Why Blend Watermelon?

This smoothie was born after I let my 3-year-old use her kid-safe knife to cut our watermelon into chunks. Her cutting skills didn’t leave us with appealing-looking watermelon, so no one in my family wanted to eat it!

Blending it seemed like the next best thing.

To my surprise, everyone in my family adores the taste of this watermelon smoothie. I don’t normally love watermelon-flavored treats, and I also don’t love banana in my smoothie, but this simple combination creates an amazingly refreshing drink.

It’s hard to place your finger on the flavor, other than to say it tastes like you’re drinking summer in a cup.

Benefits of Watermelon

Not that you need any extra reason to eat watermelon (it’s so delicious already!), but here’s what else I love about this hydrating summer fruit.

Eating fiber-rich and water-rich foods, like watermelon, can also help keep you more regular, so I hope you’ll reach for this smoothie anytime you have extra watermelon on hand.

What Fruit Goes Well with Watermelon?

Watermelon and strawberries are a match made in heaven. They are both mild enough in flavor that they don’t compete with each other, so you get the best of both worlds when you combine them in this smoothie. And they are both in season at the same time, so you’ll get to enjoy them at their peak!

Lime is also a natural compliment to watermelon, so feel free to add a squeeze of lime juice to this watermelon smoothie recipe, if you want a slightly more tangy flavor. I like to add half of a date for sweetness, too, but that’s totally optional.

I would not use raspberries in this smoothie, since they are so tart that they might overpower the subtle flavor of the watermelon. Feel free to experiment with other tropical fruits, though, such as pineapple or mango.

Can Watermelon be Frozen for Smoothies?

Yes, you can freeze watermelon. This recipe calls for fresh watermelon, because that’s what I usually have on hand, and the watermelon here acts as part of the “liquid” base for this smoothie.

If you would rather use frozen watermelon in this recipe, I’d recommend using fresh banana and strawberries, so you won’t have to add too much extra liquid. (Which could dilute the flavor.)

  • 1 cup fresh watermelon (cut into 1-inch chunks)

  • Add the watermelon, strawberries, banana, almond milk, and date (if using) to a high-speed blender. Blend until very smooth.

I like to add the date for a little extra-sweetness, but you can also add a squeeze of honey or maple syrup, as an alternative. If you want a slight tangy flavor, add a squeeze of lemon or lime juice, to taste.

We love making this very refreshing drink, we also add a whole peeled lime 😊


Wow– I have ALL the ingredients for this at hand and I am making it tomorrow morning!! 🙂 Sounds delicious!!


Nice way to mix it up during watermelon season. I didn’t have any dates, but added a scoop of vanilla protein powder and a handful of old fashioned oats. The integrity of the smoothie was amazing, considering there’s watermelon in this.


I made this the other day and was in pure summer time heaven. Thanks for sharing!


Can I use a Cuisinart instead of the Vita-Mix


This is absolutely delicious.
instead of adding a date . I used a couple of pieces of frozen pineapple to add sweetness.
It resulted in drink the consistency of frozen yoghurt.
I would definitely make it again and have it for dessert on hot summer nights
