It’s easy to make this refreshingly sweet watermelon smoothie recipe that’s good and good for you. You only need 3 simple ingredients to whip up a batch of fruit smoothies in under 5 minutes!
Sommer’s Recipe Notes
It gets hot where we live in the south. Like, really hot. So as soon as the warm weather starts creeping up, the drinks get colder. At the pool, barbecues, and any outdoor gathering, something icy to sip on is a must-have.
Fresh and wonderfully frosty beverages are one of our favorite parts of summer. We’ve shared lots of tasty and easy recipes over the years for how to make all kinds of blended drinks… From Pina Coladas and Frozen Coconut Mojitos, to Frozen Lemonade with Pineapple and Pumpkin Pie Smoothies. If you’ve got a blender then you’re having fun in the summer!
Why You’ll Love This Easy Watermelon Smoothie Recipe
- 2 (but technically 3) Ingredients – This super simple recipe uses fresh watermelon plus strawberry yogurt for a creamy consistency and perfectly sweet fruity taste. And of course, since this is a smoothie we’re talking about, it also includes ice.
- A Lighter Frozen Treat – This recipe is great for making a low-calorie smoothie with no added sugar that adults and kids will love!
- Easy to Customize – Although there are only a few ingredients, there are SO many ways to make this recipe your own! Make it dairy-free and vegan, include other fruits, or even add a bit of alcohol for a boozy smoothie.
Bust out that blender and get ready to make batch after batch of these refreshing Watermelon Smoothies all season season!
3 Ingredients and Tips
- Fresh ripe watermelon cubes – Check out our guide for how to pick a watermelon and cut it into cubes! Keep in mind that frozen watermelon will make the thickest smoothies.
- Strawberry yogurt – Your choice of regular or low fat flavored yogurt.
- Ice – For a thick and frosty blended watermelon smoothie.
Also, sugar is optional depending on the level of sweetness your fresh watermelon is. If you select a good watermelon in season, you shouldn’t need it.
Recipe Variations and Dietary Swaps
- Fruit – Substitute half of the watermelon cubes for other fruits, like frozen strawberries, pineapple or mango.
- Yogurt – You can use “plain” vanilla yogurt to cut out any strawberry flavor.
- Nondairy – Swap traditional yogurt with your favorite dairy-free alternative.
- With Alcohol – Feel free to prepare this recipe as an adults-only boozy treat by adding 4 oz of vodka or rum while blending.
How to Make a Creamy Watermelon Smoothie
Tips for Success – Make sure to get out all of the dark brown seeds from the watermelon cubes before blending. The little white seeds are fine left in. (Buy a seedless watermelon to make it easy!)
Also, don’t throw away that rind! You can use it to make an amazing Pickled Watermelon recipe. You’re welcome :)

Serving Suggestions
Add a slice or cube of watermelon, or sliced strawberry, to the rim of each glass to garnish. Some fresh mint leaves are also lovely for a pop of flavor!
You definitely want to serve these immediately while the smoothie is ice cold.
Frequently Asked Questions
Coconut milk makes a great alternative to yogurt in this recipe. For a thick smoothie use thin coconut milk or oat creamer; or for a thicker, creamier drink use canned coconut cream or cashew cream.
Flash freeze the watermelon cubes on a baking sheet before blending with the strawberry yogurt. You can add a bit more ice, too. However, keep in mind that if you add a whole lot more ice, this will dilute the luscious watermelon and strawberry flavors.
Yes and yes! As-is this recipe makes 4 generous servings. Reduce the ingredients by half to make Watermelon Smoothies for two, or double (or triple!) the recipe for a party. You’ll just likely have to make it in several blender batches. Use the handy “serving slider” in the recipe form below to help.
No, it really is best to enjoy frosty blended fruit smoothie soon after they are made. Once the ice starts to melt the drink will become soupy, which is the opposite of what you want!
