To properly store pesto, place it in a jar with a small amount of olive oil on top to prevent it from browning. Keep the jar in the refrigerator for up to one week. Alternatively, you can freeze the pesto for up to three months by pouring it into an ice cube tray. Once it's frozen solid, pop out the cubes and transfer it to a freezer bag. Allow it to thaw in the fridge overnight before using.
