Ingredients
  

  • 2 tablespoons unsalted butter
  • 3 cloves garlic minced
  • 2 tablespoons all-purpose flour
  • 2 cups whole milk
  • 1/2 cup heavy cream
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon ground nutmeg optional
  • 2 pounds russet or Yukon gold potatoes peeled and thinly sliced (1/8 inch thick)
  • 1 cup grated parmesan cheese
  • 1 1/2 cups shredded mozzarella cheese
  • Chopped fresh parsley for garnish (optional)

Instructions
 

  • Preheat oven to 375°F (190°C). Grease a 9x13 inch baking dish with butter or nonstick spray.
  • In a saucepan over medium heat, melt the butter. Add garlic and sauté for 1 minute until fragrant.
  • Whisk in the flour and cook for 1 minute to form a roux.
  • Gradually add milk and cream, whisking constantly to prevent lumps. Bring to a simmer.
  • Stir in salt, pepper, and nutmeg if using. Let simmer for 2-3 minutes until slightly thickened. Remove from heat.
  • Arrange half of the sliced potatoes in the prepared baking dish, overlapping slightly.
  • Pour half of the cream sauce over the potatoes. Sprinkle with half of the parmesan and mozzarella.
  • Repeat with remaining potatoes, sauce, and cheeses.
  • Cover with foil and bake for 40 minutes.
  • Remove foil and bake for another 20 minutes until golden and bubbly.
  • Let cool for 10 minutes before serving. Garnish with chopped parsley if desired.

Notes

  • Use a mandoline for evenly thin potato slices that cook uniformly.
  • Don’t skip the simmering step—it helps the sauce thicken before baking.
  • You can substitute half-and-half for the milk and cream combo.
  • Add a pinch of cayenne for subtle heat.
  • For a crispier top, broil the dish for 2-3 minutes after baking.
