How to Freeze a Watermelon
Freezing watermelon is a great way to make use of the extra fruit for future recipes.
Line a baking sheet with a piece of parchment paper. Cut watermelon into cubes. Spread out the cubes onto the baking sheet, making sure they don't touch.
Place the baking sheet into the freezer and let freeze for 5-12 hours.
Once frozen, remove the baking sheet and place the cubes into a zip-lock baggie or stasher bag.
Keep the frozen watermelon in the freezer until ready to use.
