Parmesan Potato Casserole


I was recently looking for a potato dish to serve as a side which looked impressive and tasted delicious. Enter this Parmesan Potato Casserole which looks seriously cool as thin slices of potato are cooked stacked in a baking dish. Think of a cross between hasselback potatoes and a typical potato casserole.

To make this couldn’t be easier. Start by slicing the potatoes into very thin slices. Toss the potato slices with butter and garlic and season with salt and pepper to taste. Stack the sliced potatoes in a baking dish and bake for an hour until tender. Remove from the oven and sprinkle parmesan cheese and rosemary sprigs over the top. Return to the oven and finish cooking for another 30 minutes.

To make my Parmesan Potato Casserole, you will need the following ingredients:
