Gratin de Crozets

Gratin de crozets is a winter gratin of the Savoy region, built around crozets — small flat squares of buckwheat pasta. Crozets themselves are attested in the Tarentaise valley of the Savoy as far back as the seventeenth century. The buckwheat — sarrasin — was historically a staple crop of the Alpine valleys, where wheat grew poorly; grinding it into pasta gave a form that would keep through the winter. The gratin preparation layers the cooked crozets with cream, mountain cheese — typically Beaufort or Reblochon — and lardons or diots, bakes the whole until the surface browns, and serves it hot as a substantial mountain main. A cheese-and-lardon variant is sometimes nicknamed croziflette, by analogy with tartiflette.

A spoonful of gratin de crozets brings up tender square pasta bound in a thick, glossy cream-and-melted-cheese sauce, with small chewy nuggets of buckwheat pasta and salty bursts of lardon. The surface is browned and crisp; the interior is soft, rich, and earthy from the buckwheat. The flavor is unmistakably Alpine — nutty cheese, cured pork, and the dark, almost bitter note of the buckwheat underneath.

Gratin de crozets combines two mechanisms: starch gelatinization in the pasta and Maillard browning on the surface. The crozets — made from buckwheat flour, often blended with wheat — are first boiled, which hydrates and gelatinizes their starches, giving the pasta its soft, chewy structure. Buckwheat is naturally low in gluten-forming proteins, which is what lets these little squares stay tender rather than turning tough, and gives them their characteristic nutty, earthy flavor. The gratin step then layers the cooked pasta with cream and grated mountain cheese and bakes it: in the oven, the dairy fat melts and emulsifies with the residual pasta water, coating each piece, while the surface undergoes Maillard browning under dry heat to form the golden, crisp crust that defines a gratin.
