What Determines the Shelf Life of Pesto?

Before we dive into the specifics, it's important to understand that the shelf life of pesto can vary depending on whether it's store-bought or homemade.

Store-Bought vs Homemade Pesto

Store-bought pesto usually comes in two forms: refrigerated and unrefrigerated. The unrefrigerated pesto sold in jars tends to have a longer shelf life, lasting up to two weeks after opening. On the other hand, refrigerated pesto, whether it's in jars or containers, has a shorter storage time of a few weeks and should be consumed within a few days of opening.

Homemade pesto, as delightful as it may be, has a slightly shorter lifespan. It can last for about 3 to 4 days in the fridge. But hey, that's plenty of time to enjoy it on your favorite dishes!

How Long Does Opened Pesto Last?

Now that we know the general shelf life of pesto, let's take a closer look at how long it lasts once it's been opened.

Storing Jarred Pesto After Opening

With jarred pesto, whether it's store-bought or homemade, it's crucial to keep it tightly sealed after opening. For unrefrigerated pesto, like the ones sold in jars, it should be refrigerated once opened and consumed within the recommended time frame mentioned earlier. Remember, we don't want to let any air in there that could spoil our beloved pesto!
