What You Need for This Recipe

The beauty of this soup lies in its simplicity. A handful of ingredients come together to create something incredibly flavorful.

  • Sweet Potatoes – These add natural sweetness and a creamy texture when cooked down. They also bring essential vitamins and a boost of fiber.
  • Kale – A hearty green that holds up well in soups. It softens just enough in the broth while still adding a bit of texture.
  • Vegetable or Chicken Broth – Forms the base of the soup, adding depth and richness. Use homemade broth for an even deeper flavor.
  • Aromatics – Onion, garlic, and a touch of thyme build layers of flavor in the broth. These small additions make a big difference.
  • Protein (Optional) – Chickpeas, white beans, or shredded chicken can make this soup even more filling. It’s easy to adjust based on your preference.
