This tasty watermelon spinach smoothie has many health benefits like many green smoothies do

This green smoothie with watermelon is vegan and gives you 4 out of your 5 a day in one drink!

Here are some of the main benefits of drinking this delicious watermelon veggie smoothie:

  • Nutrient-Rich: This smoothie is packed with essential vitamins and minerals that contribute to overall wellness. The use of multiple different superfoods in this smoothie creates a very nutrient-dense smoothie.
  • Antioxidants: Ingredients like spinach and watermelon contain antioxidants, which can help fight free radicals in the body.
  • Alkalizing: The use of lime and cucumber in this smoothie has alkalizing effects, which can help balance your body’s pH levels.
  • Skin Health: The vitamins and antioxidants in the ingredients can contribute to glowing, healthy skin.
  • Energy Boosting: The natural sugars and nutrients can provide a great source of energy, ideal for kickstarting your day or refueling post-exercise.

Recipe Variations

Now, I want to leave room for you to make changes that fit your taste or the ingredients available to you right now at your home.

  • For a berry version, you can add 1/2 cup fresh or frozen berries of choice to your blender along with the other ingredients listed.
  • If you don’t like or have avocado, you can use mango, or pineapple instead of avocado. For a low-sugar avocado substitute, use 1/2 cup of Greek yogurt.
  • The spinach can be substituted for kale or other leafy greens you like more.
  • You can also use frozen watermelon pieces if you like thicker smoothies.

Blender Compatibility 

Blender Type Suitability
Nutribullet 600
Vitamix Blender Propel 510
BlendJet 4000mAh x
Ninja Blender BL610
Oster 6640 Blender
Hamilton Beach 58148A Blender
AMZChef Blender 1800 W
Wamife Blender

The smoothie is blended easily with most blenders. I tested the smoothie with 8 different blenders.

Only the BlendJet 4000mAh didn’t do a particularly good job, so I suggest you avoid it for this recipe.

Storing The Smoothie

This smoothie doesn’t store very well. It’s because it combines frozen fruit, but most importantly, it contains watery fruit (the watermelon).

I did an experiment recently where tested how long smoothies last in the fridge, and the melon smoothie didn’t last long.

So I recommend that you consume this smoothie within 3-6 hours. Just make sure you refrigerate it as soon as it’s blended though!
