  • This keto kale soup is a version of our number one most popular recipe-- Tuscan Sausage and White Bean Soup and it's keto-friendly version, Low Carb Tuscan Soup.
  • People have different preferences on the texture of cooked kale. If you like yours with a bite, only sauté it for a few minutes. On the flip side, if you like a very wilted, soft kale texture, keep sautéing until it darkens in color and shrinks down.
  • To make this a low carb soup, we eliminated the flour,  swapped the evaporated milk for heavy whipping cream, replaced the beans with riced cauliflower.
  • Not familiar with riced cauliflower? You can find this in the freezer section of the grocery store. We use the steamer bags that you cook in the microwave.
  • To give this keto creamy kale soup even more flavor, don't drain the grease off the sausage after you cook it. Or, drain it and add a little back when you add the sausage.  The pork sausage grease has amazing depth of flavor.
  • For a thicker broth, remove a cup or two of the soup, puree and add it back as a thickener.
