Watermelon Margaritas

Margaritas are my favorite cocktail, so I’m always looking for new ways to jazz them up or new margarita recipes to try. I’m so excited to share this fruity Watermelon Margarita with you guys!

There’s still a month of summer left, and actually it feels like summer a lot longer than that here in Texas! We’ve been dealing with record-breaking heat for weeks, so a refreshing drink is definitely a must sometimes!

This recipe uses fresh fruit and watermelons are in season, so it’s the perfect time to whip up a batch of Watermelon Margaritas! Grab a watermelon next time you’re at the store and let’s get mixing!

I’ll show you how to make both on-the-rocks or a frozen version. Both are easy and delicious and you really can taste the sweet flavor of the watermelon!

“On the Rocks” Instructions

To Prep: Cut the watermelon into chunks and remove the rind.

  1. Add watermelon pieces, tequila, triple sec, lime juice, margarita mix, and agave syrup to a blender.
  2. Puree until completely smooth, with no large chunks of fruit.
  3. Pour the mixture through a strainer to remove any remaining pulp.
  4. Serve on the rocks (in a glass full of ice cubes), with or without salt.

Frozen Watermelon Margaritas Instructions

To Prep: Cut the watermelon into chunks and remove the rind. Place the watermelon chunks in a freezer safe container and into the freezer until frozen solid.

  1. Add all ingredients to a large blender with 1 cup of ice cubes.
  2. Blend on frozen drink mode (or medium to high speed).
  3. When your margarita mixture is smooth and has a slushy consistency, pour into your prepared glasses. If the mixture is too thick to drink through a straw, add a bit more liquid (you can add a splash of tequila, triple sec, and lime juice to keep it flavorful). If the mixture is too watery, add another cup of ice and blend again.

Prep Tips

  • For a spicy kick, instead of coating the rim of the glass with margarita salt, try using Tajin (chili lime seasoning) instead.
  • Garnish with a lime wedge or fresh watermelon slice.
  • Using a seedless watermelon will speed up the process a bit because you don’t need to remove all the seeds one by one.

Frequently Asked Questions

Can You Use Watermelon Juice Instead?

Yes, you can start with fresh watermelon juice if you’d like to skip the step of cutting and juicing your own. Be sure to use pulp-free juice or strain it first!

If using watermelon juice, you’ll need 3 cups (instead of 4 cups of watermelon cubes). If making frozen watermelon margaritas, you’ll want to freeze the juice into cubes first.

What is the Best Tequila to Use in a Margarita?

With a margarita, you can really use any type of tequila, so it’s up to you! Since this drink is pink in color, you can use either gold or silver tequila. The type of tequila won’t affect the color of your cocktail.

Quality-wise, I always recommend using a mid-range liquor. Too expensive, and it’s a bit of a waste since you won’t be tasting the nuanced flavors of an aged tequila. Too cheap, well, I don’t think I need to explain why you might not want to use the cheapest tequila!

Can You Make A Single Serving Instead?

Since you’re going to the trouble of juicing watermelon, I went ahead and designed this recipe to make a pitcher’s worth. However, if you want to make just one serving, you can easily do that too!

Here’s what you need for one serving:

  • 1 ounce tequila
  • 1 ounce triple sec
  • 1 Tablespoon lime juice
  • 1/2 ounce sweetener
  • 4 ounces watermelon juice

Add ingredients to a cocktail shaker with ice, shake for 5 seconds to chill, and pour the contents of the shaker into a salt-rimmed glass.
