Ingredients
  

Main Ingredients
  • 2 lbs potatoes thinly sliced
  • 2 cups heavy cream
  • 1 tsp Garlic powder
  • 1 tsp salt
  • 0.5 tsp black pepper
  • 2 cups Gruyère cheese shredded
For Topping
  • 0.5 cup Parmesan cheese grated

Equipment

  • Oven
  • Baking dish (9x13 inch)
  • Mandoline or sharp knife
  • Large bowl
  • Aluminum foil

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  2. Thinly slice the potatoes using a mandoline or sharp knife for even cooking.
Assembly and Baking
  1. In a large bowl, combine heavy cream, garlic powder, salt, and black pepper.
  2. Arrange a layer of sliced potatoes in the prepared baking dish, slightly overlapping.
  3. Sprinkle a portion of shredded Gruyère cheese over the potatoes.
  4. Pour some of the cream mixture over the potatoes and cheese.
  5. Repeat the layers until all ingredients are used, ending with a layer of potatoes.
  6. Cover the baking dish with aluminum foil and bake for 30 minutes.
  7. Remove the foil, sprinkle with grated Parmesan cheese, and bake for another 15-20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
Serving
  1. Let the au gratin potatoes rest for 5-10 minutes before serving to allow the layers to set.

Notes

For extra flavor, infuse the cream with a bay leaf and a few sprigs of thyme before pouring over the potatoes. To ensure even cooking, slice your potatoes as uniformly as possible. If you don't have Gruyère, cheddar or a blend of melting cheeses works well too.
