How to make sweet potato kale soup

This sweet potato kale soup combines ingredients we use quite a bit in our cooking in a new way. It’s a vaguely Mexican stew, with black beans thrown in and flavored with oregano, cumin, and just enough lime juice so that it pops. Sliced green onions stirred in at the end of cooking keep it tasting fresh, and with sliced radish and a dollop of Greek yogurt as a garnish, it’s a delicious way to load up on nutrients. (Want more ideas? Here are some of our favorite soup recipes.)

This sweet potato kale soup features black beans and is flavored with cumin and lime; it’s a hearty gluten-free and vegan soup recipe.


  • 1 large yellow onion
  • 4 medium garlic cloves
  • 1 15-ounce can SimplyNature Organic Black Beans
  • 2 tablespoons olive oil
  • 2 teaspoons dried oregano
  • 1 1/2 teaspoons cumin
  • 1 teaspoon garlic powder
  • 1/2 teaspoon black pepper
  • 1/8 to 1/4 teaspoon cayenne (optional)
  • 1/2 teaspoon kosher or sea salt
  • 1 pound sweet potatoes (3 cups cubed)
  • 1 quart (4 cups) SimplyNature Organic Vegetable Broth
  • 4 cups chopped SimplyNature Organic Kale (about 3 ounces)
  • 3 green onions
  • 2 radishes, thinly sliced
  • 1 tablespoon lime juice
  • 6 tablespoons Friendly Farms plain Greek yogurt, as a garnish (optional)
  • Hot sauce (optional)


  1. Dice the onion. Mince the garlic. Dice the sweet potato. Drain and rinse the beans.
  2. In a large pot or Dutch oven, heat the olive oil over medium high heat. Add the onions and sauté 4 minutes, until translucent. Reduce the heat to medium, add the garlic, oregano, cumin, garlic powder, black pepper, and cayenne (optional), and sauté for 30 seconds. Stir in the sweet potatoes, then add the vegetable broth, beans, and kosher sea salt and bring to a simmer.
  3. Once boiling, reduce to a simmer and simmer 15 minutes until the sweet potato is tender. While simmering, roughly chop the kale. Thinly slice the green onions and radishes.
  4. When the sweet potatoes are tender, remove from the heat and stir in the kale, green onions, and lime juice. Allow to cool slightly before serving. Taste, and if desired add additional kosher sea salt to taste. Serve garnished with radishes, a small dollop of Greek yogurt (optional), and hot sauce.

    Beautiful soup. It took us a while to have the lightbulb moment of Greek yogurt instead of sour cream, but now that we are there, we all love it. It is suprisingly similar to sour cream, and gives just the right amount of tart creaminess to tacos, burritos, chili, soup… The list is endless and the no guilt makes it very, very satisfying. We always have a large container on hand, and it’s usually from Aldi.

      Ooo thank you! Yes, we love Greek yogurt on all the Mexican foods — along with a little Mexican hot sauce, right?!

    Looks delish! bonus…!’m pretty sure i have all the ingredients on hand. I think it will be nice topped with some avocado as well. My Aldi usually has organic ones handy.
    Thanks for a new twist on kale and potato soup!

    Any recommendations for making it in a slow cooker instead? Thanks!

      Hmm, we haven’t tried this in a slow cooker (we actually don’t use ours too often, haha!). Since it simmers pretty quickly, if you’re looking to save time, I’d chop the ingredients in advance. It should come together in about 20 minutes if everything is already prepped!

    So delicious! Thank you! I substituted oregano for cilantro and really enjoyed it as a garnish for the soup.

      Great idea to use oregano instead of cilantro! It still “fits” in the vibe — so glad you had that idea!

    Making this again for the fam (and just rated it, too)! I love it, the hubs loves it, and our toddler can’t get enough! Having to modify (again!), cause I don’t have radishes, green onion, or yogurt. But such is life when you decide to whip it up last-minute. Even modified, it’s still yum-o! Thanks for the inspiration, y’all!

      Oh we’re SO glad to hear this, and thanks for the rating! Don’t worry about the modifications — a recipe is just a template anyway, right?! So glad to hear that your toddler loves it too — that is the best compliment!

    It is redundant to say that something is vegetarian and vegan. Anything that is vegan is, by definition, vegetarian.

    This has become one of my most used recipes. Substitute spinach for kale, or cannellini beans for black beans,, add chicken, So versatile.

    I made this soup for lunch today, and it was delicious! I didn’t have any radishes, but followed the recipe otherwise. I will definitely make this one again!

    Thank you for this recipe. I didn’t have vegetable broth so I used bone broth with lemongrass and jalapeño. It was sooo good!
