    Strawberry Watermelon Slushy

    Enjoy a burst of hydration with this fizzy watermelon slushie recipe! With only three ingredients it's easy to whip up and the perfect way to cool down on a summer's day.

    Naturally sweetened, you can enjoy this watermelon slushie virgin as is or spiked. We all know we need to keep our water intake high, especially in the summer months. And since watermelon is 92% water, it's the perfect food to get the job done!

    Watermelon is also the perfect drink to sip on because it's so low in calories- just like naturally flavored water!

    This watermelon slushie recipe contains only three ingredients and you won't believe that it comes together in under 5 minutes!

    As a Certified Nutrition Coach, it's a total summertime staple (as are these frozen chocolate-covered bananas!)

    This slushie is:

    • quick to make
    • refreshing
    • hydrating
    • a great way to fuel up while still playing

     

    Ingredients You Need To Make The Recipe

    As mentioned, this recipe only requires three ingredients keeping it ultra-simple!

    Watermelon: frozen watermelon chunks work best for the slushie and definitely ups the "cool" factor of it. However, fresh watermelon will work as well!

    Strawberries: the slushy is naturally sweetened (and naturally pink!) from strawberries! Again, frozen will create a better, chunkier texture but both will work.

    Perrier: the easiest way to make something "fancy" is to add a bit of fizz! This is my staple when it comes to healthy mocktails too. While you can use flavored Perrier, the original works just fine.

    Lime Juice: totally optional but a great addition! Lime juice gives a burst of flavor and energy. You can either use the lime juice right in the watermelon slushie or use wedges as a garnish.

    How To Make A Spiked Watermelon Slush

    One of the most fun things about this fizzy watermelon slushy recipe is that it's fun for kids (virgin!) and adults (spiked!).

    If you want to make a Watermelon Slush Cocktail, simply use the additions below:

    • 2 shots of your favorite vodka (does anyone else adore Titos?
    • Add 5 more strawberries or 3 more ice cubes

    Garnish with lime juice and indulge!

    And of course, if you need some inspiration for more summer alcohol drinks, check out this pineapple slush and these easy vodka cocktails!

    How To Make Watermelon Slushies

    1. Add all ingredients except perrier to a high-powered blender.
    2. Process until combined and semi-smooth (you don't want it too thin).
    3. Pour into glasses and add in perrier water.
    4. Garnish with a lime (or lime juice), or fresh mint and serve.

    Important Teaching Tips

    Frozen watermelon chunks will create a thicker watermelon slush (and chunkier) than fresh watermelon.

    You can use flavored perrier water but the recipe is delicious with regular.

    Lime juice added onto the top (or lime zest) creates an ultra-refreshing flavor. Note that some people love lemon juice as a flavor combo instead!

    Frequently Asked Questions About The Fizzy Watermelon Slushie Recipe


    Is frozen watermelon healthy?

    Yes! watermelon is loaded with water but also some crucial nutrients. It's an easy way to stay hydrated in warmer weather. You can eat watermelon as it, however, many people enjoy freezing watermelon and using them in watermelon slush or as watermelon ice cubes!

    Can you blend watermelon seeds?

    Though you can blend the watermelon seeds, most people won't enjoy the texture of them in a drink. If making watermelon juice you can strain the pulp and seeds out after blending. However, if making watermelon slushies you'll want to remove the black seeds prior to blending.

    Ingredients
      

    • 3 cups chopped watermelon seeded
    • 7 strawberries
    • 5 ice cubes
    • 1 can Perrier original

    Instructions

    • You can garnish the watermelon slush with a slice of lime or fresh mint.

      I found this after trying to figure out what to do with some cubed watermelon that was about to kick the bucket. I threw it in the freezer and made this the next day. Honestly, I wasn't expecting much, but whoa, was I blown away! It was seriously so good, and I am buying a watermelon just so I can cube and freeze it to make this! lol Thanks for sharing!
