Watermelon Protein Smoothie

When it’s hot outside, a protein smoothie is a wonderful way to get essential nutrients and of course your protein in a light and refreshing way.

Which is why I created this watermelon protein smoothie. As a bonus, it requires no protein powder!

Why You Will Love This Watermelon Protein Smoothie

While the obvious reason is that the smoothie is incredibly refreshing and tasty, thanks to the watermelon, but this smoothie has so much more to offer than that.

Here’s an overview:

  1. Hydration: Watermelon is very high in water content, which helps hydrate the body effectively.
  2. Protein Rich: Greek yogurt provides a substantial amount of protein without the need for protein powder. A serving of this smoothie contains 26g of protein.
  3. Energy Boosting: The natural sugars from bananas and honey provide a quick energy boost, making it a great option for a morning or afternoon pick-me-up.
  4. Digestive Health: The fiber in bananas enhances digestive efficiency, while Greek yogurt’s probiotics support gut health.
  5. Rich in Vitamins and Minerals: Provides important nutrients such as potassium from bananas, Vitamin C from watermelon, and various B vitamins from yogurt.
  6. Low Fat and Heart Healthy: This smoothie is relatively low in fat, and the fats present are mostly healthy ones from almond milk and yogurt.

I recommend that you also try my other no protein powder smoothie and my watermelon smoothie bowl recipe!

Watermelon Protein Shake Recipe Customizations

If the ingredients used to make this watermelon protein smoothie are not to your liking, here are some alternative ingredients and add-ons you can use to make this beverage:

  • For a watermelon vanilla protein shake, you have two options; add a touch of vanilla extract to your blender, or use vanilla-flavored protein powder.
  • Instead of a banana, you can use mango or pineapple; both of these tropical fruits work wonderfully with watermelon!
  • For an increased nutrient density, you can add 1/2 cup of frozen berries, which will create a more colorful smoothie, but also enhance the vitamin content of this shake.
  • If you like extra thick smoothies, you can use frozen watermelon and frozen bananas.
  • For a dairy-free option, use oat or almond milk, instead of dairy milk.

Storing The Smoothie

I have personally only ever tried storing this type of smoothie for 24 hours.

And to be honest, it tasted fine. The texture was impacted slightly, but other than that, it was fine.

To store it properly, transfer the blender smoothie into a mason jar, a portable gym bottle, or an airt-tight container, and refrigerate.
