French Lentil Soup with Bacon

Whether you’re looking to eat better in the new year or chase away the winter doldrums (I need to do both), this lentil soup is just the ticket. I love it for its many layers of flavor: the smokiness of the bacon, earthiness of the lentils, and sweetness of the vegetables. The key to success is to use French lentils. These small green lentils hold their shape when cooked and thicken the soup without turning it to sludge (which is, sadly, the fate of most lentil soups).

What you’ll need to make French Lentil soup

You can find French green lentils, or lentilles du Puy, in the bulk section at Whole Foods or other specialty food shops. You can also order them online (affiliate link). They are definitely worth going out of your way to find but if you can’t get them, go ahead and use common green or brown lentils; Just watch the cooking time carefully as they can get mushy. Whereas the French green lentils will need to simmer for 45 to 50 minutes, common green or brown lentils will need just 20 to 25 minutes.

While I love the 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 smoky flavor of the bacon.

How to make French Lentil soup

Begin with the prep. I like to chop the bacon, onions, and celery very fine, so they aren’t too discernible in the finished soup. However, I keep the carrots a bit larger so they don’t disappear.

To make the bacon easy to dice, 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.

Cook the bacon over medium heat until crisp. Don’t be tempted to discard the bacon fat before you add the vegetables to the pot; you’ll need to cook the vegetables and it also adds flavor.

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).

Chockfull of vegetables and bacon, this lentil soup is a hearty and healthy meal unto itself.

Servings: 6
Total Time: 1 Hour


  • 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
  • 1/2 teaspoon dried thyme
  • 2 bay leaves
  • 1 teaspoon salt
  • 1/4 teaspoon ground black pepper
  • A few tablespoons chopped fresh parsley, for garnish (optional)


  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.

  • I am on a journey of trying your recipes and I have not been disappointed at all thus far. The instructions are always clear enough and the pictures you take your time to snap during the process are such a great help! It allows me to see and replicate. This may be one of the aspects that I appreciate most(I am a baby cook). Thank you! 🙂
    Not going to go into details about the lentil soup attempt. The rating already reflects this. A glorious, delicious success!

  • Wow is this soup delicious!! Really! The depth of flavor it has is incredible. I used turkey bacon because that’s what we eat and it was yummy. It was a huge hit with the family including the 13 year old boy so that means it’s really special! This will be my go to lentil soup recipe from now on!

  • loved it..first time i’ve used french lentils and think they are terrific…body and flavor…
    definitely be making it again…didn’t have any parsley on hand but i did have some gremolata that i made previously , hence the the reason i had no parsley and used that for a garnish and it worked really well……. your recipe calls for 3 slices of bacon and that to me was a lttle obscure as bacon slices vary in length from region to region..could you please give us an approximate weight for that ingredient…sorry to be so pedantic but would appreciate it
    thanks so much

  • I was looking up French Lentil Soup and saw you had one, so I had to use yours as most all your recipes are a 5 star. I double it and the only thing different is I add finely chopped kale and 2 teaspoons of smoked paprika and a 1/4 t of hot chile flakes. Now, remember I double this. Yes, this is a 10 star. I am making it for a friend who just came out of the hospital and made extra for my family and so glad I did.

  • I used about 200 g of Speck bacon
    Added pasata instead of chopped tomato
    Minus 1 cup broth
    Added 1/4 tsp celery seed
    Everything else as per recipe/method
    But my twist was add 1 cup medium grain rice with 10 mins cooking time left.
    The dish was transported to the inlaws for easter lunch and let me tell you it stole the show
    Called it a french speck lentil risotto lol
    The kids ate every last bit on their plates.
    Great recipe that is very versatile .
    Thank you
    You literally saved my bacon on easter day !

  • Yumtastic. I had to make do with brown lentils but it was still a hit. (Already ordered les lentilles vertes du puy on Amazon for next time because yes, there will definitely be a next time.) The bacon fat and bay leaves knocked this one out of the park for us. Oven baked the bacon as I find it splatters a lot less and cooks more evenly. (Plus, the oven method doesn’t “baconize” our tiny one bedroom apartment lol.) Used slightly more lentils and slightly less broth as we like a high ratio of vegetables to broth in our soups. For anyone who has to go the common route, I found that 20 minutes of simmer time was ample. Skipped the immersion as we prefer brothy soups. Had a strong feeling we were really going to like this so made a double batch. So glad I did because now some can go into the freezer. Jenn, you’ve become my go-to source when I think “Hmm, I need a recipe for _______.”) I really appreciate your clear instructions and helpful photos. And your responsiveness to those who have questions is impressive. Thank you!

  • Holy bacon! That was definitely the stand out flavour in this dish. I love bacon so I was a big fan. It gave it a nice richness. The pairing of the vegetables, protein and fat made it a well balanced dish in both flavour and substance. I did substitute the chicken stock with veggie and used green lentils (I cooked it for 35 mins since I forgot to check on the lentils). The lentils were still intact but it could have used less cooking time, perhaps 25 minutes. If you live in a wintery climate like me it’s a great soup to make in the colder months. I like using what’s in season, which is sparse in February, so I like using pantry items and this puts them to good use.

  • I have tried to get my husband to try lentil soup before to no avail. This time he came into the kitchen while I was cooking the bacon to ask what I was making. He said he would try it since there was bacon in it. Good thing I doubled the recipe because he had 2 bowls. Perfect for cold snowy weather. The only thing I didn’t double was the salt. Also, pay attention to the blending part, it really does thicken up. Delish. Thanks Jenn.

  • Hi. I made this soup tonight. Although our nights in LA aren’t exactly chilly, they are cool and occasionally gloomy. I loved this recipe because it was easy and nutritious and very delicious. I have never used bacon as a base flavor but it gave a lovely deep smoky flavor to the soup. Served with warm crusty rolls, this soup dinner became a a family hit!

    Do yourself a favor and use the green French lentils. They hold up well in the soup, and have a depth to their favor.

It’s soooo good and I feel like I did something good for my family. Often I skip the bacon and add in other vegetables such as zucchini. I also add in small (cubed) red potatoes as my kids love potatoes.

  • This is the best Lentil Soup recipe ever!!! I serve this soup all the time for “homey” dinner parties and receive compliments and requests for the recipe every time. I make the recipe exactly as Jen wrote it. It is full of flavor and extremely easy to make. Love to keep some in the freezer and heat up for last minute lunches or dinners. A friend who asked for the recipe made it but then called me in a panic because she didn’t have a blender. I told her not to worry, it will taste the same but the consistency will be slightly different. She called later that night and said it came out fine, her kids loved it and never knew the difference.

This time, instead of bacon, which I used to use, I had a ham hock from Christmas that I needed to use, so I threw that in the pot for flavor. I will keep this recipe now on my Pinterest board!
