Ingredients
Scale
- 4 russet potatoes, peeled and sliced into ¼-inch rounds
- 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
Instructions
- Preheat oven to 400°F (200°C). Grease an 8×8-inch baking dish with non-stick cooking spray.
- Layer the sliced potatoes and onions in the prepared baking dish, staggering each layer of potatoes and onions.
- In a medium saucepan, melt the butter over medium heat. Add the flour and salt, whisking constantly for 1 minute.
- Slowly stir in the milk, cooking until the mixture thickens.
- Stir in the shredded cheddar cheese and continue to stir until melted and smooth.
- Pour the cheese sauce over the layered potatoes and onions, covering evenly.
- Cover the dish with aluminum foil and bake for 85-90 minutes, or until the potatoes are tender.
- If you prefer a crispy topping, switch the oven to broil for 3-5 minutes after baking.
- Season with additional salt and pepper, then serve warm.
Notes
- Using a mandoline to slice the potatoes ensures uniform thickness and even cooking.
- Feel free to swap cheddar for other cheeses such as Gruyère or sharp cheddar for a more robust flavor.
- You can prepare the dish a day ahead of time, covering it tightly and refrigerating before baking.
- To make the dish richer, add a bit more cheese or butter to the sauce.
