Ingredients
Potatoes
5 pounds Yukon Gold potatoes
Sauce
2 tablespoons unsalted butter
2 cloves garlic (minced or pressed)
1 tablespoon all purpose flour
1 cup heavy cream (substitute whole milk or half and half)
1/2 cup Parmesan cheese (optional)
1 teaspoon fresh thyme
1/2 teaspoon kosher salt
1/2 teaspoon black pepper
Instructions
Preheat oven and prepare baking dish: Heat the oven to 400°F and lightly grease a medium sized ceramic baking dish to prevent sticking.
Slice potatoes: Using a mandolin or sharp knife, slice the Yukon Gold potatoes as thinly as possible, about 1/16th of an inch, for even cooking and layering.
Melt butter and cook garlic: In a large pot over medium heat, melt the butter and sauté the minced garlic until it is fragrant and aromatic, about 1-2 minutes.
Create roux and thicken sauce: Stir in the all purpose flour to the butter garlic mixture to form a roux and cook for 1-2 minutes. Gradually stir in the heavy cream and continue stirring until the sauce thickens, about 5 minutes.
Add seasonings and cheese: Stir in the Parmesan cheese, fresh thyme, kosher salt, and black pepper until the sauce is smooth and well combined.
Cool sauce: Remove the pot from heat and allow the cream sauce to cool slightly to prevent cooking the potatoes prematurely when combined.
Coat potatoes with sauce: Place the sliced potatoes in a large bowl and pour the cream sauce over them. Gently toss to ensure all potato slices are evenly coated.
Arrange potatoes in baking dish: Stack the coated potato slices upright in the prepared baking dish. Pour any leftover sauce over the top and sprinkle extra Parmesan if desired for a cheesy crust.
Bake covered: Tent the baking dish with aluminum foil and bake at 400°F for 30 minutes to start the cooking process and allow potatoes to soften.
Bake uncovered: Remove the foil and continue baking uncovered for an additional 30 minutes or until potatoes are golden brown on top and cooked through.
Rest and serve: Remove the scalloped potatoes from the oven and let them cool for about 10 minutes before serving to allow the sauce to thicken further and enhance flavor.
Notes
Use a mandolin for perfectly thin and even potato slices to ensure even cooking.
You can substitute whole milk or half and half for the heavy cream to reduce fat.
Adjust salt and pepper to taste depending on your seasoning preference.
Let the dish rest before serving for the best creamy texture.
For a richer topping, sprinkle extra Parmesan cheese before baking uncovered.
