Ingredients
Units
Scale
- 4 russet potatoes, peeled and sliced into 1/4-inch slices (about 2 pounds)
- 1 yellow onion, sliced into rings
- 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
- Salt and pepper to taste
Instructions
- Preheat Oven: Preheat oven to 400°F. Lightly spray an 8×8-inch casserole dish with nonstick cooking spray.
- Layer Potatoes and Onions: Arrange the potatoes and onions in the prepared baking dish, alternating layers of potato and onion.
- Prepare Cheese Sauce: Melt butter in a medium saucepan over medium heat. Stir in the flour and salt, whisking constantly for 1 minute. Gradually add the milk, cooking until thickened.
- Melt Cheese: Stir in the shredded cheddar cheese, continuing to stir until the sauce is melted and smooth (about 30–60 seconds).
- Assemble and Bake: Pour the cheese sauce evenly over the potatoes. Cover the dish with aluminum foil and bake for 85–90 minutes, or until the potatoes are tender.
- Optional Broil: For a golden, crispy top, switch the oven to broil after baking and broil until golden brown.
- Season and Serve: Add salt and pepper to taste and serve warm.
Notes
- Cheese Options: Substitute cheddar with Gruyère or Monterey Jack for a richer flavor.
- Make Ahead: Prepare the dish up to a day in advance, cover, and refrigerate. Bake just before serving.
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave.
