Ingredients & Substitutions

Perhaps my favorite thing about this frozen watermelon margaritas recipe is that it’s made with just a handful of real, easy-to-pronounce ingredients. Here’s what to grab:

  • Watermelon – You’ll need to de-seed and peel it before blending, but there’s no need to strain after you’re done. Feel free to opt for a seedless watermelon to cut back on prep.
  • Tequila Blanco – This is the most neutral-flavored tequila option, which is perfect for letting the juicy beauty of the watermelon shine. In a pinch, you can use reposado instead.
  • Sugar – For balancing out the flavors of this frozen watermelon cocktail. Feel free to swap in the sugar alternative of your choice (e.g. stevia or monkfruit).
  • Lime Juice – Make sure you’re reaching for fresh limes for the brightest, most delicious flavor. 
  • Mint – Want an easy way to cut down on expenses? Plant mint in some containers in your garden. They’ll grow like wildfire, so you’ll always have plenty on hand for all your favorite cocktails and desserts! Then, at the end of the season, cut back all the stems, bunch them together, and hang upside down until the leaves are dry and crispy. The root bulb will lay dormant through winter and bloom again when spring returns!

Optional Variations

While I think this is the best watermelon margarita recipe around, there are plenty of ways for you to make it your own. Here are a few ideas to get you started:

  • Rim It. Dip the rim of your (empty!) glass in agave or run a cut lime around the edge. Dip into a plate filled with coarse salt and/or sugar mixed with fresh lime zest for a little added flavor and sparkle. 
  • Spicy Watermelon Margarita – In the mood for a tongue-tingling combo? Make a frozen watermelon jalapeño margarita by tossing in ½ – 1 sliced and seeded jalapeño, or add more to taste. Add a Tajin rim for added spice!
  • Watermelon Margarita on the Rocks – Wondering how to make a watermelon margarita without having it give you a brain freeze? Not to worry. Blend unfrozen watermelon, sugar, lime juice, and a splash of water until smooth. Pour through a fine mesh strainer to remove the pulp. Pour the watermelon juice mixture over ice, add a shot of tequila, stir and serve!

Expert Tips

  • Cube & freeze watermelon while it’s in season so you can enjoy it all year long. I tend to make these delicious watermelon mint margaritas all the way up until Halloween because I’m a true summer girl at heart.

Frequently Asked Questions

What happens to watermelon when allowed to freeze in the freezer?

When you pop watermelon into the freezer, things get a little frosty. Here’s the scoop on what happens:

As the watermelon freezes, ice crystals start forming inside the fruit. These ice crystals break down the cell walls and insides of the fruit, causing them to change texture. After freezing, you’re not going to want to try and serve them fresh! But don’t worry, even if frozen watermelon isn’t exactly the same as fresh-off-the-vine stuff, it can still be a star player in smoothies, slushies, and, of course, these delectable Frozen Watermelon Margaritas!

How do you make frozen margaritas less runny?

One of the easiest ways to thicken your frozen margaritas is to use frozen fruit. For these Frozen Watermelon Margaritas, make sure the watermelon chunks are frozen before blending to create a thicker base.

If your margarita mixture is still too runny, add more frozen fruit or some ice to the blender and re-blend. Just be cautious not to overdo it, as adding too much ice could dilute the flavor. Also, don’t go overboard with blending. Blend the margarita mixture just until you achieve the desired consistency. 

Finally, consider freezing your serving glasses ahead of time. Pouring your freshly blended frozen margs into frosty glasses will help keep them cooler for longer, prolonging the perfect texture long enough for you to slurp it all down!

Do frozen margaritas have less alcohol?

It all depends on the margarita, I suppose. Here I like to add a 2 ounce shot of tequila, making this frozen margarita recipe on par with most of my other cocktail recipes.
