Have I mentioned how much I love smoothies?

I love that simple, healthy ingredients can be mixed together to make something so delicious and creamy, like today’s recipe for a strawberry watermelon smoothie. It’s so sweet and satisfying! The combo of strawberries and watermelon are a match made in heaven. Look at the pink color of this smoothie– so beautiful (just as pretty as our Aloha Tropical Smoothie and Strawberry Oatmeal Smoothie).

This is the perfect treat to slow down and enjoy every tasty sip. My kids love smoothies for breakfast or even an after-school snack. It’s a great way to get them to sit down and talk about what they did and learned at school!

Plus this watermelon smoothie gives us all the energy to get through the rest of the day until dinner time. Top each cup with a little slice of watermelon and/or a strawberry (pictured above!).

How to Make a watermelon smoothie

The best thing about smoothies is how easy they are to make!

BLEND. Cut up some watermelon into cubes- about 1 ½ cups. And you need 1 cup of strawberries that are trimmed. Throw those fruits into a blender with milk, lemon juice, and 2 SPLENDA® Naturals Stevia Sweetener packets. Blend all of it together with ½ cup of ice! Pour into glasses and savor every sip!

Note. After a little bit of testing, we have the recipe down so that it’s the perfect amount of strawberry AND watermelon. We wanted to be able to taste both fruits equally and enjoyably. This easy watermelon strawberry smoothie recipe is perfection!

Tips + Storing Info

For tips about picking out a good watermelon we did a whole blog post. Check it out HERE.

For the best way to cut a watermelon for this recipe we’ve got you covered!

Mix it up by adding other fruit in with the watermelon. That depends on what you prefer, but these other combos work great and taste delicious:

  • watermelon + blackberries
  • watermelon + blueberries + peaches
  • watermelon + fresh lime/lemon juice + raspberry juice + mint

Prep ingredients ahead of time for quick smoothies when the craving hits. Wash, slice, and divide the fruit into individual sized portions and keep them in Ziploc bags in the freezer. The yogurt can be frozen in an ice cube tray. The ice and juice are best added to the smoothie right before mixing. With the ingredients prepped like this, you can take the ingredients straight from the freezer to the blender!

To STORE leftovers, add a little bit of lemon juice or Sure Fresh so the smoothie doesn’t brown. If there’s a little room at the top of the container, cut a piece of plastic wrap and place it directly onto the top of the smoothie. Store in the fridge for 12 hours or in the freezer for up to 3 months.

    Watermelon and any other fruit makes great smoothies. But i don’t think the Splenda is necessary. Watermelon’s natural Sweetness is more thAn enough. I try to stay away from any artificial sweetener as well as sugar.
