Watermelon Smoothie, repeat. This is our summer song, our summer drink, and quite possibly the most refreshing recipe to ever grace my kitchen.

Two glasses of a creamy watermelon smoothie with strawberry and mint

A blend of frozen watermelon cubes, strawberries, and yogurt, with the optional addition of mint or basil if you feel so inclined, this pink drink is the grown-up equivalent of zipping down a Slip-n-Slide or drinking cold water right from the hose on the hottest day as a kid: utter exhilaration.

Ever since drinking Deb’s frozen watermelon mojitos last summer, I’ve been utterly enamored with freezing leftover watermelon to make drinks, this strawberry watermelon smoothie included.

(Note this is a regular watermelon smoothie recipe, but if you want to do a spinoff for a watermelon smoothie cocktail, I 100% support you.)

How to Make a Watermelon Smoothie

It can be tricky to make a watermelon smoothie without a recipe, because watermelon itself is nearly 92% water. That means that if you toss watermelon cubes into the blender, you’ll end up with watermelon juice.

The trick to making a luxuriously thick watermelon smoothie is to freeze the watermelon cubes first. From there, other ingredients can add different effects to the texture.

  • Personally, I love a creamy watermelon smoothie, so I took a note from my classic Strawberry Smoothie and Greek Yogurt Smoothie and added vanilla Greek yogurt. To die for.
  • The combo of the creamy yogurt with the frozen watermelon and strawberries reminded me of the cream slushes we used to order at the drive-in. (Sonic anyone?)
  • I prefer vanilla yogurt over plain yogurt in this recipe, as the vanilla adds necessary flavor and sweetness.
  • Another option to make the smoothie creamy and sweet is to add a fresh or frozen banana. Watermelon and banana go well together. Do note that if you add banana to this recipe, the banana’s flavor will be more pronounced.

What Fruit Goes Well with Watermelon

  • Watermelon goes well with a variety of fruits, including strawberries, bananas, and tropical fruits such as mango and pineapple.
  • The more frozen fruit you add, the thicker the smoothie will be.
  • My favorite fruit to pair with watermelon is strawberry. Because the strawberry’s flavor is complimentary and not overpowering, it allows the pure flavor of the watermelon to shine more than any other fruit pairing.

Adding Liquid

Since both the watermelon and the strawberries are frozen, you’ll need to add some liquid to help the smoothie blend. Here are a few options:

  • Regular Milk or Almond Milk. Use whatever you have around. I’ve used both to make the recipe and loved the results both times (it might sound weird, but in a smoothie, it’s fine to eat watermelon and milk together).
  • Coconut Water. For the ultimate refreshment.
  • Water. Yep, plain old water works just fine for smoothies.

Bonus Smoothie Additions

Spruce up your watermelon yogurt smoothie with any of the below:

  • Sweetener. Watermelon and strawberries can be bland in smoothies without the help of a little sweeter. I found ½ tablespoon of honey perfect for my taste, the ripeness of my melon, and the sweetness of my vanilla yogurt. You could also use agave. Pure maple syrup would be my last choice, as its flavor is a bit strong for the delicate melon.
  • Mint. SO REFRESHING. Making this a watermelon mint smoothie takes the recipe from “I’m at a beach and loving life” to “I’m at a beach resort and never leaving.”
  • Basil. More herbaceous, it’s another refreshing option.
  • Lime. For a watermelon mojito smoothie, add both mint and lime.
