What is a gratin?

A gratin is a popular culinary technique and dish originating from French cuisine.

It typically involves layering ingredients, such as vegetables or potatoes, in a baking dish, covering them with a creamy sauce, and baking until the top forms a delicious golden crust.

The term “gratin” comes from the French word “gratter,” meaning “to scrape,” referring to the crispy top that forms during baking.

  • Choose vegan cheese or nutritional yeast to achieve a cheesy flavor without animal products.
