Watermelon Margarita Slushie

Like our Homemade Margarita Mix, these Watermelon Slushies are easy to make ahead. Simply store them in the freezer until you are ready. Full of delicious watermelon flavor and oh so cute to serve…these will be a hit!

Watermelon Margarita Slushie recipe that is a fun adult summer drink. Alcohol and watermelon mixed up in a perfect summer refreshment!

Let’s keep this post short and sweet.

Watermelon is short. Margaritas are sweet. See what I did there :).

Similar to how our Sex on a Snowbank cocktail is is all sorts of fun during winter…our watermelon margarita slushie is a summer cocktail that appeals to your adult side as well as your inner child. Well, at least it does for us. This drink would be a refreshing addition to your summer barbecue, picnic, or simply the next Thursday evening porch-sitting.

Make ahead:

Empty out the watermelon by chunks into a bowl and pop it into the freezer the night before you want to make the slushies. This frozen watermelon replaces the ice in traditional slushies. We like to pretend it’s healthier that way.

If you are serving your slushies in mini watermelons like ours, be sure to wrap them well in plastic wrap before returning to the fridge.

Day of:

Chill your Margarita making ingredients. Using warm ingredients will cause your slushie to melt far too quickly. It will still be delicious and can be served in glasses as a Watermelon Margarita instead of a frozen drink. Nothing wrong with that, at all. But if you are hoping for the slushie effect…chill your ingredients first.

Pop your blender in the freezer a half hour or so before, if you can. Not the electronic parts, for pete’s sake. This isn’t going to be a deal breaker but WILL keep your slushie cold longer. Starting off with everything as cold as possible just extends how long your slushie stays frozen and how far in advance you can make them.

We are raising our glasses mini watermelons with you. Cheers! Dang, that’s good!
