3.
Melt butter in a medium saucepan over medium heat. Gradually whisk in flour and salt and cook, whisking constantly until raw flour flavor has cooked off, about 1 minute. Gradually add milk, about 1/4 cup at a time, whisking well after each addition to incorporate; the gradual addition and whisking of milk will help avoid lumps in your sauce.

Cook, whisking constantly, until the mixture has thickened, 3 to 5 minutes. Stir in cheese all at once; continue stirring until melted, 30 to 60 seconds. Pour cheese sauce over the potatoes, and cover the dish with aluminum foil.
I recommend greasing the aluminum foil as to keep the foil from sticking to the cheesy topping.

5.
Bake in the preheated oven until potatoes are tender and sauce is bubbly, about 1 ½ hours.
For extra crispy top - set oven to broil and remove aluminum foil. Keep in oven on broil until tops of the potatoes are toasted to your preference.
