Hasselback Potato Casserole

ASSEL BACK POTATOES, A dish purportedly created by Leif Elisson in 1953 at the Hasselbacken Restaurant Academy in Stockholm, are whole potatoes that are sliced thin almost all the way through to create a fanned effect. They look cool, but they take some care and precision to prepare. This revised, easier version features potato coins arranged on their sides in a baking pan. Standing the potato slices upright exposes more potato flesh to flavorings
