Tasty Kale and Spinach Green Smoothie (With Avocado and Fruits)

Last updated: August 13, 2023

A creamy and nutritious kale, spinach, and avocado green smoothie recipe, mixed with fresh fruit, for a refreshing energy boost.

Kale and spinach are two of my favorite vegetables to add to my smoothie recipes, because of their strong nutritional benefits but also because of their somewhat neutral flavors. When you combine these two together and mix them up with avocado and fresh fruit, you will end up with a super nutritious and very green-looking smoothie.

This particular kale and spinach green smoothie recipe is one of my go-to drinks that I like to prepare whenever I need a healthy energy boost!

Please find the printable version of this recipe further below.


With kale, spinach, and avocado as the core ingredients, this green smoothie can’t get much greener and more nutritious.

Here’s the complete list of goodies that go into this smoothie.



  • 50 grams (or 1 large cup) kale
  • 50 grams baby spinach
  • 1/2 avocado
  • 1 large banana (fresh or frozen)
  • 4 strawberries (optional)
  • water + ice cubes


This kale smoothie offers a welcome balance between vegetables and fruits, delivering a taste that is very refreshing and not too “green”.

Unsurprisingly, kale offers powerful benefits, which is the main reason for me to often use kale in my smoothies, alongside spinach and other leafy greens.

Cutting fresh kale

Drink this in the morning as a healthy wake-me-up breakfast smoothie, or in the afternoon to fight that unwanted 3 pm afternoon energy crash.

You can add as much water and ice cubes as you wish, depending on how thick you would like this smoothie to be.

Keep in mind though that avocados do thicken smoothies quite a fair bit, so it’s a good idea to be generous with the water.

Fresh spinach in bowl

You could also consider adding some watermelon because that has a high water content. Personally, I prefer my smoothies not too sweet, but that’s ultimately a personal preference.

What’s also a good idea is to add some flax seeds or chia seeds to make this smoothie even more nutritious. And add a bit of lemon juice if you would like a somewhat sharper taste.

Avocado cut in two

Oh, and did you know you can also blend the seed of an avocado? Check out my avocado seed smoothie recipe for more details!
