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 are also wonderful when used in lentil salad.)
A bit of bacon infuses the soup with smoky depth, but if you don’t eat pork or would like to make the soup vegetarian, it’s easy to omit. Just add a pinch of smoked paprika at the end for hint of smoky flavor. Either way, you’re in for a bowl of pure comfort.

What You’ll Need To Make Lentil Soup
- Bacon: Adds a smoky depth to the soup’s flavor. To make the bacon easy to chop, wrap the slices 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.
- Onion, celery, carrots, garlic: The classic vegetable base provides sweetness, depth, and aromatics to the soup.
- Canned diced tomatoes: Introduce a slight acidity and richness, balancing the overall flavor of the soup.
- Chicken broth: Serves as the liquid foundation of the soup, offering a rich, savory background. For a vegetarian option, vegetable broth can be used instead.
- Lentils: The star of the soup, lentils are nutritious and hearty, thickening the soup while adding texture and protein. While common brown or green lentils will work, French lentils are preferred for their peppery flavor and firm texture that holds up well during cooking. Unlike dried beans, lentils don’t require pre-soaking prior to being cooked; simply pick over the little legumes, remove any that look broken or damaged, and cook.
- Thyme and bay leaves: These herbs infuse the soup with aromatic, 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.
Frequently Asked Questions
While you can use any type of lentils to make lentil soup, I prefer 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. You can find them in many supermarkets—I usually get them at Whole Foods or Wegman’s—or order them online. They work beautifully in soups as well as lentil salad. If you’d prefer to use common green or brown lentils, that’s fine. Just watch the cooking time carefully as they can get mushy if overcooked.
Yes, this soup can easily be made vegetarian without sacrificing flavor. Simply increase the olive oil slightly to compensate for the absence of rendered bacon fat. Use vegetable broth instead of chicken broth to keep the soup base vegetarian-friendly. To mimic the smoky depth that bacon adds, add a pinch of smoked paprika or a dash of liquid smoke.
Absolutely! The soup can be prepared up to 3 days in advance. Keep it stored in the refrigerator and when you’re ready to enjoy it, reheat on the stovetop over medium heat. If the soup has thickened in the fridge, add a little water to adjust the consistency to your liking.
Yes, lentil soup freezes well and can be stored in the freezer for up to 3 months. To thaw, place the soup in the refrigerator overnight. Then, reheat it on the stovetop over medium heat until warmed through. If necessary, add a bit of water to thin it out if it has become too thick during freezing.

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.

Was so prepared to love this from all the 5* ratings but found it just okay. Followed recipe and used French lentils. They cooked well and had good texture. Thought maybe second day would make it better but can’t say it did. Just seemed like it needed more flavor but can’t decide what. Maybe some heat? Probably will not make again. Usually am pretty happy with recipes I make from Jenn so I will keep trying new ones!
Excellent recipe, my favourite addition is a splash of balsamic vinegar in each bowl,
I love lentil soup and have made another of your recipes for it. Would red lentils work here? I know they cook much faster. Thanks
Delicious! (I used chicken stock from Ina Garten’s recipe and the depuy lentils). Husband is a big lentil soup fan, and said this was the best he’s ever had. Thanks!
This is my absolute favourite soup — quick to make and so satisfying for lunch.
Have made this lentil soup a few times and it is one of the most satisfying and delicious soups I’ve ever had. I even make it for my mother-in-law, who has very high standards and she absolutely loves it. I love Jenn Segal’s fool-proof recipes, they are simple, clear and have worked for me every single time… and even the pictures help me understand what size of produce eg potatoes or onions to use, etc. Make this soup!
We make this soup frequently and it never disappoints. So good with cornbread for a real comfort food night. I do add more carrots and celery for more texture, and have added a bit of fresh spinach when almost done. It’s a favorite for sure.
We loved this soup!! I was very happy that the bacon didn’t over power the other flavors. It just added a nice light smokey component to the soup. I had some older French green lentils that I had to use up, and it took approx 50 minutes for those to soften. This is now my go to Lentil soup recipe!!
What type of meat could I add to give some extra protein?
Thanks, Diane
Pulled rotisserie chicken would be nice.

I adore this recipe. Mr. doesn’t eat soup so more for me. I half the recipe for all but the diced tomatoes. They whole can does in. I prefer Del Monte brand. No peelings like Hunts. I enjoy the peace of chopping the veggies, etc. you never fail to deliver.
