Wonderful Watermelon Smoothie Recipe

One of our favorite things about summer is the fact that watermelon comes into season! Whether we’re making pineapple watermelon salsa or snacking on it on its own, we can’t get enough.

So, when the heat began to soar, it seemed to make sense for us to add it to a smoothie. The best way to cool off on a hot day, this watermelon smoothie recipe is sweet, creamy, and perfectly refreshing. Whip it up in minutes for a snack the whole family will enjoy!

What Fruit Mixes Well with Watermelon?

To be honest, there’s not much that doesn’t go well with watermelon! For instance, it tastes great with strawberries, banana, mango, pineapple, cherries, blueberries, raspberries, blackberries, peaches, plums, cantaloupe, honeydew, orange, pomegranate, apples, grapes, pears, grapefruit, and kiwi.

However, when it comes to making a smoothie, we’ve found that sweeter fruits like strawberries and bananas taste best.

5 Basic Ingredients and Optional Mix-Ins

For this watermelon smoothie recipe, we kept the ingredient list short and sweet, letting the sweet flavor of the fruit speak for itself. Here’s what you’ll need:

Frozen watermelon, halved strawberries and banana coins on a white cutting board.

Watermelon – You can’t have a watermelon smoothie without watermelon! Use frozen chunks for the best consistency.
Banana – Opt for bananas that are ripe but not too ripe, because we want the benefits of resistant starch.
Strawberries – These help add extra depth to the flavor while enhancing the pink color of the drink and adding lots of fiber.

Nutrition Note: Not only are they delicious, but bananas and strawberries both provide a significant source of potassium to help replenish electrolyte levels. In addition, the strawberries help keep you hydrated, given that they’re 90% water!

Non-Dairy Milk – Any dairy-free milk like almond milk, oat milk, or hemp milk can be used.
Fresh Mint Leaves – A little goes a long way to add a refreshing taste while also aiding digestion and providing anti-inflammatory benefits.

Ingredient Swap: Some people like to use basil instead of mint for a slightly more herbaceous taste!

Sea Salt – This ingredient might sound strange, but trust us. It enhances the flavor of the rest of the ingredients, making your smoothie even more delicious. Plus, it helps replenish sodium levels!
Optional Mix-Ins – If you’re feeling fancy, feel free to go the extra mile with the addition of regular vanilla yogurt, plain or vanilla Greek yogurt or coconut milk yogurt for a boost of protein and calcium, chia seeds, protein powder or collagen, a pinch cinnamon, spinach, honey, or maple syrup.

Note: The more frozen fruit you use, the thicker your smoothie will be (and the more liquid you’ll need).

Health Benefits of Watermelon

You probably already know this, but watermelon isn’t just delicious, it’s also loaded with health benefits, too! For instance, watermelon is:

A good source of vitamin A and vitamin C.
Rich in potassium and magnesium.
Full of antioxidants.
Low in calories and carbohydrates.
Great for hydration.

How to Cut a Watermelon for Smoothies

The best way to cut a watermelon for smoothies is to slice it into watermelon chunks! Take a look at the instructions to do so:

Fresh watermelon wedges stacked on top of each other on a white countertop.

Cut off both sides to create flat ends.
Run a knife down the sides of the fruit, following its natural shape to cut off the rind and white parts.
Next, make vertical slices. Then, slice horizontally to create watermelon cubes, and you’re done!

How to Make a Watermelon Smoothie

Combine. Add all the ingredients to the bowl of a high-speed blender, and pulse until smooth.
Adjust. Give your smoothie a taste test, adjust the ingredients as needed, adding more honey or agave syrup for extra sweetness as needed. Serve immediately!

Pro-Tip: Allow plenty of time for your fruit to chill and harden in the freezer. Otherwise, your smoothie is likely to turn out runny!

Make Ahead and Storage Tips

This watermelon smoothie recipe is best enjoyed right away. However, it can also be stored for later if you want to prepare in advance.

To Store: Transfer the smoothie to an airtight container, and keep it stored in the fridge for up to 2 days.
To Freeze: Blend the watermelon smoothie. Then, pour it into an ice cube mold, and transfer it to a freezer. Once frozen, place the cubes in a sealable bag, and keep them stored for up to 3 months. To enjoy, let them thaw in the fridge overnight. Or, add the cubes back to the blender with a little extra milk, and blend away!

Common Questions About This Watermelon Smoothie Recipe

What can I do with the leftover watermelon rind?

Don’t toss it out! Watermelon rind is actually full of nutrients and can be used in smoothies, pickled, turned into candy, added to a stir fry, and more.

Can I use coconut water?

Sure! You may need to adjust the amount, and the flavor of your smoothie will change. But it will still taste great.

Does my watermelon have to be frozen?

We recommend using frozen watermelon, but you don’t have to. Your smoothie will just have a more runny texture.

Do I need to add ice cubes to this recipe?

Nope! As long as your fruit is frozen, there is no need for ice cubes to thicken it.
