This hearty lentil soup will chase away the chill.

Whether you’re looking to eat better or chase away the cold weather doldrums, this smoky lentil soup with vegetables is just the ticket. It is best made with French green lentils, or lentilles du Puy. Prized by chefs for their earthy, peppery flavor and sturdy texture, these small lentils hold their shape when cooked, thickening the soup without turning it to mush (if you’ve ever had lentil soup so thick you could stand a spoon in it, you know what I mean). You can find French green lentils in many supermarkets—I usually get them at Whole Foods or Wegman’s—or order them online. They are worth going out of your way to find, as they work beautifully in soups and salads. If you can’t get them, it’s fine to use common green or brown lentils; just watch the cooking time as they can get mushy.

Unlike dried beans, lentils don’t require pre-soaking prior to being cooked. You simply pick over the little legumes, remove any that look broken or damaged, and cook.

What you’ll need to make Lentil soup

While I love the smoky flavor that bacon lends to this soup, if you don’t eat pork or are a vegetarian, you can omit the bacon. The soup will still be delicious but you might add a pinch of smoked paprika to mimic the flavor of the bacon.

Step-by-Step Instructions

Begin with the prep. To make the bacon easy to chop, wrap the slices you need in plastic wrap and put them in the freezer for about 15 minutes. They will be a bit stiffer when you remove them and much easier easier to cut.
Chop the bacon, onions, and celery very fine, so they aren’t too discernible in the finished soup, but keep the carrots a bit larger so they don’t disappear.

Fry the bacon in a large pot over medium heat, stirring frequently, until the fat is rendered and the bacon is crisp, 4 to 5 minutes.

Reduce the heat and simmer, partially covered, until the lentils are tender but not mushy, 45 to 50 minutes (less for common lentils).

Using an immersion blender, purée the soup a little bit at a time until the broth is slightly thickened. Go easy—if you purée the soup too much, it will get too thick and you’ll lose the integrity of the lentils. If you don’t have an immersion blender, simply transfer a few cups of the soup to a standard blender and purée, then return the blended soup to the pot.

Season to taste and adjust the consistency if necessary (the soup tends to thicken as it sits, so you may need to add some water).

This hearty lentil soup will chase away the chill.

Servings: 6
Total Time: 1 Hour

Ingredients

  • 3 slices bacon, finely chopped
  • 1 tablespoon olive oil
  • 1 large yellow onion, finely chopped
  • 1 stalk celery, finely chopped
  • 2 medium carrots, diced
  • 3 cloves garlic, chopped
  • 1 14.5-oz can diced tomatoes
  • 6 cups chicken broth, best quality such as Swanson
  • 1 cup French lentils (lentilles du Puy) or common brown or green lentils
  • ½ teaspoon dried thyme
  • 2 bay leaves
  • 1 teaspoon salt
  • ¼ teaspoon ground black pepper
  • A few tablespoons chopped fresh parsley, for garnish (optional)

Instructions

  1. Fry the bacon in a large pot over medium heat, stirring frequently, until the fat is rendered and the bacon is crisp, 4 to 5 minutes. Add the olive oil, onions, celery, carrots, and garlic and cook, stirring occasionally, until the onions are soft and translucent, about 5 minutes. Do not brown; reduce heat if necessary. Add the tomatoes (with their juices), broth, lentils, thyme, bay leaves, salt and pepper and bring to a boil. Cover partially, reduce the heat to low, and simmer until the lentils are tender, 45 to 50 minutes (less for common lentils). Fish out the bay leaves and discard.
  2. Use an immersion blender to purée the soup until the broth is slightly thickened, or to desired consistency. (Be careful not to purée too much or the soup will get too thick, and you'll lose the integrity of the lentils.) If you don't have an immersion blender, transfer about 2 cups of the soup to a blender and purée until smooth, then return the blended soup to the pot. Garnish with fresh chopped parsley if desired and serve. (Note: The soup may thicken as it sits; thin with a bit of water if necessary.)
  3. Freezer-Friendly Instructions: The soup can be frozen for up to 3 months. Defrost the soup in the refrigerator for 12 hours and then reheat it on the stovetop over medium heat until hot.

  • Made this today for the first time and it was a hit! My husband doesn’t love soup and he kept saying how good this was. All of my kids gobbled it up. So easy and simple ingredients. Adding this to the regular rotation!

  • This was magical! I couldn’t believe how tasty this was since it’s got such humble ingredients. I found the correct lentils as well, and I’m sure that made a difference. All four of us loved this soup.

    We are loving your recipes, Jenn! Thank you.

  • Made this recipe and it is delicious! I used low-sodium broth AND cut the salt in half (personal preference). I doubled the thyme. Also added a half cup of white wine, to brighten the flavor even more.

    This recipe seems like a great opportunity to up the veggies. I added about 1 1/2 cups of cubed butternut squash, just terrific. I am new to onceuponachef, though now I may become a frequent flier of this website. Thank you for a delicious meal!

  • I love this soup. However, unless you’re using unsalted broth I would recommend omitting the salt altogether, and adjusting the seasoning later, and noting how much salt is needed for next time. Even with unsalted broth, I would half the salt. Otherwise, great recipe.

  • Really, really yummy. My housemate (who’s a very proficient cook) was really impressed!

    Only changes I made were:
    – no added salt (the stock I used was already quite salty)
    – extra thyme – I used half of a dried bunch which I removed before blending.
    – extra blending. I was in the mood for creamy soup, and I love how everything combined to mimic a cheesy flavour.

  • Made this soup vegan for my BFF. Omitted the bacon and just used olive oil. Doubled the carrot and celery and added about 3c of roasted butternut squash, 8c veggie broth, and 1T hot sauce. Pureed the veggie mix after it was cooked, then added and cooked the lentils. For my non-vegan friends served with a splash of crema on top along with the parsley. SO GOOD!!! The french lentils have so much texture which makes this soup interesting. Received RAVE reviews from all. Thank you Jenn!

  • First time cooking lentil soup – perfect instructions & delicious taste!

    For those without the exact French lentils in the pantry (my scenario)- make the recipe anyway.

    Ended up using green lentils instead of French – and we very much enjoyed this. Next time I will make a point to purchase French lentils as you recommend that.

    THANKS JENNIFER

  • This is a simple, healthy, staple recipe. I substitute anchovies for the bacon since I prefer not to eat pork. It adds a layer of umami flavor and depth. I add a bit of red pepper for spice, too! Delicious.

    • Could you please advise how to modify this recipe for people (like my husband) who won’t eat pork? If using anchovies, how many (etc.). Thank you so much, Jenn, for the uncommon care and attention you put into each of your exceptional recipes.

      • Hi Moni, So glad you like the recipes! I’ve never thought about adding anchovies in this but I guess you could. I’d suggest 1 to 2, mashed. You can also either omit the bacon or add a Parmesan rind while the soup is simmering. Hope that helps!

  • Wow…I’ve made lentil soup a lot, but this one was so flavorful! I am a vegetarian, but decided to cook with the bacon anyway. I took the chopped bacon out before adding the veggies and stock. I really think the bacon grease added a certain depth to the flavor of this soup, and my boyfriend got to enjoy extra bacon to add to his bowl :). I also used one small yellow onion and one shallot (all I had on hand). Very good!
    Great recipe!

  • I’ve made this soup countless times. It’s delicious. However, I cut back on the salt (personal taste).
    Today, I had to improvise, as I did not have enough brown lentils left. I added some red lentils about 15 min later, as they cook much faster. It worked fine, and actually saved me the puréing step. 😊

If you scroll down a bit to under the pictures, you’ll find the full recipe. Alternatively, at the very top of the page, to the right of the recipe name, you’ll see an orange/red button that says Jump to Recipe – if you click on that, it will take you directly to the recipe. Hope that clarifies!

  • I made this but was curious why only 1/2 tsp. of thyme for that much soup. I felt it needed more flavoring. Was this a mistake? I also feel it could use more bacon or else my bacon was extremely thin as it looked nothing like the amount of bacon pictured in your photo. I think giving ounces would be helpful.

    • Hi Nanci, The 1/2 teaspoon of thyme is not a mistake. Feel free to add more the next time you make this. And you make a good point about the bacon. I’m going to weigh three slices of bacon and add that to the recipe. Thanks for your input!
