Instructions
 

Preparation

  • Preheat your oven to 180°C (350°F). Grease a large baking dish with butter.
  • Peel the potatoes and slice them thinly using a mandoline or a sharp knife. Set aside.

Making the sauce

  • In a mixing bowl, whisk together the heavy cream, milk, garlic, salt, pepper, and nutmeg until well combined.
  • Add the grated Parmesan cheese into the mixture and stir to blend.

Assembling the gratin

  • Layer half of the sliced potatoes evenly in the prepared baking dish.
  • Pour half of the cream mixture over the potatoes, ensuring even coverage.
  • Repeat with the remaining potatoes and pour the rest of the cream mixture over the top.

Baking the gratin

  • Cover the baking dish with foil and bake in the preheated oven for 40 minutes.
  • Remove the foil, sprinkle the extra grated Parmesan cheese on top, and drizzle with melted butter.
  • Return to the oven and bake uncovered for an additional 20 minutes, or until the top is golden brown and bubbling.

Serving

  • Allow the gratin to rest for 5–10 minutes before serving. Enjoy as a side dish to your favorite main course.

Tips and Variations

For an extra crispy topping, broil the gratin for 2–3 minutes at the end of the baking time. You can also add breadcrumbs mixed with Parmesan for a crunchy twist.
