Why You'll Want to Freeze Watermelon
Don't waste your watermelon. Freezing watermelon and storing it is useful because fresh watermelon only lasts 2-3 days in the refrigerator or room temperature before it begins to turn to mush.
Watermelon is easy to freeze. Once cubed, watermelon takes one hour to freeze on a tray lined up separated. Bag them in freezer bags, either plastic or reusable. Frozen watermelon keeps for 12 months if sealed well.
How to use frozen watermelon. You can't thaw frozen watermelon back to a crisp texture, but if you eat it just-thawed, it is close. It is also perfect for blending into smoothies and ice creams.
Fresh watermelon is all that is needed for this process. Choose a ripe and healthy watermelon.

Step by Step Instructions
For more detail, visit the complete and printable recipe at the bottom of this post, but here are general steps.
Step 1: Wash the watermelon on the outside with warm soapy water or vinegar spray so you remove debris and germs and they don't slide into the fruit when you then cut it open.
Step 2: Cut the watermelon in half and quarters and then in slices. Next cube the fruit into 1-inch bricks. You'll be left with some odd shaped bricks, that's ok, freeze those too. Discard the rind.
Step 3: Line them on a parchment lined baking sheet, not touching. Let them freeze until hard in the freezer - about an hour.
Step 4: Pack them in freezer bags or silicon reusable bags, press out air, and write on the date.
Frozen watermelon can remain stored frozen for up to 12 months without freezer burn if enough air has been pushed out of bags and if seal is tight to prevent freezer burn.
Buy a seedless melon or pick out the seeds - don't freeze watermelon with seeds.
Choose a ripe watermelon by looking for a heavy weight, knocking on it and listening for a hollow sound, and choosing one with dull skin and stripes about 2 fingers wide.
As an alternative way to store frozen watermelon, you can also blend up fresh watermelon chunks into a puree, pour it in ice cube trays and freeze, then store the frozen cubes.
Wash the melon, slice and cube the meat, discarding the rind. Line cubes on a lined-baking sheet and freeze for one hour, then store in freezer bags.
One way to eat watermelon rind is to slice it thinly and add to vegetable stir fries. It will taste crispy like water chestnuts.
Once watermelon is frozen and thawed, it loses the crispy texture as freezing breaks down cell walls. However, if you only just thaw and eat, the taste will be crispy thanks to the icy texture given that watermelon is 90% water.
To help your fresh watermelon stay fresh longer, keep it at room temperature. The USDA says the melon will stay crisper longer than if chilled, and even healthy qualities such as antioxidants will stay fresh longer.
