Instructions:
- Preheat the oven to 350°F (175°C) and generously butter a baking dish.
- In a saucepan over medium heat, melt the butter and sauté the garlic for about 30 seconds until fragrant.
- Add the heavy cream, milk, salt, pepper, and nutmeg. Heat gently until warm, but do not boil. Remove from heat.
- Arrange half of the sliced potatoes evenly in the prepared baking dish.
- Pour half of the warm cream mixture over the potatoes, then sprinkle with half of the Gruyère and some of the Parmesan.
- Repeat with the remaining potatoes, cream mixture, and cheeses.
- Cover the dish tightly with foil and bake for 45 minutes.
- Remove the foil and bake for an additional 15 minutes, until bubbling and lightly golden on top.
- Let the scalloped potatoes rest for 10 minutes before serving.
- Garnish with fresh herbs if desired and serve warm.
Variations
- Add thinly sliced shallots between layers for subtle sweetness.
- Substitute fontina for part of the Gruyère for extra meltiness.
- Stir a small amount of Dijon mustard into the cream for depth.
- Use smoked Gruyère for a more robust steakhouse flavor.
Tips
- Slice the potatoes very thin and evenly for the smoothest texture.
- A mandoline works best for consistent slices.
- Warm the cream mixture before layering to ensure even cooking.
- Resting the dish before serving is essential for a thick, cohesive sauce.
