Partially thaw the hash browns so they mix in and bake evenly. Use already-cooked chicken (rotisserie is easy). Toss the cornflakes well with the butter for an even, crisp topping. Let the casserole rest 10 minutes after baking so it sets and serves neatly. Tent with foil if the topping browns before the casserole is heated through. Make-ahead: assemble without the topping and refrigerate, then add the topping and bake. Keeps 3 to 4 days refrigerated; freezes up to 3 months (refresh the topping when reheating).
