This Sweet Potato & Lentil soup is cozy, hearty, and made with only 8 healthy ingredients!
A perfect cold-weather lunch or dinner.

It’s been cloudy and rainy here – a.k.a typical Pacific Northwest weather in the Fall. While some people dread the change of seasons, I love it! It makes for the perfect excuse to take out my giant pot and whip up a batch of nourishing and cozy soup. Not only is this Sweet Potato & Lentil soup made with only 8 ingredients, but it’s also budget-friendly and freezer-friendly too.

Shall we?

Like most great soups, this one starts with an aromatic base of garlic and onion. We’ll sauté those in a splash of neutral oil or vegetable broth until translucent, then add in some fresh rosemary and thyme for the *ultimate* Fall-infused-flavor situation. 

In go the lentils, cubed sweet potato, and vegetable broth – and that’s pretty much it! Bring the soup to a boil, then simmer until the lentils are tender. Stir in some fresh baby spinach just before serving, then top with freshly ground black pepper for a little kick.

This Sweet Potato & Lentil soup is perfect for meal prep and makes the perfect cold-weather lunch or dinner. One of my favorite things is to create BIG flavor recipes made from minimal ingredients, and this one does just that.

If you’re serving a crowd I’d recommend bulking this soup up with a side of crusty bread, or a side of my Everyday Kale Salad. Or both, go crazy 😉

A Few Final Thoughts:

  • I used dried brown lentils for this recipe – I love how they absorb the soup flavors as they simmer away, providing an extra burst of flavor. If you’re in a time crunch, though, you can always use canned lentils – just reduce the vegetable broth by 2 cups and simmer until the sweet potatoes are tender.
  • Feel free to add in some of your other favorite fall veggies here! Carrot, celery, tomatoes, and even broccoli would be great here. You can also swap the baby spinach for kale or collard greens.
  • If you’re looking for more cozy soup recipes, you’ll also love this Curried Lentil Soup, this Green Pea Soup, and this Smoky Black-Eyed-Pea Soup with Quinoa!

    1. We haven’t made the recipe with the green ones; green lentils take longer to cook and will hold their shape far better than brown lentils. If you can get brown we’d recommend them! If you use green keep in mind they will take more cooking.

  1. I just made this and oh my goodness! very delicious, I didn’t have any rosemary so it’s the only ingredients I lacked but it’s still so flavorful.. definitely be cooking this next time.. Thank you for the recipe Caitlin! 🙂 <3

    1. Red lentils won’t hold their shape very well and will likely become pretty mushy if you do decide to use them. Definitely recommend the brown lentils!

  2. Was so good, my hubs requested I make a second batch the same day, so I did! I’d say that’s a win! Made in the IP. Thank you!

  3. I made this and it was AMAZING. SO GOOD. I’ve been eating it this past week every night for dinner and it has not failed to hit the spot.

  4. followed the recipe & added carrots, celery, and some diced tomatoes.
    SO GOOD!!!! all my roommates (even picky ones) love it.

  5. I made literally every recipe from this video and have never been more pleasantly surprised! This soup came out awesome, tons of flavor and so so easy to make. Thank you for these simple recipes!

    1. Yes, I don’t see why not! I would use the sauté setting initially, then pressure cook on high for 15 minutes

    1. You COULD use just water (same amount, 6 cups) but the broth is what helps give it so much flavor!

  6. Wow! This soup is perfect for autumn! Vegan, healthy and natural..What can be better? Thank you for this amazing recipe!
