Brown beef in a large skillet over medium heat, stirring to break up meat. Drain off fat. Add drained beef to the cooked drained noodles; set aside. In the same skillet, sauté onion, celery, and garlic in melted butter until tender, about 6 to 8 minutes. Add to the beef and noodle mixture. Stir in corn, soup, mushrooms, milk, salt, and pepper. Blend well. Turn mixture into a large casserole or baking dish and sprinkle with the cheese. Bake uncovered at 400° for 25 to 30 minutes or until hot and bubbly.
Serves 6 to 8.
