Naturally sweet, this homemade watermelon slushie can be enjoyed as-is or spiked for the adults. On hot summer days when I’m chasing kids around the backyard, this healthy watermelon slushie is a great way to stay hydrated since watermelon is about 92% water. And when we want to switch things up, this frozen protein yogurt is just as refreshing.
What I love most about this healthy slushie is that it's just 3 ingredients, a quick blend, and you’ve got a thick, icy treat in under 5 minutes (using frozen watermelon helps keep it from getting watery!). It’s become one of our go-to summer drinks right alongsidea salted caramel protein shake paired with frozen chocolate-covered bananas.

Ingredients and Substitutions
- Watermelon: Frozen watermelon chunks work best for the slushie recipe, as it makes a thicker, icier texture. However, fresh watermelon can work in a pinch.
- Perrier: The easiest way to make something "fancy" is to add a bit of fizz! This is my staple when it comes to healthy mocktails, too. While you can use flavored Perrier, the original works just fine.
- Lime Juice: totally optional, but a great addition! Lime juice gives a burst of flavor and energy. You can either use the lime juice right in the watermelon slushie or use wedges as a garnish.

How To Make A Watermelon Slushie

Expert Tips
Frozen watermelon creates a thicker watermelon slushie. If using fresh watermelon, you'll definitely want to use frozen strawberries to help balance it out.
For the best texture, serve the non-alcoholic watermelon slushie immediately. Storing it in the fridge causes the slushie to lose its refreshing texture and thin out.
Watermelon Slushie FAQs
To keep your slushy from getting watery, make sure to first allow any excess water drip from the watermelon before freezing. Use frozen fruit to maximize the chill in the slushy, and do not add water while blending. Once frozen and blended, keep your slushy in a cool place, as it will thin out as it melts.
Frozen watermelon works best when making slushies. If you don't have frozen watermelon, use a frozen fruit in the slushy and ice as needed until you get the right texture.
You can make leftover slushy into popsicles, but know that because they're so high in water, they come out a bit icy and not creamy.

I found this after trying to figure out what to do with some cubed watermelon that was about to kick the bucket. I threw it in the freezer and made this the next day. Honestly, I wasn't expecting much, but whoa, was I blown away! It was seriously so good, and I am buying a watermelon just so I can cube and freeze it to make this! lol Thanks for sharing!
