Ingredients
•
3 pounds potatoes, thinly sliced
•
1/2 onion, thinly sliced
•
9 tablespoons all-purpose flour, divided
•
6 tablespoons butter, diced and divided
•
salt and ground black pepper to taste
•
3 cups whole milk, or as needed
Directions
1
Gather the ingredients. Preheat the oven to 375 degrees F (190 degrees C). Grease a 9x13-inch baking dish.
2
Arrange about ⅓ potato slices in the bottom of the prepared baking dish; top with about ⅓ onion slices. Sprinkle 3 tablespoons flour over potato and onion layer; place 2 tablespoons cubed butter on top. Season layer with salt and black pepper. Repeat layering twice more.
3
Heat milk in a saucepan over medium-low heat until warm. Pour enough warm milk over mixture in the baking dish until top of the liquid is level with the final layer of potatoes.
4
Bake in the preheated oven until potatoes are tender and sauce is bubbling with a golden brown crust, 45 to 60 minutes. Place a baking sheet underneath the baking dish to catch any drips; the sauce may bubble up over the sides. Serve hot and enjoy!
