Step-by-Step Instructions
- Wash, peel, and thinly slice the russet potatoes using a sharp knife or mandoline for uniformity. Place the potatoes in a bowl of cold water to prevent browning.
- In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in 1/4 cup of all-purpose flour and stir for about 2 minutes until it forms a smooth paste. Gradually pour in 2 cups of whole milk and 1 cup of heavy cream, whisking constantly for about 5 minutes until thickened.
- Remove from heat and stir in 1 teaspoon of salt, 1/2 teaspoon of black pepper, 1 teaspoon of garlic powder, and 1 teaspoon of paprika. Fold in 2 cups of shredded cheddar cheese until completely melted and smooth.
- Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish. Layer half of the sliced potatoes in the dish, pour half of the creamy sauce over them, and repeat with remaining potatoes and sauce.
- Sprinkle 1/2 cup of grated Parmesan cheese and any reserved cheddar cheese on top. Cover tightly with aluminum foil and bake for 40 minutes.
- Remove the foil and bake uncovered for an additional 20 minutes until the top is golden brown and bubbling.
- Let the potatoes rest for 10 minutes before serving.

Notes
Ensure potato slices are thin for uniform cooking and use fresh shredded cheese for the best results. Cover while baking to retain moisture and rest after baking for easy serving.
