During the hot summer months, I always have a watermelon in my fridge. It makes the perfect snack after a long, hot day of gardening, and I’ve found they’re also great for making refreshing summer drinks like this watermelon margarita!

Watermelon is perfect for adding natural sweetness and a vibrant pink hue to your margarita. You can use ripe or slightly overripe watermelons—it’s all good!

Watermelon Margarita Ingredients

This ingredient list is simple yet packed with flavor! Here’s a breakdown with some tips and potential substitutions:

Watermelon: The star of the show. Make sure it’s ripe for the sweetest flavor. A seedless watermelon is easier to use as you don’t have to worry about picking out the seeds. If using a seeded watermelon, remove the seeds first.
Tequila: Go for a good quality blanco tequila for a smooth finish. My favorite is 1800 Blanco Tequila. (Not sponsored, it’s just my favorite).
Lime Juice: Freshly squeezed lime juice is a must. It adds the perfect flavor.
Agave Syrup: This sweetener blends perfectly without overpowering the drink. You can substitute it with simple syrup or honey.
Triple Sec: Adds a hint of citrusy sweetness. You can also use Cointreau instead.

You’ll also need salt or sugar for rimming your glasses, and some lime wedges for garnish.

FAQs about Watermelon Margarita

Yes, you can use fresh watermelon, but you’ll have to add ice cubes to get a slushy consistency.

You can cut up and freeze the watermelon cubes in advance, but I wouldn’t blend them up until just before serving; otherwise, the margaritas won’t be thick and slushy.

Yes, you can use other fruits like strawberries, mangoes, or pineapples. Just follow the same basic steps for blending and mixing.
