Ingredients
  

Main Ingredients
  • 4 russet potatoes peeled and sliced into ¼-inch slices (about 2 pounds)
  • 1 yellow onion sliced into rings
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • ½ teaspoon kosher salt
  • 2 cups whole milk room temperature
  • 1 ½ cups mild cheddar cheese shredded
  • salt and pepper to taste

Equipment

  • 8×8-inch Casserole Dish
  • Medium-size Saucepan

Method
 

  1. Preheat oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray.
  2. Arrange the potatoes and onions in the prepared baking dish, staggering potato and then onion.
  3. In a medium-size saucepan, melt butter over medium heat. Mix in the flour and salt, and stir constantly with a whisk for one minute. Stir in milk. Cook until mixture has thickened.
  4. Stir in cheese all at once, and continue stirring until melted and smooth, about 30-60 seconds.
  5. Pour the cheese sauce over the potatoes, and cover the dish with aluminum foil.
  6. Bake for 85-90 minutes, or until the potatoes are tender.
  7. For a crisp topping, change the oven setting to broil after the potatoes are baked. Broil until golden brown.
  8. Season with salt and pepper to taste and serve.
