Preheat the oven to 400 degrees, and prepare about an eight-inch baking dish (preferably one with a lid or you can cover it with aluminum foil) by spraying it with cooking spray.
Add all of the ingredients (leave out a bit of parmesan to sprinkle over the top of the dish) to the bag, and shake to coat the potatoes as evenly as possible.
Arrange the slices so they just slightly overlap in a spiral pattern in your baking dish. Sprinkle the remaining parmesan cheese over the top.
Bake, covered, for 30 minutes, checking every 5 minutes after that to see if your potatoes are fork tender.
When they are done, remove from the oven and serve.
