Classic Scalloped Potatoes
- Preheat Oven & Prep Dish: Preheat your oven to 350°F (175°C). Lightly grease a one-quart casserole dish.
- Make the Cheese Sauce: In a small saucepan, melt the butter over low heat. Whisk in the flour and cook for about one minute. Gradually add the cold milk, stirring continuously with a whisk until the sauce is smooth and lump-free. Season with salt and a dash of cayenne pepper.
- Cook the Sauce & Add Cheese: Increase the heat to medium and continue to cook, stirring with a whisk until the sauce comes to a boil and thickens. Reduce the heat to low and stir in 1 cup of the grated sharp Cheddar cheese until it is completely melted and smooth.
