Ingredients and substitutions
For this recipe, you'll need fresh cubed watermelon, which we'll be freezing. Try to pick the freshest, juiciest, and best in-season watermelon you can find. In-season fruit has a far superior flavor and sweetness.
Fresh mint makes these slushies extra refreshing and bright, but it can be omitted if mint is not your thing.
Maple syrup can be substituted with any sweetener you have on hand, like granulated sugar, brown sugar, or honey. If your watermelon is extra sweet, you may not need to add any sweetener at all.
Freezing fresh watermelon
To make your slushies, you'll first need to freeze your cubed watermelon. Slice your watermelon into cubes and spread in a single layer on a parchment lined baking sheet. Freeze for up to 2 hours, or until solid.
Your frozen watermelon can be stored in an airtight freezer-safe container until ready to use. Frozen watermelon will keep for up to a year in the freezer when properly stored.
Note: I also tried making these slushies with a combination of fresh watermelon and ice. The ice alone was not enough to give the drinks a slushy texture. Freezing your watermelon is definitely the way to go!
Can homemade slushies be frozen for later?
For best texture, I recommend enjoying your slushies straight from the blender. They will melt over time, just like any other frozen treat.
If you want to save some of your slushie mixture for later, it can be frozen for up to 2 hours and still have a scoopable texture (more like a sorbet than a slushy). Longer than two hours and your homemade slushie will freeze into a solid block.

Equipment Recommendations
Notes
- ¼ of a large seedless watermelon = about 32 ounces of cubed watermelon
- Maple syrup can be substituted with any sweetener you have on hand (granulated sugar, honey, brown sugar) and can be omitted if your watermelon is in-season and very sweet. Out of season watermelon will need the added sweetener.
- Your homemade slushie can be frozen for up to 2 hours, but will freeze solid over time.
