Ingredients
4 russet potatoes (about 2 pounds), peeled and sliced into ¼-inch slices
1 yellow onion, sliced into rings
3 tablespoons unsalted butter
3 tablespoons all-purpose flour
½ teaspoon kosher salt
2 cups whole milk, at room temperature
1½ cups mild cheddar cheese, shredded
Salt and pepper, to taste
Instructions
Preheat Oven & Prepare Dish:
Preheat oven to 400°F (200°C). Lightly spray an 8×8-inch casserole dish with nonstick cooking spray.
Layer Potatoes and Onions:
In the prepared dish, layer potato slices and onion rings alternately, slightly overlapping.
Make Cheese Sauce:
In a medium saucepan, melt butter over medium heat. Stir in flour and ½ tsp salt, whisking constantly for 1 minute.
Gradually whisk in the milk. Cook, stirring constantly, until the sauce thickens, about 3–5 minutes.
Add Cheese:
Stir in all the shredded cheddar cheese at once. Stir until completely melted and smooth (30–60 seconds).
Assemble and Bake:
Pour the cheese sauce evenly over the potatoes and onions. Cover the dish with aluminum foil.
Bake for 85–90 minutes or until potatoes are tender when pierced with a fork.
Broil for a Golden Top (Optional):
For a golden, crispy topping, broil the dish for 2–3 minutes after baking until the surface is lightly browned.
Serve:
Season with salt and pepper to taste and serve hot.
Notes
Let the dish rest for 10 minutes after baking for easier slicing.
Use sharp cheddar for a bolder cheese flavor.
Add chopped herbs (like thyme or chives) for extra depth.
Can be doubled and baked in a 9×13-inch pan for a larger crowd.
