Stuffing can keep around 2 weeks if stored properly at room temperature (60°f). Stuffing can also keep around 3 months if frozen properly (-18°f). For best results freeze stuffing overnight before storing so as not freeze any moisture into your stuffings during freezing process. . If you are going on vacation but don't know when you will return home we suggest freezing leftovers until returning home because they will last much longer than refrigerated leftovers!
