Step-by-Step Instructions
- Preheat your oven to 375°F (190°C).
- Using a mandoline slicer, slice your 2 pounds of potatoes into thin rounds, about ⅛-inch thick. Place them in a bowl of cold water to prevent browning.
- Combine 2 cups of heavy cream (or béchamel sauce) with the finely chopped onion, minced garlic, 1 teaspoon of fresh thyme, and a pinch of nutmeg in a saucepan over medium heat. Stir gently for 5-7 minutes until warm and fragrant.
- Add 1 cup of Gruyère cheese to the warm cream mixture. Stir until melted and creamy.
- In a greased baking dish, layer the sliced potatoes, slightly overlapping them. Pour the cheese sauce evenly over the potatoes.
- Sprinkle additional cheese on top for a crispy finish.
- Bake in the preheated oven for 1 hour and 10 minutes until golden and bubbly.
- Allow to cool for 10-15 minutes before serving to set the layers.

Notes
Ensure potatoes are sliced uniformly for even cooking. Letting the gratin cool before serving helps with cleaner slices.
