Spaghetti Sauce Shelf Life

What is the Shelf Life of Spaghetti Sauce

 

The store-bought Spaghetti Sauce comes with a best-by date. But, you must not confuse it with the expiry date. The best-by date is just the estimated time for how long the sauce will be best in quality. After the best-by date, the quality starts degrading.

For an unopened bottle of Spaghetti Sauce, it is safe to use the sauce for an extra three-five months after the best-by date, provided that it is stored properly in the fridge or pantry. It must not be exposed to direct sunlight or any heat sources.

How Long Does Spaghetti Sauce Last Unopened?

The opened Spaghetti Sauce’s shelf life is one week, especially when stored in a fridge after opening. After that, it starts losing its quality and taste. But, the sauce is safe for consumption even after two weeks of refrigeration. The taste may differ.

The homemade Spaghetti Sauce tends to last for three-four days, even after proper refrigeration. So, it would be best if you freeze the homemade Spaghetti Sauce to extend its shelf life.

For open Spaghetti Sauce, the best place is a fridge. After opening the bottle, store it in a refrigerator to extend its shelf life for seven-ten days.

 

Shelf Stable

Since Spaghetti Sauce is not a shelf-stable sauce, it must be refrigerated once opened. However, room temperature is fine for the storage of sealed and unopened bottles. The best place is the kitchen cabinet or the pantry.

Ensure to store it at a place that is away from direct sources of heat and sunlight. It must be kept in dry, cool, and dark places.

 

Is it OK to use expired spaghetti sauce?
