How long can I safely store an opened jar of pasta sauce in the refrigerator? How about the freezer?

Tomato Sauces can remain in the refrigerator for about 10 days. Our Cheese based Sauces can remain in the refrigerator for about 3 days.
You may freeze unused portions of the Bertolli tomato sauces in a freezer safe container for up to 3 months. For the cheese based sauces, freezing is not recommended.
