  • 5 large potatoes thinly sliced
  • 1 ½ cups heavy cream
  • 2 cloves garlic chopped
  • 2 tbsp butter
  • 1/8 tsp salt
  • 1/8 tsp ground black pepper
  • 1 cup gruyere cheese (cheddar will work too) grated


  • Prepare by greasing baking dish with butter and preheat oven to 350°F/180°C.
  • Peel the potatoes and slice them 1/8" x 3 mm thick or as thin as you can possibly go. Or use a slicer for convenience!
  • Soak potato slices in water to prevent oxidation or turning brown.
  • Heat saucepan over medium heat then pour in the heavy cream, garlic, butter, salt, and pepper. Let cook until butter melts. Remove from heat and set aside.
  • Drain water from the potatoes and take your prepared greased baking dish.
  • Pour a small amount of the cream mixture, just enough to cover the bottom of the dish. Spread some of the potatoes in a baking dish to make a first layer.  Then pour over some of the cream mixture again then repeat the process until you finish all potato slices and cream mixture.
  • Sprinkle cheese on top of the potatoes and spread evenly. Cover with aluminum foil and bake for 1 hour and 30 minutes. NOTE:At 1 hour and 15 minutes, check the potatoes if tender and remove foil. turn on fan/broil setting of oven to give the top a golden brown crust.
  • Remove from oven and serve as a side or on it's own! Bon Appetit!
