Step-by-Step Instructions
- Preheat your oven to 400°F (200°C) and grease a ceramic baking dish with butter or oil.
- Peel and slice the Yukon gold potatoes into 1/8-inch thick pieces and keep them in a bowl of cold water.
- Melt the unsalted butter in a large pot over medium heat, then add the minced garlic and stir for about a minute until fragrant.
- Sprinkle the all-purpose flour over the melted butter and garlic, stirring vigorously for 1-2 minutes to form a roux.
- Gradually whisk in the heavy cream and cook until the mixture thickens slightly, about 5 minutes. Then mix in the Parmesan cheese, thyme, salt, and pepper.
- Add the sliced potatoes to the sauce and gently toss to fully coat each slice.
- Arrange the potato slices upright in the greased baking dish and pour remaining sauce over the top. Sprinkle with extra Parmesan cheese.
- Cover the dish with aluminum foil and bake for 30 minutes, then remove the foil and bake for another 30 minutes until golden and bubbly.
- Allow to cool for about 10 minutes before serving.
