ingredients

  • 3 tablespoons unsalted butter
  • 2 sliced leeks
  • 3 chopped garlic cloves
  • 1 tablespoons chopped fresh thyme
  • 2 cups heavy cream
  • 3 russet potatoes
  • 1 cup heavy cream
  • Gruyere cheese
  • salt and pepper

Method

  • Step 1

    Preheat the oven to 350 degrees F.

  • Step 2

    Melt the butter in a large skillet or sauté pan over medium-low heat. Once melted, add the leeks, garlic and thyme and season with salt and pepper. Cook by stirring occasionally and until the leeks are soft about 8 to 10 minutes.

  • Step 3

    Add the cream and bring to a boil. Season with salt and pepper, reduce the heat to a simmer, and let the leeks and cream cook for another 4 minutes

  • Step 4

    Remove from the heat and add the thin potato slices to the leeks. Toss gently to combine thoroughly.

  • Step 5

    In a gratin dish, layer half of the potato-leek mixture and sprinkle with half of the gruyere cheese. Cover with the remaining half of the potatoes and top with the remaining gruyere cheese

  • Step 6

    Bake until the potatoes are very tender, and the cheese has melted and turned a golden brown, about 1 hour.

  • Step 7

    Let the gratin rest for about 5 minutes before serving.
