Ingredients needed for this watermelon slushie
To make this icy watermelon treat, you’ll need:
- ½ watermelon (about 2.5kg from a 5kg whole watermelon)

This recipe is flexible and can be adjusted to taste. If your watermelon is extra sweet, feel free to skip or reduce the maple syrup.
How to make a watermelon slushie
Follow these simple steps to create your very own healthy watermelon slushie at home:
- Scoop and freeze: Cut your watermelon in half and scoop out the flesh of one half. Place it into a large container and freeze for at least 4 hours, or overnight.
- Prep the limes: Juice the limes and remove any seeds.
- Soften the watermelon: Take the frozen watermelon out of the freezer and let it sit at room temperature for 20 minutes. Alternatively, microwave it for 1 minute to slightly soften and separate the frozen pieces.
- Blend: Add the frozen watermelon, lime juice, maple syrup, salt, and water to a high-speed blender. Blend until you reach a smooth, slushie consistency. You may need to stop and scrape the sides or stir between pulses depending on your blender.
Tips and tricks for the perfect watermelon slushie
- Use ripe watermelon: The sweeter and redder the watermelon, the better your slushie will taste.
- Use a seedless watermelon: It's easiest to buy a seedless watermelon. Otherwise it will be time consuming to remove the seeds before freezing and blending.
- Avoid over-blending: Blend just until slushie-like to maintain that icy texture.
- Lime juice is key: Don’t skip the lime—it enhances the natural sweetness of the watermelon and balances the flavors.
- Don't skip the salt: A pinch of salt brings out the sweetness without making the drink salty.
