  • 2 pounds russet or Yukon Gold potatoes, peeled and thinly sliced (about 1/8 inch thick)
  • 2 cups heavy cream
  • 1 cup whole milk
  • 2 cloves garlic, minced
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon ground nutmeg
  • 2 cups shredded Gruyere cheese (or a mix of Gruyere and Parmesan)
  • 2 tablespoons unsalted butter, cut into small pieces
  • Fresh thyme leaves (optional, for garnish)


  1. Prepare the Oven and Baking Dish:
    • Preheat your oven to 375°F (190°C).
    • Grease a 9×13-inch baking dish or a similar-sized gratin dish with butter.
  2. Prepare the Cream Mixture:
    • In a medium saucepan, combine the heavy cream, milk, minced garlic, salt, black pepper, and ground nutmeg.
    • Heat over medium heat until the mixture begins to simmer. Remove from heat and set aside.
  3. Assemble the Gratin:
    • Arrange a layer of sliced potatoes in the bottom of the prepared baking dish, slightly overlapping each slice.
    • Pour about 1/3 of the cream mixture over the potatoes, then sprinkle with 1/3 of the shredded cheese.
    • Repeat the layers twice more, ending with the remaining cheese on top. Dot the top layer with the small pieces of butter.
  4. Bake the Gratin:
    • Cover the baking dish with aluminum foil and bake in the preheated oven for 45 minutes.
    • Remove the foil and continue baking for an additional 30-35 minutes, or until the top is golden brown and the potatoes are tender when pierced with a fork.
  5. Garnish and Serve:
    • Remove the gratin from the oven and let it sit for about 10 minutes before serving. This allows the dish to set and makes it easier to slice.
    • Garnish with fresh thyme leaves if desired.
    • Serve warm as a side dish to your favorite main courses.
