Why You’ll Love This Easy Soup

  • Cozy and Complex. Like all of my best soup recipes, this one starts with aromatic vegetables and herbs at its base, slowly sautéed to build complex flavor.
  • Budget-Friendly. Lentils, canned tomatoes, and carrots are all inexpensive ingredients, making this an excellent budget recipe.
  • Healthy. Lentils are a powerhouse of vitamins, protein, and fiber. This soup contains a colorful mix of veggies, providing diverse vitamins and delicious flavors to boot.
  • One-Pot Winner. Is it just me or does dinner taste better when there are fewer dishes to wash? If you agree, check out more of my one-pot recipes.
  • Plant-Based Power. Looking to cook meatless meals more often? Lentil soup is a filling vegetarian recipe that satisfies meat-eaters too.
  • Freezer-Friendly. This recipe yields a generous batch. Future you will thank current you for freezing portions for fast, healthy dinners to come.

How to Make Lentil Soup

The Ingredients

  • Veggies. The holy grail of slowly sautéed onions, garlic, and carrots.
  • Herbs and Spices. Fresh thyme and bay leaf enhance the earthiness of the lentils and overall warmth of the dish.
  • Tomatoes. Bust out those pantry staples; it’s soup season. The tomatoes add to the broth flavor and liquid needed to cook the lentils.
  • Lentils. Quick-cooking, inexpensive, and nutrient-packed, lentils are a staple food all around the globe. This soup works well with brown or green lentils (also called lentils de Puy).

Ingredient Note

Use your remaining lentils for Instant Pot Lentil Curry or Lentil Meatballs.

  • Broth. Vegetable broth keeps this dish vegetarian, but chicken broth could be used otherwise. Use low sodium to keep the soup from getting too salty.
  • Kale. A sturdy leafy green, it is ideal for soups because it holds up to simmering. If you have nutritious kale leftover, make this Kale Soup!
  • Sherry Vinegar. One of the final notes that really brings this soup symphony to life.

Substitution Tip

Red wine vinegar can be used in place of sherry vinegar.

  • Red Pepper Flakes. Optional for a bit of heat.
  • Honey. To balance out the acidity and round it all out.
  • Parmesan. Freshly grated Parmesan is stirred in at the end to add some creamy, cheesy delightfulness, plus more to top your bowl and make you smile and feel fancy. To make the lentil soup vegan, simply omit it.

Recipe Variations

  • Mediterranean. Swap the thyme for a handful of fresh parsley, and add ¼ teaspoon turmeric or coriander and 1 teaspoon of cumin to taste; omit the Parmesan.
  • Indian. See my Curried Lentil Soup.
  • With Sausage. Start the recipe by browning 1 pound of ground Italian sausage (or turkey sausage). Remove to a plate, then stir back into the soup at the end.
  • With Bacon. Cut bacon into pieces, and start the recipe by browning the bacon in your pot. Once cooked, remove the bacon to a plate, then add it back in at the end. Saute the vegetables in the bacon drippings.

Storage Tips

  • To Store. Lentils soup will last for up to 5 days in refrigerator, stored in airtight container. 
  • To Reheat. Reheat in Dutch oven on stove on medium-low heat until hot, or in microwave.
  • To Freeze. Great for a freezer meal, this soup can be stored in airtight, freezer-safe storage container (I love using Ziplock bags and laying them flat to freeze) for up to 3 months. Let thaw overnight in the refrigerator before reheating.

Meal Prep Tip

Veggies can be prepped in advance to save on cooking time the day of. Peel and chop carrots and garlic, then store in container in fridge the day before cooking the lentil soup.

What to Serve With Lentil Soup

While the soup in itself is a complete and filling meal, a salad and/or bread would make for a classic combo.

  • Dutch Oven. My most treasured kitchen tool. This is also a great option and easier on the wallet.
  • Wooden Spoon. My preferred tool for sautéing and stirring.
  • Ladle. Serve it up!

Recipe Tips and Tricks

  • Pick the Right Lentils. For soup, choose firmer lentils that hold their shape during a longer simmer time, such as brown or green lentils (also called lentils du Puy). Red lentils and yellow lentils are very delicate, so while they are great for Indian curries like dal, they become mushy in soup and are less desirable.
  • Rinse the Lentils. Lentils must be rinsed before cooking to remove any dirt. Pick out any debris too.
  • Don’t Rush the Onions or Tomatoes. Be patient with the onions’ sauteing time and the tomatoes’ simmering time; this is key to the soup’s flavor.
  • Use What You Have. Feel free to add or subtract vegetables based on what you have on hand or prefer. Celery could be added to the base, or spinach could be swapped for the kale, for example.
  • Parmesan Rinds. Keep them in the freezer, then add one to the soup while it simmers for a richer, more complex flavor; remove before serving.

The best lentil soup recipe! Healthy, comforting, and satisfying, it's loaded with flavor, cooks fast, and is a family-friendly budget meal.

Prep: 15 minutes
Cook: 45 minutes
Total: 1 hour

Servings: 6


  • 3 tablespoons extra-virgin olive oil
  • 1 medium yellow onion cut into ¼-inch dice
  • 6 garlic cloves minced (about 2 tablespoons)
  • 4 sprigs fresh thyme tied together with kitchen twine (or 1/2 teaspoon dried)
  • 1 teaspoon kosher salt
  • 1/4 teaspoon ground black pepper
  • 4 medium carrots scrubbed and cut into ½-inch dice (peeling is optional)
  • 1 15-ounce can fire roasted diced tomatoes in their juices
  • 1 15-ounce can crushed tomatoes
  • 1 cup brown or green lentils rinsed with any shriveled lentils discarded
  • 4 cups low sodium vegetable broth
  • 2 bay leaves
  • 1 1/2 cups stemmed and chopped kale
  • 2 teaspoons sherry vinegar or red wine vinegar
  • 1 teaspoon honey or granulated sugar
  • 1/8 teaspoon red pepper flakes optional
  • 1/4 cup finely grated fresh Parmesan plus additional for serving (omit or swap nutritional yeast to make vegan)


  • In a Dutch oven or similar large, sturdy soup pot, heat the oil over medium low. Add the onion. Cook, stirring occasionally, until the onion is very soft and turning browned, about 10 minutes.
  • Add the garlic, carrots, thyme sprigs, salt, and black pepper. Cook until the carrots are barely soft, 2 to 3 minutes. Add the diced and crushed tomatoes, bring to a simmer over medium-high heat, and let simmer 2 minutes.
  • Add the lentils and stir to coat. Add the broth and bay leaves. Increase the heat to high and bring the mixture to a boil, then partially cover the pot and lower the heat to a gentle simmer. Let simmer, adjusting the heat as needed so the lentils simmer gently but do not boil, until the lentils are tender but not mushy, about 25 minutes. Fish out and discard the bay leaves and thyme bundle.
  • With an immersion blender, puree the soup briefly to thicken it up a little but leave plenty of the lentils and vegetables intact (or you can transfer about 2 big ladlefuls to a blender, puree, then return to the soup).
  • Stir in the kale, vinegar, honey, and red pepper flakes. Partially cover the pot, and let cook over low until the kale is tender, about 5 to 7 minutes. Stir in the Parmesan. Taste and adjust the seasoning as desired. Enjoy hot with a sprinkle of Parmesan.



  • TO STORE: Lentils soup will last for up to 5 days in refrigerator, stored in airtight container. 
  • TO REHEAT: Reheat in Dutch oven on stove on medium-low heat until hot, or in microwave.
  • TO FREEZE: Great for a freezer meal, this soup can be stored in airtight, freezer-safe storage container (I love using Ziplock bags and laying them flat to freeze) for up to 3 months. Let thaw overnight in the refrigerator before reheating.
TIP! Have an extra Parmesan rind? Add it with the broth and simmer as the lentils cook.

Frequently Asked Questions

Can I Use Dried Thyme Instead of Fresh?

Because this simple lentil soup has so few ingredients, I recommend using fresh thyme for the best flavor. If you cannot use fresh, swap 1/2 teaspoon dried thyme.

Is Lentil Soup Gluten Free?

Yes! Lentils are a legume and do not contain gluten.

Do I Need to Soak Lentils to Make Lentil Soup?

No. You do not need to soak the lentils before adding them to the soup. Lentils are quick-cooking and don’t need a presoak the way more hearty legumes like beans do.

Are Lentils Good Luck?

If you are Italian, you might think so! Italians have a tradition of eating lentils on New Year’s Eve for good luck. With the flat legumes said to resemble Roman coins, eating lentils was thought to bring wealth and prosperity. So if you are in Italy, or want to pretend you are, this lentil soup recipe would be a wise choice for New Year’s Eve!

  1. Outstanding recipe and one that we’ve been making on repeat! Perfect for the colder months. Love the flavor that the fire-roasted tomatoes contribute, and it’s heavenly with parmesan as you recommended! Another healthy and delicious recipe to add to our rotation. Thank you Erin! :)5 stars

  2. Haven’t made it yet but can tell it will be outstanding. I know the base recipe is super healthy … but the idea of some bacon really sounded like a natural to me and I may opt to cheat a little. Curious Erin … if I opt for bacon, how much do you think would be a good amount?

    1. Hi Bill! Sounds tasty! Maybe about 4 slices? If you decide to experiment with bacon, I’d love to know how it goes!

  3. Flavors were amazing. Left it vegan for our daughter and added the Parmesan individually to our bowls. I think my lentils might have been old, because it took over 90 minutes for them to get Al dente. I probably will soak first next time, since the bag I had in the pantry is very large. Will definitely make again!5 stars

  4. This looks delicious! How do you think it would turn out if you skip the immersion blender step?
