Step-by-Step Instructions
- Preheat your oven to 375°F (190°C).
- Thinly slice your Yukon Gold potatoes using a sharp knife or mandoline.
- In a medium saucepan over medium heat, melt 4 tablespoons of butter. Add 1/4 cup of all-purpose flour and whisk to form a smooth paste.
- Gradually pour in 2 cups of milk while whisking. Cook and stir for 5-7 minutes until thickened. Stir in 1 cup of shredded sharp cheddar and 1 cup of Gruyère until melted.
- In a greased 9x13 inch baking dish, layer half of the sliced potatoes, then pour half of the cheese sauce over them.
- Repeat with remaining potatoes and sauce.
- Sprinkle 1 cup of breadcrumbs over the top.
- Cover with foil and bake for 45 minutes.
- Remove foil and bake for an additional 15-20 minutes until golden brown and bubbly.
- Remove from oven and let it rest for 10 minutes before serving.

Notes
Letting the dish rest after baking helps the layers set for easier serving. Feel free to experiment with different cheeses for a unique flavor.
