The Irresistible Trifecta of starchy, creamy, and comforting pleasures found in loaded potato soup makes this warming bowl a restaurant and home-cooked favorite, especially on chilly, wintry days. The challenge with lightening is obtaining that luscious, creamy texture without any cream. Potatoes are a tricky starch. Cauliflower, however, has a smooth flavor and a skinnier, less starchy profile. When roasted, it develops a creamy interior (and nutty flavor) that becomes delightfully smooth when blended with reduced-fat milk; this is the light, earthy base for our chunky potato soup.
