With its velvety consistency, this Instant Pot soup tastes way richer than it really is. Yukon Gold potato adds creamy texture and a slightly buttery note, while cauliflower helps to thicken the soup. From there, reduced-fat milk brings it into silky bisque territory. If you don’t have an immersion blender, just use a standard blender and purée in batches.
