Lentil Soup

This easy lentil soup recipe turns a handful of humble ingredients into a deeply flavorful and satisfying meal.
Many lentil soup recipes veer into porridge territory, but I prefer mine hearty without being so thick you could stand a spoon in it. Using French green lentils makes all the difference. They hold their shape beautifully as they cook, giving the soup plenty of texture without turning mushy. At the end, I also partially purée the soup—just enough to give the broth some body while leaving most of the lentils and vegetables intact.
For flavor, a little bacon adds smoky depth, while plenty of vegetables make it satisfying without feeling heavy. The result is a richly flavored lentil soup with great texture in every spoonful. Add some crusty bread on the side, and dinner is done.
“Husband is a big lentil soup fan, and said this was the best he’s ever had.”
What You’ll Need To Make Lentil Soup
- Bacon: Adds smoky, savory depth to the broth. You only need a few slices; the idea is to flavor the soup rather than make it bacon-heavy. For a vegetarian version, skip the bacon and add a pinch of smoked paprika for that hint of smokiness.
- Onion, celery, carrots, garlic: The classic veggie base adds sweetness, depth, and flavor to the soup.
- Canned diced tomatoes: Add acidity and a little sweetness, balancing the earthy lentils and smoky bacon.
- Chicken broth: Forms the base of the soup. Swap it with vegetable broth if you’re keeping it vegetarian.
- Lentils: My first choice is French green lentils, which are available at well-stocked grocery stores or online. Common brown or green lentils also work, but they’ll soften a bit more. Avoid red lentils, which will give the soup a very different texture.
- Thyme and bay leaves: These herbs give the soup delicious, earthy flavors.

How To Make Lentil Soup
Cook the bacon and vegetables: Cook the bacon until crisp and the fat has rendered, then add the onion, celery, and carrots and cook until softened. Stir in the garlic and cook briefly until fragrant.
Simmer the soup: Add the tomatoes, broth, lentils, thyme, bay leaves, salt, and pepper. Bring to a boil, then reduce the heat and simmer until the lentils are tender but still hold their shape. The cook time will depend on the type of lentils you use; French green lentils take a little longer than common brown or green lentils, so use the texture—not just the clock—as your guide.
Partially purée and finish: Remove the bay leaves, then use an immersion blender to partially purée the soup, leaving most of the lentils and vegetables intact. This thickens the broth and gives the soup body without making it completely smooth. Taste and adjust the seasoning and consistency as needed—you can add a splash of water if the soup is too thick.
No immersion blender? Transfer a few cups of the soup to a regular blender, purée until smooth, then stir it back into the pot.
Serve: Ladle into bowls, garnish with parsley, and serve. This soup well for several days in the fridge or can be frozen for longer storage.

Lentil Soup
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 freshly ground black pepper
- A few tablespoons chopped fresh parsley, for garnish (optional)
Instructions
- 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 (see note on cooking time if using common brown or green lentils). Fish out the bay leaves and discard.
- 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.)
Notes
- If using common brown or green lentils instead of French lentils, start checking for doneness around 30 minutes.
- Make-Ahead/Freezing Instructions: The soup can be prepared up to 3 days in advance, or frozen for up to 3 months for longer storage. To defrost, let the soup thaw in the refrigerator overnight. When ready to serve, reheat the soup on the stovetop over medium heat until it's thoroughly hot. If you find the soup has thickened more than you'd like during its time in the fridge or freezer, simply stir in a little water or broth to reach your desired consistency.

How would I make this in an Instant Pot?
Hi Colleen, I don’t have an Instant Pot so don’t have enough experience to guide you, but another reader commented that she made the soup using one and provided the following guidance: You can saute all the ingredients as written in the pot and then instead of boiling it, use high pressure at 18 minutes (range was between 15-20 minutes) if you are using the common brown/ green lentils. I let it naturally release for 10 minutes. Took out some of the soup and blended it and poured it back in. We have a 6 quart pot.
Hope it helps and that you enjoy the soup if you make it!
Made this soup today and it was very tasty. Perfect for a winter day. I will be making this again. Thank you for the recipe.
Good morning Jenn. I received your email with this recipe this morning. It immediately had me running to my silverware drawer as I thought the pattern of the spoon you had in the picture of the soup was the same as what I grew up with. I compared mine to yours and it is exactly the same pattern!! I started crying as it brought up so many memories. This was a lovely way to start the day!!
I’m giving you 5 stars because every recipe I’ve made of yours is 5 stars and beyond!!
❣️
Never without a container of this in the freezer for those days wanting comfort and warmth.
Great recipe!
Fantastic. Thank you. Went across the street in my robe to get bay leaves off the neighbour’s tree. Thyme from my own garden. Made a smaller amount but flavours are perfect. ❤️
Hi Jenn – quick question. What are your thoughts on kielbasa instead of bacon?
Thanks. Chuck.
Sounds yummy!
And indeed it was yummy. Sautéed about 6 oz kielbasa, removed from pot, then added back after immersion blending. Great flavor.
good to know – thanks for following up!
Another outstanding Jenn recipe!
This is one of a few lentil soup recipes I like to make, and it is a good one. Hearty, savory and comforting. We like to do occasional soup and sandwich nights, and coming up with complimentary and tasty pairings is fun. We had this soup with smoked turkey, boursin, plus dijon mustard and romaine on sourdough bread. My other recipes are typically slow cooked to make the lentils edible. I like that the red lentils cook so quickly in this version.
This soup hits!
Follow the recipe exactly and use French lentils.
I’ve made this many times as is and turned out great! Only had beluga lentils in the pantry this time and I can tell ya, they do not have enough lentil to them to make it substantial! I screwed up so you don’t have to!
