Ingredients
  

Potatoes
  • 2 pounds Russet potatoes peeled and thinly sliced
Cheese Sauce
  • 4 tablespoons unsalted butter for sauce
  • 1/4 cup all-purpose flour for thickening
  • 2 cups whole milk for sauce
  • 1 cup heavy cream for richness
  • 2 cups shredded sharp cheddar cheese for flavor
  • 1 cup shredded Gruyère cheese for depth
  • 1 teaspoon salt to taste
  • 1/2 teaspoon black pepper to taste
  • 1/4 teaspoon nutmeg optional, for flavor
Topping
  • 1 cup panko breadcrumbs for crunch
  • 2 tablespoons unsalted butter melted, for topping
  • 1/2 cup shredded Parmesan cheese for topping

Method
 

Prepare the Potatoes
  1. Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking dish.
  2. Using a mandoline slicer, thinly slice the peeled Russet potatoes.
Make the Cheese Sauce
  1. In a saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes to form a roux.
  2. Gradually whisk in the milk and heavy cream, cooking until the mixture thickens.
  3. Remove from heat and stir in the cheddar and Gruyère cheeses until melted. Season with salt, pepper, and nutmeg.
Assemble the Dish
  1. Layer half of the sliced potatoes in the greased baking dish. Pour half of the cheese sauce over the potatoes.
  2. Repeat with the remaining potatoes and cheese sauce.
  3. In a small bowl, combine the panko breadcrumbs, melted butter, and Parmesan cheese. Sprinkle over the top of the dish.
Bake
  1. Cover the baking dish with aluminum foil and bake for 45 minutes.
  2. Remove the foil and bake for an additional 15 minutes, or until the top is golden brown and the potatoes are tender.
  3. Let it cool for a few minutes before serving.
