6 medium potatoes, peeled and thinly sliced
4 tablespoons butter
3 tablespoos flour
2 1/2 cups milk
2 cups shredded cheese
1/2 teaspoon salt
1/2 teaspoon pepper
Preheat oven to 400 degrees.
Step one: In a skillet or saucepan over medium heat, add the butter and cook until melted and frothy. Add flour and whisk until lightly browned, about 30 seconds. Season with salt and pepper to taste. Whisk in milk until smooth. Increase heat to simmer for about 30 seconds.
Step two: Use an 8 to 9 inch oven safe skillet. Arrange potato slices in skillet so that they slightly overlap. Use 1 1/2 cups of cheese between every second layer of potato. Pour milk mixture into the skillet to coat potatoes. Top potatoes with remaining 1/2 cup cheese.
