  • 1 tsp salt
  • 0.5 tsp black pepper

  • Baking dish (9x13 inch)
  • Large bowl

Method
 

Preparation
  1. Preheat your oven to 375°F (190°C) and lightly grease a 9x13 inch baking dish.
  2. In a large bowl, combine the thinly sliced potatoes, heavy cream, minced garlic, salt, and black pepper, tossing until the potatoes are evenly coated.
Assembly and Baking
  1. Spread half of the potato mixture evenly in the prepared baking dish, then sprinkle with half of the Gruyere and Parmesan cheeses.
  2. Add the remaining potato mixture and top with the rest of the cheeses, ensuring an even layer.
  3. Bake for 20 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
Finishing Touches
  1. Remove from the oven and let it rest for a few minutes before serving.
  2. Garnish with fresh parsley or sliced green onions, if desired, then serve warm.

Notes

For extra crispiness, you can broil the top for the last 2-3 minutes of baking, watching carefully to prevent burning. This dish pairs well with roasted meats or as a standalone comfort food.
