| Preheat oven to 375. Put chicken, celery, water chestnuts, mushrooms, soup, mayo and sour cream in a large bowl and stir until well combined. Put chicken mixture into a 9 x 13 baking dish that has been lightly coated with cooking spray and bake for 25 to 30 minutes or until celery is crisp-tender. Remove casserole from oven. Unroll croissant dough into flat pieces and cover chicken mixture with the slices of dough. Using a pastry brush, lightly brush butter on the dough. Bake for 10 - 12 minutes or until croissant topping is turning golden brown. Remove casserole from oven and sprinkle on parmesan cheese. Bake for one to two more minutes. Let stand 5 minutes before serving. |
