This creamy potato and hamburger soup is a comforting, one-pot meal perfect for chilly evenings, made easily in a slow cooker.
For a lighter version, use 90% lean beef or ground turkey. For a dairy-free option, substitute milk with unsweetened oat or almond milk and use plant-based cheese and dairy-free sour cream. For thicker soup, replace part of the milk with half-and-half.
