Juicy, ripe red watermelon, frozen and blended into this refreshing, delicious and healthy watermelon slush! With just 3 main ingredients, this all natural, no sugar slushie recipe is the essential cool summer drink!
Don't forget to FREEZE the watermelon into bite size chunks ahead of time, at least 18-24 hours.
Remove frozen watermelon from freezer and allow to "thaw" for 5-10 minutes before starting the watermelon slush process.
Place all of the ingredients, EXCEPT the water, into a high speed blender*, add half of the water and pulse to break up the watermelon.
You will probably have to stop the blender several times and use a long spatula to dislodge frozen chunks from the blender blades -- BE SURE TO TURN OFF BLENDER before doing this step.
Add more water (or add vodka) to achieve your desired smooth, slushie blend. If the mixture is too thick, simply add a little extra water and blend until desired consistency. Immediately pour into glass and serve.
Garnish | if desired, add wheel of lime, wedge of watermelon (or watermelon balls on a cocktail stick), and a sprig of mint.
How to Rim a Glass With Sugar
If you want to rim your glass with sugar, you can do it one of several ways.
I take a piece of lime and run it around the rim of a glass, then pour about ⅛ of a cup of your favorite sugar onto a small plate and turn the glass upside down and twirl into the sugar.
You can also wet some paper towels well and dip the glass pressing into the paper towels if you prefer not to have lime on the rim.
I used all natural sprinkles, but regular white sugar, all natural cane sugar, or demerara sugar would all work great!
Notes
This recipe is easily doubled!No High Speed Blender? Add all of the ingredients to a food processor and pulse to combine, a blender just makes this recipe easier for pouring.TFC TIP | As you can see whirring the watermelon in a high speed blender will add air, muting the colors of the drink into a lighter pink; as it sits, the watermelon red will start to pop back out, but it's delicious any color!
Substitutions
This recipe is naturally SUGAR FREE and tastes delicious, but you might want to sweeten it up more:
Sweeter | As long as your watermelon is fresh, this should not need any sweetener, but if you'd like it sweeter, add 1-2 tablespoons of simple syrup or maple syrup.
Lemon for Lime | Switch up the citrus taste by using lemon juice instead of lime.
Variations
TROPICAL WATERMELON SLUSH | Add a splash or two of coconut water for a truly tropical drink, this is how my PT loves it.
WATERMELON VODKA DRINKS | Replace 3-4 oz of water with 3-4 oz of vodka, blend until smooth, this vodka cocktail has become a favorite summer drink for me and my husband.
WATERMELON VODKA COCKTAIL | Add vodka as described above, replace water with your favorite flavored seltzer water, our favorites are Limoncello or Coconut La Croix.
FIZZY WATERMELON MOCKTAIL | Our sons enjoyed this with San Pellegrino Limonata, or try any lemon-lime soda.
If you have leftover frozen watermelon drink, pour into plastic freezer container and freeze. When ready to drink again, allow to sit on counter to soften slightly for 10-15 minute, then re-blend to smooth. Since these blend up so quickly, I do not recommend blending ahead of time, unless you have room in your freezer to safely place filled glasses or the blender with the slushie in side of it.
