Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray.

Step 2: Layer the Potatoes and Onions

Arrange the potatoes and onions in the prepared baking dish, staggering layers of potato slices and onion rings for even distribution.

Step 3: Make the Cheese Sauce

In a medium saucepan, melt butter over medium heat. Mix in the flour and salt, stirring constantly with a whisk for one minute to form a roux. Gradually stir in the milk and cook until the mixture thickens.

Step 4: Add the Cheese

Stir in the shredded cheddar cheese all at once and continue stirring until the cheese melts and the sauce is smooth, about 30-60 seconds.

Step 5: Assemble and Bake

Pour the cheese sauce evenly over the potatoes and onions. Cover the dish with aluminum foil and bake for 85-90 minutes, or until the potatoes are tender.

Step 6: Broil for a Crispy Topping (Optional)

For a crisp topping, change the oven setting to broil after baking. Broil until the surface is golden brown.

Step 7: Season and Serve

Season with salt and pepper to taste before serving.
