This simple and warming baked recipe is much more than the sum of its parts. Simple ingredients combine to make a deeply satisfying dish; the potatoes and cabbage cook along with a bit of cream and then are topped with cheese to make a rich and creamy side dish. Plus, if you use an oven-safe pan from the start it becomes a one-pan meal. Use the optional bacon or pancetta for extra flavor, substitute in sausage for a heartier dish, or leave out the meat for a delicious vegetarian dinner.
