Ingredients
 

  • 4 tablespoons butter
  • ¼ cup flour
  • 1 ½ teaspoons salt
  • ¼ teaspoon pepper
  • 3 cups milk
  • 3 lbs. potatoes peeled and sliced into ⅛" slices
  • ½ large onion thinly sliced

Instructions
 

  • Preheat your oven to 350°F (176°C) and lightly grease an 8" x 8" baking dish.
  • In a small saucepan melt the butter and then whisk in the salt, pepper and flour until it is smooth. Gradually whisk in ½ cup of milk until there are no lumps. Add the remaining milk and whisk until smooth. Bring the mixture to a boil, stirring constantly. Once the mixture has thickened, remove the saucepan from the heat.
  • Arrange ⅓ of the potato slices on the bottom of the baking dish followed by ⅓ of the onion slices and ⅓ of the sauce. Repeat for two more layers.
  • Loosely tent a piece of foil over the baking dish and bake for 75 minutes. Remove the foil and bake 15 more minutes. Use a fork to test the potatoes for doneness. If the fork does not easily pierce the potatoes, continue to bake until they are done.
