1 Pot Sweet Potato Lentil Soup

1 Pot Sweet Potato Lentil Soup

1 Pot Sweet Potato Lentil Soup! Smoky, flavorful, delicious and so hearty! Lots of wonderful, plant-based protein! JUST 8 ingredients! Vegan, gluten-free and oil-free!

I just love soups with a little kick, but to really balance and turn up the flavor, I like a little sweetness! That is the reasoning behind this soup I created. It has become quite a staple in my family and is a favorite among friends. It has a deep warm and smoky flavor that is balanced out with the sweetness of sweet potatoes. It's earthy and the epitome of comfort food. It couldn't be any simpler either, just throw everything into a pot and let it cook!


I have found many lentil soups to be a little bland, but this one with all of the smoky spices I've added give such a depth of flavor that is honestly addictive. The sweet potatoes really compliment the smoky flavor as well. A vegan, gluten-free, oil-free lentil soup that is totally low-fat and guilt-free? Yes, please!

1 pot, 8 purchase ingredients (+ salt) and ready in less than an hour!

I cannot wait to hear what you think of this 1 Pot Sweet Potato Lentil Soup!

  • 1 lb bag of dry green lentils
  • 1 large red onion, finely chopped
  • 3-4 large garlic cloves or 1 tablespoon garlic powder
  • 3 medium sweet potatoes, cut into bite size chunks
  • 4 tablespoons tomato paste
  • 2-3 teaspoons chili powder (depending on your heat-o-meter, I used close to 2)
  • 1 tablespoon cumin
  • 1 tablespoon smoked paprika (don't omit!)
  • 1 tablespoon sea salt (add more to desired taste)
  • 1 teaspoon black pepper
  • Optional garnish: lemon juice and zest at the end


  1. Rinse lentils well and add them into a large pot with 8 cups of water or low-sodium veggie broth.
  2. Next, peel and chop the sweet potatoes into bite size pieces (about an inch) and add them to the pot. Finely chop the onion, mince the garlic and add them into the pot.
  3. Now add all of the seasonings, tomato paste and stir well to combine everything.
  4. Bring to a boil, stir, and turn down to to simmer and put the lid on with it slightly tilted to let some of the steam escape. Simmer for 20-30 minutes or until the lentils and potatoes are tender, but not mushy, stirring a few times during the cooking process. If you cook it too fast, the lentils will not become tender. Add any more salt to taste and garnish with a splash of lemon juice and lemon zest.

    This soup is a homerun! It is super simple to make, and just bursts with flavor. It is a very hearty soup with a nice little kick to it. It's great for summer or fall amd makes enough for generous sevings for two days. Knowing it's so good for you is just an added bonus.
    • I'm so glad y'all loved it Mom! So happy family and friends love and make it during the fall and just love it! :)

  5. This reminds me of the red lentil and sweet potato soup that's on the Whole Living detox! I just LOVE the combination of lentils and sweet potato in soup, but I would probably get sick of the soup if I ate it every week...this is the perfect thing to change things up with! :)
  6. How have I NOT seen this before? I LOVE lentils and this looks amazing!!! I just used my last sweet potato tonight....grocery trip tomorrow!

      Wonderful Michelle!! Please let me know how it turns out :)

    This looks yummy. I wonder if it could be made in The Instant Pot. I might try it. However, it would kind of need to be done in the reverse order from what you have listed. The potatoes take longer to cook, so they would go in first for about 8 minutes. The onion, lentils etc. would probably only need about 3 minutes. Do you ever give recipes for pressure cookers?
    • brandi.doming@yahoo.com
      Hi! I don't own an instant pot, so I am unsure of the way it would need to be cooked. This one is super easy as you just throw everything in at the same time and in about 30 minutes, it's ready and perfect. If you do it in the instant pot, let me know how it turns out, sorry, I just don't know since I don't have one!
  8. Hi Brandi, this lentils recipe is so delicious! Made them today and my partner and I had them for dinner...........well we loved them so much. They turned out delicious, and the chilli powder it's definitely a win win. I've made lentils in the past but never got the right seasoning. Thank you very much for sharing this super easy but hearty and lovely recipe.

      Awesome Esther! I'm so happy to hear you both loved this soup so much, thank you very much for the feedback! I love it!
  9. Hi I would love to make this recipe I have a tin lentil and wonder if that can be used instead of dry lentils Jutta
    • brandi.doming@yahoo.com
      Hi Jutta! I have not tried canned lentils so I'm really not sure. The liquid that is added is to cook the lentils in, so you wouldn't need all that liquid. YOu can try canned lentils and add the spices and some extra broth if needed to make it more of a soup consistency. Those are my guesses!
  10. This soup was delicious! I'm really loving your recipes. Thank you
    • brandi.doming@yahoo.com
      I'm so happy to hear that, thank you so much for leaving feedback, I really appreciate it! So glad you are loving the recipes! :)
  11. This is excellent and the easiest dish I have made on my new whole foods plant based diet. I'm a 74-year old heart failure patient feeling very well right now. But this is such an easy recipe to prepare that I will am happy to have it in case my health and abilities deteriorate in the future. I am also sending the recipe and all the ingredients home with a visitor who is much younger but who has some serious health problems and I'm trying to encourage him into better eating habits and he'll have no excuse if I prepare a everything for him to make in the easy short time that this recipe takes. I love your recipes and thank you from all the parts of my heart which are working. :-) Carol

      Wow, thanks so much for the wonderful feedback Carol! I'm so happy to hear you loved this! This is one of my favorite recipes! Thank you for such a kind comment and for sharing the recipe!
  12. I'm having a hard time finding smoked paprika. Where do you think I should look to buy it? Am I just not shopping at the right stores?
    • brandi.doming@yahoo.com
      Oh really? Honestly, smoked paprika I've seen at every grocery store. It's in the spice isle. I imagine even Walmart would carry it. Do you have a Krogers? If so, they are usually very helpful at helping you find things. You may just be passing over it since there are so many spices in stores, but you should definitely be able to find it. It's near all the spices like cumin, chili powder, etc.
    • I can't get smoked paprika where I live (South America) but I can get smoked salt. So I use regular paprika and sub smoked salt for some of the sea salt (liquid smoke works, too). It turns out great!
  13. This soup is DELICIOUS! I made it for lunch today in my Instant Pot and it was incredible! I adjusted the water to 7 cups, and cooked it on HIGH pressure for 17 minutes, with a 15 minute NPR. So perfect! I'm making a double batch to bring to a church function tomorrow! Simple,yet satisfying, hearty soup, and packed full of flavor! Thank you!
