Potatoes and Ham Au Gratin

Layered with potatoes, onion, ham, and cheese sauce, this au gratin dish is great as a side for a holiday dinner, but also makes a hearty main casserole dish. The potatoes come out tender and cheesy, and the top crusted with a delicious breadcrumb mixture. Prepare ahead of time, because this dish takes over an hour to bake (but it is soo worth it!).
