Ricotta cheese that is opened can be stored in the refrigerator for one to two weeks. However ricotta that is stored in the freezer can be used for up to three months.
If ricotta cheese is stored in the freezer at a temperature at or below zero degrees Fahrenheit, it can potentially be good indefinitely, though the taste and texture may not be optimal. Ricotta stored in the refrigerator should be tightly covered in its original packaging. In the freezer, ricotta should be tightly sealed in its package. Placing the container inside a freezer bag may help prevent freezer burn.
