Instructions

Preheat the oven to 375˚F.
Wash and peel the potatoes.
With a knife or a mandolin, finely slice the potatoes about 1/8 inch thin. Try to make them uniform in size so that they cook evenly.

Once the butter is melted add the flour and stir to combine. Continue cooking for 2 minutes.
Add the milk, onion powder, salt, and pepper, and whisk until the sauce has thickened.
Add the cheese and stir until the cheese is melted. Remove from heat.
Pour the sauce over the potatoes. Cover with aluminum foil.
Place the dish in the oven and cook for 45 minutes.
Remove the aluminum foil and continue cooking for an additional 15 minutes.
Remove from the oven and sprinkle with fresh parsley.
Allow the potatoes to cool, sitting at room temperature for 10 minutes before serving.
