Brown pork chops in oil. Increase heat and add wine, scraping up browned bits. Place pork chops in baking pan; pour in pan juices. Top with potatoes, sliced onion, 1 teaspoon thyme, and 3 tablespoons of the parsley. Pour beef broth around sides. Cover tightly with foil and bake at 350° for 30 to 40 minutes. Take out of the oven and sprinkle with buttered bread crumbs and remaining parsley and a little more thyme.
Put back in oven and bake for about 5 to 10 minutes longer, until crumbs are lightly browned.
