Let’s Make This Lentil And Sweet Potato Soup!

It is always best to make sure you have everything ready to go. I use a process called mise en place, or everything in place and ready to go.

Start sauteing your onions. A lot of people like to skip this step when making soups or other hot foods, but I don’t recommend it. It takes a lot of the “bite” out of the onions if you saute them. I love shopping for cookware at Marshall’s and most of my pans are stainless steel. I have never bought a set, I prefer to choose what pans I need and purchase them for a discounted price at Marshall’s.

Add in your sweet potatoes and garlic. Saute this for only a minute or 2. Garlic likes to burn, so keep an eye on it.

Now, add in your lentils, stock, spices, etc. Give it a good mix.

Once the lentils are tender, then pour in your coconut milk and kale. Cook for several minutes until the kale is wilted and the soup is blended.

  • 2 tablespoons olive oil
  • 2/3-3/4 cup minced onions
  • 4 cups sweet potatoes peeled and cut into 1-2 inch pieces
  • 2 tablespoons garlic
  • 1 tablespoon fresh grated ginger If you don't have the fresh, you can always use 1 teaspoon powdered.
  • 1 pound lentils
  • 6 cups vegetable stock or water
  • 1 tablespoons yellow curry powder
  • 1 teaspoon cayenne pepper if you prefer a little less spice, reduce this to about 1/2 teaspoon
  • 2 teaspoons salt you can taste and adjust the seasoning after it has cooked
  • 2 cups chopped kale
  • 3/4 cup cilantro plus more for garnish
  • 1 15 ounce can coconut milk


  • Heat medium-size stock pot over medium heat. Once it is heated, add olive oil. Then add in your onions. Allow them to saute for about 3 minutes. Once they are cooked, add in your garlic, ginger, and sweet potatoes. Let these cook for only about 1-2 minutes. Next, add in your lentils, stock, curry powder, cayenne, kale, and salt. Cover and reduce heat to low. This will need to cook for at least 15-25 minutes. Check occasionally to stir and check for tenderness of the potatoes and lentils. Once it is cooked, pour in the can of milk and cilantro. You can reserve a little of the cilantro to use for garnish.
    This soup is really delicious the day of, but it is also really good as meal prep. It will hold well in the fridge for up to 5 days. Just remember to cover tightly!
    Now, sit back and enjoy. You deserve it!

    Made the recipe and on review, I noticed I hadn’t added the ginger. Its listed in the ingredients short list, but not the actual recipe. Also, I assume a whole can of coconut milk? Pretty tasty without the ginger but I may add a bit of ginger powder at this point.

      Yes, there is ginger. Let me change that! It is the whole can of coconut milk. We love this soup so much, I am glad you like it too!
