Potatoes Au Gratin

We wanted to make some potatoes au gratin and chose this recipe for it's simplicity and few ingredients. We probably will not make it this way again. Alona thought it was FAR too oily and greasy, while Nick thought it was just okay.
Overall, not great.

Cooked! 

Ready to cook

Ingredients:

Spray oil for the baking dish
2 1/2 cups heavy cream
1 1/2 teaspoons salt
1/4 teaspoon ground black pepper
3 Yukon Gold potatoes (about 2-1/4 pounds), peeled and sliced very thin
1 cup grated Parmigiano-Reggiano.. we used a mix of cheese 

Directions:

1. Preheat the oven to 350°F. Spray a baking dish with cooking spray.
2. In a mixing bowl, whisk together the cream, salt and pepper.
3. Lay out the potatoes in an overlapping single layer. Add some cheese and cream.
4. Repeat with additional layers. (we only got about 2 layers in our pan - this made it cook better anyways).
5. Place in the oven and bake, uncovered, for about an hour to an hour and half, or until the potatoes are tender when pierced with a knife and golden brown on top.
6. Let the dish settle and cool for about ten minutes before serving.
