For the smoothest texture, make sure the cream cheese is softened to room temperature and add it gradually while whisking over gentle heat. If the soup ever seems too thick, whisk in a splash more chicken broth or a bit of water until it reaches your desired consistency. Leftovers keep well in the refrigerator for up to 4 days and can be reheated gently over low to medium low heat, stirring often to maintain creaminess and avoiding a hard boil. To keep carbs in check, serve this soup alongside simple low carb sides like a leafy green salad or sautéed non starchy vegetables instead of bread or crackers.
