This easy potato au gratin is the perfect side dish. Tender layered potatoes in a creamy garlic parmesan sauce. Not only is this quick to whip up, but once assembled simply toss in the oven until done! This can be made a few hours in advance and baked once ready, making it perfect for holidays or dinner parties.




This potato au gratin can be made in any oval or rectangular casserole dish or any cast iron skillet.
Tools I used for this recipe:
- Oval Baking Dish – both functional and modern!
- Handheld Mandolin – perfect for getting even slices, this mandolin has a rubber handle for good grip and a safety guard. Plus it takes up very little space and you can change the thickness as desired.
- Stainless Steel Sauce Pan – the perfect size pan for warming up the cream mixture!
