  • Casserole dish



  • Preheat oven to 375 degrees.
  • Peel and slice the potatoes. Place the slices of potatoes in a bowl filled with cold water as you cut them so they don't turn brown.
  • Rub the two halves of garlic on the sides and bottom of a 2.5 liter or 3 quart casserole dish. Spread butter along sides and bottom of the dish.
  • Heat the heavy cream and milk on medium heat until it comes to a simmer.
  • Drain the water from the sliced potatoes.
  • Layer half of the sliced potatoes, half of the heated cream mixture, and half of the cheese, then repeat.
  • Bake until potatoes are soft and golden brown on top, about 50-55 minutes.
