Potato Gratin Ingredients

  • 2 lbs Russet potatoes, thinly sliced
  • 2 cups heavy cream
  • 1 cup whole milk
  • 2 cloves garlic, minced
  • 1 teaspoon fresh thyme, chopped
  • 1 ½ cups Gruyère cheese, grated
  • ½ cup Parmesan cheese, grated
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 tablespoon butter (for greasing the dish)
  • Optional: ½ cup panko breadcrumbs mixed with 2 tablespoons Parmesan cheese for topping

Instructions
 

  • Preheat the oven to 375°F (190°C) and butter a large baking dish.
  • In a saucepan, combine heavy cream, whole milk, garlic, thyme, salt, and pepper. Heat over medium-low heat until warmed through, about 5 minutes.
  • Layer the potatoes in the prepared baking dish, overlapping slightly. Pour a small amount of the cream mixture over the potatoes and sprinkle with Gruyère and Parmesan cheese. Repeat layers until all ingredients are used.
  • Cover the dish with foil and bake for 40 minutes.
  • Remove the foil and sprinkle the optional breadcrumb mixture on top (if using). Return the dish to the oven and bake uncovered for an additional 20-25 minutes, or until the top is golden and bubbly.
  • Let the gratin rest for 10 minutes before serving.

Notes

Use a mandoline slicer for even, thin potato slices to ensure uniform cooking. For extra richness, you can substitute some of the milk with more heavy cream.
