Freeze unbaked casserole up to 3 months. When ready to serve, bake, covered, in 400ºF oven 1 hour 15 min. to 1 hour 20 min. or until casserole is heated through and cheese is melted, uncovering after 1 hour. (No need to thaw first.) Let stand 5 min. before cutting to serve. Or, to shorten the baking time, thaw casserole in refrigerator overnight before baking as directed, decreasing the baking time to 45 min. Frozen casserole can be removed from baking dish, then wrapped tightly in plastic wrap and foil before returning to the freezer. When ready to serve, remove foil and plastic wrap and return to baking dish. Cover with foil and bake as directed.
