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.

A double batch of this soup is resting on my stove as i type. I’ll serve it tonight for dinner with a fresh loaf of bread and salad.
I don’t eat meat, so I skipped the bacon and added the extra olive oil as noted to another poster. After the soup was done and partially blended, I did my usual “taste test”.
For me the flavor didn’t bowl me over…perhaps I overcooked? I’m not sure. I wound up adding about a tbsp. more of thyme which improves it, but I’m wondering if the loss of the bacon flavor impacts the result more than thought?
It will be a nice soup (the thyme with lentils has a savory flavor), so it’s not a loss. But it’s not as jazzy as I’d hoped.
Hi Robin, I’m sorry to hear you found the soup a little bland. The bacon does add a lot of flavor but it should still be quite tasty without it from all the vegetables. I’m wondering, did you use regular chicken broth or low-sodium? That would make a big difference. In any case, it may just need salt to bring out all the flavors, or else you could try a dash of smoked paprika to mimic the smokiness of the bacon or a splash of balsamic vinegar (add little by little) to brighten it up.
OMG! Just made this for dinner! It was amazing! My kids were licking the bowl!! So far every recipe I have made has become a family favorite! Thank you for doing all that you do! You have made me a much better cook!!
I really appreciate the initial picture with the ingredients for this reason: I have a really busy schedule, I look at the picture, know I only need to get the Lentils, and then open the entire email when at home and ready to cook. Love it! Thank you
Thanks for the feedback, Kathleen. Good to know!
This was the first time I’ve ever had lentils. The soup had amazing flavor, but the texture was kind of strange. I think next time I’ll blend it a little more. Thanks for a great recipe!
Hi Jessica, You can definitely can play around with the thickness of the soup. I prefer it just slightly thickened, but it’s a matter of personal taste.
Made this tonight and it was fantastic!!! This is a keeper.
I saw this recipe come through my email while I was at work and wanted nothing else to eat for dinner. We just finished eating this for dinner and it was fantastic. The whole family (especially my 5 year old) loved it. My husband is Greek and adds a squeeze of lemon to just about everything. I had my soup without the lemon and had a taste with the lemon. Both were magnificent! Thanks for such a wholesome and delicious meal!
Hi Liz, So glad you all enjoyed. You can also add a splash of balsamic vinegar at the end for a little zing.
Hi Jenn,
I’ve been looking for a good lentil soup recipe and here it is! I bought some the other day but they are “red split” ; the bag gives a cooking time of 12 min. When I make your soup, I’ll let all the flavors meld for awhile and toss in the lentils toward the end. Looking forward to it thank you
Hi Linda, Sounds like a good plan. Please let me know how it turns out.
We are experiencing a “January thaw” in New England, but it is still cold and this soup will be delicious. It is so helpful to see the ingredients you use in the beautiful photos. Like all your recipes, can’t wait to try it. Thank you, Jenn!
Lentils was on my shopping list for this weekend already. I was going to make the Food 52 post for lentil salad, but this looks good too. I’ll have to forego the bacon.
Hi Danita, If you want to leave out the bacon, simply use a few more tablespoons olive oil. It will still be delicious.
Hi Jenn,
I have tried several of your recipes and they have all been great. I made the lentil soup, but did not have the bacon and it was still delicious…Thank you!
The soup looks wonderful, but please note that not all French green lentils are Lentilles du Puy. They must have that marked on the box or package for it to be real. And it makes a huge difference. Coops and Whole Foods sell French green lentils in bulk (at least in the Twin Cities, and they are NOT du Puy.
Hi Susan, Interesting. I’ve found the real deal at my Whole Foods in the DC area. In any case, you can tell authentic lentils du Puy by their color — they’re slate green, marbled with flecks of darker slate blue. They look a whole lot different than common brown, red or green lentils so they should be easy to spot.
