Ingredients
  

For the Potatoes
  • 2 pounds Yukon Gold Potatoes Can substitute with Russet potatoes for fluffiness.
For the Cheese Sauce
  • 1 cup Sharp Cheddar Cheese Provides a robust flavor; substitute with medium cheddar for milder taste.
  • 1 cup Gruyère Cheese Contributes nutty flavor; Fontina cheese can be used for a similar melting quality.
  • ¼ cup All-Purpose Flour Can use gluten-free flour blend or cornstarch for gluten-free version.
  • 2 cups Milk Whole or heavy cream; plant-based milk is a great dairy-free option.
  • 4 tablespoons Butter Can be replaced with olive oil for a dairy-free alternative.
For the Topping

Cooking Steps
  1. Preheat your oven to 375°F (190°C).
  2. Melt 4 tablespoons of butter in a medium saucepan over medium heat. Whisk in ¼ cup of flour until smooth, then gradually add 2 cups of milk until thickened. Stir in 1 cup each of shredded cheddar and Gruyère until melted.
  3. Thinly slice 2 pounds of Yukon Gold potatoes into ⅛-inch slices. Layer half in a greased 9x13-inch baking dish.
  4. Cover potatoes with half of the cheese sauce, then layer remaining potatoes and pour the rest of the sauce over top.
  5. Sprinkle ½ cup of breadcrumbs evenly over the final cheese layer.
  6. Cover with aluminum foil and bake for 45 minutes. Remove foil and bake for an additional 15-20 minutes until golden brown.
  7. Let dish rest for 10 minutes before serving. Garnish with chopped chives.
