Ingredients
  

  • 1 lb Yukon Gold potatoes about 7 large
  • 1 medium onion, sliced into rings (optional)
  • Salt and ground black pepper to taste
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour can use gluten-free flour
  • ½ teaspoon salt
  • 2 cups whole milk can use 2%
  • 1 cup shredded fontina cheese more for topping
  • ½ cup shredded Gruyère cheese or mild white cheddar, more for topping
  • ½ cup shredded Parmigiano cheese more for topping
  • Fresh thyme, rosemary, or fresh parsley for garnish

Instructions
 

  • Preheat oven to 375°F (190°C). Grease a 2.5-quart baking dish with butter or cooking spray.
  • Slice potatoes into ⅛-inch thick slices and layer them upright in the prepared baking dish. Season with salt and pepper.
  • In a saucepan, melt butter, then whisk in flour. Gradually add milk, stirring constantly until the mixture thickens (about 10 minutes).
  • Remove from heat and stir in the cheeses until melted and smooth.
  • Pour the cheese sauce over the potatoes and cover with foil (sprayed with cooking spray).
  • Bake for 60 minutes, then remove foil and top with more cheese. Bake for another 15 minutes or until golden and bubbly.
  • Let cool for 15 minutes before serving. Garnish with fresh herbs.

Notes

For extra flavor, add minced garlic to the sauce. To make it heartier, consider layering in cooked bacon or sausage between the potato slices.
