  • How long does pesto last once opened? The precise answer depends to a large extent on storage conditions  to maximize the shelf life of opened pesto, keep it refrigerated and tightly covered.
  • How long does pesto that was sold unrefrigerated last in the fridge once opened? Pesto that was sold unrefrigerated will keep for about 1 to 2 weeks in the fridge after opening, assuming continuous refrigeration.
  • To further extend the shelf life of opened pesto, freeze it: to freeze pesto, place inside covered airtight containers or heavy-duty freezer bags.
  • How long does pesto last in the freezer? Properly stored, pesto will maintain best quality in the freezer for about 4 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only  pesto that has been kept constantly frozen at 0° F will keep safe indefinitely.
  • How can you tell if opened pesto is bad or spoiled? The best way is to smell and look at the pesto: if the pesto develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
