For the creamiest texture, keep the heat low after adding the cream and Parmesan and avoid boiling the soup, which can cause separation. If you prefer a thicker keto chicken soup, let it simmer uncovered a bit longer after adding the vegetables, or stir in an extra handful of riced cauliflower and cook until it softens and naturally thickens the broth. This soup stores well in the refrigerator for up to three days; reheat gently over low heat and add a splash of bone broth or cream if it thickens too much. To keep the soup fully keto and gluten free, be sure to use unsweetened bone broth and avoid any broth brands that contain added starches or sugars.
