Recipe Information
Ingredients
- 6 medium-sized russet potatoes
- 4 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 2 cups shredded cheddar cheese
- 1 cup sour cream
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon garlic powder
- 0.5 cup panko breadcrumbs
- 1 tablespoon olive oil
- 2 tablespoons chopped fresh parsley (optional)
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish and set aside.
Peel the potatoes and slice them thinly (about 1/8 inch thick). Use a mandoline slicer for even slices if available.
In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook for 1-2 minutes, stirring constantly, until a smooth paste forms.
Gradually add the milk to the butter-flour mixture, whisking constantly to avoid lumps. Cook the sauce for 3-5 minutes, until it thickens.
Remove the saucepan from heat and stir in 1.5 cups of shredded cheddar cheese until melted. Add the sour cream, salt, pepper, and garlic powder, mixing until smooth.
Layer half of the sliced potatoes in the prepared baking dish. Pour half of the cheese sauce over the potatoes, spreading it evenly.
Repeat with the remaining potatoes and cheese sauce, ensuring the top layer is fully coated.
In a small bowl, mix the panko breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole.
Bake in the preheated oven for 40-45 minutes, or until the potatoes are tender, the top is golden brown, and the casserole is bubbling around the edges.
Let the casserole cool for 5-10 minutes before serving. Garnish with chopped fresh parsley if desired.
