Preheat the oven to 375°F (190°C).

Grease a baking dish with butter.

Thinly slice the Yukon Gold potatoes to about 1/8 inch thick.

In a skillet over medium heat, melt butter and sauté minced garlic until fragrant.

In a bowl, mix heavy cream with salt, pepper, and half of the grated cheddar cheese.

Layer half of the sliced potatoes in the baking dish, pour half of the cream mixture over them, then repeat. Top with remaining cheese.

Cover with foil and bake for 45 minutes; remove foil and bake for another 15-20 minutes until golden brown.
