Macaroni au Gratin

Macaroni au Gratin (macaroni beneath a cheese-and-bread crust) teaches that a gratin is not a casserole left in the oven until tired. It is a finish: the interior arrives already hot and coherent, then a fierce burst of heat bronzes a thin top before the macaroni dries. The raspings matter more than their modest name suggests. Cheese alone melts, tightens, and can turn leathery; bread raspings mixed with butter give the crust bite.

The classical entry assumed Macaroni à l’Italienne (No. 2285) ready from the sautépan, a saucier holding Béchamel, brigade portions, and a salamander or fierce range waiting for Gratins (No. 268). At home, the separate hands and oversized quantities are scaffolding, so they go. A shallow two-quart dish, an upper oven rack, and a brief broiler finish do the same work for four. What stays is the dish itself: only enough Béchamel to loosen, real butter, cheese above and below, raspings across the surface, and hard heat at the end. One cook, one stove, one evening.

Have both macaroni and Béchamel warm before they meet, then stop adding sauce as soon as the pasta settles in a glossy mound. A flooded base cannot support a crisp crown. The one step that decides this dish is the topping: mix the raspings with cheese and melted butter before scattering it, then bake at once.
