Lentil Soup

Brimming with a wholesome mix of veggies, lentils, and just the right amount of bacon, this hearty lentil soup is the perfect antidote to a chilly day.
Whether you’re looking to eat healthier or beat the cold weather doldrums, this smoky lentil soup teeming with vegetables is just the ticket. It’s a bit more sophisticated than your standard lentil soup, thanks to the addition of bacon and the use of French green lentils, or lentilles du Puy. While common brown or green lentils will work, French lentils are loved by chefs for their earthy, peppery flavor and sturdy texture. They hold their shape when cooked, thickening the soup without turning it to sludge. If you’ve ever had lentil soup so thick you could stand a spoon in it, you will appreciate the difference! (They’re also wonderful when used in lentil salad.)
What You’ll Need To Make Lentil Soup
- Bacon: Adds smoky depth to the soup. Freeze it for 15 minutes before chopping to make it easier to handle. 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 aromatics to the soup.
- Canned diced tomatoes: Lend a slight acidity and richness, balancing the flavor of the soup.
- Chicken broth: Forms the base of the soup. Swap it with vegetable broth if you’re keeping it vegetarian.
- Lentils: Nutritious and hearty, they thicken the soup and add texture and protein. While brown or green lentils work fine, French lentils are ideal for their peppery flavor and firm texture. No need to soak them—just pick out any damaged ones before cooking.
- Thyme and bay leaves: These herbs give the soup delicious earthy flavors.

Step-by-Step 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 until the onions are soft and translucent, about 5 minutes.
Add the tomatoes, chicken broth, lentils, thyme, bay leaves, salt and pepper. Bring to a boil.
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, 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).
Ladle the soup into bowls and garnish with fresh parsley. The soup can be prepared up to 3 days in advance or frozen for longer storage.

Lentil Soup
Brimming with a wholesome mix of veggies, lentils, and just the right amount of bacon, this hearty lentil soup is the perfect antidote to a chilly day.
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
- 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.)
- Note: If using common brown or green lentils instead of French lentils, start checking for doneness around 30 minutes.
- Make-Ahead/Freezing Instructions: You can prepare this soup up to 3 days in advance, or freeze it 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.

This looks yummy! Do you remove the bacon grease after the bacon’s cooked or leave it in the pan before adding the next ingredients? Thanks!
You’ll leave the bacon grease in the pan as that, along with the olive oil, provides something to fry the vegetables in (and adds a lot of flavor). Hope you enjoy!
Jenn this is my favorite of your soups. So delicious eat it all myself. I’m just wondering if you changed the name of it. Is this the same recipe that used to be titled “French lentil and vegetable soup with bacon”? I’ve been following you for years now and have made many of your recipes – all A++! Thank you for making me look like a good cook!
Hi Donna, yes, I did change the name of the soup (and so glad you like this one as well as other recipes)! 😊
I have a kid with new braces who is basically eating through a straw – love all your recipes but wonder if I could use red lentils and just buzz up the soup – I assume it would still taste nice?
Sure, Chrishy – that’ll work fine. Enjoy and good luck with the new braces. 🙂
Thank you! 🙂
Oh my word, this soup is good! My only modifications, I didn’t add the olive oil (just kept all bacon grease), added a pinch of red pepper flakes, used homemade chicken stock, added a pound of ground chicken thigh (cooked) at the end, and didn’t blend the soup. My soup was pretty thick with the addition of the ground chicken. Amazing flavors and so hearty!
This is it!!! I’ve been trying to replicate lentil soup that I had while I was in Canada. Oh my goodness. This soup is so so so good. I’m doubling the recipe to give to a friend. You won’t be disappointed.
Love this soup. We are vegetarian so I omit the bacon. Tons of fiber and so yummy.Lola
How do you tell when lentils are done? Its cooking now so I don’t feel comfortable rating it.
Hi Laurie, I’m obviously weighing in too late to help, but you’ll know the lentils are done when they’re tender (but not mushy). Hope the soup came out nicely!
Easy recipe. I used fire roasted tomatoes and du Puy lentils. Delicious
This was delicious, made it with ham instead of bacon. Thank You!
