A luxurious gratin of wafer-thin potato slices slowly baked in garlic-scented cream until the top blisters golden and the interior turns silky. No cheese, no flour — just potato starch thickening the cream into something between a custard and a confit. The benchmark French potato dish, served beside roast meats across the country.
From the Dauphiné region of south-eastern France; the name first appears in 1788 records of a meal served by the Lieutenant General of Dauphiné, and the cream-only formula is enshrined in classic French cookery.
The top layer crackles like burnt cream, giving way to potatoes so soft they almost melt against the spoon. Each forkful is rich, garlicky and faintly sweet from the slow-cooked dairy, with nutmeg humming underneath. It eats like the most grown-up comfort food imaginable.
Unrinsed potato starch leaches into the cream during baking and gelatinises, thickening the liquid into a clinging sauce without any flour. The long, gentle heat fully softens the potato cells while the exposed surface caramelises into the signature crust.
Variations
Some cooks rub in a little Gruyère for a gratin savoyard, add a beaten egg for extra set, or pre-simmer the slices in the milk to shorten baking.
