Summer is oh so slowly fading awayโฆ Which means itโs time to start whipping out all of the best soup recipes! Cozy up with something warm, delicious, and vegan this fall and winter. Some of the best soup recipes include (but are certainly not limited to) Broccoli Cheddar Soup, Spicy Peanut Soup, and Instant Pot Tomato Soup!
The very best lentil soup
When it comes to Lentil Soups, they donโt get much more satisfying than this one! Itโs a bare bones soup, meaning you wonโt find any unnecessary frills or complicated steps here. Itโs a classic recipe thatโs the definition of tried and true!
With that being said, itโs also anything but bland. The medley of mouthwatering spices and mix of fresh veggies keep this thick Lentil Soup plenty flavorful. Oh, and that squeeze of fresh lemon juice right at the end is like the cherry on top!
What makes it the best?
- The ingredients are inexpensive! In fact, you likely already have the majority of these ingredients in your kitchen now. If you donโt, this recipe is a great excuse to start stockpiling all of your inexpensive cooking essentials!
- Itโs so filling. The amount of protein-packed lentils and nutritious fresh veggies in this thick soup make it wonderfully filling! Trust me, this Lentil Soup always hits the spot and satisfies everyone around the table.
- The flavor is truly delicious! Smoked paprika, coriander, cumin, and just a touch of salt create a flavorful medley of spices that make this soup downright delicious. And since youโre making this soup at home, you can alter the spices however you see fit!
Ingredients needed (with substitutions)
- Olive Oil – Avocado oil can be used instead.
- Onion – Feel free to use a white or yellow onion, either one will work well.
- Garlic – Fresh garlic will yield the best flavor here.
- Carrots – When you chop them up, make sure theyโre in small enough pieces to fit onto your spoon with the other ingredients.
- Celery – Rinse your celery with water and pat it dry before chopping. That way, thereโs no dirt or residue still on it.
- Tomatoes – Use a can of either crushed or diced tomatoes. Either one will get the job done.
- Lentils – You can use green or brown lentils – whichever you prefer!
- Vegetable Broth – Use a low sodium vegetable broth for a less salty taste.
- Spices – Youโll need a medley of ground cumin, ground coriander, smoked paprika, and just a light sprinkle of salt to make this Lentil Soup supremely flavorful!
- Baby Spinach – Slice your spinach into ribbons so itโs easier to eat in your spoonfuls. Also, you can substitute this for kale if youโd like.
- Lemon – Make sure youโre using freshly squeezed lemon juice only – nothing from concentrate!
How to make lentil soup
Find the complete printable recipe with measurements below in the recipe card.
Heat the olive oil in a large pot over medium heat. Add the onions, garlic, carrots and celery. Cook, stirring frequently for about 4-5 minutes.
Now add the can of tomatoes (with juices), lentils, vegetable broth, cumin, coriander and smoked paprika. Stir to incorporate everything.
Bring to a boil, then lower heat to a simmer and cook for about 30 minutes, until the lentils are tender and the soup has thickened. If desired, use an immersion blender to slightly blend and thicken it.
Stir in the spinach and lemon juice. It will only take a minute for the spinach to wilt. Season with salt to taste.
Frequently asked questions
- Can I change the consistency of Lentil Soup? Yep! For a thinner soup, simply add more water or vegetable broth until the desired consistency is reached. You can also blend it just a few times with an immersion blender for a slightly creamier soup.
- Can I freeze Lentil Soup? You sure can – and it freezes so well! In a freezer safe food storage container, your leftover Lentil Soup will stay fresh for up to 3 months. You can keep it in one large container or several small containers for individual portions.
- Can I swap the spinach for kale? Yes, just make sure that you cook the kale for about 10 minutes longer than you would the spinach so itโs nice and tender.
What to serve lentil soup with
I like to serve this hearty soup with some Dutch Oven Bread and perhaps a Vegan Caesar Salad.

Notes
- For a thinner soup, simply add more water or vegetable broth until the desired consistency is reached.ย
- Leftover soup will keep for up to 5 days in the refrigerator.
- This soup freezes well. Either freeze in individual containers or a large container for quick future meals.
- May substitute kale for the spinach, but you will need to cook the kale in the soup about 10 more minutes to get it tender.ย
This is a go-to recipe for me, delicious flavour and straightforward to make. I use half the amount of puy lentils.

I’ve made this once before and it was so delicious! I’m wondering if I could cook it in the crockpot as well?
Yes, that works well. Simply place everything in your crock pot and cook either on high for 4 hours or low for 8 hours. Thanks!

Hi,ย
My family and I absolutely love this lentil soup recipe!
Iโm wondering if you have a rough estimate of how much 1 serving is equivalent to (in cups)?
Thank you!ย
Hi Meghan. I’m so glad you guys love the soup! Thanks so much for sharing your wonderful review! There are 8 servings total, so about 1 1/2 cups of soup.
Just made this dish. I couldn’t agree more with it being “The best lentil soup”. The texture and the flavours worked so well and it tastes super delicious and also so easy to make. Thankyou
Hi Jennifer! I’m glad you loved the lentil soup! Thanks so much for taking time to share your great review and comments!
Tasty! I also made my own veggie broth.
Thanks for sharing your great review!
Delicious!
I made this before and it’s fabulous. I’d like to make it for a friend who can’t do tomatoes – any suggestion for a substitution?
I would just leave them out, I think it will still be great!
Made this for dinner today. ย Iโve never really eaten lentils before. Iโm not Vegan or Vegetarian, but Iโm currently in the midst of a lifestyle change and Iโm trying new things as often as possible. This soup was delicious. I made it exactly as is, without any changes or substitutions, and I can honestly say I will be making it regularly now. ย It was simple to make, inexpensive, and tasted wonderful. Thank you so much for a healthy new recipe!ย
Hi Amber! I’m so thrilled that you love the soup and will be making if often! Thanks for taking your time to share your wonderful review! Happy cooking!
Can I use canned/steamed lentils and just throw them in near the end?ย
You probably could but I would use a bit less broth.
Can I use black lentils? ย
Sure, that’s fine!
During the pandemic I was able to take time and try many different vegetarian lentil soup recipes. This is my favorite by far! The spinach and lemon are perfect additions. Thanks so much! Going to buy your book in my local independent book store.
Thank you so much, I’m glad you love the soup as much as I do! Unfortunately, I don’t have a hardcover cookbook yet. But I hope to one day!
we’re a soup family and this is REALLY GOOD SOUP! Perfect on this dreary, cool day. I didn’t have celery so I added extra carrots & mushrooms in the beginning. Ended up adding a touch of sugar and some tumeric (trying to get my husband to have more in his diet). Once it started boiling, I added some cauliflower pieces (it was going to go bad if I didn’t use it). So good and filling. Ate it at lunch and haven’t even thought about dinner yet.
I’m really glad you guys loved the soup! Thank you for taking your time to share your review and comments!
So yummy!! my partner and I loved it ..going away for weekend and have just made up another lot..
Glad you guys loved the soup! Thanks for sharing your review! Enjoy your weekend!
ย I was searching for soups to make with lentils that have been soaking overnight.ย
**Lentils can be tricky, I often read only a rinse is necessary but then soaking for 4 hours – overnight is best.
Am I able to use soaked lentils (theyโre green) in this recipe?ย
I’ve never tried it, but I don’t see why you couldn’t use soaked lentils.
Amazing, all the kids loved it and all bowls emptied. Every single one of your recipes has been really really nice. My favourite recipe website by far!
I added some butternut squash blended in with the sauce to sneak in some extra veg as they wont have the spinach! Thank you for another delicious recipe.
Hi Laura. I am so thrilled you are loving my recipes! Thank you for taking your time to share your great review!
I absolutely love this soup. I made it for about 14 friends last week who raved about it and asked for it again this week! I obviously have to triple the ingredients. I also grate my carrots instead of chopping them. Thanks for a great recipe.
I’m so glad to read you and your friends are loving the soup! Thanks for taking time to share your wonderful comments!
This recipe is going in my favorites and Iโm very critical when it comes to a good lentil recipe. A new fave in my house. The flavors were spot on. The only thing I changed was adding a bay leaf and some pink salt into the ย soup while it was simmering. I also took about 3-4 cups of the soup and blended it up in my Vitamix then poured it back in.ย
Perfect soup for a rainy day.ย
Thank you!ย
I’m thrilled you love the soup, Laura, and that it’s a new fave! Great idea to blend part of the soup! Thanks for sharing your wonderful review!
Amazing , added jalapeรฑos , bay leafs , fresh coriander and heavier on the spicesย
Thanks for sharing your great review and comments! I’m glad you love the soup!
