Watermelon Mojito

The most delicious, refreshing and light cocktail that screams summer! This Watermelon Mojito is refined sugar-free, made with fresh mint and juicy watermelon and is the perfect cocktail (or ‘mocktail’) to enjoy on a hot day.

Prep: 10 minTotal: 10 min
Servings: 2-3 servings 1x


  • 8 large seedless watermelon cubes or ¾ lb. – 1 lb. (about  1 – 1 ½ cups juice) 
  • 2 oz. lime juice or juice of 1 lime (~¼ cup)
  • 1 tsp. honey or agave nectar (optional – taste the watermelon juice before adding)
  • 1520 mint leaves (~ ⅓ cup)
  • 34 ½ oz white rum* (substitute sparkling water or kombucha for a mocktail version)
  • sparkling water (regular or lime flavor)
  • Ice


  1. In a blender, add the watermelon cubes. Blend until smooth, achieving a juice consistency.
  2. If watermelon juice appears pulpy, pour through a mesh strainer into a mason jar or large glass. This step is optional.
  3. To the mason jar or glass with the watermelon juice, add the lime juice and optional sweetener. Stir to combine.
  4. Divide the mint leaves among 2-3 tall glass. With the end of a wooden spoon or a muddle, muddle the mint. Essentially you want to smash the mint leaves until all leaves are darker in color and slightly wilted. Feel free to add a small squeeze of lime juice during this step to help the leaves breakdown easier.
  5. Fill each glass 3/4 full with ice. Divide the watermelon lime juice among the 2-3 glasses. Add 1.5 oz. of white rum to each glass. For a mocktail, use sparkling water in place of the rum. Top each glass off with a splash of sparkling water (lime flavor works great!).
  6. Stir and enjoy!


To make ahead: Feel free to make the watermelon juice up to 48 hours in advance. Juice will separate so you’ll want to give it a quick stir before making the drinks.

*To make as a mocktail: Omit the rum and replace with sparkling water or kombucha, if desired
