Sous Vide Root Vegetable White Truffle Bisque

Parsnips and rutabaga, hard root vegetables, are perfectly tender when prepared with cream and stock in the Anova Sous Vide Precision Cooker. In addition to its velvety texture, this sous vide root vegetable bisque is full of flavor — thanks in part to the addition of white truffle oil. We recommend serving it with a drizzle of good extra-virgin olive oil, or truffle oil if you really, really like truffle. Like most soups, this one is better after a night in the refrigerator and will hold for up to three days.
