Method
Preparation
- Preheat the oven to 375°F (190°C).
- Peel the potatoes and slice them into 1/8 inch rounds. Place the slices in a bowl of cold water to prevent browning.
- In a medium bowl, whisk the heavy cream with garlic powder, salt, black pepper, and nutmeg until smooth.
- Butter a 9x13-inch baking dish. Arrange half of the potato slices in an even layer across the bottom.
- Scatter half the sliced onion over the potatoes. Pour half of the cream mixture over this layer, then sprinkle half of the shredded cheddar evenly.
- Repeat with the remaining potatoes, onion, cream, and cheddar. Smooth the top with a spatula.
- Sprinkle the optional Parmesan over the surface if using.
Cooking
- Cover the dish tightly with foil and bake for 45 minutes.
- Remove the foil and return the dish to the oven. Bake an additional 30 to 35 minutes, until the top is golden and a knife slides easily into the potatoes.
- Let the casserole rest for 10 minutes before serving to allow the cream to settle.
