I’m just not sure where it has been all my life!

Here’s how they came to be. You see, I’m still working my way through that watermelon that I shared the story about for my Watermelon Salad with Watermelon Vinaigrette and then again with the Watermelon Feta Appetizer Bites. I texted my husband to see what he wanted for lunch and he said, “it is so hot, I really just want a smoothie.”

Bingo. I knew just the perfect new smoothie recipe to whip up for him. What’s more refreshing than a juicy watermelon. Right?

So, I tossed a bunch of blueberries and watermelon chunks into my blender, gave it a whirl, and then added in some ice to smooth things out even more.

No fancy straws needed for this smoothie either. I knew the Mister has no use for them and these smoothies really were so beautiful without adding any other sort of frills to them.

  1. 5 stars
    Thank you so much Robin for the idea. I have tried it…It was sooo refreshing…I added some strawberries and some chia seeds as well…even more refreshing. Will do it again.

  2. Loving my new blender and can’t wait to try this while I still can before the melon is all gone. I made a watermelon kiwi one the other day from a cookbook and loved it. Thanks for sharing, I see you have a peach one too.. I am happy as you aren’t slipping bananas into them as I can’t eat those. Thank you!

  3. Looks like this frothy bluish red smoothie is gonna be my new obsession for Summertime 🙂 Cool images. Literally 🙂

  4. I love this! We just went blueberry picking last weekend so now I’m trying to find different ways to use them. My son loves smoothies and I think this will be a perfect summer treat for us!

  5. Watermelon in a smoothie?! Um, I friggin’ love this idea!!! Can’t wait to try this.
