Method

Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 180°C (350°F).

  2. 2

    Prepare the Potatoes

    Peel and slice the potatoes thinly, ideally using a mandoline for uniformity.

  3. 3

    Make the Cream Mixture

    In a saucepan, combine the heavy cream, whole milk, minced garlic, salt, and black pepper. Heat gently until warm but not boiling.

  4. 4

    Layer the Ingredients

    In a greased baking dish, layer half of the sliced potatoes, then drizzle with half of the cream mixture. Sprinkle half of the Gruyère and Parmesan cheeses. Repeat with the remaining potatoes and cream mixture. Top with the remaining cheeses.

Baking

  1. 5

    Bake the Gratin

    Cover the dish with foil and bake for 45 minutes. Then remove the foil and bake for an additional 15-20 minutes, or until golden and bubbling.

  2. 6

    Finish with Truffle Oil

    Once baked, remove from the oven and drizzle with truffle oil and shave fresh truffles on top before serving.
