Ingredients

cooking spray
3 tablespoons butter
¼ cup finely diced onion
2 tablespoons flour
¼ teaspoon salt
⅛ teaspoon pepper
1 ⅔ cup milk
4 cup thinly sliced potatoes about 5 medium
1 ½ cup grated cheddar cheese

Instructions

Peel and slice potatoes; set aside.
Preheat oven to 350°. Spray a 2 quart casserole dish or large pie pan with cooking spray.
In a medium sauce pan melt butter over medium heat. Add onions and cook until tender, about 4-5 minutes. Whisk in flour, salt and pepper; cook for 1-2 minutes. Whisk in milk and heat to a boil, stirring constantly, cook one minute or until thick and bubbly. Stir in 1 cup cheese and stir until melted.
Cover bottom of prepared baking dish with about ¼ of the sauce, then about ⅓ of the potatoes, repeat layers ending with the sauce.
Cover with aluminum foil and bake for 30 minutes, uncover and top with remaining ½ cup cheese. Bake another 30 minutes until the potatoes are tender and the cheese starts to turn golden brown in spots.
Let stand 5-10 minutes (sauce will thicken as it cools).
