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 are 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 way toward 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 too much. I like to blend the smoothie first, then add a few mint leaves at the end and blend only until little green bits remain.
Now let’s make this Strawberry Watermelon Smoothie recipe step by step
Step 1: First, we’ll start by removing the rind from the watermelon. I had some mini watermelons, so I cut all of 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.
Step 2: Cube up your watermelon. I like to keep the cubes small so I can fit more in the blender.
Step 3: Measure out the frozen strawberries, and juice the lemon or lime.
Step 4: Next, add the cubed-up watermelon to the blender. You can see the blender will be full right up to the max line.
Step 5: 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 every day this week!
Step 6: Finally, blend until smooth, and enjoy right away!

Throw a mint leaf in it!!
Yes, it’s so good with the mint thrown right in, but you do have to drink it quickly! 🙂
Love this. I found that freezing the watermelon as well as the strawberries makes a nice almost slushy drink that needs no ice to water it down. It’s definitely a summer favorite around my house. Thanks for the idea and the recipe!
I’m so glad you’ve enjoyed it! I like to freeze the watermelon too sometimes whenever I plan ahead because it’s so refreshing on a hot day.
This was delicious, thanks so much! I added a half of a frozen banana and a packet of Truvia. I made 1 serving so I started with 1 cup of watermelon.
I’m so glad you enjoyed it, and thanks for writing with your proportions for smaller servings, I know lots of people will benefit from that!
I am always looking for new ways to use watermelon. This looks fantastic. Yum!
I think you’ll love the next watermelon recipe then, it’s another drink and we take it everywhere with us in the summertime!

I cut the recipe down to just 1/6 of the original numbers for myself. It was AMAZING. Thanks for sharing!
Btw, I found this on the MSN Food and Drink App
Thanks so much Ethan, I originally made this recipe on a whim on a hot summer’s day with what I had available, and it’s become one of my all time favorites!
Wow! This is so good and refreshing . I made this for my daughter who just had braces put on. Her teeth are so sore and she only wants smoothies. She was very pleased when I gave this to her tonight! Thanks for the great recipe.
This smoothie really hits the spot every time the temperature soars! I’m so glad you and your family are enjoying it! 🙂
what lemon juice do you use? and how much?
I use 1/4 cup freshly squeezed lemon juice. I use a gadget called a reamer to juice my lemons but you can simply squeeze them by hand as well. Start by rolling the lemon under the palm of your hand, applying pressure to slightly soften the lemon. Next cut it in half and squeeze out the lemon juice, you can use a fork or the reamer I mentioned to make juicing the lemon easier. Hope this helps, and let me know if you have anymore questions!
This is so good! I added a little too much lemon juice but as I got deeper it got better
So glad you liked it! I make it quite a bit in the summertime because it’s so thirst quenching! 🙂
do the strawberries have to be frozen?
The strawberries don’t have to be frozen for this smoothie, but it’s best if they’re cold so that your smoothie won’t be warm. When they’re frozen they make kind of a slushy texture which is nice when the weather is hot.
