Step 1

Preheat the oven to 350° F. Combine the cream, thyme, pepper, and salt in a medium sized bowl.

Step 2

Grease a 2.5 - 3 qt baking dish. Butter is preferred, but I won't tell anyone if you use cooking spray.Place a layer of 1/4 of the sliced potatoes in the dish, slightly overlapping each slice. It's fine if you have to overlap some pieces entirely with others.

Step 3

Sprinkle 1/4 of the parmesan on top of the potatoes and pour 1/4 of the cream mixture over it all.

Step 4

Repeat steps two and three until no ingredients are left. You should end with a sprinkle of cheese and pouring over of cream mixture.

Step 5

Bake for 65 to 70 minutes, or until potatoes in the center are tender and top is browned.
