Flavorful Lentil Soup
I’ve never liked any lentil soup recipe enough to share until now. After making and eating (hello comfort food!) a lot of batches this week while feeling a bit sick, I’ve finally got a perfect Lentil Soup recipe.
I used up all the leftover veggies from my fridge, so if you need to clear out yours, this is the meal for you. It’s packed with carrots, onion, celery, garlic, tomatoes, potatoes, and sweet potatoes—it’s like a healthful vegetable soup with lentils!
The lentils make this soup really filling and high in protein. With just the right spices and a splash of lemon, it’s totally delicious.
Ingredients In Lentil Soup
- Olive oil: Makes the vegetables soft and adds flavor.
- Onion, carrots, celery: These are the basic veggies that make the soup taste really good.
- Garlic: Adds a strong and yummy taste.
- Potatoes & sweet potatoes: Make the soup thicker and filling.
- Lentils: Add protein and make the soup even thicker.
- Tomato paste and spices: Make the soup taste spicy and rich.
- Bay leaves: Give a special flavor that’s subtle but nice.
- Lemon juice & zest: Make the soup taste fresh and zingy.
- Parsley: Adds a fresh green taste.
- Vegetable broth & chicken stock: They are the liquid that everything cooks in, making it actually a soup.
- Diced & crushed tomatoes: Add a tomatoey flavor and chunks for a nice texture.
How To Make Lentil Soup From Scratch
- Chop your veggies.
- Cook onions, carrots, and celery in a pot. Add garlic and potatoes after a few minutes.
- Stir in tomato paste and spices for extra flavor.
- Add tomatoes and cook for a few more minutes.
- Pour in lentils and broth, then let the soup simmer for about 25-30 minutes until everything is soft.
- Add parsley and lemon to the soup.
- Serve hot with Parmesan cheese and bread on the side.
Tips For Success
- Vary the vegetables: Use any veggies you have on hand.
- Adjust texture: For a smoother soup, blend 2 cups and mix it back in.
- Control thickness: Add more broth or stock if you prefer a thinner soup.
- Skim off froth: Take off the foam that forms on top to make lentils easier to digest.
- Layer flavors: Spend time cooking the aromatics and spices for better taste.
- Use fresh ingredients: Don’t skip parsley, lemon zest, or juice for the best flavor.
- Cut veggies evenly: Dice everything small and uniformly for consistent cooking.
Storage
How To Store Leftovers
- To refrigerate: Allow the soup to cool to room temperature. Transfer to an airtight container and refrigerate. Lentil soup will keep for 4-5 days when properly stored. This soup makes a great weekly meal prep!
- To freeze: Allow soup to cool to room temperature. Transfer to an airtight, freezer-safe container (leaving about an inch of room for expansion). Freeze up to 3 months. Thaw straight from the freezer on the stovetop (reheat gently) or in the microwave. You may want to add an extra splash or two of broth as it will be thicker upon thawing.
Lentil Soup FAQs
What Type Of Lentils Are Best For Lentil Soup?
Use dried brown or green lentils; they cook in 20-30 minutes, thicken the soup, and add mild flavor. Red lentils get mushy and change the texture, while Puy lentils take too long to cook and may overcook the veggies.
Can I Use Canned Lentils?
I recommend dried lentils for better flavor, texture, and cost. If using canned, add one drained and rinsed can after 15 minutes of simmering, then cook for 10-15 more minutes until tender.
Do Lentils Need To Be Soaked?
No! Lentils do not need to be soaked before using in this soup. For this recipe, I rinse them off and then they cook in the soup.

Lentil Soup
Lentil Soup is hearty, veggie-packed, and ultra comforting—a filling bowl of goodness perfect for any day.
Equipment
- Large cast-iron pot or Dutch oven
- Blender optional
Ingredients
- 1/4 cup olive oil
- 1 cup diced yellow onion 1 small onion
- 1 cup diced carrots 2 medium carrots
- 1/2 cup diced celery 1 to 2 stalks
- 1 heaping tablespoon minced garlic 4 cloves
- 1 cup diced Yukon gold potatoes
- 1 cup diced sweet potatoes
- 3 tablespoons tomato paste
- 2 teaspoons ground cumin
- 2 teaspoons Italian seasoning
- 1 teaspoon yellow curry powder
- 1 teaspoon salt
- 1/2 teaspoon ground turmeric
- 1/2 teaspoon ground paprika
- 1/2 teaspoon pepper
- 1 (14.5-ounce) can fire roasted diced tomatoes
- 1 (14.5-ounce) can fire roasted crushed tomatoes or an extra can of diced
- 3/4 cup lentils brown or green, rinsed in cold water
- 1 (32-ounce) container vegetable broth
- 1-1/2 cups chicken stock or additional vegetable broth
- 2 bay leaves
- 1 lemon
- 1/3 cup finely chopped freshly flat leaf parsley
- Hearty buttered bread for serving
- Parmesan cheese for serving
Instructions
- Add the olive oil to a large, cast-iron pot or Dutch oven and heat over medium. Once shimmering, add in the diced yellow onion, diced carrots (no need to peel), and diced celery. Cook, stirring frequently, 5–7 minutes. Add in garlic, stir, and cook for 1 minute. Add diced potatoes (again, no need to peel) and diced sweet potatoes (I do peel these). Stir to coat everything in the oil and cook for 3 minutes.
- Add tomato paste and all seasonings: ground cumin, Italian seasoning, yellow curry powder, ground turmeric, paprika, and salt and pepper to taste. Stir, toasting the seasonings and coating all the veggies. Cook for 2 minutes. Add undrained fire-roasted diced tomatoes and undrained fire-roasted crushed tomatoes. Cook 2–3 more minutes, stirring frequently, to bring out all the flavors.
- Rinse the lentils in cold water in a fine mesh sieve. Add lentils, vegetable broth, and chicken stock (or additional vegetable broth) into the pot. Stir in the bay leaves.
- Increase heat and bring the soup to a boil. Once boiling, you’ll see some bubbles or froth at the top of the pot. Skim this off with a spoon and discard. Stir, then reduce heat to medium low so the soup is gently simmering. Partially cover the pot with a lid, leaving some room for steam to escape. Cook 25–30 minutes or until lentils are tender (they should still hold their shape).
- Optional (creamier texture): Transfer 2 cups of the soup to a high-powered blender. Securely fasten the lid and blend until smooth (watch out for steam!). Pour the blended soup back into the pot and stir. I occasionally do this, but also enjoy the texture of all the veggies—up to you!
- Remove the pot from heat and add 1/2 teaspoon lemon zest and 1 tablespoon lemon juice. Taste and adjust seasonings; add additional lemon juice if desired, salt and pepper if needed, and/or a pinch of red pepper flakes. Stir in the freshly chopped parsley.
- Serve while hot. Top individual bowls with freshly grated Parmesan cheese. Leftovers will keep (stored properly in an airtight container) for about 4–5 days in the fridge.

Recipe Notes
Tips:
- Thin the soup. I like this soup thick and hearty, but if you’d like it thinner, add some additional vegetable broth or stock.
- Skim the surface of the soup. When cooking lentils, a froth will rise to the top. I like to skim this off with a spoon; this makes the lentils easier to digest. The froth forms as a result of lentils releasing gas and enzymes as they cook.
- Take your time. This soup requires quite a few ingredients to sauté and toast before it can be left alone to simmer. Take your time sauteing the aromatics, toasting the spices, and sauteing the tomatoes; these steps add layers of flavor.
- Don’t forget the fresh ingredients. The freshly chopped parsley, lemon zest, and lemon juice truly make all the flavors in the soup sing; I wouldn’t recommend leaving any of these ingredients out.
- Finely dice or chop the veggies. In order for everything to cook in the right time, we want the onion, celery, and carrot finely diced. The potatoes also need to be chopped small—1/2-inch or smaller cubes. The more evenly cut the veggies are, the more evenly they’ll cook (we don’t want some mushy and some hard).

Your lentil soup recipe was delicious! I enjoyed how hardy and seasoned it tasted.
Yay! So glad you loved! Thanks Deborah! 🙂
I made your lovely soup. Great step by step recipe. Photos are lovely. Can’t wait to taste it!
Thanks so much Monica! 🙂
This soup is so flavorful! I made it a month ago and just pulled a bowl out of the freezer for lunch and it was just as delicious. I’m trying to cook healthier and my husband isn’t often a fan of meatless meals, but even he agreed this recipe is a keeper. I followed the recipe as written and used no substitutions.
I am so happy to hear this! Thanks so much Laura! 🙂
I just made this soup and it is delicious. Thank you for such well written directions. I substituted little cubes of butternut squash instead Of sweet potato. Perfect for our vegan, gf and nut free family. Thanks
Delicious! So glad you enjoyed! Thanks Mandy! 🙂
Well – we are currently eating a bowl of this delectable soup. Yummy!
Score! So happy you guys enjoyed! 🙂
Whenever I plan on dinner with hubby, stepchildren, or friends I go straight to your site, never disappoint!! I also love how detailed your recipes are and the explanation of each step!! As the soup is simmering….smells delish……Again, Thank you for sharing!!!!
I am seriously so flattered to hear this! Thanks so much Cindy! 🙂
I have quite a lot of dried lentils in the emergency food stash I put together in the spring. This recipe reminds me I need to use and replace emergency supplies rather than waiting for Armageddon!
I love that you include nutrition information. I see it serves 6 but was wondering what the serving size was.
This was so delicious!!
I couldn’t find roasted canned tomatoes anywhere , so I substituted the normal Paprika with Smoked Paprika and it gave it the Smokey flavour. I was also a bit cheeky and put some Spicy Spanish sausage mince in the soup. I fried it up with the onions. I did this for my husband, who needs it a little bit more filling.
We will definitely being making this again! Thank you
I am so happy to hear this! Those subs sound delicious! Thanks for your comment Rachael! 🙂
I have quarantine issues…How important are the “fire-roasted” part of the diced tomatoes? Would 29 ounces of just diced tomatoes work?
Yes that will work 🙂
It turned out great without the “fire roasted” tomatoes…absolutely delicious…such a great rich comforting flavor, thank you Chelsea!
So thrilled to hear that! Thanks for the review 🙂
My daughter, (who is vegan) and I made this soup together. Great way to spend Boxing Day. It is simmering as I write… We added Kale and used red lentils (that’s what I had). It looks and smells delicious. Ca’nt wait to taste it!
Truly, this lentil soup is a comfort in a bowl. Such well written recipe and the pictures are so lively and lively. Thanks
Thanks!
