How to Store Pasta Sauce

Unopened jars of pasta sauce should be stored at room temperature in a cupboard or pantry. If you prefer, you may also store them in the refrigerator. Jars of pasta sauce that have been opened can be stored for 3-5 days in the refrigerator. If you don’t use the sauce during that time frame but want to save it for future use, you can transfer it to a freezer-safe container and store it in the freezer for up to 3 months.
