These roasted potatoes are a perfect side for steak or prime rib, or else simply served as a shared starter. I love the flavor paring of the creamy and crispy potatoes and the horseradish and chive sour cream. The Anova Precision Oven makes it easy to achieve perfect potatoes every time because of its ability to both steam and brown with the same cooking device. Note: This recipe works best when there’s some airflow underneath the potatoes. The photos in this recipe show a perforated pan, which is now available to order through Anova. If you don't have one, placing a wire rack over a sheet pan works as a substitute.
