1/4 cup butter or margarine 
2 medium onions, chopped 
4 celery ribs, chopped 
2 (8-ounce) cans sliced water chestnuts, drained 
5 cups chopped cooked chicken 
4 cups cups (1 pound) shedded Cheddar cheese, divided 
2 (10 3/4-ounce) cans cream of mushroom soup, undiluted 
2 (8-ounce) containers sour cream 
1 cup milk 
1/2 teaspoon salt 
1/2 teaspoon pepper

Preheat oven to 350 degrees F.  Prepare rice according to package directions; set aside. 
Melt butter in a large skillet over medium heat; add onion, celery and water chestnuts. Saute 10 minutes or until tender. Stir in rice, chicken, 3 cups cheese, and next 5 ingredients; spoon mixture into a lightly greased 15- x 10-inch baking dish or a 4-quart casserole. Top with breadcrumbs if desired. Bake casserole at 350°F for 30 minutes. Sprinkle with remaining 1 cup cheese, and bake 5 more minutes.
