History and recipe of the classic French gratin casserole

This is one of the most well-known casseroles in the world. Its base consists of potatoes, while the remaining ingredients include spices and cream. The simplicity is what makes this dish so ingenious. Try it, and you'll love it from the first bite.

The history of gratin casserole is tied to the Dauphiné region in southeastern France. In the 16th century, potatoes were brought there by Spanish conquistadors from South America. Although this vegetable did not gain popularity on the Iberian Peninsula, it reached France via Italy and Switzerland.

In Dauphiné, potatoes quickly gained recognition as a valuable food product. As early as the 17th century, they began to be used in various ways. The first mention of gratin, however, appeared only in July 1788, when Charles-Henri, Duke of Clermont-Tonnerre, served this dish at a ceremonial dinner for officials from Gap. The potato casserole, served with roasted ortolans and small migratory birds, made a huge impression on the guests.

The basic ingredient of gratin is potatoes. The best ones are type A or B, meaning they have flesh that doesn’t fall apart during thermal processing. Additionally, the French casserole won’t do without thick, heavy cream, preferably crème fraîche. It has a velvety consistency, buttery aroma, and slightly tangy taste. It contains up to 45% milk fat, so it doesn’t curdle at high temperatures.

Although cheese isn’t added in the traditional version of gratin, many chefs recommend adding it to enrich the dish's flavor. Swiss gruyère is recommended, but cheddar or high-quality yellow cheese also works well. It will form a golden crust on the surface of the casserole.

Ingredients:

• 2.2 lbs of potatoes
• 1-2 cloves of garlic
• butter for greasing the dish
