How Long Lemon Zest Will Last In Your Fridge And Freezer

If you're not planning to use fresh lemon zest straight away, the good news is that the peel keeps well in the refrigerator for around a week if stored in an airtight container.

However, your best bet would be still to freeze the zest. If you keep it in a resealable bag or an airtight container, lemon zest can last for up to a year in the freezer.

The best bit is that you don't need to defrost frozen zest. If a recipe calls for zest and you don't have any lemons handy, the zest in your freezer is all you need to reach for.
