Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or non-stick spray.
Peel the potatoes and slice them thinly (about 1/8-inch thick) using a sharp knife or a mandoline slicer. Set aside in a bowl of cold water to prevent browning.
In a medium saucepan, melt the butter over medium heat. Mince the garlic and add it to the melted butter. Cook for 1 minute until fragrant.
Add the heavy cream, milk, salt, pepper, and nutmeg to the saucepan. Stir and heat gently until the mixture is warm but not boiling.
Gradually add 1 cup of the shredded Gruyère cheese and all of the Parmesan cheese to the cream mixture, stirring until melted and smooth. Remove the sauce from the heat.
Drain the potato slices and pat them dry with a clean kitchen towel.
Layer one-third of the potato slices evenly in the bottom of the prepared baking dish. Pour one-third of the cheese sauce over the potatoes. Repeat this process for two more layers, finishing with cheese sauce on the top.
Sprinkle the remaining 0.5 cups of Gruyère cheese over the top layer. If desired, add fresh thyme for an aromatic touch.
Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes.
Remove the foil and bake for an additional 30 minutes, or until the potatoes are tender and the top is golden and bubbly.
Let the potatoes au gratin rest for 10 minutes before serving. This allows the layers to set slightly and makes serving easier.
