This hearty lentil soup will chase away the chill.

Whether you’re looking to eat better or chase away the cold weather doldrums, this smoky lentil soup with vegetables is just the ticket. It is best made with 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, thickening the soup without turning it to mush (if you’ve ever had lentil soup so thick you could stand a spoon in it, you know what I mean). You can find French green lentils in many supermarkets—I usually get them at Whole Foods or Wegman’s—or order them online. They are worth going out of your way to find, as they work beautifully in soups and salads. If you can’t get them, it’s fine to use common green or brown lentils; just watch the cooking time as they can get mushy.

Unlike dried beans, lentils don’t require pre-soaking prior to being cooked. You simply pick over the little legumes, remove any that look broken or damaged, and cook.

What you’ll need to make Lentil soup

While I love the smoky flavor that bacon lends to this soup, if you don’t eat pork or are a vegetarian, you can omit the bacon. The soup will still be delicious but you might add a pinch of smoked paprika to mimic the flavor of the bacon.

Step-by-Step Instructions

Begin with the prep. To make the bacon easy to chop, wrap the slices you need 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.
Chop the bacon, onions, and celery very fine, so they aren’t too discernible in the finished soup, but keep the carrots a bit larger so they don’t disappear.

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.

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, simply 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).

Servings: 6
Total Time: 1 Hour

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

  1. 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 (less for common lentils). Fish out the bay leaves and discard.
  2. 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.)
  3. Freezer-Friendly Instructions: The soup can be frozen for up to 3 months. Defrost the soup in the refrigerator for 12 hours and then reheat it on the stovetop over medium heat until hot.

  • I changed mine up a little. Didn’t have diced tomatoes so I diced a fresh one and added some tomatoes paste. I added cubed potatoes. I added 2.5 cups lentils and didn’t use the emulsion blender. Mine turned out more like a delicious lentil stew. Thanks!

  • Jenn does it again! I loved this lentil soup, and it was so easy to make. I didn’t have thyme, so I left it out, and the soup was still scrumptious.

    I also liked how simple it was to halve the recipe. It’s just me, myself, and I, so a serving of 3 was perfect haha!

  • I have made this many times now, best lentil soup!!! Made it for a chef friend as he was laid up with a broken ankle, I was a bit nervous as he is one of the best chefs I know. He (not just being nice) said it was the best lentil soups he has had. The only thing I did difference is added a little smoked paprika and some kale. I would love if you added the ingredients also in oz’s or grams in some cases like herbs.
    PS
    If I am looking for a recipe and your name is next I know it’s going to be a winner.

    • So glad it was a hit with your chef friend! And the great majority of my recipes (including this one) include conversions to metric/weight measurements. To view them, scroll down to the recipe, and immediately under the recipe title on the right side, you’ll see a little toggle. If you move it from “cup measures” to metric, you’ll see measurements that will work for you.

  • Made it today for dinner. We had it with crumbled turkey bacon (the only kind I had). Delicious!

  • To cut back on prep time, I cut the bacon with kitchen shears and use a bag of baby spinach. I also separate the bacon into groups of three and freeze them for future use. I sub a can of fire roasted diced tomatoes to add a hint of smoke. Best lentil soup recipe, period!

  • I made this for the first time tonight, and it is delicious! I used plain dried lentils. The package said to cook for 15-20 minutes. I let the soup simmer for 30 minutes, and that seemed just right. Thank you for the note that plain lentils take less time to soften. I also added a little extra bacon (and no salt) to the recipe. Yummmm!

  • Perfect soup. Love lentils and this was delicious as is. One comment: I did not add any extra salt, since I use Better Than Bouillon Chicken stock and it’s very concentrated.

  • So good! Followed recipe exactly except I didn’t puree the lentils because we like chunkier soups. This is a keeper and I will make it again and again.

  • This lentil soup recipe is amazing! It’s easy and packed with good things. I used Costco bacon bits in lieu of cooking bacon slices. Your website is amazing and your recipes are easy to follow. Thank you!! Sally
