Lemony Lentil Soup Recipe

Who’s ready for a light and refreshing bowl of lemony lentil soup? ♡

A record number of you all have been making (and loving!) this lentil soup recipe while we have all been staying at home these past few months.  So for any of you who have yet to give it a try — or any of you who may be searching for ways to use up all of those lentils stockpiled in your pantry — I thought I would bump this recipe back to the top of the blog for everyone to enjoy!

Quite simply, this is my all-time favorite lentil soup recipe.  It was inspired by our favorite Middle Eastern café back in our old neighborhood in Kansas City, whose famous lentil soup I ordered approximately one million times over the years and missed like crazy once we moved away from the city.  So I set to work a few years ago trying to recreate it, and I think that I came really close here!

The recipe itself is actually quite simple.  Red lentils are simmered until softened and combined with a simple mix of veggies, spices and lots of lemon juice to brighten things up.  But the restaurant version of the soup also featured two signature ingredients — corn and a pinch of saffron — which add the perfect hint of sweetness that make this soup perfectly-balanced and just lovely. ♡  Barclay and I turn to this soup often because it’s easy to make and full of feel-good ingredients.  But most of all, we just love it because it’s crazy-good and will forever remind us of home.

If you haven’t tried it yet, I can’t recommend this one enough!

Lemony Lentil Soup Ingredients:

To make this lemony lentil soup recipe, you will need the following ingredients:

  • Veggies: A simple mix of white onion, carrots and garlic.
  • Veggie stock: Or you could also use chicken stock, if that’s what you have on hand.
  • Red lentils: Which I love for this soup because they break down and purée easily.
  • Corn: Just your basic frozen or canned whole-kernel corn.
  • Spices: A cozy mix of ground cumin, curry powder, cayenne and saffron (optional, but really delicious if you happen to have some on hand).
  • Fresh lemon: Whose zest and juice we will add to the soup.  I also recommend serving the soup with extra lemon wedges, if people would like to make their bowls even more lemony.
  • Salt and black pepper: For seasoning, as always.

How To Make Lentil Soup:

I have included detailed instructions below for how to make this lentil soup in either an Instant Pot, Crock-Pot or on the stovetop.  But here is a quick overview!

  1. Sauté the veggies. I really recommend taking an extra few minutes to sauté the onion, carrots and garlic before adding them to the rest of the soup, to bring out the best of their flavors.  (This may require an extra sauté pan, if using a Crock-Pot.)  But if you are in a hurry, you can just add these ingredients in with Step 2 below.
  2. Simmer. Stir in the vegetable stock, lentils, corn, cumin, curry powder, cayenne and saffron (if using) until combined.  Cover and cook on the stovetop (or pressure cook or slow cook) until the lentils are tender.
  3. Blend (optional). Using either a hand blender or traditional blender, puree the soup until it reaches your desired consistency.  (If using a traditional blender, please see safety notes below.)
  4. Season. Stir in the lemon zest and juice, then season the soup with a few generous pinches of salt and pepper, as needed.
  5. Serve. Serve warm, garnished with an extra fresh lemon slice if desired.

Possible Variations:

Feel free to experiment and customize this soup however you might like!  For example, you could…

  • Serve the soup chunky. Just skip the puréeing step and enjoy the soup as-is!
  • Make it spicier. Add extra cayenne if you would like to give the soup a bit more heat.
  • Add fresh herbs. Fresh mint and/or cilantro would also be delicious served with this soup.
  • Add yogurt. Feel free to also serve the soup garnished with plain yogurt, if you would like to make it creamier.
  • Add greens. You could also stir some fresh baby spinach or chopped kale into the soup just before serving, to add some greens.

Ingredients


Instructions

Stovetop Instructions:

  1. Sauté the veggies. Heat oil in a large stockpot over medium-high heat.  Add onion and carrots and sauté for 5 minutes, stirring occasionally, until the onions are soft and translucent.  Add garlic and sauté for 1 more minute, stirring occasionally, until fragrant.
  2. Simmer. Stir in the vegetable stock, lentils, corn, cumin, curry powder (plus saffron and cayenne, if using) until combined.  Continue cooking until the soup reaches a simmer.  Then cover and cook for 15 minutes, stirring occasionally, until the lentils are completely tender.
  3. Blend (optional). Using either a hand blender or traditional blender, puree the soup until it reaches your desired consistency.  (If using a traditional blender, please see notes below.)
  4. Season. Stir in the lemon zest and juice until combined.  Taste and season the soup with a generous pinch or two of fine sea salt and black pepper, as needed.
  5. Serve. Serve warm, garnished with an extra fresh lemon slice if desired.

Instant Pot (Pressure Cooker) Instructions:

  1. Sauté the veggies (optional). Press the “Sauté” button on your Instant Pot.  Add oil and let it heat until shimmering. Add onion and carrots and sauté for 5 minutes, stirring occasionally, until the onions are soft and translucent.  Add garlic and sauté for 1 more minute, stirring occasionally, until fragrant.  Press “Cancel”.
  2. Cook. Stir in the vegetable stock, lentils, corn, cumin, curry powder (plus saffron and cayenne, if using) until combined. Cover the pot and set vent to “Sealing”. Cook on high pressure for 8 minutes, followed by a quick release.
  3. Blend. Using either a hand blender or traditional blender, puree the soup until it reaches your desired consistency.  (If using a traditional blender, please see notes below.)
  4. Season. Stir in the lemon zest and juice until combined.  Taste and season the soup with a generous pinch or two of fine sea salt and black pepper, as needed.
  5. Serve. Serve warm, garnished with an extra fresh lemon slice if desired.

Crock-Pot (Slow Cooker) Instructions:

  1. Slow cook. Add onion, carrots, garlic, vegetable stock, lentils, corn, cumin, curry powder (plus saffron and cayenne, if using) to the bowl of a large slow cooker, and stir to combine.  (No olive oil needed.)  Cover and cook on high for 2-3 hours, or on low for 5-6 hours, until the lentils are completely tender.
  2. Blend. Using either a hand blender or traditional blender, puree the soup until it reaches your desired consistency.  (If using a traditional blender, please see notes below.)
  3. Season. Stir in the lemon zest and juice until combined.  Taste and season the soup with a generous pinch or two of fine sea salt and black pepper, as needed.
  4. Serve. Serve warm, garnished with an extra fresh lemon slice if desired.


Notes

Traditional blender instructions: If using a traditional blender to purée the soup, please exercise caution (as always) as hot liquids expand when blended.  I would recommend blending the soup in two batches, so as not to overflow your blender.  I always slightly tent open the cap on the blender lid (or gently place a kitchen towel over the cap opening) so that excess hot air can escape while the hot soup is being blended.  Once the soup is ready to go, return it to the stockpot and continue on with the recipe.

Sautéing the veggies: *I really recommend sautéing your onions, carrots, garlic if you can before cooking them in the Instant Pot or slow cooker.  (I always think the flavor is so much better.)  But that said, if you’re in a rush, you can just toss them in at the same time as your other ingredients. :)

Storage instructions: Any leftovers can be refridgerated in a food storage container for up to 3 days or frozen for up to 3 months.

  1. Very very good! The corn is great contrast to spices!! Definitely our new favorite lentil soup.

  2. Amazing soup ! Quick to make & tasty.

  3. This soup was heaven! 😋 Our family loves lentil soups in all forms, but this is, by far, the new favorite! Thank you so much for this simple, beautiful, delicious recipe!!! 💜

  4. Have you made this before with green or
    Brown lentils?

  5. Can I use regular lentils with this recipe instead of the red lentils?

    thank you.

  6. Absolutely delicious soup! Followed the recipe exactly – something I hardly ever do – and it turned out amazingly well. Can’t wait to make it again!

  7. Simply Delicious …and Healthy!

  8. This lentil soup was a big hit. Loved the lemony flavour and being able to use up red lentils. The immersion blender allowed me to maintain a nice texture. I think my heavy duty blender would have puréed too much and the texture would have been lost. Thanks for a new addition to the rotation.

  9. An absolute fave! I’ve made it many times – so delish!

  10. I made this in April and only had a can of creamed corn, instead of regular. I just increased the lemon slightly to compensate for the extra sweetness. It was so dang delicious! Today I’m having the rest that I froze, cant wait.

  11. Read the recipe and made it stat. So luscious and comforting!

  12. So nice to see this recipe pop up again. I have been making it for quite awhile now. Yum.

  13. Soup is my favorite lunch so I had to try this right away. It was easy and delicious. Even my husband liked it and he isn’t a lentil lover. We’ll be having it again soon!

  14. Very yummy and satisfying soup. I did not purée it as I like my soup chunky. Felt it needed extra salt and spiciness….added sriracha sauce for kick. Also added fresh dill at end, was good but coriander is probably a better choice. Made a full meal out of it by pouring it on a bowl of baby spinach and cooked rice.

  15. Used to eat this during my college years at a Persian restaurant & loved it. Made the recipe tonight & it brought back all the memories. It’s sooo good. Hit the spot!

  16. Absolutely delicious!! I always make half a recipe first in case the family doesn’t like it but I wish I had made the whole recipe for this one. I could eat the whole pot myself!

  17. absolutely delicious. definitely one to come back to. my favorite part? the simplicity of it all.

  18. OMG! This looks like a very healthy and yummy soup.
    Thanks for sharing.

  19. Absolutely delicious!!
    It is a keeper.

  20. Soooo good! I used 2 parts veggie stock & 1 part chicken stock just because and a few handfuls of roughly chopped spinach. Loved it!
