How Long Does Pesto Last? Unlock the Secrets of Pesto

Pesto is a delicious and versatile condiment that can add flavor to almost any meal. But how long does it last? Unopened store-bought pesto, sold unrefrigerated, has a shelf life of 2 – 3 months beyond its best-by date. If it’s sold refrigerated, it will last for 1 – 2 weeks beyond its use-by date. Once opened, unrefrigerated pesto lasts for 4 days to 2 weeks, while refrigerated pesto can be consumed within 4 – 7 days. Homemade pesto has a shorter shelf life of 4 days. If you have leftover pesto that you don’t think you’ll be able to finish before its expiration date, freezing is an option. To freeze leftover pesto, spoon the sauce into an airtight container and place in the freezer for up to 6 months. When ready to use, thaw the container in the refrigerator overnight before serving.

Unrefrigerated Pesto: Shelf Life and Storage Tips

Pesto is a versatile and delicious condiment used in many dishes. It’s no wonder why it has become so popular! But, with its long shelf life when unrefrigerated, it’s important to understand how to properly store pesto and ensure it stays fresh for as long as possible.

Filippo Berio suggests storing their pesto up to two weeks after opening, while Mantova recommends using theirs within three days. This difference in shelf life is due to the various preservatives used by different brands.

It’s important to read the label of your chosen brand of pesto to determine how long it will stay fresh after opening. If there are no specifics on the label, play it safe and use your pesto within 3-4 days to be sure.

By understanding proper storage techniques for unrefrigerated pesto, you can enjoy this delicious condiment for much longer than expected!
