Preheat the Oven: Heat your oven to 150°C (300°F). This low temperature allows the potatoes to cook through without burning.

Prepare the Baking Dish: Use butter to grease a baking dish thoroughly. This not only prevents sticking but also adds flavor.

Arrange the Potatoes: Layer the thinly sliced potatoes in the greased baking dish. The thinner the slices, the quicker and more evenly they will cook.

Make the Cream Sauce: In a saucepan, combine the cream, chopped garlic, salt, and black pepper. Heat the mixture over medium heat until it just begins to simmer. Be careful not to let it boil over.

Stir well to ensure the garlic is evenly distributed and the seasonings are well mixed.

Bake the Potatoes: Pour the hot cream mixture over the arranged potatoes, making sure it seeps into every layer.

Place the dish in the preheated oven and bake for about 30 minutes. During this time, the cream will thicken and begin to absorb into the potatoes.

Add the Cheese: Remove the dish from the oven and evenly sprinkle the mozzarella cheese over the top of the potatoes.

Return the dish to the oven and continue to bake for an additional 15-20 minutes, or until the cheese is fully melted and starts to turn golden brown.

Garnish and Serve: Once baked, remove the dish from the oven and let it cool slightly for a few minutes.

If desired, garnish with freshly chopped parsley for a touch of color and freshness.

Serve warm as a perfect accompaniment to meats, poultry, or even as a standalone dish with a side salad.
