Recipe Information
Ingredients
- 6 medium-sized Russet or Yukon Gold potatoes
- 4 tablespoons Butter
- 2 tablespoons All-purpose flour
- 1.5 cups Milk
- 2 cups Cheddar cheese, shredded
- 1 cup Sour cream
- 1 teaspoon Salt
- 0.5 teaspoons Black pepper
- 0.5 teaspoons Garlic powder
- 0.5 teaspoons Paprika (optional, for garnish)
- 2 tablespoons Green onions, chopped (optional, for garnish)
Instructions
Preheat your oven to 375°F (190°C) and grease a 9x13-inch casserole dish.
Peel the potatoes and slice them thinly, about 1/8-inch thick, using a knife or mandoline slicer. Set aside.
In a medium saucepan over medium heat, melt the butter. Once melted, whisk in the flour and cook for 1 minute to make a roux.
Gradually add the milk to the roux, whisking constantly to avoid lumps. Cook the mixture, stirring often, until it thickens, about 2-3 minutes.
Turn off the heat and stir in 1 1/2 cups of the shredded cheddar cheese, sour cream, salt, black pepper, and garlic powder. Mix until the cheese is fully melted and the sauce is smooth.
Layer half of the sliced potatoes evenly in the greased casserole dish. Pour half of the cheese sauce over the potatoes, spreading it evenly.
Repeat with the remaining potatoes and cheese sauce, ensuring all surfaces are coated.
Sprinkle the remaining 1/2 cup of shredded cheddar cheese on top.
Cover the casserole dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the top is bubbly and golden brown.
Remove the casserole from the oven and let cool for 5-10 minutes. Garnish with paprika and chopped green onions, if desired, before serving.
