A comforting soup with a perfectly browned gratin Soups and stews
Onion soup is one of the most emblematic dishes of French cuisine. With gently caramelized onions, a broth rich in flavour, toast and a generous layer of cheese au gratin, it offers a simple yet incredibly comforting meal.
Traditionally, the au gratin finish is done under the broiler of the oven. But thanks to the Air Fryer, it is now possible to achieve an even more golden, crispy and melt-in-your-mouth crust in just a few minutes. The cheese bubbles, takes on a beautiful amber colour and forms that gourmet layer that makes all the charm of the recipe.
Perfect for chilly evenings, a family dinner, or a cocooning meal, this Air Fryer Onion Soup au Gratin is as elegant as it is easy to prepare.
