The world of condiments and sauces is vast and varied, with countless options to enhance the flavor of our meals. Among these, pesto stands out as a particularly popular and versatile choice, with its rich, herby flavor and vibrant green color. But have you ever stopped to think about how long pesto lasts in the refrigerator? It’s a question that’s often overlooked, yet it’s crucial to ensure that your pesto stays fresh and safe to eat.
Understanding the Shelf Life of Pesto

These ingredients have different shelf lives, which can affect the overall shelf life of the pesto. For example, basil is a delicate herb that’s prone to spoilage, while olive oil is a stable fat that can last for months.
