How to Freeze & Preserve Lemons

Updated February 17, 2017

Lemons are the perfect accompaniment to a glass of ice cold water. The summer is the best time to purchase lemons because they are fresh from the grove, and you can really taste that sweet yet tart flavour. Like so many other produce items, lemons that are purchased out of season lack a robust flavour that fresh lemons have. Fortunately, lemons are easily frozen and preserved so you may enjoy their bright, fresh flavour for months after you freeze them.

Cut the lemons into serving-sized wedges or slices. Do not attempt to freeze whole lemons unless you are just using the juice; otherwise, the pulp inside the lemon will turn mushy during the thawing process.

Place the lemon wedges on a baking tray or baking tray so they are not touching. If they touch they will freeze together and you will not be able to pull out just one lemon slice.

Transfer the baking tray to the freezer and leave them there for three to four hours, or until they are completely frozen. The length of this process depends on the thickness of your slices or wedges.

Remove the lemons from the freezer and place them in zippered freezer bags. Leave them in the freezer until you are ready to use them; then, defrost your lemon wedge or slice by allowing it to thaw on a plate in your refrigerator.


Lemons will keep in a freezer for up to three months, and will keep in a deep freezer for up to a year.
