Toast bread, cut into cubes, set aside.
In a large bowl combine drained sauerkraut, onion, parsley, and caraway seed.
Spoon mixture into a 3-quart rectangular baking dish; spread the mixture evenly.
Layer with half of the cheese, half of the salad dressing, and all of the corned beef. Repeat with the remaining salad dressing and cheese.
Sprinkle bread cubes over the top of the casserole.
Bake covered in a 375° oven about 3 minutes or until heated through. Uncover and bake 5-10 more minutes until bread cubes are browned.
