A comforting and delicious potato dish with layers of creamy cheese and tender potatoes.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
Peel and thinly slice the potatoes using a mandoline slicer.
Using a mandoline slicer helps achieve uniform slices for even cooking.
Thinly slice the onion and mince the garlic.
Mincing the garlic releases its full flavor.
In a mixing bowl, combine the heavy cream, minced garlic, salt, pepper, and thyme.
Mixing the seasoning with the cream ensures even distribution.
Layer half of the potato slices in a buttered baking dish, followed by half of the onion slices.
Arrange the slices neatly for a better presentation.
Sprinkle half of the cheddar and parmesan cheese over the layer.
Distribute the cheese evenly for consistent flavor.
Repeat the layering process with the remaining potatoes, onions, and cheese.
Ensure the top layer is covered with cheese for a golden crust.
Pour the cream mixture evenly over the layered ingredients.
Pour slowly to allow the cream to seep through the layers.
Cover the dish with aluminum foil and bake for 45 minutes.
Covering the dish prevents the top from browning too quickly.
Remove the foil and bake for an additional 15 minutes to brown the top.
Baking uncovered creates a crispy, golden cheese crust.
Let the dish rest for 5 minutes before serving.
Resting allows the dish to set and makes serving easier.
