My neighbor served this for dinner, and everyone couldn't stop talking about it

Pork chops and potatoes get a gourmet makeover in this casserole. A base of cream-infused potatoes and onions is topped with Dijon mustard-coated pork chops and a Gruyère cheese and breadcrumb topping. Bake for just 30 minutes, and the recipe below will reveal itself to be something truly special.
If alpine Gruyère isn't your favorite, other cheeses can certainly take its place. Try Swiss cheese for something a bit more mellow, or blue cheese for something even funkier. Add your favorite herbs and spices along with — or instead of — the mustard to give this recipe a unique flair.
