Dauphinois describes the classic French way of baking thinly sliced potatoes in milk, cream, or a mixture of the two — as in gratin dauphinois, the dish of the Dauphiné region. Raw potatoes are sliced paper-thin, layered in a buttered dish often rubbed with garlic, covered with seasoned cream, and baked slowly until the slices turn meltingly tender and the top browns to a golden crust. The starch released from the cut surfaces thickens the cream into a silky sauce without any added flour. The word on a menu signals richness and comfort rather than lightness: this is a celebration dish, not an everyday side. It belongs to the family of French gratins where a humble ingredient, sliced fine and baked in dairy, becomes something far greater than the sum of its parts.
