French Lentils, Green Lentils and All the Other Lentils

Vive la French lentil difference! French lentils — as opposed to the ordinary brown variety — are smaller and more dense, with a little less starch. French lentils, called de Puy lentils, are a variety of green lentils.

With lentils, the size and starchiness matters and will affect the final lentil soup recipe. When French lentils are cooked, they retain their shape. It is hard for these guys to break down too much, which would otherwise leave you with brown mush. In that way, they are more forgiving than brown lentils. French lentils also have a great nutty flavor.

Is Lentil Soup Good for You?

Like all lentils, these legumes are full of nutrition, loaded with fiber, iron, protein, and more. This lentil soup, which also comes chock-full of vegetables, makes a very nutritious meal.

Lentil Soup: Recipe Notes

  • The base of this French lentil soup combines French lentils with the typical soup “holy trinity” of onion, carrots, and celery. From there things get a little more interesting. Tomato paste adds depth of color and a little acid, while thyme and bay leaves add more aroma and flavor.
  • Finish this soup with a generous dash of red wine vinegar and a knob of good butter. (Or skip the butter to make this a vegan lentil soup recipe!) The vinegar adds brightness and complements the saltier soup base. Butter rounds out the flavor and gives the soup a silky texture.
  • This soup recipe calls for French lentils. That said, regular brown lentils are a fine substitute.

French Lentil Soup

A hearty, easy, vegetarian lentil soup recipe loaded with wholesome flavor. The best lentil soup you'll make, this can also be vegan if you leave out the butter.
Prep Time15 mins
Cook Time1 hr
Course: dinner, lunch, Soup
Cuisine: American, French
Keywords:: easy, French, french lentil soup recipe, lentils, soup, vegan, vegan lentil soup, vegetarian, vegetarian lentil soup recipe
Servings: 3 quarts

Ingredients

  • 2 tablespoons olive oil
  • 1 pound carrots, peeled and chopped
  • 1 large onion, peeled and diced
  • 1 pound celery, peeled and chopped (leafy, pale center stalks removed)
  • 2 tablespoons tomato paste
  • 3 cloves garlic, peeled and lightly smashed
  • 2 bay leaves
  • 1 generous sprig of thyme
  • 1 or 2 fresh parsley stems, with leaves
  • 1 pound French lentils, or regular brown lentils
  • 2 ½ quarts cold water
  • 1 tablespoon kosher salt
  • 1 tablespoon plus 1 teaspoon red wine vinegar
  • 2 tablespoons butter (optional)
  • 12 turns freshly-ground black pepper
  • Pecorino-Romano cheese and freshly-chopped parsley, optional, to finish

Instructions

  • Heat the olive oil in a large soup pot over medium heat. Add the chopped carrots, celery, and diced onion. Cook, stirring occasionally, until the vegetables have slightly softened. Add the tomato paste and garlic and stir constantly (so the tomato paste does not burn) for 2 minutes more. The tomato paste should coat the vegetables.
    TIP: I always buy a tube of tomato paste, not a can. The tube lasts longer, is less messy, and is better for small quantities.
  • Add the French lentils, water, thyme, parsley, and bay leaves. Stir. Bring to a boil, then lower to a generous simmer. Partly cover the soup with a lid and cook, stirring occasionally, for about 45 minutes.
    TIP: If, for some reason, the soup looks too thick, add a little more water and stir it to the right consistency.
  • Add the salt, pepper, red wine vinegar, and butter (if using). Taste for seasoning.
  • Fish out the bay leaves and thyme and parsley stems. Ladle into bowls and serve with grated pecorino-Romano cheese, minced parsley, and some good crusty bread.

Notes

Lentil soup can be frozen for up to several months. Thaw overnight in the fridge, or right into a pot with a little water at the bottom so it does not scorch.

    I thinned it with a little more water like the recipe suggested. delicious. The red wine vinegar and butter does add just the right hint of something!

    I have a question rather than a comment at this time.
    Can this soup be frozen successfully? Or should I make half a recipe as this would be way too much for a household of two.

    Thanks

    Turned out very well. I agree with the other comment that the vinegar and butter at the end is a nice touch.
