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.

This recipe is perfect, the only change I made is to omit the salt, i use Better than Bouillon chicken broth and it was salty enough. Excellent soup that s very filling!
that would be a good replacement for the bacon to make this recipe vegan?
Hi Alex, It’s fine to just leave it out but you’ll need to use a bit more oil. Enjoy!
While lentil is my soup of choice, I did not care for the flavor of bacon with the lentils nor the texture of the bacon after simmering in the soup. The one substitution I made was to use a sweet potato in place of carrots. I freeze several jars of soup to have on hand for quick soup and sammie dinners. A note for those who freeze soup: the bacon did not freeze well. Upon reheating it floated limply on the top. I prepare this soup several times a month minus the bacon and find it to be delish.
I have similar feelings about the texture of crisped bacon that is then simmered or braised, but have had a lot of success removing the cooked bacon when it’s crisp and using as a garnish when serving the soup. You get the lovely smoky flavor of the bacon fat for sauteeing the vegetables and preserve the texture of the bacon.
This is a hearty soup, but we made this tonight as a starter to mushroom risotto, seared scallop and pancetta, and tender sugar snap peas. Delicious!!! We’ve never had lentil soup before; not sure why not. But based on the reviews I could not resist trying this soup recipe. I’m so glad I did! We’ll be eating this soup all the weekend long in-between our outdoor winter activities. Every recipe of yours I try, Jenn, makes me that much more excited for your recipe book!
😊
I really enjoyed this recipe. I used a double smoked bacon and found that Canadian lentils work just fine (they do not go mushy). Other tweaks were a couple of splashes of scotch bonnet sauce and a teaspoon of anchovy sauce; both to further enhance flavour!
This was the best lentil soup I’ve ever had! My whole family loved it. I didn’t have chicken broth, but beef tasted great, too.
Thanks for another delicious winter supper idea!
For those of us that don’t eat pork, how might you modify this recipe, so we don’t loose the flavor provided by the bacon? Thanks so much!
Hi Danielle, you can use turkey bacon or just omit the bacon. It’ll still be delicious!
Hi do you typically prefer to use the long carrots or the smaller baby carrots?
Hi Kim, I prefer long carrots. Enjoy!
My husband’s Italian Nonna does not speak English but she taught me to make her lenticchia soup years ago, she did not measure anything though (of course) and I wish I took better notes. I tried this recipe and it’s definitely close, a little different but I finally have clear instructions to follow for something similar. This is a delicious soup, another great recipe from this site. I modified slightly only to make it a little more like Nonna’s version: I blended the tomatoes mostly at the thickening step because she used a smooth tomato sauce, I used thick cut bacon and more of it, and instead of garnishing with parsley, I garnished with a drizzle of olive oil and freshly grated Parmesan – all minor adjustments. Make sure to serve this one with a delicious crusty bread. When reheating leftovers, add a little water and olive oil. And, if you like this one, you have to try Jenn’s Pasta e Fagioli – my husband constantly requests it, I’m making it for the hundredth time tomorrow night. Buon appetito!
This soup is absolutely soul warming goodness. Nothing would be better on a chilly night. The only changes I made were to add a can of fire roasted tomatoes and 3 sprigs of fresh thyme because I had them on hand. Thank you again Jenn!
