french potato gratin dauphinois recipe

Here is one of my favorite recipes for the winter season: le gratin dauphinois (au gratin potatoes in English). This French recipe is very easy to cook and it’s so delicious! My favorite gratin dauphinois recipe is the one from the well-known chef Alain Ducasse. By the way, if you’re looking for a French cookbook with simple recipes for every day (without the fat and without the fuss), I really recommend his book: Simple, Healthy, and Good.

What is a Gratin Dauphinois?

A gratin dauphinois is a traditional French dish from the Dauphiné region in south-eastern France. The potatoes are peeled and sliced to the thickness of a coin, usually with a mandoline; they are layered in a gratin pan and cooked in a slow oven.

The first mention of the dish is from 1788 as it was served at a dinner offered to municipal officers of the city of Gap. This dish was traditionally eaten by the peasants in the Dauphiné region which is a mountainous region.

This traditional potato dish is usually eaten on its own with a green salad. There are several variations: some add onions, ham, or cheese (gruyere), however, the traditional recipe does not contain these. You can adapt the recipe given and personalize it as you wish!
