Watermelon Mojito: a weeknight method

A cup of watermelon mojito topped with fresh mint, lime and fresh watermelon.

This watermelon mojito is a blend of white rum, mint, lime, watermelon juice and club soda, all combined to make a refreshing beverage. The reliable cocktail for a warm day!

You can’t go wrong with cold drink recipes during the summer months. Some of my go-to options include a blue margarita, mango mojito, Mexican mule and this colorful and tasty watermelon mojito.

When it’s hot outside I always make sure to have plenty of drinks on hand to beat the heat. This watermelon mojito combines a classic summer fruit with plenty of mint for a fresh and flavorful offering!

Watermelon Mojito Ingredients

Ingredients including club soda, watermelon juice, lime and mint.

How Do You Make A Watermelon Mojito?

Add ice on top of the mint mixture, then pour in watermelon juice, lime juice, rum and club soda. Stir gently to combine, then add garnishes and serve.

Tips For The Reliable Drink

You will need to use a muddler tool to pulverize the mint leaves for the most authentic flavor. Muddlers can be purchased at kitchen supply stores or online.
This recipe makes one watermelon mojito. You can change the number of servings in the recipe card to suit the size of your group and the ingredient amounts will scale up accordingly.
I find it easiest to use store bought refrigerated watermelon juice. You can also puree 1 cup of watermelon chunks in a blender and use that instead. If you use watermelon puree, you may want to put it through a strainer before you proceed with the recipe.
Use freshly squeezed lime juice for the finest flavor.

Quick Tip

For an elegant presentation, dip the rim of your glass in water, then place the rim of the glass on a plate of sugar to get a frosted look.
