These Cucumber & Watermelon Mojitos are going to become your go-to summer drink – serve them in an ice-cold pitcher on a hot day!

Ingredients and substitutions
- Watermelon – use fresh or frozen watermelon or a pureed watermelon mixture.
- English cucumber – use pureed cucumbers with slices of cucumber for garnish.
- Lime – I suggest fresh lime juice for this recipe, but bottled lime juice will work in a pinch.
- Mint – muddled mint is best. Fresh mint will be used to garnish.
- Vodka – white rum can also be used to create an authentic mojito.
- Sparkling water – use any brand of your choice or substitute for club soda.

How to make watermelon mojitos
- Puree the watermelon and cucumber.
- Strain to remove the pulp.
- Juice the limes and muddle the mint.
- Shake with ice then strain into a pitcher.
- Add the rest of the ingredients to the pitcher.
- Pour over ice and enjoy!

Non-alcoholic mojitos
If you're hosting a kid-friendly barbecue or just prefer not to drink alcohol, you don't have to miss out on this delicious summer drink! Take out the alcohol, add some watermelon juice or more sparkling water and you have yourself a delicious virgin mojito. Serve and enjoy all night, without the hangover! The watermelon and cucumber make this drink super refreshing, so it’s the perfect drink for any summer gathering. Don't forget to throw into some flavoured ice cubes, too!

Frequently Asked Questions
Watermelon tastes great with vodka, rum, tequila and gin. For this recipe, I used vodka, but feel free to swap it out for another liquor of your choice!
A mojito is typically made with lime juice, simple syrup, muddled mint and rum. I used vodka instead of rum for this mojito to cut down on the calories and skipped the simple syrup since the watermelon provides plenty of sweetness on its own.
This cucumber and watermelon mojito has 160 calories per drink. It’s the perfect refreshing summer beverage that doesn’t go overboard on the calories like some sweet cocktails!
A margarita is a cocktail that can be served frozen or on the rocks, made with tequila and salt on the rim. A mojito is a cocktail that is made out of rum (I use vodka in this recipe to save on any extra calories) and mint that is muddled with fresh citrus juice. Mojitos are typically seen as a healthier drink option than margaritas but they're just as good!

Loved this recipe! The perfect refreshing summer drink!
Taylor Stinson says
I’m so happy you enjoyed 🙂
Mackenzie says
Could you make the puree ahead of time? say 2 days in advance? I wanted to bring these to a cottage but wont have a blender!
Taylor Stinson says
Hey Mackenzie – I imagine it would work! I’ve made it up to a day in advance and it’s been fine. The only thing I would say is that it might cause a bit of discoloration but the taste would remain the same after two days. Let me know if you try it!
cynthia says
We froze the Watermelon, lime & cucumber juice together in a gallon container.
4 days later (welcome drink for wedding)
thawed the juice, added the mint, vodka and bubbles.
it was delicious!!!
Katie says
Can’t wait to try it out!!
I’m also wondering how big of a watermelon to use or if I were to use fresh pressed watermelon juice, how many oz’s or cups?
Taylor Stinson says
Hi Katie – I used a small-sized seedless watermelon..maybe 8-10 inches in diameter around if I had to guess. Hope that helps!
Katie says
Yes it does, thank you!
So like one of the mini mellons?
Taylor Stinson says
Yeah one of those should work 🙂
Emily says
do you peel the cucumber first?
Taylor Stinson says
I personally don’t but you could if you wanted to!
Angela Allen says
Looks like my new favorite drink! What size watermelon? ?
Susmitha Saripalli says
aren’t mojitos made with rum?
Taylor Stinson says
Hi Sudmitha! Traditionally, yes they are. I personally think the vodka goes way better with the watermelon and cucumber though. Feel free to add in rum if you want to keep it more of a classic mojito though!
Mark says
