Fresh cut watermelon, sunny days, and a mojito in hand… that’s my idea of summer. I may not have made it to Mexico like I planned, but mixing up a pitcher of these Watermelon Mojitos on the back deck with a few girlfriends almost made up for it. Almost!
If you’re craving an easy, low-sugar cocktail that still feels like a treat, this one’s for you. It’s light, naturally sweet from the watermelon, and so refreshing. You can even skip the alcohol for a fun mocktail version.
Why These Watermelon Mojitos Are a Summer Must
✔ Naturally sweet — No added sugar needed, watermelon does the work.
✔ Quick to make — Blend, mix, and pour. That’s it.
✔ Great for gatherings — Make a big batch for BBQs, pool parties, or just because.
✔ Mocktail option — Skip the rum and enjoy a family-friendly version.
Recipe Adaptations
- Vodka: Can you use vodka in place of rum? YES! I actually prefer vodka, although classic mojitos are made with rum.
- Mocktail– Just omit the rum and you have a refreshing drink!
- Sweeter version: Some of you may enjoy something a little sweeter. The easiest way is to stir in a bit tablespoon of honey per serving. For the pitcher, 4 tablespoons and for each individual glass, add in 1 tablespoon. I prefer honey to sweeten, but you can also use simple syrup. The other option is to use Tonic water in place of seltzer water. My favorite brand is Fever Tree.
I definitely recommend sticking with a light rum like Bacardi white rum. A dark rum is going to be a much more intense flavor, and this watermelon mojito recipe is meant to be a light summer cocktail!
Feel free to try other variations with other fruit too! It would be so delicious with strawberries.
Simple Tips for the Best Mojito
- Chill the watermelon before blending — it makes the drink extra refreshing.
- Muddle fresh mint right in the pitcher or glass for that classic mojito flavor.
- I love using white rum, but vodka works too if that’s your thing.
- Want it sweeter? A splash of honey or tonic water is all you need — but honestly, it’s delicious as is.
Make-Ahead Friendly
Hosting? You can easily prep this ahead of time. Blend the watermelon, stir in lime juice and rum, and keep it chilled. When it’s time to serve, pour over ice, add mint, and top with sparkling water.
Perfect Pairings
This drink pairs so well with grilled favorites like balsamic chicken or flank steak with a berry trifle for dessert! I also love it with a crisp melon and arugula salad or a simple spinach salad. And if you want to keep the watermelon love going, try my watermelon blueberry feta salad or watermelon & prosciutto skewers.
Sipping one of these feels like summer — even if your vacation plans change. Cheers to good drinks, good friends, and sunny days!
