  • 2 cups (about 220g) shredded Gruyère or mozzarella cheese

Instructions

  1. Preheat oven to 375°F (190°C). Roast the garlic by cutting off the top, drizzling with olive oil, sprinkling with salt, and wrapping in foil.
  2. Grease a 9×13-inch baking dish with butter.

  4. Layer the potato slices upright in the baking dish.
  5. In a saucepan over medium heat, combine cream, milk, butter, half of the parmesan cheese, thyme, nutmeg, salt, and pepper; stir until melted and combined.
  6. Squeeze roasted garlic cloves into a bowl, mash into a paste, and mix into the cream mixture.
  7. Pour the creamy mixture over the potatoes evenly; cover with foil.
  8. Bake for about 40 minutes until potatoes are tender.
  9. Remove foil, add remaining cheese on top, and bake uncovered for another 30 minutes until golden brown.
  10. Allow to cool slightly before serving; garnish with fresh chives.
