    Refreshing Cucumber Watermelon Smoothie

    Beat the heat with this delicious, hydrating cucumber watermelon smoothie!

    Picture this:  It’s a hot day outside and you’ve just come in from a run.  You’re thirsty and want to replenish some of those fluid losses.  All the sudden, a handsome butler walks out holding this watermelon cucumber smoothie.

    OK, maybe the handsome butler is a bit of stretch. 😉 But you can whip this up for yourself after a run in just a few short minutes, and it is such a refreshing way to rehydrate.

    It is also ridiculously easy to make.  Seriously, you only need three ingredients:  watermelon, cucumber, and lime (plus a little water).

    The most difficult step is just remembering to keep some frozen watermelon on hand.  You can make this recipe with fresh too, but I promise it comes out better if you go through the extra step of freezing some.  What I’ve started doing is just chopping up a big watermelon for snacking each week this summer, and putting about a quarter to half of it in the freezer for smoothies.  That way it’s always on hand when you need it!

    If we’re being nit-picky, it might be more accurate to say this is a slushie than a smoothie.  I think of smoothies as creamier, usually thanks to either frozen bananas or yogurts or dairy, whereas slushies are a bit icier.  But then again, it’s fruit and veggies all blended up together in drink form, so smoothie seemed fitting as a name.

    Why You’ll Love This Recipe

    Whether you want to call it a slushie or a smoothie, you’ll definitely want to try out this recipe.  Some of my favorite highlights of this recipe:

    • No added sugar – it all comes naturally in the fruit
    • Just 63 calories – a great addition to your normal meals or snacks
    • Excellent source of Vitamin C – helpful for immunity
    • Super hydrating – great for replacing sweat losses after a workout
    • Icy cold – perfect on a hot day!

    Ingredients
      

    • 1 cup frozen watermelon
    • ½ cup cucumber, peeled & sliced
    • ½ lime, juiced
    • ¾ cup water

    Instructions
     

    • Place all ingredients in a blender and blend until well combined.  Enjoy!

    Notes

    Notes:
    • Use as much water as you need to achieve the right texture. I recommend 3/4 cup if you’re using frozen watermelon. If you prefer more of a spoonable texture, use 1/2 cup. If you prefer a very thin smoothie, use 1 cup.
    • You can also use fresh watermelon for this recipe, but the texture is better with frozen. If using fresh watermelon, cut the water down to 1/2 cup and throw in a few ice cubes.
