Prepare potatoes according to package directions. Beat in cheese, sour cream, yolks, chives and celery salt. Beat whites until stiff peaks form; fold whites and parsley into potatoes.
Turn into a 2 qt. casserole and dot with butter. Bake at 350 degrees F until lightly browned, about 1 hour. Makes 6-8 servings.
