Ingredients
  

For the Potatoes and Onions
  • 4 russet potatoes peeled and sliced into 1/4-inch slices (about 2 pounds)
  • 1 yellow onion sliced into rings
For the Cheese Sauce
  • 3 tablespoons unsalted butter
  • 3 tablespoons all-purpose flour
  • 1/2 teaspoon kosher salt
  • 2 cups whole milk room temperature
  • 1 1/2 cups mild cheddar cheese shredded
  • to taste salt and pepper

Equipment

  • 8x8-inch casserole dish
  • medium-size saucepan
  • Whisk
  • Aluminum foil

Method
 

  1. Preheat your oven to 400°F. Lightly spray an 8x8-inch casserole dish with nonstick cooking spray.
  2. Arrange the sliced potatoes and onion rings in the prepared baking dish, staggering them for even cooking.
  3. In a medium saucepan, melt the butter over medium heat. Whisk in the flour and 1/2 teaspoon of kosher salt, stirring constantly for one minute. Gradually stir in the milk. Cook, stirring, until the sauce has thickened.
  4. Remove the saucepan from the heat. Stir in the shredded cheddar cheese all at once, continuing to stir until the cheese is melted and the sauce is smooth, about 30-60 seconds.
  5. Pour the cheese sauce evenly over the potatoes and onions in the baking dish. Cover the dish tightly with aluminum foil.
  6. Bake for 85-90 minutes, or until the potatoes are tender when pierced with a fork.
  7. For a crisp topping, remove the foil and change the oven setting to broil. Broil for a few minutes until the top is golden brown.
  8. Season with additional salt and pepper to taste before serving.
