This cozy Italian-inspired lentil soup recipe is easy to make, full of feel-good ingredients, and always so flavorful and comforting.

Italian Lentil Soup

This Italian lentil soup is one of those back-pocket recipes I find myself defaulting to again and again because it calls for super-basic ingredients that we almost always have on hand. And on chilly nights when we find ourselves craving some feel-good vegetarian comfort food, it’s one of those simple recipes that always always hits the spot. ♡

It’s made with a basic mix of veggies and protein-rich lentils, all simmered together in a tomato-herb broth with a slight kick. Then once the lentils are cooked and tender, I always stir in a few handfuls of kale (or whatever greens happen to be hanging out in the crisper drawer) and some extra fresh basil (if you happen to have some on hand), and then finish off each serving bowl with a generous sprinkling of freshly-grated Parmesan and a few twists of black pepper. It’s one of those simple soups that somehow always tastes even better than we remember and — bonus — also makes for amazing leftovers the next day.

So round up those leftover lentils that have been sitting in the back of your pantry and let’s cook up a big pot of lentil soup together!

Italian Lentil Soup Ingredients

Italian Lentil Soup Ingredients

Before we get to the full lentil soup recipe below, here are a few quick notes about the ingredients you will need:

  • Mirepoix: We’ll use the classic trio of onion, carrots and celery as the base for this soup, sautéed in olive oil to soften.
  • Garlic: Lots of fresh garlic, either pressed or minced, to season the broth.
  • Broth: I usually make this soup with vegetable broth, to keep it vegetarian. But chicken or beef stock would work well here too.
  • Lentils: I recommend basic brown or green lentils for this soup, which cook up in around 30 minutes. But other varieties of lentils (red, French or black) could also work in this soup, if you adjust the cooking time as needed.
  • Diced tomatoes: I recommend fire-roasted diced tomatoes to add an extra layer of roasted flavor to the soup, but basic diced tomatoes will work just fine too.
  • Seasoning: This recipe uses a simple pantry mix of bay leaves, Italian seasoning, crushed red pepper flakes, fine sea salt and freshly-ground black pepper. But if you happen to have fresh Italian herbs on hand, feel free to add them to taste in place of the Italian seasoning.
  • Greens: Chopped fresh kale, collard greens or baby spinach are all great options for the greens here.
  • Basil: I like adding a generous amount of fresh basil to the soup, plus adding some as garnish to each of the serving bowls.
  • Parmesan: Finally, I highly recommend serving each bowl with a generous amount of freshly-grated Parmesan on top. And if you happen to have a leftover Parmesan rind on hand, be sure to add it to the broth as it cooks too for an extra flavor.

Recipe Variations

Here are some other variations you’re welcome to try with this lentil soup recipe:

  • Add a protein: Add Italian sausage, ground beef, or shredded chicken.
  • Add extra veggies: Add bell pepper, fennel, green beans, potato, sweet potato, zucchini or other soup-friendly veggies.
  • Add pasta: Add 1 cup ditalini (or another small pasta shape), along with an extra 2 cups of broth, about 10 minutes before the lentils have finished cooking. You’ll likely need to adjust the amount of seasonings to compensate for the extra broth too.
  • Make it spicier/milder: Use more or less of the crushed red pepper flakes, to taste.
  • Make it vegan: Just omit the Parmesan to make this vegan lentil soup. (You’re welcome to add some plant-based Parmesan or a sprinkling of nutritional yeast, if you’d like.)
