Instructions

  1. Preheat the oven to 350 degrees F.
  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.
  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.
  4. Remove from the heat and add the thin potato slices to the leeks. Toss gently to combine thoroughly.
  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.
  6. Bake until the potatoes are very tender, and the cheese has melted and turned a golden brown, about 1 hour.
  7. Let the gratin rest for about 5 minutes before serving.

Notes

  • I highly recommend using the mandoline. The even thickness of the potato slices creates a perfectly cooked gratin.
  • It can be fully assembled and placed in the refrigerator until ready to bake. You can also bake it the day before or a few hours early and reheat it when ready to enjoy.
  • This dish feeds quite a few people, so do not hesitate to cut the recipe in half.
