maintain a gentle simmer.

Finally, add the greens. Cook until they wilt, about 5 minutes, and then season to taste.

Serve the lentil soup in bowls topped with garnishes like fresh parsley, grated Parmesan, and/or red pepper flakes. Enjoy with crusty bread!

How to Store Lentil Soup

Got leftover soup? You’re in luck! It will keep well in an airtight container in the refrigerator for up to 4 days. Simply reheat in the microwave or on the stovetop.

I actually like this soup better leftover. The flavor only improves as it sits in the fridge!

Can you freeze lentil soup?

Yes, this vegan lentil soup is freezer-friendly! Allow it to cool to room temperature, and then seal it in airtight containers or jars, leaving an inch for the soup to expand at the top. Freeze for up to 3 months.

    Easy and delicious on a cold rainy night! I used a 28 oz can of whole tomatoes because that’s what I had on hand and added red pepper flakes to the soup when I added the kale because my husband and I like spice. Garnished with parsley and Parmesan as recommended. Will definitely make again!

    Can I make this without the tomatoes? Looks delicious! Thanks.

    • Jeanine Donofrio

      Hi Emily, you could probably add more broth and maybe more vinegar or a little lemon to replace the tangy flavor that the tomatoes bring.

    Baby it’s cold outside! This soup was perfect to make for the cold we are experiencing in San Diego. It was easy to make and so delicious. The flavors were dynamic and my husband said that he didn’t think he liked Lentils and this recipe changed his mind!

    Loved the Lentil soup, filling and the flavour is great. Used red lentils as this was in my pantry and got gorgeous purple kale for it. Just started new plan for eating healthier and this was a great way to kick start it!

    Just finished making it and it’s so flavorful and warming. I can only imagine it’s even better topped with Parmesan! I plan on air frying a few pieces of sliced baguette so I can have it with some crusty bread! First time cooking with the cooking club!

    Wow! Made this soup as a part of the January cooking club. My mom and I cooked it together – though we live in different states, we love to cook together via FaceTime. I made a double batch to enjoy all week long for lunch. Delicious, cozy, and wholesome – yum!

    I make lentil soup several times over the winter months. The recipe I follow lists swiss chard as well as smoked, diced ham – it truly is more of a stew than a soup with these ingredients! Fantastic recipe!!

    Excited to try to follow through with cooking club this year! I enjoy everything about you website and it’s become a go-to spot to feed my family. Our tween daughter is exploring the world of being a vegetarian and I find your recipes so great for a whole family meatless meal or a a great base which parts of the fam can add meat to.
    Loved the lentil soup and have plenty for lunch today! Yum!

    This was so nice after days of being sick. We had some leftover veggies and a homemade parmesan broth from the week before that made this recipe a no brainer for us! I did swap fennel for celery but I’m forever a celery hater.

    Adding this one to the rotation.
