Recipe Information
Ingredients
- 6 pieces medium-sized potatoes
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 2 cups shredded cheddar cheese
- 1 cup sour cream
- 0.5 cup chopped green onions
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 0.5 teaspoon garlic powder
- 1 cup breadcrumbs
- 1 tablespoon olive oil
Instructions
Preheat your oven to 350°F (175°C).
Peel and slice the potatoes thinly, about 1/4 inch thick.
In a medium saucepan over medium heat, melt the butter.
Whisk in the flour and cook for about 1 minute to form a roux.
Slowly whisk in the milk, ensuring to break up any lumps, and bring to a gentle simmer.
Add 1.5 cups of shredded cheddar cheese to the mixture, stirring continuously until the cheese is melted and the sauce is smooth.
Stir in the sour cream, chopped green onions, salt, black pepper, and garlic powder, then remove from heat.
Layer half of the sliced potatoes evenly in a greased 9x13 inch baking dish.
Pour half of the cheese sauce over the potatoes, spreading evenly.
Repeat with remaining potatoes and cheese sauce, ensuring all potatoes are covered.
In a small bowl, combine breadcrumbs and olive oil, mixing until evenly moistened.
Sprinkle the breadcrumb mixture over the top of the casserole, followed by the remaining 0.5 cups of shredded cheddar cheese.
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 25-30 minutes, or until the top is golden and bubbly, and the potatoes are tender.
Let the casserole cool for about 10 minutes before serving.
