Preheat oven to 400ºF. Slice bread into ½ inch thick slices (yields about 14). Place on a baking sheet and put into the 400º oven. Bake for 15 minutes. Remove from oven and turn. Place back in the oven and bake for an additional 10 minutes. This will toast the bread. Allow bread to cool. Cube or crumble bread into a large mixing bowl and set aside. Reduce the oven temperature to 350ºF. In a large skillet, brown the sausage, salt, pepper, poultry seasoning, and onions over medium heat. Add the celery, sage, rosemary, and thyme; continue cooking and stirring for another 3 minutes. Pour sausage mixture over bread crumbs. Add the chopped apple, cranberries, parsley, and turkey stock. Mix well and place in a greased 9X13 baking dish. Cover with foil and bake at 350ºF for 20 minutes. Remove the foil and bake an additional 10 minutes.
