This one-pot healthy lentil soup recipe is so delicious, it’s sure to become a staple in your home!
Voted The #1 Best Lentil Soup
This classic recipe is ultra thick, hearty, and made with just nine ingredients!
While you can find thousands of recipes for how to make lentil soup from scratch, this is the hands-down winner of anything I’ve ever tried, and it’s thanks to a secret cooking trick that makes all the difference.
If you want a lentil soup that will quickly become a family favorite, I highly recommend giving it a try. The original recipe was my grandmother’s, and it actually won first prize when she entered it at a country fair!
The soup has been on regular rotation in my family for years, and I’ve adapted the original version to make it my own.
If you’re browsing online trying to decide which lentil soup recipe to make, this one will not let you down.

The recipe is so delicious and easy to make, you will never go back to canned soup again.
One of my favorite parts about this soup is that it freezes well, so you can portion it out and freeze the leftovers for a rainy day. It’s full of nutrition, protein, fiber, and so much flavor, and it is pure healthy comfort food in a bowl!

The Easy Lentil Soup Recipe
Trick #1: Pulverize the base ingredients <— This trick makes all the difference!
So many lentil soup recipes skip this step, which is a huge mistake! Blending the base ingredients not only lets you thicken the soup without adding flour or cornstarch, it also adds so much depth of flavor. The trick is to pulverize before adding the lentils so you get all the benefits of the extra flavor without having to sacrifice texture.
Trick #2: Keep it simple.
While ingredients such as kale, sweet potato, cumin, paprika, garlic, spinach, or lemon zest all might make nice additions, this classic lentil soup is so good on its own that there’s honestly no need for extra add-ins or spices. By keeping it simple, you allow the main ingredients to really shine.
Trick #3: Cook until carrots are soft.
You’ll often see carrots as an ingredient in soup recipes, and for good reason. As long as you add them at the right time, their natural sweetness will transfer to the broth while cooking and balance the flavor of the soup.
This particular recipe calls for the carrots to be added in the middle of the cooking process, ensuring they’re perfectly soft without being overcooked.
While you can definitely serve the soup the day it’s made, the taste is even better if you wait 24 hours, because doing so gives the individual flavors a chance to come together and intensify. There’s actually a long scientific explanation for why leftovers always seem to taste better the next day; it’s not just in your head!
Serving Suggestions: Banana Muffins or Keto Muffins
The soup is especially good with homemade English muffins from the Hello Breakfast Cookbook.
Can I Double The Recipe?
The recipe as written yields about five cups, and it can easily be doubled to feed a larger family or if you want enough leftovers to freeze. The soup is also great for meal prep.
Do You Have To Soak The Lentils First?
Nope! Unlike other dried legumes or beans, lentils can safely be cooked without soaking. (Split peas and mung beans also do not require soaking.)
If you have time, soaking dried lentils overnight increases digestibility and reduces cooking time, but it’s also perfectly fine to either skip the soaking or make this lentil soup using canned lentils.
Should I Use Green Or Brown Lentils?
It’s your choice, as both work well.
I haven’t tried red lentils here, but many readers have commented that they’ve successfully made this soup with red lentils.
Can I Make It In A Slow Cooker?
You can! Follow the same instructions as if cooking it on the stovetop, skipping the simmering step and instead cooking in a crock pot on low 6-8 hours or high 3-4 hours, or until carrots and barley are tender.
What About Instant Pot Lentil Soup?
Sauté the onion in oil if desired, using the sauté function, then pulverize with the celery, tomatoes, and broth. Add all remaining ingredients, lock, and set to high pressure for 2 minutes. Once done, cancel and carefully do a quick release.
The recipe can be vegetarian and vegan, low calorie, gluten free, soy free, dairy free, low fat, oil free, and it’s so rich and thick that it’s almost more like lentil stew than soup.
Hopefully you will love it as much as we do!

Lentil Soup – The BEST Recipe!
Ingredients
- 1/2 a large onion, diced
- 1 1/2 tbsp oil (can be omitted for fat free)
- 1/4 cup chopped celery
- 14 oz chopped tomatoes
- 14 oz vegetable broth
- 1 1/2 cups cooked or canned lentils
- 1/4 cup chopped carrots
- 1/4 cup uncooked pearl barley or rice
- 1 tsp salt
- 1/2 tsp dried rosemary
- optional pepper to taste
Instructions
To make the soup: either sauté onion in oil or just combine it with the celery, tomatoes, and broth. Bring to a boil over medium-high heat. Pulverize. Then add all remaining ingredients, lower to a simmer, and cover. Simmer 25 minutes or until carrots and barley are tender. Taste, and add additional seasonings if desired. If you try the recipe, don’t forget to leave a comment or rate it below!
*Notes: I usually add the oil for its rich flavor, but especially if you’re used to low-fat soups, this one is still good without it. The 1/4 cup barley adds thickness to the soup by soaking up some of the liquid during cooking. If using dried lentils, cook them before starting the soup. (If using canned lentils, drain and rinse first.) Canned diced tomatoes are fine; you just might want to cut back on the salt in the recipe if using tomatoes with salt.

10th January 2019 at 9:08 amHello Katie, this soup sounds wonderful! You referenced homemade English muffins from your Hello Breakfast cookbook in your post. I bought that cookbook but can’t seem to find the recipe for them. Help, I would like to make them with the soup!

10th January 2019 at 10:30 amThis sounds great and I think I have all of the ingredients already- I love when that happens! 🙂 When you ‘pulverize’ do you use an immersion blender or some sort of masher? Thanks!
Jason Sanford says
10th January 2019 at 10:49 amImmersion blender, but you could also use a blender if you don’t have a stick blender 🙂

Sandra says
11th January 2019 at 9:45 amSo funny, my grandmother also entered a soup recipe into a fair and won a prize. Who brings soup to a fair?! It seems to random but I guess it was a thing back then? It’s also still a soup we make today. Lol but her recipe wasn’t vegetarian at all!

11th January 2019 at 9:30 pmJust made this for dinner and it turned out great! I used red tllentils and fine barley. I added dried lentils and allowed them to cook with the recipe (added more liquid to make up for it). Keeper 🙂
Kate says
12th January 2019 at 6:49 amI made this lentil soup with red lentils and brown rice last night for dinner. I agree with the comment above mine. It’s a keeper!
Sue says
12th January 2019 at 7:59 pmJust made this for dinner tonight and it’s simple and a keeper. I thought only 1/2 tsp of seasoning would be too small an amount but it was perfect – adds just enough flavour without overwhelming. I used yellow lentils and brown rice. I paired it with homemade cornbread, yummy. Definitely going in our rotation, hearty enough to meet my husband’s approval 😉
Jason Sanford says
13th January 2019 at 4:03 amThanks for reporting back for the rest of us that it works with yellow lentils too! -Jason
Michelle says
13th January 2019 at 3:52 pmI made this soup today, double recipe and it’s amazing!!! I doubled the recipe and added more carrots and a little more barley than called for but absolutely amazing!! I didn’t add rosemary and honestly it’s one of the better soups I’ve made in awhile.
How many calories would you predict are in this per serving? I did use olive oil, but I used low sodium veggie broth to cut down on salt! Thanks for sharing

15th January 2019 at 10:01 amJust made this adding some black pepper and lemon juice to taste. Yummy! I couldn’t find my barley (either that or I ate it all and forgot) so I gave quinoa and really liked the texture it gave. So simple too! Thanks for the recipe.
Jason Sanford says
15th January 2019 at 3:07 pmI need to try it with quinoa now!

16th January 2019 at 7:32 pmI love lentil soup! Lately I’ve been eating lentils every single day. Definitely have to make more exciting recipes with them such as curry, sloppy lentil joe’s, and this soup for sure!
Rachel says
19th January 2019 at 6:15 pmI’m making this right now for the 2nd time in 3 days. It is so simple and SO delicious! Blending the base is a game-changer. It has a wonderfully comforting, nostalgic flavor like tomato soup or-dare I say-Spaghetti O’s. But like a grown-up, refined version of Spaghetti-O’s.

22nd February 2019 at 2:59 pmI’ve been looking for a simple lentil soup recipe all winter. When I saw this in one of my emails, I knew it was the one to try. It was exactly what I’d been looking for! I just made it today, and it did not disappoint! It was sooooo good! However, transferring boiling liquid and veggies to my blender was quite a pain, and every time I turned on the blender, despite holding down the top, it kind of exploded out the top making a big mess with very hot liquid! So you think I could liquify before boiling? Thanks!

Lisa says
26th March 2019 at 7:25 pmYou’re right – this is THE best lentil soup recipe! I’ve made lentil soup before and it’s been a chore to eat. This was literally so good I can’t keep it around my house because it gets eaten so fast. The barley is so perfect for texture and pulverizing the first few ingredients is a game changer. Love it!!!!
Sandi VanKnowe says
2nd April 2019 at 11:35 amI used dried red lentils, which look light yellow after cooking. And I doubled toe recipe. There were 6 at dinner and everyone seemed to like the lentil soup!

16th April 2019 at 1:48 pmmaking lentil soup for Lent…how appropiate
Kaylyn says
17th April 2019 at 8:58 pmThe recipe came out really well both times I’ve made it. The first time I pre-cooked the red lentils and the seond time I just tossed in 1/2 cup of dried red lentils at the same time I added in the barley and they came out much firmer. So with red lentils that are precooked it’s a smoother soup and for anyone who likes chunkier soup it may be better to out them in dry at same time as barley

31st May 2019 at 9:10 pmIt is so good, it is ridiculous. I added a bit more barley beacaue I love it so much and a tad less lentils. It is like a souped up tomatoe soup, no pun intended
