If you are opting to freeze leftover watermelon, there are a few ways to go about it. But the first step to perfectly usable frozen watermelon is always the same: pick the best melon you can.
From there, you’ll want to break down the watermelon—in cubes, or using a melon baller. Don’t forget to take advantage of the watermelon rind, which actually has some health benefits (or can even be used in a face mask.)
After cubing it, you’ve got two options: if you don’t mind having to hack apart the frozen pieces of watermelon when you want to use it, you can simply put it in a container. But “the best way to freeze watermelon is to cube it and place it on a baking tray,” says Sarah Thomas-Drawbaugh, recipe developer and founder of Healthyish Foods.
It will take a few hours for the watermelon to freeze, and then it will last from 8 to 12 months—so you can stretch your watermelon supply long beyond the summer months.
