Gratin Dauphinois at Le Fantin Latour
Gratin dauphinois — thinly sliced Agria potatoes slow-baked in cream and garlic until golden and trembling — is Grenoble's most beloved dish, and chef Christophe Aribert's restaurant Le Fantin Latour on the Isère riverbank is widely regarded as the most refined place to eat it in its home city.
The Dish and Its Rules
Authentic gratin dauphinois contains no cheese — that's the Savoyard version. The Dauphiné original is purely potatoes, cream, garlic and nutmeg, cooked low and slow until the cream reduces to a rich, barely-set custard. Any Grenoblois will tell you this with some passion if you order the wrong version.
Le Fantin Latour elevates the dish without distorting it: the potatoes are sourced from local farms, the cream is full-fat and unpasteurised where possible, and the gratin arrives in its individual copper dish still bubbling. It is served as a side to roasted Alpine lamb or veal, but you can absolutely order it alone as a starter.
The Broader Menu and Setting
The restaurant occupies a graceful Belle Époque building at 1 Rue Gentizon, with a dining room of parquet floors, high ceilings and large windows overlooking the Isère. The menu rotates with the seasons and leans into the Dauphiné larder: Chartreuse-cured salmon, Vercors blue cheese soufflé, walnut tart with crème fraîche.
For a more casual version of the same cooking philosophy, the attached bistro Le Grill serves a shorter menu at lower prices — the gratin dauphinois features there too, alongside a good selection of Rhône and Savoie wines by the glass.
