The best lentil soup recipe you’ll find—smoky and loaded with bacon, vegetables, and French green lentils for a satisfying, well-balanced bowl. Pair with crusty bread for the perfect meal. Whether you’re looking to eat healthier or curl up with something warm and comforting, this lentil soup filled with vegetables is just the ticket. It’s a step up from the everyday version, thanks to bacon and French green lentils, or lentilles du Puy. Loved by chefs for their earthy, peppery taste and firm texture, French lentils hold their shape beautifully as they cook, giving the soup substance without turning thick or mushy. (They’re also wonderful in lentil salads.) Common brown or green lentils will work, but French lentils make this recipe extra special. “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. Jump to the printable recipe for precise measurements Bacon: Adds smoky depth to the soup.

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.

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.
