5 Watermelon Smoothie Tips

  1. Since watermelon is over 90% water by weight, you don’t need to add any extra liquid or ice to this smoothie.
  2. Use seedless watermelon for this recipe. No need to spend all day picking out watermelon seeds!
  3. Using frozen cherries and frozen strawberries rather than fresh ones yields a cool and frosty drink. If using fresh, add ice cubes to the blender.
  4. Serve this smoothie immediately after making it. The longer it sits, the more the watermelon separates from the other ingredients.
  5. Want popsicles? Freeze the smoothie in freezer pop molds to make homemade popsicles for the kids.

Health Benefits of a Summer Smoothie

Summer is overflowing with nutrient-dense produce. Take advantage of these ruby red, antioxidant-rich ingredients!


Watermelon has high water content, so it’s the perfect fruit for hydration. All that water doesn’t mean it’s lacking in powerful antioxidants. Watermelon actually has about 40% more lycopene than raw tomatoes. Lycopene can help curb your risk of cancer and heart disease as well as offers some protective effects against damaging UV rays.


Strawberries add filling fiber to this watermelon smoothie as well as vitamin C and other beneficial antioxidants. Blood sugar regulation, reducing heart disease risk and boosting immunity are just some of the health benefits of adding strawberries to your diet.


Cherries are also high in fiber and loaded with antioxidants. These powerful antioxidants may protect against cancer, cardiovascular disease and diabetes as well as Alzheimer’s. Anti-inflammatory compounds in cherries may help reduce muscle pain and damage.

Watermelon Smoothie FAQs

What fruit mixes well with watermelon?

My watermelon smoothie blends cherries, watermelon, strawberries and lime. It’s super refreshing and antioxidant-loaded!

Is it okay to blend watermelon?

Yes! When using any kind of melon in a smoothie, I cut back on the amount of liquid. Watermelon contains enough water on its own that you don’t need any more liquid. Also, don’t forget to remove the seeds!

Can I freeze watermelon?

Watermelon acts as both the liquid and fruit in a smoothie. If you freeze the watermelon, be sure to add extra liquid to help it blend well.

  1. I liked this smoothly, it was refreshing and felt like summer please remember to freeze as much of the fruit a couple of hours before blending as it has a tendency to become Waterloo soon after blending.

    Wow! This smoothie is the ultimate refresher! It’s like having sherbert for breakfast! I love, love, love it!❤❤❤. I didn’t have cherries, so used blueberries. Added and blended in the chia (instead of using it to top off) and added a scoop of plant based vanilla protein powder.

      Delicious, but I don’t want it for breakfast! Feels like a sugar bomb. Would love to sip on it in the evening on the porch. I took a taste, put it in the fridge and made myself something a little greener for breakfast!

  3. Thanks so much for sharing this recipe! I love watermelon and this turned out to be a really refreshing treat!

    I suggest liquifying the watermelon and slowly adding the frozen fruit into the instructions.

    Lovely and super refreshing! Starting the summer smoothie challenge early because I had a lot of leftover watermelon from Memorial Day weekend. This is simply wonderful flavors! Might be my favorite!! Mint would be a nice addition I think. Would love to make this after a hot day working in the yard!

    Have you tried yellow watermelon? I’m growing that in my garden and wonder what it would be like in a smoothie!
