Preheat the oven to 400 degrees F.
Lightly grease a 1 1/2-quart baking dish with the butter and set aside. Place the cream in a large saucepan and bring to a simmer over medium-high heat. Add the salt and pepper, and stir well. Add the potatoes, adding more cream, if necessary, to completely cover the potatoes. Lower the heat to medium-low and simmer until the potatoes are barely fork tender, about 10 to 12 minutes. Remove from the heat.
With a large spoon, transfer 1/3 of the potatoes with some of the cream to the prepared dish, forming an even layer on the bottom. Top with 1/3 of the cheese, and continue layering the potatoes and cheese, ending with cheese on top. Place on a baking sheet and bake until golden brown and bubbly, about 30 minutes.
Remove from the oven and let sit for 5 minutes. Serve hot.
