The timeless classic of gratin dauphinois

Gratin dauphinois, a rustic and comforting dish, is an integral part of French culinary heritage. Its popularity remains strong and making it at home makes it even more delicious. But how can you succeed with this recipe? Chef Christophe shares his secrets.

The key to success: good ingredients

According to the chef, the first thing to know is that all the ingredients matter. Contrary to popular belief, traditional gratin dauphinois does not contain cheese. As the chef states: “There is no cheese in gratin dauphinois.”

The essential ingredients are milk, cream, potatoes, salt, pepper, nutmeg, a clove of garlic, and butter. He also recommends using whole milk and cream to achieve soft and creamy potatoes.

Selecting and preparing the potatoes

The choice of potatoes is crucial. They should be both firm and starchy. As the chef points out: “You need potatoes that will hold up in cooking but will still release starch.” Once peeled, he advises keeping them in water to prevent them from turning black.

For slicing, 3mm slices are ideal. After slicing, do not rinse the potatoes to retain the surface starch, essential for binding the milk and cream.

Assembling and baking the gratin

Assembling the gratin is a delicate step. The chef recommends rubbing half a clove of garlic on the bottom of the dish, then generously buttering. Seasoning is added, followed by arranging the potato slices. The dish is then covered with milk and cream.

The baking time varies between 1h30 and 2h30, depending on the size of the gratin. To check for doneness, the chef suggests using the tip of a knife: “It should go in without any resistance.” And if the gratin is too liquid or dry? Don’t panic, a few adjustments will save it. As Chef Christophe concludes: “Gratin dauphinois is never a failure!”
