Freezing watermelon can extend its life for up to an entire year, but there are steps you have to take to ensure that you’re freezing your watermelon the right way.
First, slice it into any shape you prefer, and then remove the rind and seeds. Never freeze an uncut watermelon, which takes up lots of space and could potentially explode.
Line a baking sheet with parchment paper and spread the sliced watermelon across it, leaving plenty of space between the pieces, and place it in the freezer for two to three hours.
Once the fruit is frozen solid, transfer it to freezer-safe zip-top bags, making sure to write the date on them. It will be at its best for about eight months.
When you're ready for your watermelon, use it frozen or at least partially frozen. Its water content significantly decreases during thawing, resulting in a dehydrated texture.
