Preheat your oven to 375°F (190°C).
Peel the potatoes and slice them thinly, about 1/8 inch thick. Place the sliced potatoes in a bowl of cold water to prevent browning.
Mince the garlic clove finely.
In a saucepan over medium heat, combine the heavy cream, minced garlic, a pinch of salt, and a pinch of nutmeg. Bring to a simmer and then remove from heat.
Drain the potatoes and pat them dry with a clean kitchen towel or paper towels.
Layer half of the potato slices in a greased baking dish, slightly overlapping them. Pour half of the warm cream mixture over the potatoes and sprinkle with half of the grated Gruyère cheese.
Repeat with the remaining potato slices, cream mixture, and Gruyère cheese.
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and continue to bake for another 30 minutes or until the top is golden brown and the potatoes are tender when pierced with a knife.
Let the gratin rest for a few minutes before serving.
