Preheat: Preheat your oven to 180°C (356°F). Grease a baking dish with butter to prevent sticking.

Wash and Slice: Wash the potatoes and slice them thinly, about 1/8 inch thick. You can use a mandoline slicer for consistent thickness.

First Layer: Arrange a layer of potato slices at the bottom of the greased baking dish. Overlap them slightly to ensure no gaps.

Garlic and Seasonings: Sprinkle some of the minced garlic over the potatoes, then season with salt and black pepper.

Mix Liquids: Mix the milk and cream together and pour half of this mixture over the first layer of potatoes.

Cheese Layer: Sprinkle a generous amount of grated cheese over the top, then repeat the layering process—potatoes, garlic, salt, pepper, and the milk/cream mixture, finishing with a layer of cheese on top.

Cover and Bake: Cover the dish with aluminum foil and place it in the preheated oven. Bake for about 40 minutes.

Uncover and Finish: After 40 minutes, remove the foil and bake for another 20-30 minutes or until the top is golden brown and bubbly, and the potatoes are tender.

Rest and Serve: Let the dish sit for a few minutes after baking to settle the layers and flavors. Then, serve hot.
