Ingredients

For the potatoes:

  • 2 lbs russet or Yukon gold potatoes, thinly sliced
  • 2 tbsp butter
  • 3 cloves garlic, minced
  • 1 tsp salt
  • ½ tsp black pepper

For the cheese sauce:

  • 1 cup heavy cream
  • 1 cup milk
  • 1 ½ cups Gruyere cheese, grated
  • ½ cup parmesan cheese, grated
  • 1 tsp fresh thyme (optional)
  • Pinch of nutmeg (optional)

Instructions

  • Preheat oven to 375°F (190°C) and lightly grease a baking dish.
  • In a saucepan, melt butter over medium heat. Add garlic and sauté until fragrant (about 1 minute).
  • Pour in heavy cream and milk, heating gently without boiling. Stir in salt, pepper, and nutmeg if using.
  • Layer half of the sliced potatoes evenly in the baking dish.
  • Pour half of the cream mixture over the potatoes and sprinkle with half of the Gruyere and parmesan.
  • Repeat with remaining potatoes, cream mixture, and cheeses.
  • Cover with foil and bake for 40 minutes.
  • Remove foil and bake an additional 20–25 minutes, until golden, bubbly, and tender.
  • Let rest for 10 minutes before serving to allow the sauce to thicken.

Notes

Slice potatoes evenly (about 1/8 inch) for consistent cooking.Gruyere provides a nutty, slightly sweet flavor—avoid pre-shredded cheese for best melting.Resting time helps the dish set and improves texture.For extra golden color, broil for 2–3 minutes at the end.
