Instant Pot Lentil Soup is humble, unconditional love in a bowl. Whatever life is throwing at you this week, this quiet, soul-soothing soup is here to nourish.

Feeling on top of the world? You’ll be even more dynamo after your first bite. Can’t remember the last time your socks matched? This Instant Pot lentil soup doesn’t care. It will cozy on up with you anyway.

The beauty of lentil soup is its understatement. While it isn’t fancy, I’d feed it to my dearest company (and I have many times!). Its satisfying, hearty texture and familiar, yet vibrant flavor will wrap you up with every bite. 

This soup also earns bonus points for affordability. An entire pot of lentil soup costs about $10 to make, but it tastes like a million bucks. Plus, it’s freezer-friendly, making it ideal for meal prep. 

Lentil soup will never sing its own praises, and it doesn’t need to. You’ll be singing them on its behalf!

Why I Love This Easy Lentil Soup

A lover of sun and warm weather, I struggle during this stretch of the year, when the sparkle of the holidays is behind but summer still feels forever away. However, one of the things that brings me cheer all winter long is making recipes that shine their brightest when the cold is at its worst.

While I’d happily eat Instant Pot lentil soup any night of the week and in any temperature, it tastes especially satisfying when the wind is blowing and the frost is creeping into the corners of our windows. Each bite instantly transports me to a place of warmth, comfort, and deliciousness. 

Just like this Lentil Soup, it’s healthy, super filling, warming, and the best kind of recipe to have in your refrigerator. It reheats like a dream and tastes better and better as the week goes along.

How to Cook Lentil Soup in the Instant Pot

This easy lentil soup does require a little chopping on the front end, but once you have the ingredients prepped, it is completely hands off, especially if you make it in an Instant Pot. (If that sounds appealing, be sure to check out this roundup of my favorite hands-off dishes: 15 Healthy Instant Pot Recipes!)

I first discovered the beauty of Instant Pot lentils back when I made this Instant Pot Lentil Curry.

Although the total amount of time to cook lentils in an Instant Pot is pretty comparable to the time you’d need on the stove, I find that the texture of the Instant Pot lentils is superior.

I love that I never need to check or stir the lentils the entire time the soup cooks. (For another maintenance lentil recipe or if you don’t have an Instant Pot, try this Crockpot Lentil Soup.) 

The Ingredients

  • Lentils. I made this pressure cooker lentil soup with French green lentils (also called “Puy lentils”) because I love their lightly peppery flavor, and they hold their shape and texture nicely too. In addition to being yummy, lentils are a great addition to soup because they are ultra nutritious. Lentil soup is healthy and packed with protein, B vitamins, potassium, magnesium, and iron. You do not need to soak the lentils before adding them to lentil soup.
  • Vegetables. Adding classic soup veggies like onions, carrots, celery, and garlic makes this soup extra hearty, healthy, and flavorful.
  • Herbs & Spices. I used a combination of fresh thyme, smoked paprika, and black pepper. The thyme gives the lentil soup an earthy Italian vibe; the smoked paprika makes it very subtly smoky and adds another dimension of flavor.
  • Tomatoes. Pantry staples to the rescue! Crushed tomatoes form part of the soup liquid, and the fire-roasted tomatoes add a richer flavor.
  • Vegetable Broth. To keep this as a vegetarian or vegan lentil soup, use vegetable broth. You can certainly make it with chicken broth if that’s not a concern for you.
  • Toppings. I highly recommend both a sprinkle of fresh parsley and Parmesan cheese. Crusty baguette dunking comes highly recommended too!

  3. Stir the soup, and remove the thyme stems. Adjust taste and texture as desired. Serve hot with desired toppings, and ENJOY!

Recipe Notes and Variations

  • To Make VeganAs written, this is a vegan lentil soup, but if you don’t need the recipe to be dairy free, I highly recommend grating Parmesan cheese right over the top.
  • To Add Meat. To make Instant Pot lentil soup with sausage, brown the sausage with the onion first, and then once it’s fully cooked, add the remaining ingredients in the order listed.
  • French Lentil Soup with Bacon. Classic! Cut the bacon into pieces, and start the recipe by browning the bacon in the Instant Pot first using the sauté setting until crispy. Remove to a plate lined with paper towels, and then make the soup as directed. Stir in the bacon at the end.
  • Instant Pot Lentil Soup with Ham. You can stir in diced, cooked ham after the soup has finished cooking.
  • Lentil VariationsIf you prefer to make Instant Pot red lentil soup or even brown lentil soup instead of French lentil soup, those swaps will certainly work too. For red lentil soup, I’d suggest cutting the pressure cooking time by a few minutes, as red lentils are more fragile and won’t hold their shape as well during pressure cooking.
  • No Instant Pot? You can also make this soup on the stovetop. See recipe notes for more details. Or give this stovetop Curry Lentil Soup a try.

How to Store and Reheat Instant Pot Lentil Soup

  • To Store. Place leftover soup in an airtight storage container in the refrigerator for up to 5 days.
  • To Reheat. Gently rewarm this soup in a Dutch oven on the stove over medium-low heat until hot. You can also reheat this soup in the microwave.
  • To Freeze. Store soup in an airtight, freezer-safe storage container in the freezer for up to 3 months. Let thaw overnight in the refrigerator before reheating.

Tools Used to Make Instant Pot Lentil Soup

  • 6-Quart Instant Pot. Larger sizes work too. If making in a 3-quart Instant Pot, I suggest halving the recipe (no need to change the Instant Pot pressure cook time, no matter the size).
  • Cheese Grater. The easiest way to grate cheese right on into your soup…and into anything else.
  • Green Lentils. <—These are the ones I used.

Instant Pot Lentil Soup

4.90 from 212 votes
Instant Pot Lentil Soup – an easy, healthy recipe for French lentil soup made in the electric pressure cooker. So simple, hearty, and delicious! Gluten free, vegan, and freezer friendly. Recipe works with any color of lentils (red, green, or brown).
This recipe as written yields a very thick soup, so feel free to thin it with additional broth if you prefer a thinner consistency.

Prep: 5 minutes
Cook: 45 minutes
Total: 50 minutes

Servings: 8 cups (6 servings)

Ingredients
  

  • 2 tablespoons extra-virgin olive oil
  • 1 medium yellow onion small diced
  • 4 medium carrots
  • 3 stalks celery
  • 4 springs fresh thyme
  • 1 teaspoon kosher salt
  • 3/4 teaspoon smoked paprika
  • 1/2 teaspoon black pepper
  • 1 1/2 cups French green lentils
  • 4 cloves garlic minced (about 4 teaspoons)
  • 1 can fire-roasted diced tomatoes (15 ounces)
  • 1 can crushed tomatoes (15 ounces)
  • 4 cups low-sodium vegetable broth
  • Chopped fresh parsley for serving
  • Freshly grated Parmesan cheese optional for serving
  • Crusty bread optional for serving

Instructions
 

  • Drizzle the oil into the Instant Pot. Set to SAUTE. Once the oil is hot, add the onion and stir. Continue to cook the onion, stirring often, until the onions are very soft and beginning to nicely brown and break down, about 8 minutes.
  • While the onion cooks, peel the carrots and cut into small dice. Small dice the celery as well. Add the carrots, celery, thyme springs (you can tie them together if you like to make them easier to fish out later), salt, smoked paprika, and pepper. Sauté until the carrots and celery are barely soft, about 2 minutes.
  • Add the lentils and garlic to the pot and stir to coat them in the spices. Let cook 30 seconds, until the garlic is fragrant. Add the diced tomatoes, crushed tomatoes, and vegetable broth.
  • Cover and seal the Instant Pot, and then set to cook on HIGH pressure for 15 minutes. After 15 minutes of high pressure, allow the cooker to release pressure naturally. This will take about 10 to 15 additional minutes.
  • Open the lid and stir the soup. Remove the thyme stems, leaving the leaves in the soup. If the soup is too thick for your liking, thin with a bit of water or additional stock until you reach your desired consistency. (We tend to like our soups pretty thick and hearty around here.) Taste and adjust the seasonings as desired. Serve hot with a sprinkle of parsley, Parmesan (if using), and bread for dipping.

    1. I’m sorry to hear the recipe wasn’t to your taste, Susan. I know it’s disappointing to try a new recipe and not enjoy it. I (and many other readers) have enjoyed it, so I really wish they would’ve been a hit for you too!

    1. Hi! This is Instant Pot Lentil Soup, I’ve linked to two different curry recipes in the post, one of them being my instant pot lentil curry. Here is the link to that one: https://www.wellplated.com/instant-pot-lentil-curry/ Enjoy!

    2. This my go-to IP lentil soup. I prefer to make it with chicken broth unless my guests are vegetarian. A must-add is the SMOKED paprika. Regular paprika will not do for this soup – will never have the same impact. I wonder if some people who feel the soup is bland have used regular paprika. Add seasoning to take when done, and Parmesan only makes everything better. . It’s a great, easy soup.

  1. Delicious! My hubby looked at it and rolled his eyes and then he tasted it and really enjoyed it!! I will say he can be pretty picky, as I have to purée the canned tomatoes so there aren’t any chunks lol. I did not have any fresh herbs, so I used dried and after it was all cooked I through in a chunk of the rind of Parmesan in. Garnished with grated parm and the French bread went very well with it! Looking forward to having it for lunch tomorrow! Thanks for the great recipe!5 stars

    Hi. I made the recipe but cut it in half for the 3 quart instant pot. It came out OK but I would say that it definitely taste sour and is not spicy enough. Do you have any recommendations for getting it right?

    Thanks!
    Bill

    1. Hi Bill! Sorry to hear that, I’ve not heard of this happening before. Doing some research online this seems to be an indication that the lentils are bad. I would try a different brand and check the expiration date before making it again. Hope this helps!

  3. I’ve made this a couple of times and have loved it! But I wanted to know if I could use dried Thyme? Our store hadn’t had fresh Thyme when I need it. If yes, how much? Thank you in advance!5 stars

    1. Sure you can! “a good rule of thumb is to substitute 1/2 teaspoon of dried thyme for 1 teaspoon of fresh thyme leaves”. Hope this helps!

  4. so tasty!! plenty of flavor and i love how it’s packed with veggies and fiber. i had firm tofu that needed to be used up so i chopped that up really small cubes, air fried and then threw it in after the stew was finished. i also like it more thick soupy so i added cornstarch after. delicious and perfect for fall!5 stars

  5. This soup was delicious! This was my first time making lentil soup. I didn’t have the fire roasted tomatoes but substituted regular diced. I think the fresh thyme is what made the soup so flavorful. I made a sourdough bread and it was amazing. Thank you for sharing the soup recipe!5 stars

  6. Amazing lentil soup! It was so easy to make. I did not have thyme so subbed sage and rosemary. I used 6 cups of water/broth instead of 4 and was satisfied with the consistency. (Not too thick or too thin.) I will be putting this on the regular list or dinners.5 stars

  7. This is a perfect recipe. It is so incredibly tasty. I just have one suggestion. Don’t dump the salt in all at once. Instead, salt as you go, using a salt shaker.5 stars

  8. This was so delicious. I used a can of Rotel for the fire-roasted tomatoes, did not have celery on hand, and used dried thyme. I served it with roasted broccoli and even my meat and potatoes husband loved it. We are trying to eat mostly vegan meals, and this is a super easy and tasty recipe.5 stars
