What is the Best Way to Freeze Pesto?
The method you use to freeze your pesto will depend on how you want to use the sauce. If you plan on using your pesto as a pasta sauce, it's best to freeze it in big batches. But if you think you'll want to use the pesto to add flavoring to your dish, freezing it in small batches is a great idea.
To freeze a full batch of pesto, prepare the sauce according to the recipe and transfer it to a freezer-safe container. The pesto can be stored in a freezer bag and stored flat in the freezer to save space. Or you can store the sauce in a glass jar or airtight plastic container.
But if you want to store your pesto in small batches to add pesto flavoring to your dishes, just use your ice cube tray. Once the sauce is fully frozen, you can transfer the pesto cubes to a freezer bag for easy storage.

How to Thaw Frozen Pesto

Another option is to thaw the pesto cubes to use them as a sauce, spread, or dip. If you have time, the best way to thaw your frozen pesto is to transfer it to the refrigerator. But if you're short on time, simply place the pesto cubes in a microwave safe dish and thaw them using the defrost setting on your microwave.
Will Frozen Pesto Turn Brown?
Since pesto is made with fresh, leafy greens, there is a possibility that it will turn brown while it's freezing. While the pesto is still good, even if it's brown, it doesn't look very appetizing!
There are a couple of ways you can prevent your pesto from turning brown in the freezer. The key to keeping your pesto green is to prevent air from coming into contact with the basil in the freezer. One simple way to do this is to cover the ice cube container with plastic wrap before freezing it. Or simply add a few drops of additional olive oil to the top of each cube before freezing.

Once your pesto sauce is frozen solid, it will stay good for up to six months. To ensure you don't let your fresh pesto go bad in the freezer, make sure to store it in an airtight container.
