Ingredients
- 3 cups diced seedless watermelon (450 g), chilled

- 10 fresh mint leaves, plus extra for garnish

Ingredient Notes and Substitutions
Use ripe, sweet watermelon for the best flavor. Choose a watermelon that feels heavy for its size, has a creamy yellow field spot, and makes a deep hollow sound when tapped. For more helpful tips, see The Kitchn’s guide to picking a ripe watermelon.
Lime works better than lemon here because it gives the drink a fresher mojito-style flavor.
Use Sprite or another lemon-lime soda for a sweeter drink. For a less sweet version, use sparkling water or club soda and keep the full tablespoon of sugar.
Fresh mint is important. Do not skip it because it gives the drink its classic mojito flavor. For another cool drink with fresh mint and bright citrus, try this Fresh Cucumber Lemonade with Mint. Its crisp cucumber flavor makes it another refreshing choice for hot summer days.
Salt is optional. Add only a very tiny pinch if using sparkling water, as it can bring out the sweetness of the watermelon.
How to Make Watermelon Mojito
- Cut the watermelon into small cubes and remove any visible seeds.
- Divide the watermelon, mint leaves, lime juice, lime slices, and sugar between two tall glasses.
- Use a muddler or the back of a wooden spoon to gently press the watermelon and mint together. Press lightly and give the mint only a few gentle twists rather than crushing or shredding it. Over-muddling mint can release bitter flavors into the drink. See Serious Eats’ guide to muddling mint for more helpful tips.
- Fill each glass with ice cubes.
- Pour Sprite or sparkling water over the ice.
- Stir gently until the sugar dissolves.
- Garnish with extra watermelon, mint leaves, and a lime slice.

- Serve immediately while the drink is cold and fizzy.

Expert Tips for the Best Watermelon Mojito
- Use chilled watermelon so the drink stays cold longer.
- Remove black seeds before muddling the watermelon.
- Muddle the mint gently to avoid a bitter flavor.
- Use Sprite for a sweeter mocktail.
- Use sparkling water for a lighter drink.
- Add the soda only right before serving.
- Do not prepare the finished drink too early because the bubbles will disappear.
- Freeze watermelon cubes and use them instead of regular ice for extra flavor without watering down the drink. Arrange the cubes in a single layer on a parchment-lined tray, freeze until firm, then transfer them to a freezer bag. See The Kitchn’s melon ice cube guide for the easy method.
Storage and Freezing
This watermelon mojito is best served immediately.
You can prepare the muddled watermelon, mint, lime, and sugar mixture up to 1 day ahead. Keep it covered in the refrigerator, then add ice and soda just before serving.
Do not freeze the finished drink. You can freeze watermelon cubes for up to 1 month and use them as flavored ice cubes.
Can I Make This Watermelon Mojito in a Pitcher?
Yes. To make a pitcher, muddle the watermelon, mint, lime, and sugar together first, then refrigerate the mixture until ready to serve. Add the Sprite or sparkling water just before serving so the drink stays fizzy.
Variations
Sparkling Water Watermelon Mojito

Frozen Watermelon Mojito

Strawberry Watermelon Mojito
