A dish prepared in the Savoy region of the French Alps. It is nice with white wine and keeps you warm. My guest had 4 helpings last time I made it!

Salt pork drives this entire dish, rendering copious amounts of rendered fat that subsequently transforms standard onions and starchy potatoes into deeply savory components without requiring expensive additional oils. Rendering this cured cut over medium-high heat until golden brown yields crisp lardons while leaving behind ample pan drippings to sweat the aromatics. When selecting a cut at the butcher counter, inspect the ratio of lean meat to fat carefully, ensuring a balanced distribution that provides both rich cooking medium and substantial protein bites.
Parboiling potatoes for no more than fifteen to twenty minutes requires close visual observation rather than strictly relying on a kitchen timer, because tubers vary widely in moisture content and age. Piercing a slice should reveal an exterior that offers slight give while the interior remains completely firm and resistant, preventing the slices from turning to mush when combined with the warm wine reduction later. Cooling the boiled tubers in cold water halts internal residual carryover cooking immediately, locking in the precise structural integrity needed for the baking dish.
Dry white wine deglazes the skillet effectively, dissolving the caramelized fond left behind by the pork and onions to build a concentrated base layer of acidity. Allowing this liquid to reduce almost entirely on high heat concentrates the aromatics so the final casserole avoids excess moisture pooling beneath the melting dairy. Incorporating the crème fraîche directly into this warm skillet mixture coats every potato surface evenly before transferring the contents to the casserole pan.
Baking this heavy casserole covered with aluminum foil at 350 degrees for an exact duration of one hour allows the potatoes to finish cooking through uniformly while absorbing the surrounding fats and dairy. Removing the foil for the final broiling stage exposes the scored cheese crust directly to intense overhead heat, creating a deep golden brown finish that signals the dish is ready for service. Leftovers keep well in an airtight container in the refrigerator for up to three days, often improving in flavor as the starches fully absorb the surrounding seasoned fats.
