Directions:

1. Preheat oven to 375°F. Slice the potatoes on a mandolin or box grater into 1⁄4-inch thick slices.
2. Mix together heavy cream, salt, pepper, garlic, and 1 cup of Parmesan cheese in a large mixing bowl. Add the Boursin cheese and mix well. Add the potatoes and toss to combine.
3. Prepare a shallow 9 x 9 casserole dish with pan spray. Place the potato mixture in the dish and cover with foil. Bake in the oven until potatoes are tender – approximately 40 minutes.
4. Remove foil, top with remaining 1⁄4 cup of Parmesan cheese and cook until golden brown on top – approximately 15 more minutes. Let sit 15 minutes before serving.
