How to Make Creamy Scalloped Potatoes with Parmesan and Thyme

Creating creamy scalloped potatoes is straightforward with a step-by-step approach. Let’s break down the process:

Preheat your oven to 400°F (200°C) and prepare a ceramic baking dish by lightly greasing it.
Gather and peel 5 pounds of Yukon gold potatoes, slicing them to about 1/16 inch for even cooking.
In a large pot, melt 2 tablespoons of unsalted butter over medium heat. Add 2 cloves of minced garlic, cooking for about 1 minute until fragrant.
Stir in 1 tablespoon of all-purpose flour, cooking for another 1-2 minutes to form a roux, which thickens your sauce.
Gradually whisk in 1 cup of heavy cream until the mixture is smooth and slightly thickened, which will take around 5 minutes.
Incorporate ½ cup of grated Parmesan cheese, 1 teaspoon of fresh thyme, ½ teaspoon of kosher salt, and ½ teaspoon of black pepper until fully blended.
Toss the potato slices in the cheese sauce to ensure each slice is coated evenly and flavorful.
Neatly arrange the coated potato slices upright in the greased baking dish, pouring any remaining sauce over the top and sprinkling more Parmesan cheese.
Cover the dish with foil to keep moisture in and bake for 30 minutes.
Remove the foil, continue baking for an additional 30 minutes until the top is crisp and golden brown, and the sauce is bubbling.
Allow the dish to rest for about 10 minutes before serving, letting the sauce thicken for easy serving.
