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.

    This one was fine, but not my favorite. I think it hinges on using really tasty watermelon, which is a rarity in finding for me.

    I am one day late for rating this watermelon smoothie. I actually made this one in the afternoon. It was a warm day and I decided to make this instead of going for the diet coke. It was so refreshing! I had purchased frozen cherries before the challenge and it made all the difference for this smoothie. DE-Lish-ous! This will be my new summertime drink and I can make ice pops when the grandbabies come for a visit in July!

    I’m not a big fan of melons in my smoothies. It wasn’t bad just not my favorite. I almost always add chia seeds to my smoothies.

    I loved this smoothie. It wasn’t too sweet or too tart. I like that is was made with whole fruits and nothing else. Very healthy and refreshing!!

  5. This was ok to me, a little gritty. It wasn’t my favorite, but I still like them!

    This is one refreshing drink! I wonder what it would taste like with a spark of rum. I’m going to fine out on my next just chill day with the ladies

    I can’t think of any more apt description other than refreshing. This had a perfect blend of sweet and tart from the cherries and lime and just sweet from the strawberries and watermelon. It was a perfect pick-me-up afternoon snack for summer camp pick up.

    Very refreshing, but not what I’d make often for myself. I thought it was too sweet.

    Fantastic. My husband says best smoothie he has ever had. Plan to make again and freeze for shaved ice.

    This is a great way to use up my overripe watermelon. I made several batches with slight variations. As it is written is very good. I like to go light on the lime; with just enough to add a touch of acid. I also went heavy on the lime with one and got into the margarita territory. That was okay. I tried some with vanilla whey protein added, and others with no added protein. I prefer the icy fruit drink without any protein powder. But really, if you are like me and not too worried about sugar, it’s hard to beat any sort of fruit smoothie.
