This is the best lentil soup recipe I’ve ever tasted!
Plus, it’s easy and quick enough for a weeknight meal.
It’s quick, has the most delicious flavor, AND is packed with vital nutrients. What’s not to love?!
Lentil soup is incredibly easy to make and so inexpensive. It is seriously one of my favorite main dishes to make for a quick dinner.
Even with organic ingredients, you can make a giant pot of soup that will feed 6-8 people for less than $10. Sign. Me. Up!
What are lentils? Lentils are legumes, similar to peanuts and soybeans. The pulse (dry, edible seed) is what we traditionally think of as a lentil.
Lentil Soup Benefits
Lentil soup combines the nutrients, protein, good carbohydrates, and fiber in lentils with the antioxidant power of veggies, herbs, and spices. Adding a little healthy fat from the extra virgin olive oil rounds it out into a perfectly balanced meal.
Lentils are especially high in B vitamins and minerals like iron, phosphorus, potassium, calcium, and zinc. This soup recipe is also low in sodium and contains little-to-no saturated fat.
In fact, many nutritionists consider lentils one of the healthiest superfoods that you can eat, especially on a tight budget.
Lentil soup is so flexible and can be made in a huge variety of ways. While I prefer to make this soup on the stovetop to bring out each ingredient’s flavor while sauteing, you can just throw it all in a slow-cooker and come home to a great meal.
When paired with the other ingredients and optional vegetables, this lentil soup is packed with vitamin A, B vitamins, and dozens of minerals. I call that a win!
How to Choose Your Lentils
I like to use the small dark green lentils (aka French lentils) because they’re sturdy and cook quickly. Regular green lentils are also fantastic here (I buy mine on Thrive Market at a great price.)
All lentil varieties work great in this recipe and are very nutritious, so try different types (red, green, etc.) and find what you like best.
Red lentils cook down extra soft, while green and black lentils will hold more bite. Brown lentils also cook quickly but lose their shape more than green lentils, resulting in a more mushy soup.
To Soak or Not to Soak Lentils?
Do lentils need to be soaked? Unlike other pulses, it’s not necessary to soak lentils before cooking them. You may still choose to soak them for benefits to the cooking time or to make them easier to digest. Really, it’s up to you.
Lentils need a little more cooking time if you don’t soak them, but it’s generally not a problem. If you haven’t had time to think ahead, still give them a good rinse in a fine-mesh colander and inspect them for any hard shells or rocks, as lentils are stored in big drums and can accumulate dust particles. But i’s totally ok if you don’t have time to soak them.
On the flip side, lentils will cook faster if you soak them. Soaking lentils can also make them easier to digest. If you find that lentils make your tummy grumble or give you gas, then consider soaking them for 12-24 hours.
Always discard the soaking water and rinse the lentils before proceeding with cooking.
Are Lentils Gluten-Free? Lentils are naturally gluten-free. However, always make sure to read your labels—some lentils may be processed in a facility that processes items with gluten.
Recipe Variations
Think of this lentil recipe as a guide and method to making lentil soup— it’s absolutely delicious as written—and super flexible, too.
Feel free to add any herbs, spices, or veggies that you’d like and make it your own. A squeeze of fresh lemon juice to finish it off is really nice in lentil soup.
If you’re adding extra veggies or greens like kale or spinach, add an extra 1/3 cup of liquid for every 1/4 cup of veggies you add. You can also eye it and add liquid (water or stock) as needed.
I love to make a side dish of cornbread or crusty bread to go with this lentil soup recipe, which pairs beautifully.
Here are a few ideas on how to customize this lentil soup:
Make It Vegan
To make this recipe a completely vegan lentil soup, simply substitute the chicken broth for vegetable broth or vegetable stock.
Up the Protein
Use protein-rich bone broth (aka long-simmered chicken stock) to add even more protein to this dish. You can make your own, which takes 12-48 hours, or find it at most grocery stores.
How to Add More Flavor
If you aren’t looking for a vegan dish, in particular, a quart of chicken stock deepens the flavor of this dish (I recommend it!). You can find quarts of high-quality chicken stock at just about any store. I prefer organic, but choose what you can.
Tip for Making the Best Lentil Soup
There is honestly no perfect way to make this soup, and that is what I LOVE about it. However, I have found a handy tip for making this the best lentil soup:
Do not overcook the lentils.
Whether this is your first time making lentil soup or your thousandth time, I cannot stress this enough. Make sure to not overcook the lentils, or else they will become extremely mushy.
That will not affect the taste of this yummy soup, but the mushy lentils thicken the soup and give it a different, less pleasant consistency.
Make It in an Instant Pot or Slow Cooker
I like this recipe best on the stovetop because following each individual step brings out the most flavor from each ingredient.
However, if you’re in a rush, toss all of the ingredients into a slow-cooker or pressure cooker (I love my Instant Pot for times like this) and set it on low for 5-6 hours or high for 3-4 hours. Blend part of the soup if desired before serving.
Storage
Make your soup in a large pot or Dutch oven, then let is come to room temperature to store. Store it in an airtight container in the fridge for up to 4 days, then freeze it after that for up to 3 months.

Ingredients
Scale
- 1-quart vegetable stock (or chicken stock or bone broth or filtered water)
- 2 cups filtered water
- 1 1/2 cups lentils, rinsed (soaking is optional)
- 3 tablespoons extra virgin olive oil
- 1 small yellow or white onion, finely chopped
- 2 celery ribs, finely chopped
- 1 large carrot, finely chopped or grated
- 3–4 cloves garlic, finely chopped or pressed
- 1 teaspoon ground cumin
- 1/2 teaspoon dried oregano
- 1 bay leaf
- 1 tablespoon red wine vinegar (aged balsamic also works)
- 1 teaspoon sea salt (I use Real Salt), more or less to taste
- 1/2 teaspoon freshly ground black pepper (about 5 spins in a pepper grinder)
- Optional: 2 tomatoes, seeded and chopped (or one 12 oz. can of organic diced tomatoes)
- Optional: Any greens you’d like to add, look for something in season and at a reasonable price at the store. Spinach is always a great option and has a mild flavor. We like 1 handful of greens per serving.
Instructions
- Spread the lentils out on a large sheet tray and pick out any debris (aka anything that doesn’t look like a lentil). Legumes are harvested and stored in large quantities, and sometimes little rocks or other things make their way in the bag.
- Rinse your lentils well in a fine-mesh strainer before using them.
- If you choose to pre-soak your lentils (I don’t, but many people do):
- Pour the lentils into a large bowl and cover with purified water by 2 inches.
- If you’ve thought ahead enough, cover the bowl with a kitchen towel and leave it on the counter for 12-24 hours.
- Drain the lentils and rinse them well before using them.
- Heat the olive oil over medium heat in a large soup pot or Dutch oven.
- Add the chopped onion, carrot, and celery with a big pinch of sea salt and cook until tender, about 5-6 minutes.
- Lower the heat down to medium-low (to prevent the garlic from burning) and add the garlic, cumin, oregano, another pinch of salt, and a few spins of freshly ground black pepper.
- Stir and let cook another 2-3 minutes until the mixture is very fragrant. (Be careful not to burn the garlic—turn the heat down to low if necessary, as garlic burns easily.)
- Add the bay leaf, 1 teaspoon of salt, a few more spins of black pepper, stock, water, and rinsed lentils to the pot and bring to a full boil, then reduce the heat to a simmer. The amount of salt you need will depend on what type of stock you use; start with one teaspoon and add more later to taste if desired. If your stock is not salted, you may need up to 2 (or more) teaspoons).
- Add the tomatoes (if using).
- Let the pot simmer for about 40-50 minutes or until the lentils are soft.
- Once the lentils are tender, turn off the heat and stir in the vinegar.
- Discard the bay leaf before pureeing and serving.
- Depending on how you like the texture, use a handheld immersion blender to blend 1/3 to 1/2 of the soup. Skip the blending if you prefer a firmer soup texture. If you don’t have an immersion blender, puree 2 cups of the soup in a regular blender or food processor; include some of the soup’s liquid to blend smoothly. Or, blend the whole thing up in a high-speed blender (in batches) to make a silky smooth lentil soup.
Lentil soup keeps in the fridge for about 5 days and freezes well in an air-tight freezer-safe container for up to 3 months.
Notes
Be very careful when blending hot mixtures. Never fill the blender/food processor more than 1/4 the way full, as hot liquids expand when blending.
If waiting longer than one hour to serve, leave the soup pot on the stove but turn the burner to the lowest setting. You can leave it on the stove for 2-4 hours. If it gets too thick, just add another 1-2 cups of water. This recipe is really that flexible.
