Ingredients
Potatoes and Onion
- 4 russet potatoes, peeled and sliced into ¼-inch slices (about 2 pounds)
- 1 yellow onion, sliced into rings
Sauce
- 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
- Prepare the vegetables: Peel the russet potatoes and slice them into ¼-inch thick slices. Slice the yellow onion into rings as well. Set aside.
- Make the roux: In a medium saucepan, melt the unsalted butter over medium heat. Once melted, whisk in the all-purpose flour and kosher salt, cooking for about 1-2 minutes until the mixture forms a lightly golden paste and loses its raw flour taste.
- Add milk and thicken sauce: Gradually whisk in the room temperature whole milk to the roux, stirring constantly to avoid lumps. Continue cooking and whisking for 5-7 minutes until the sauce thickens to a creamy consistency.
- Add cheese: Remove the sauce from heat and stir in 1 ½ cups of shredded mild cheddar cheese until melted and fully combined. Taste and adjust seasoning with salt and pepper as desired.
- Assemble the casserole: In a greased baking dish, layer half of the sliced potatoes evenly. Top with half of the sliced onion rings, then pour half of the cheese sauce over the top. Repeat with remaining potatoes, onions, and cheese sauce, ensuring the last layer is coated with the cheese sauce.
- Bake: Preheat your oven to 350°F (175°C). Cover the baking dish with foil and bake for 45 minutes. Remove the foil and continue baking for an additional 20-25 minutes until the potatoes are tender and the top is golden and bubbly.
- Rest and serve: Allow the scalloped potatoes to rest for about 10 minutes before serving to let the sauce set slightly for easier slicing and better texture.
Notes
- For an extra crispy topping, sprinkle additional shredded cheese or breadcrumbs on top before the final bake.
- You can substitute the whole milk with 2% milk for a slightly lighter version.
- Letting the dish rest after baking helps the sauce thicken and improves slicing.
- This recipe can be prepared a day ahead and reheated before serving.
