Hearty Lentil Soup
This post may contain affiliate links. Read my full disclosure policy.
This is the best lentil soup recipe you’ll find—smoky, packed with veggies and hearty lentils for a satisfying, well-balanced meal. Add a slice of crusty bread and you’ve got comfort in a bowl.
Whether you’re trying to eat a little lighter or just want something warm and comforting, this hearty lentil soup really hits the spot. It starts with lots of vegetables and a bit of bacon for depth, but the real upgrade is using French green lentils (lentilles du Puy). Chefs love them for their earthy, peppery flavor and the way they hold their shape as they cook—they give the soup great texture without turning thick or mushy. (They’re also fantastic in lentil salads.)
French green lentils are easy to find in well-stocked grocery stores—places like Whole Foods usually carry them—or you can order them online. If you only have regular brown or green lentils, you can absolutely use them, but the French ones do take it to the next level.
“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 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: Hearty, low in calories, and full of fiber, 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 fresh herbs give the soup delicious, earthy flavors.

Step-by-Step Instructions
Step 1. Crisp the bacon. In a large pot over medium heat, cook the bacon, stirring often, until it’s crispy and the fat has rendered, about 5 minutes.
Step 2. Sauté the vegetables. Add the olive oil, onions, celery, carrots, and garlic. Cook, stirring occasionally, for about 5 minutes, until the onions are soft and translucent.
Pro Tip: Don’t rush this step — let the onions get fully translucent and the carrots start to soften before moving on. Those extra few minutes here mean deeper flavor later.
Step 3. Add the soup base. Stir in the tomatoes, chicken broth, lentils, thyme, bay leaves, salt, and pepper. Bring to a boil, then reduce the heat and simmer until the lentils are tender but not mushy, about 45 minutes (a bit less for common lentils).
Step 4. Partially purée. Use an immersion blender to purée the soup a little at a time until the broth thickens slightly, keeping most of the lentils intact. If you don’t have an immersion blender, blend a few cups in a regular blender and stir it back in.
Step 5. Finish and serve. Season to taste and adjust the consistency if needed, adding a splash of water if it’s too thick (it tends to thicken as it sits). Ladle into bowls, garnish with parsley, and serve. This soup keeps for 3 days in an airtight container in the fridge or can be frozen for longer storage.
Pro Tip: When garnishing with parsley, chop it close to serving time. Pre-chopped parsley oxidizes quickly and loses its fresh, grassy flavor.

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.

This soup was hearty & satisfying. I made it time & a half for more leftovers and was happy with the results.
Made this as specified, but asked myself how many rustic French households had/have immersion blenders. Left it unblended, and it was perfect.
I realize that portions could have been mashed with a fork, etc, but it was VERY good as it was.
With a rustic French baguette, of course.
Hello. I don’t eat bacon. If I omit the bacon in the lentil soup recipe, would I need to add anything else instead, or change the cooking time? Thank you.
Hi Mary, It’s fine to omit the bacon; no other changes necessary. Enjoy!
Made this recipe last night just as listed except using brown lentils (will get the French lentils next time at Whole Foods). Honestly, I was hopeful and cautious at the same time since I had one bad experience with cooking lentils many years ago that did not turn out (texture). I have not made or eaten them since. I suspect in hindsight it was due to cooking them too long (brown lentils). I was hopeful because I have cooked about 7-8 recipes of Jenn’s the last 3-4 weeks that all turned out great, and I really wanted this one to convert me to a lentil soup lover. This recipe turned out fantastic and was so good last night and even better warmed up today for lunch. Thank you, Jenn, for your thorough notes regarding caution about overcooking brown lentils versus the time mentioned for French lentils. I cooked the brown ones about 20 minutes and it was perfect! This is a good basic soup for the season.
If omitting (pork) bacon, would this be better subbing turkey bacon or just without? (Turkey bacon has much less taste/crunch than regular, pork, bacon.)
I’d probably just leave it out, P. You could add a pinch of smoked paprika to replace some of the smoky flavor.
Excellent soup! Thanks so much for the recipe:)
Tried this soup and it is delicious! Added one more piece of bacon and a bit more good olive oil, one more piece of celery. We also used red lentils. Added the lentils to the pot to saute when veggies are almost done. Gives them a bit of smokey flavor due to the bacon. Thank you for this recipe.
I’ve made this several times as my husband and I love soup. The only thing I change is the bacon-I use 5 or 6 slices because we like it a little “meatier”. I make home made cornbread to go with this soup. YUM
Wow! Made this today and it was a hit. My 8 year old daughter loved it and I puréed it fully for my infant who couldn’t get enough! The only thing I changed was the tomatoes- didn’t have any canned on hand so I took 4 Roma tomatoes, emerged them into boiled water, skinned and chopped. Definitely a staple!
So happy to find this amazing recipe. Was looking for something to use the last of my green tomatoes and this was perfect! Followed recipe with the exception of substituting 4 medium green tomatoes for the canned tomatoes. Lovely soup for a chilly, fall day. Served with a drizzle of olive oil and Aleppo pepper and buttered, crusty bread. This is a keeper!
