Watermelon Slushie
This easy Watermelon Slushie is a natural alternative to the slushies bought at gas stations and convenience stores. It’s wonderfully refreshing on a hot summer day.
Ice cold, refreshing, and bursting with watermelon flavor. That’s this drink in a nutshell.
To be honest, I rarely drink anything other than water and milk.
I know it’s strange, but ordinarily I’m not a big fan of drinking my calories, as I’d rather eat them.
But when I get my hands on a good watermelon in the summer (check out my tips for How To Pick A Good Watermelon), I make these watermelon slushies an exception.
They’re a frozen treat that’s on the healthier side, as you basically take watermelon cubes, freeze them, and blend up the “watermelon ice cubes” until you get a slushie texture.
That way you’re not diluting any of the watermelon flavor with additional ice.
To easily cut the watermelon into cubes that can be popped into the blender, see my post How to Cut a Watermelon. Enjoy!
Watermelon Slushies
Ingredients
- 2 cups seedless watermelon diced and frozen for at least 2 hours
- 2 tbsp simple syrup* optional
- 2 tbsp lime juice (Meyer lemons are great too)
- fresh mint for garnish
- lime slices for garnish
Instructions
- Place the watermelon, simple syrup (if using), and lime juice into a blender and pulse until blended. You want to make sure there are no chunks in the mixture, but do not overblend, or else you will warm the drink too much.
- Pour in a glass and serve immediately, garnished with fresh mint and a lime slice. Enjoy!

Was really good!
What do you about the seeds (assuming it’s not a seedless watermelon)?
Hi Joanne! I have a question…
I was trying to make this and it turned more into a sorbet like thing.
What did I do wrong? And does it matter what you use to mix it in??
Like I used a magic bullet…
Hi Megan, I know what you mean, and I think the watermelon was “extra” frozen. You can remedy this by adding a few cubes of room temp or refrigerated watermelon to liquefy it a bit. Hope that helps!
What are parts? (Simple syrup)
It means you would do 1 tbsp water and 1 tbsp sugar, or 1 cup of water and 1 cup of sugar. Just keep the ratio the same, but you can make as much or as little as you want.
Wow very nutritious.. great posting..
Thanks Julie =)
Can I ask what is Meyer lemon juice? Is it any different that the store brand lemon juice I find in the store or fresh squeezed? Excited to try this.
Hi Elizabeth, Meyer Lemons are very seasonal, I don’t think they’re available right now. I would suggest you use lime! Hope you enjoy the drink, it’s very simple but if you have a sweet watermelon it will be a tasty cold treat!
I just made it using lemon juice – I think I will only use half of it next time. I wanted to taste more watermelon. I also made this in a blender which required a lot of extra water to get it to mix. Do you have a special kind of blender or do you make it in a food processor?
Elizabeth, that makes sense to me. Meyer lemon is sweeter than regular lemons (many say it’s like a cross between lemon and orange) so I can only imagine how sour it would be using the full amount. I think lime would go better, but you’d probably want to add it to taste. I have a pretty powerful blender that is rated very well….you could try making it in a food processor but I’m not sure how much it’d be able to break it down. But if your blender had trouble then the food processor is certainly worth a try.
Thanks for all the info Joanne! Not giving up on this one, going to try it again with your new suggestions. 🙂
Great and extremely useful/helpful tutorial on selecting a truly tasty watermelon and cutting it up properly.
Thank you so much! Going to pick out a perfect melon when summer approaches and make the watermelon/Meyer lemon slushies! Again, I appreciate you sharing.
I am keeping this for the summer months to come.
It has been in the 70s and 80s since January and it’s been so hard restraining myself from posting recipes like this. But it is starting to warm up a bit around the country =)
