Around here, it’s not summer until we devour our first watermelon. And when I say devour… I mean DEVOUR. The second I cut into it there are multiple hands grabbing at it… and to be honest, there are rarely any leftovers.

If you think about it, it’s basically the perfect summer cocktail. Because everyone loves watermelon in summer… and when you combine it with mint, it’s always a winning combo.

These Watermelon Mojitos are easy to make by the glass or pitcher and perfect for your next summer party or day at the beach!

what you’ll need for this recipe

Mint – Fresh mint is a key ingredient in mojitos and can be found in the produce section at your local grocery store. It’s typically found in small packages in a refrigerated case, and you’ll want to be sure you choose a package that has bright green leaves without any browning.

White rum – White rum is the alcohol used in a mojito, and can be purchased at your local grocery or liquor store. The most common brand is Bacardi, but you will likely find a small variety of other brands as well. I used Bacardi.

Lime juice – Fresh lime juice is another key ingredient in a mojito, and even though this recipe uses watermelon juice I decided to add lime juice too. I always prefer fresh squeezed lime juice when possible, but bottled will work just fine.

Watermelon – Fresh watermelon is the star of the show, and the sweeter, the better! The amount you’ll need depends on how many drinks you plan to make. We found that 4 cups of watermelon chunks blends down into 3 1/12 cups of juice.

Sugar – A touch of granulated sugar adds just a bit of extra sweetness to this drink. You can also feel free to use agave, simple syrup, or omit the sugar altogether.

Club soda – Club soda is the final ingredient used to top off the drink. It adds a touch of fizz and, depending on whether you use regular or flavored club soda, can also add a touch of extra flavor.

how to make watermelon mojitos

Blend the watermelon. The first step is to make the watermelon juice by cutting your watermelon into ready-to-eat cubes, adding them to a blender, and blending on high until the mixture is smooth. Since each drink only uses 2 ounces of watermelon juice, you’ll most likely have enough juice for more than one drink.

Muddle the lime juice, sugar and mint leaves. The next step is to muddle the lime juice and sugar together, then add in the mint leaves and gently muddle some more. PRO TIP: I always “slap” the mint leaves between my hands to release the oils before adding them to a mojito. Slapping them works just the same as muddling them, but doesn’t destroy the leaves and leave little pieces floating in your drink.

Add ice, rum, and watermelon juice. Next add ice (about 2/3 full), rum, and watermelon juice.

Top with seltzer; stir & garnish. Top the mojito off with seltzer and gently stir, then garnish with mint leaves and a fresh watermelon wedge.
