The Best Healthiest Watermelon Smoothie Recipe

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 Coconut Choco Chai Smoothies. If you’ve got a blender then you’re having fun in the summer!

And, considering that we tend to make a lot of these slushy beverages throughout the season, we thought we should make a cold treat that is delicious and healthy.

This super simple and light Watermelon Smoothie recipe requires only 2 ingredients and ice! We use fresh watermelon plus strawberry yogurt for a creamy consistency and perfectly sweet fruity taste. It’s great for making low-calorie smoothies with no added sugar that adults and kids will love!

Bust out that blender and make a batch of these refreshing Watermelon Smoothies this season.

How to Make a Watermelon Smoothie in 3 Easy Steps

First, make sure to get out all of the dark brown seeds from the watermelon cubes. The little white seeds are fine left in. (Buy a seedless watermelon to make it easy!) Then place the watermelon cubes and yogurt in the blender.

Frequently Asked Questions

How can I garnish Watermelon Smoothies?

Add a slice or cube of watermelon, or sliced strawberry, to the rim of each glass. Some fresh mint leaves are also lovely for a pop of flavor!

What can I use to make a Watermelon Smoothie without yogurt?

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.

How do I make this an even thicker smoothie?

Flash freeze the watermelon cubes 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.

Can I make Watermelon Smoothie with alcohol?

Absolutely! Feel free to prepare this recipe as an adults-only boozy treat by adding 4 oz of vodka or rum while blending.

Can this recipe be doubled? Halved?

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.
