- In a medium saucepan, melt the butter over medium heat. Add the minced garlic and sauté until fragrant, about 30 seconds. Sprinkle in the flour and whisk for a minute to create a roux.
- Slowly pour in the heavy cream, whisking constantly until smooth and slightly thickened (2–3 minutes). Season with salt and pepper.
- Grease your baking dish with butter. Arrange half the potato slices in overlapping layers. Pour half of the cream mixture over the top, then sprinkle with half the Gruyère and Parmesan. Repeat the layers.
