Fresh pesto is a delicious and versatile sauce that can elevate any dish with its vibrant flavors. But how long can you keep it in the refrigerator before it starts to lose its freshness? Let’s delve into the shelf life of fresh pesto and how to make the most of this culinary gem in your kitchen.

Fresh pesto is a versatile and delicious sauce that can add a burst of flavor to a variety of dishes. Whether you use it in pasta, sandwiches, or salads, pesto is a crowd-pleaser. But how long does fresh pesto last in the refrigerator? The answer depends on a few key factors.

Typically, fresh pesto can last in the refrigerator for about 4-5 days. To help extend its shelf life, it is important to store pesto properly. Make sure to keep it in an airtight container to prevent oxidation and maintain freshness. Adding a thin layer of olive oil on the surface can create a barrier that helps preserve the sauce.

Additionally, it’s best to store pesto away from heat and light, as these elements can cause it to spoil more quickly. Keep it in the back of the refrigerator, where it is cooler and darker, to maintain its flavor for longer.

If you want to further prolong the shelf life of your pesto, consider freezing it. Simply transfer the pesto to an ice cube tray, freeze until solid, and then transfer the pesto cubes to a freezer-safe bag or container. You can store frozen pesto for up to 3 months and thaw it when ready to use.

By following these tips and tricks, you can enjoy fresh pesto for longer periods of time. So next time you whip up a batch of this flavorful sauce, remember to store it correctly to keep it tasting delicious.
