Simple rinse and dry the avocados thoroughly then wrap them individually in plastic wrap or beeswax wrap.Optionally also place them within a larger Ziplock bag. They will last for up to 4 months in the freezer
Avocado halves or quarters
Hold the avocado in the palm of your non-dominant hand and use a sharp pairing knife to cut it in half lengthwise, allow it to reach the pit in the middle, and rotating the avocado as you do to slice all the way around it.
Pull the avocado apart and remove the pit by firmly (but carefully) tapping into it with your knife and pulling it away.
Slice the avocado halves in half once more to create quarters and remove the peel.
Dip, brush, or rub the chopped avocado immediately with lemon or lime juice and wrap them in plastic wrap/beeswax wrap to place in a freezer bag.They will last about 2-3 months in the freezer.
Avocado chunks and slices
After opening it and removing the pit, you can then either dice or slice the avocado flesh within the peel first (be careful not to push the knife all the way through the peel) OR remove the peel and slice/dice it against a chopping board.If you’re doing the first, running a knife along the outer edge of the avocado can help make it easier to either scoop out (with a spoon) or push/press loose from the peel.
Coat the pieces in lime/lemon juice and spread them across a baking sheet to flash freeze until solid (cover with plastic wrap while freezing) for an hour.
Transfer to a freezer bag and squeeze out the excess air.They will last about 2-3 months in the freezer.
Mashed avocado
Peel, chop, and mash the avocado with a sturdy fork or mini food processor.
Add some lemon or lime juice to the mash and mix it in well.
Transfer the mash/avocado puree to a freezer-safe container or ice cube trays and optionally (highly recommended) top with a thin layer of water, lemon juice, or oil.
When you thaw the mashed avocado, simply pour off the top layer, re-mix, and enjoy.Alternatively, you can freeze it spread flat in a Ziplock bag will all the excess air removed. However, you may still need to scrape off an upper layer as it will likely brown more.It will last about 2-3 months in the freezer.
Notes
Use ripe avocado: It should have some give when squeezed but not be overly hard or soft. You can also test for ripeness with the stem. If it doesn’t come off, the avocado is likely underripe, if it comes off easily and is green or only lightly browning underneath, your avocado is ripe. If it’s brown, it’s likely overripe.
Use a sharp knife: So you don't accidentally mash and ‘butcher’ the avocado when getting it ready to freeze.
Use lemon or lime juice: If you’re freezing anything other than whole avocados, then make sure to coat them in citrus juice to maintain color and slow oxidization.
Remove excess air: Another important tip to reduce oxidization is to ensure you squeeze out (or suck out with a straw) any excess air from the freezer bag.
