Marinara sauce is a popular staple in many kitchens, and its shelf life depends on whether it's opened or unopened. Unopened store-bought marinara sauce can typically last for up to 12 to 18 months past the printed expiration date if stored in a cool, dry pantry. This extended shelf life is due to preservatives and the vacuum-sealed packaging, which keep the sauce fresh for an extended period. Once the marinara sauce is opened, its shelf life decreases significantly. In the refrigerator, an opened jar of marinara sauce can generally last for about 5 to 7 days. It's essential to ensure the jar is tightly sealed to prevent any air or contaminants from spoiling the sauce. Homemade marinara sauce, on the other hand, lacks the preservatives found in store-bought versions, which means it typically lasts 3 to 5 days in the refrigerator. To maximize the freshness of marinara sauce, always use a clean spoon when serving to avoid introducing bacteria. If there's any doubt about the sauce's freshness, checking for signs of spoilage such as an off smell, discoloration, or mold is vital. Freezing is an excellent way to extend the shelf life of marinara sauce, whether homemade or store-bought, allowing it to last for up to six months when properly stored in an airtight container.

How to store leftover marinara

It's important to handle the storage of your marinara sauce in the fridge with care. First and foremost, make sure to keep your sauce in a sealed container. Storing food in an open container can cause it to dry out, resulting in an undesirable texture. It can also allow other odors from the fridge to mix with your sauce, which isn't very appetizing. Furthermore, ensure that your marinara is kept in a refrigerator set below 40 degrees Fahrenheit, and avoid placing it in areas like the door that are subject to temperature changes. If your marinara was originally in a tin can, be sure to transfer any leftovers to a different container to prevent any negative effects. If you don't plan to consume the leftover sauce within five to seven days, freezing it is a great option. Your marinara sauce can remain good for up to six months in the freezer.

No matter how you store your leftover marinara sauce, it's essential to watch for signs of spoilage or contamination. Here are a few indicators to help you avoid using spoiled sauce. First, if the color of your marinara has changed or it has developed a sour smell, it's best to discard the jar. Additionally, if you notice any mold on or inside the sauce, it should be thrown away right away, as mold toxins can be harmful. When in doubt, it's safer to throw the sauce out rather than take any risks.

It's also worth mentioning that even unopened jars of marinara can go bad. Canned marinara, in particular, is at risk for botulism—a serious foodborne illness—especially if the can is damaged. Therefore, any cans with significant bulges, holes, or dents (especially along the seams) should be discarded immediately for safety.
