Jump to Recipe Print Recipe

This pineapple watermelon smoothie is a refreshing taste of summer! It’s got tropical vibes with just three ingredients – pineapple, watermelon, and banana.

Why you’ll love it:

I look forward to seasons of the year based on the fresh produce they bring. And nothing screams summer quite like a peak-season watermelon with it’s ruby red, juicy flesh.

This watermelon pineapple smoothie is ultra-refreshing, with a crisp, light flavor! And you only need three ingredients with no liquid base! Since watermelon is 92 percent water, it acts just like a liquid.

With notes of bright pineapple, sweet watermelon, and creamy banana, this watermelon pineapple smoothie is highly addictive and perfect for a day in the sun!

Key Ingredients:

frozen pineapple, watermelon, and banana.

Frozen pineapple – Be sure to use frozen pineapple! It’s what thickens the smoothie. If you use fresh pineapple, you will end up with pulpy juice!

Watermelon – The sweeter the watermelon, the better your smoothie! For best results, use a peak-season watermelon with a bright yellow field patch. If the ground spot is white or pale in color, it’s not ripe enough.

Banana – Use a yellow, ripe banana. Green bananas aren’t creamy or sweet enough.

How to Make a Watermelon Pineapple Smoothie:

Combine ingredients: In the pitcher of your blender, combine the banana, frozen pineapple, and watermelon chunks.

Blend: Blend until smooth and creamy. Check the consistency and adjust it if you like. It’s very easy to change the consistency.

If you want the smoothie thicker, add a few more pieces of frozen pineapple. If you want it thinner, add a few more pieces of watermelon. Blend again to incorporate.

Serve: Pour the pineapple and watermelon smoothie into a glass and enjoy immediately! Smoothies are best enjoyed fresh and frosty.

Recipe Tips:

Don’t add liquid. This smoothie recipe doesn’t need it! Watermelon is plenty juicy and turns into liquid when you blend it. If you add another liquid, the smoothie will be too thin.
Everyone prefers a different consistency. I typically prefer a thicker smoothie more than a thin one. Either way, it’s easy to adjust it to your preference. For a thicker consistency, add more frozen pineapple. For a thinner one, add more watermelon.
Add the watermelon before the frozen pineapple. Once you start the blender, the watermelon will turn to a liquid and cause all the ingredients to get moving.
This is a great recipe to use up leftover watermelon! After watermelon sits for a few days in the fridge, it gets a little mushy. I don’t prefer to eat it this way, but it works great for smoothies!

Health Benefits of Watermelon:

Not only is watermelon irresistibly juicy, it’s also full of feel-good nutrients! Here’s a few of my favorites:

Vitamins and minerals – It contains potassium, magnesium, plus vitamins A and C. Vitamin C is important for a healthy immune system, collagen formation, and the healing of wounds. Vitamin A helps make and repair skin cells!
Low-calorie – One cup of watermelon has only 46 calories. The reason? It’s full of hydrating water!
Lycopene – It’s filled with lycopene, a plant compound that may lower your risk of cancer, lower cholesterol, and lower your blood pressure.

Variations:

This watermelon smoothie is easy to customize! Just be sure not to add liquid, or else the smoothie will be too thin.

Raspberries – For a bright pink hue and sweet-tart flavor, swap 1/2 cup of the frozen pineapple with 1/2 cup of frozen raspberries.
Strawberries – Swap 1/2 cup of the frozen pineapple with frozen strawberries.
Yogurt – Add 1/3 cup of Greek yogurt for a boost of protein.
Chia seeds – Add one tablespoon of chia seeds for a boost of plant-based protein.

Storage:

I highly recommend enjoying this smoothie immediately! Technically you can store it in the refrigerator for up to 24 hours, but then it loses its thick, frosty texture.

If you have leftover smoothie, try making it into smoothie pops! Pour the smoothie into a popsicle mold, add popsicle sticks, and freeze overnight. My kiddos love smoothie pops!

No, you don’t need frozen watermelon! The fresh watermelon acts as a liquid base, allowing the smoothie to blend into a pourable consistency.
