This Strawberry Watermelon Smoothie is my favorite summertime refreshing smoothie! This simple combination never gets old and it’s equally popular with kids or adults. The sweet berry flavor pairs perfectly with the juicy watermelon. It’s frosty cold and a touch of mint makes it even more refreshing as a variation. There’s no bananas involved in this smoothie, just 3 simple ingredients. It’s also gluten free, dairy free, vegan, and paleo as well.
This smoothie is summer in a glass! It’s so refreshing whenever temperatures soar, and it’s perfect for summertime activities. I first started making this smoothie after we hiked a steep mountain in the blazing summer sun.
It was super hot, and when we got back I started foraging the fridge and found some watermelon. From there I blended it with frozen strawberries and downed a 32-ounce jar in record time. It’s definitely the perfect thirst quencher.
It’s been about 10 years now since we first made this smoothie, and it’s still our summertime favorite! I get the craziest looks, (and comments) when people see me pushing my grocery cart with 3 gigantic watermelons in it. Or even more comical when I try and bring home 20+ pounds of watermelon from the local farmer’s market!
People think I must be throwing the biggest BBQ party ever. And they’re always stunned to learn I’m actually just buying that much watermelon for me and my husband. Since we’re both crazy about watermelon, we tend to go through a lot!
We’ve developed a couple of watermelon drinks and smoothies over time. So you’ll be seeing our favorite drink to take hiking soon – the Watermelon Thirst Quencher. I never quite got around to getting the measurements down last year. But this year’s a different story, and I’ve got you covered in the watermelon department this season!
Let’s get started by talking about the ingredients for this Strawberry Watermelon Smoothie
- Watermelon – either fresh or frozen works here in this smoothie. In fact I love using frozen watermelon along with frozen berries for a super frosty smoothie. This smoothie is super simple, so it really matters that you have a great tasting watermelon. Otherwise your smoothie will be bland.
- Strawberries – I always use frozen berries here with either fresh or frozen watermelon.
- Lemon or lime juice – fresh is a must here because you can really taste the difference in this simple smoothie. Just a touch of zippy citrus juice goes a long ways towards pulling the flavors together and keeping this from being too sweet.
- Mint – is a fun variation I love but Tyler isn’t as fond of. Only add it if you love the fresh flavor of mint, and don’t be tempted to add to much. I like to blend the smoothie first, then add a few mint leave in the end and blend only until little green bits remain.
Now let’s make this Strawberry Watermelon Smoothie recipe step by step
First we’ll start by removing the rind from the watermelon. I had some mini watermelons, so I cut all the rind off like you would for an orange. But when I have regular sized watermelon, I cut slices first. Then I cut cubes across the slices before cutting off the watermelon rind, leaving the cubes behind.
Cube up your watermelon. I like to keep the cubes small so I can fit more in the blender.
Measure out the frozen strawberries, and juice the lemon or lime.
Next add the cubed up watermelon to the blender. You can see the blender will be full right up to the max line.
Next it’s time to blend the watermelon to make more room in the blender. You will have about 8 cups of watermelon pieces, and 5-6 cups of watermelon purée after blending.
Eight cups of watermelon is about 2.5 pounds. The watermelon that I bought weighed 18 pounds, so I’ll be making this everyday this week!
Finally blend until smooth and enjoy right away!

So glad you enjoyed it!
Another great watermelon recipe is making a pico de gallo salsa but instead of tomatoes substitute for watermelon. It is so delicious.
Sounds absolutely fantastic!
This is just what I was looking for. I’m in VA. And have been up since 3:30 thinking what to use with this watermelon. I’m headed to nearest store open for lemons. Want to make this now and share with my neighbor before she goes to work. Thanks Wanita
I sure hope you enjoy it, it’s definitely one of my favorites in the hot summer months!
Was a bit hesitant at first. However, this was a refreshing smoothie indeed! Thanks for sharing.
So glad you jumped in a tried it!
It’s funny reading about your strawberry watermelon smoothie. I just bought a quart of fresh strawberries and I blended what was left after everyone ate some with my watermelon. I added a little bit of milk to help the blender. It was delicious. I usually blend my watermelon by itself and drink it. I will try a banana to the strawberry and watermelon. It might be a little thicker because of the banana.
I’ve never tried banana before, but sometimes I freeze the watermelon too for a slushy effect!
Hi, how many calories in this smoothie???
I was also thinking of adding spinach & protein. Id like it to be my breakfast smoothie..
I don’t know the calorie count for this recipe, but you can look it up online and I’ll leave a link to a popular calorie calculator below. I’m not sure about making this into a breakfast smoothie as the beauty of this one is in the simplicity, so I can’t say how that might work out. But I do know that both watermelon and strawberries are lighter flavors and might be overwhelmed by the spinach and protein. I do have lots of green smoothies on the blog that might work better for that purpose, I’ll leave you a couple links below and there’s even more on the blog. The Berry Green Smoothie in particular would be a good choice for the protein breakfast smoothie. I hope this helps, and be sure to let me know if you have anymore questions! 🙂
