When it comes to pesto, a little goes a long way. The blend of garlic, basil, and pine nuts packs a burst of flavor with every small scoop added to creamy pesto pasta dishes, well-seasoned sandwiches, and more. Most recipes don't call for a very large helping of pesto, leaving the rest of the unsealed jar to wait until the next time it's needed. Unfortunately, pesto does not have a particularly long shelf life after it has been opened.
A sealed jar of pesto will typically last between four and six weeksin your pantry, with the exact "best by" date depending on the brand and type of pesto. But once you crack open a jar of the store-bought sauce, it's best to only keep it around for up to five days in the fridge. While you won't see any unappetizing mold build-up for at least a few weeks, you may notice a difference in flavor after just 72 hours. Luckily, there are ways to elongate its shelf life and prevent tossing yet another half-full jar of tasty pesto before its time runs out.
