How Long Does Sun-Dried Tomato Pesto Last?
How long does sun-dried tomato pesto last in the pantry?
Sun-dried tomato pesto lasts about 12–24 months in the pantry when kept in an airtight container.
Sun-dried tomato pesto is a flavorful staple, blending concentrated tomato notes with herbs and oil. Because of its high oil content and the low moisture level of sun-dried tomatoes, it is quite stable for storage. However, environmental factors like heat, light, and oxygen can eventually cause the fats to go rancid or the flavors to dull. Keeping your jar sealed and stored in a cool, dark space ensures that this savory condiment remains a delicious addition to your pantry for many months. Always monitor the oil quality, as oxidation is the primary factor affecting its longevity.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long can I keep sun-dried tomato pesto in my pantry?
Sun-dried tomato pesto lasts about 12–24 months in the pantry if stored in an airtight container in a cool, dark place.
Can I store sun-dried tomato pesto in the refrigerator?
Yes. Refrigeration extends quality, though be aware that the oil may solidify and become thicker or harder to spread.
Does opening the jar affect how long the pesto lasts?
Yes. Exposure to air and light accelerates oxidation. Always seal the lid tightly immediately after use to maximize shelf life.
Why does my pesto smell strange after several months?
A sharp or heavy scent usually indicates rancid oil, which occurs when the fats in the pesto oxidize due to age or air exposure.
Can I freeze sun-dried tomato pesto?
You can freeze it, but be mindful that moisture changes during the freezing and thawing process may slightly alter the texture of the oil.
Keep that pesto in a cool, dark spot and it will stay delicious for many months of snacking.
