Does Pesto Go Bad?

Pesto is typically eaten with pasta but it can also be used as a spread for sandwiches or on top of vegetables. One of the things you may run into is whether pesto is bad or not.

Does Pesto Go Bad?

Pesto is a sauce made from basil, pine nuts, and Parmesan, and can last up to three days in the refrigerator.

Pesto can go bad if you let it sit out for too long or if it has been sitting in the hot sun outside. If this happens, you will need to discard it.

The reason for this is the fact that the basil leaves used in pesto contain many different types of bacteria such as lactic acid bacteria (LAB) which breaks down proteins in food as well as creates toxins called mycotoxins.

How Long Does Pesto Last?

Some say that pesto lasts for three days, while others say it lasts for up to a week.

In general, the shelf life of pesto depends on what you use it in and other things like where you store it.

Pesto has a long shelf life due to its high oil content and low moisture level. If you want to keep your pesto fresh, make sure you use a sealed container with a tight-fitting lid and line it with plastic wrap or parchment paper. Pesto will stay fresh at room temperature for about 1-2 days.

Pesto has a shelf life of about two weeks in the refrigerator. However, it may become too bitter after that time which means you should consider making more than one batch each time you plan on using pesto.

If you need to store pesto for longer than 2 weeks, the freezer is the next option. Pesto can be stored in the freezer for 3 to 4 months.

How to Store Pesto

Whether it’s homemade pesto or store-bought, pesto can be stored at room temperature, refrigerator, or a freezer.

Room Temperature Storage

Pesto can be stored at room temperature, but it’s not recommended to do so. Storing them at room temperature will cause the pesto to not last very long.

If you need to store pesto outside of the fridge, keep them sealed in an airtight container. Also, keep the pesto away from direct sunlight and heat.

Refrigerator Storage

It is best to store the pesto in the fridge where it’s the temperature is cool. Store the pesto in an airtight container with a layer of oil at the bottom to prevent the pasta from drying out.

Freezer Storage

The freezer is the third option where to store pesto.

To store the pesto in the freezer, first transfer the pesto into a freeze-safe container. You can also freeze them as ice cubes. This will make it easier for you to remove them from the freezer.
