Very Best Lentil Soup

Lentil soup is a classic vegetarian soup recipe. It’s hearty, healthy, delightfully filling (with plant-based protein), and warming on those cold, wintery days. While there are many variations of lentil soup, you can’t go wrong with a simple, delicious Mediterranean version.

When it comes to lentil soup recipe, let’s remember that simple does not equal boring. Oh no, this recipe is anything but that!

It’s packed with rich flavor, it’s hearty enough to be eaten as dinner, and it’s easy enough to whip up with a few pantry staples and fresh vegetables. That’s why it’s the very best.

When I previously showed you how to cook lentils (so they’re not mushy), I also highlighted why lentils are a powerhouse ingredient in vegan and vegetarian meals. They’re high in fiber, carbohydrates, and most importantly, protein. That means this lentil soup is not just an appetizer soup, but it’s a satiating full meal. And an economical one to boot.

Lentil soup is hearty (yet light), comforting, satisfying and should definitely be in your regular dinner rotation. Bonus, you can meal prep and freeze it as well!

What’s In This Vegan Lentil Soup

A cup of green lentils goes a long way in this cozy, chunky soup. But it’s really the rest of the ingredients that makes your taste buds dance.

  • Mirepoix Vegetables: Chopped celery, carrots, onions and garlic are the classics that make us feel closest to home.
  • Roasted Tomatoes: A can of fire roasted tomatoes adds a hint of smokiness and lends to this soup’s gorgeous red tone.
  • Tomato Paste: All you need are two tablespoons to intensify the body of the soup.
  • Kale: An easy way to amp up the antioxidants, vitamins, nutrients, and colors in this soup.
  • Earthy Herbs: A blend of cumin, oregano, basil, and thyme embodies that Mediterranean flavor.
  • Liquids: You can use water or broth or a mix of both, which is what I usually do.
  • Lemon: Helps to brighten and balance out the deep flavors.

Which Lentils to Use

Green or brown lentils are the best choice for this soup. They have a mild, earthy flavor that slightly breaks apart when cooked, but still maintain their shape. Red lentils break down the fastest and become mushy. And French lentils (also called Lentils de Puy) are great for being tossed in a side dish or lentil salad as they have the firmest texture, but they require more time to cook in a soup.

How To Make The Best Lentil Soup Recipe

  • Sauté the vegetables. In a large soup pot, heat the oil and sauté the onion, celery, and carrots for about 5 minutes.
  • Add the spices. Stir in the tomato paste, garlic, dried spices, salt and pepper. Cook for 2 minutes until fragrant.
  • Add the lentils, diced tomatoes, and broth. Bring it all to a boil, reduce the heat to low, and let the soup simmer for 25 minutes. Keep the pot partially covered with the lid.
  • Blend it. For a more creamier texture, use a Vitamix immersion blender (it’s so powerful!) to spot blend for a few seconds.
  • Add the rest. Stir in the kale, lemon juice, and let it all simmer for 1-2 more minutes. Then taste test to see if you need to add anything else.

Garnishing Options

Whether you’re serving this soup to guests or enjoying as a meal for two, it’s always fun to perk it up a bit.

  • Fresh Herbs: Sprinkle on freshly chopped parsley or cilantro.
  • Crispy Bits: Quickly whip up crispy shallots for added crunch or crumbled bacon bits if you’re not vegan.
  • A Touch Of Creaminess: Drizzle a little coconut cream or sprinkle freshly grated parmesan on top.

Storing And Reheating Leftovers

  • To Store: This will keep in the fridge for up to 5 days in a sealed storage container.
  • To Freeze: Keep this in a freezer safe container or pour into a silicone freezing tray for pre-made servings. It will last for several months in the freezer.
  • For Reheating: If you’re reheating a single serving, just add it to a bowl and pop it in the microwave for a few minutes until warmed through. But if you’re heating up an entire batch, add it back into a pot and warm it up on the stovetop.

More Cozy Fall Soups & Stews

It goes without saying that a solid list of soups is a winter essential. And if you’re vegetarian, a few of these recipes can be modified to your liking.

Ingredients

  • 1/4 cup olive oil
  • 1 onion, small diced

  • 2 celery stalks, small diced
  • 2 tablespoons tomato paste

  • 2 teaspoon cumin
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1 teaspoon dried thyme
  • salt and pepper, to taste

  • 6 cup vegetable broth or water
  • 1 cup green or brown lentils

  • You can keep the soup chunky, or use an immersion blender to create a more creamy texture, by spot blending for just a few seconds.
  • Stir in the kale and lemon juice, and simmer for an additional minute or two to soften the kale. Taste the soup, and add any additional lemon juice, salt, or pepper before serving.

Lisa's Tips

  • Because vegetable broth usually comes in 32 ounce containers (4 cups), I add 4 cups of broth and 2 cups of water to this recipe. Just so I don't have a half used container of broth.
  • You can substitute 3 teaspoons of Italian seasoning for the oregano, basil, and thyme.
  • As the soup sits, the lentils may soak up some of the liquid, thickening up the soup. You can always add more broth or water to thin it out. Or blend it creamier with my favorite Vitamix immersion blender.

  1. Another absolutely delicious recipe! Thank You!!

  2. I made this soup tonight and it hit the spot and was so flavorful! I love the combination of spices and fire roasted tomatoes are my new favorite ingredient! The only thing I will do differently next time is use a smaller lemon or use just half of a large lemon. It was slightly over powering. I decided not to use the immersion blender because I like my soups a little chunky and it turned out to be the perfect consistency for me. Thanks for another wonderful recipe Lisa!

  3. Hello, I’m just  wondering why the calories are so high for such a healthy recipe, I calculated the WW points and it comes to 13:(
    I guess I can cut down on the olive oil or even just try using an olive oil spray instead. Thank you for this recipe!
    Anna

    • Hi Anna – most of the calories in this recipe are coming from the lentils, canned tomatoes, and olive oil. You can reduce the olive oil a little bit if you’d like. Enjoy!

  4. Yes, I have to agree, this is the very best lentil soup. It gets even better after sitting a day or two. Also, I added some sliced chicken and mushroom sausage when I served this as leftovers. Delish! 
    As always, thank you, Lisa for your great recipes. 

  5. Great soup recipe, all the family loved it . 

  6. You don’t lie do you!?
    This is indeed the very best lentil soup. DEEEELISCH! Just made a batch and it is a warm bowl of goodness.
    I put half of the soup into my Vitamix blender, pureed it smooth and added it back in to the pot. After adding the kale, I added more water as the consistency was thick.
    The taste is … wow. THANK YOU for another winner.

  7. Thanks Lisa! This worked out great. I used 1 tsp oil to lower the fat and added a 1/8 tsp of turmeric.

  8. If I don’t have the vitamix immersion blender, any other options?

  9. Would canned tomatoes work. Don’t have fire roasted tomatoes; trying to use what I have on hand. Thanks.

  10. I loved this soup. All basics in the pantry and fridge. i put less liquid in for the right consistency. A great winter staple. Quick to make for dinner. leftovers are even better.

  11. Make it for lunch!. Just amazing. Thank you so much.

  12. The soup turned out wonderful!! Very tasty and full of flavor. I agree with one of the earlier posts to not add a whole lemon but wrote how many tablespoons – was very lemony, but still still delicious! 

  13. Such an easy, lovely and healthy soup. It was so delicious! Luckily I have some leftovers for lunch ;-)

  14. So tasty!! And easy!! I even got to the very end and forgot the lemon juice and kale, and it was still delicious! 

  15. I made this for dinner tonight and it really hit the spot! It was delicious. Thanks for another great recipe. I may add some sausage next time.

  16. This recipe is so easy and the flavors so good! I love a simple soup recipe at this time of year.

  17. This was really yummy. I added half a chopped chilli pepper for some spice.

  18. My Wife made this evening and it turned out awesome! Our weather is cold and this hit the spot this evening. Great recipe, thank you for sharing.

  19. Very good but you might consider changing the “juice of 1 lemon” to “lemon juice to taste”.  I love lemon but it was overpowering.

  20. What a delicious soup recipe! I’ve tended to make lentil soup with more of an Asian flavor, I look forward to trying your version!

  21. Yum! This lentil soup is so flavorful and filling. I love all the vegetables and plant protein. It’s a perfect weeknight soup especially since it’s getting cooler! My family loved it so I will definitely be making it again this week! 

  22. I love a good soup at this time of year and this definitely sounds like one to try! So hearty and healthy too!

  23. What a warm, comforting and delicious soup! Can’t wait to try it.

  24. Lisa, Do you use dry or canned lentils for this recipe?

  25. This looks so good. Do you think spinach would work fine vs. kale?
