Not one, but TWO leafy greens are represented into this tasty green smoothie! So, if you are on a mission to get more vegetables into your diet and belly, this kale and spinach smoothie is a great recipe to get you started.

I’m a big fan of fruit and veggie smoothie recipes. They are how I got going veggie-loading my own life years ago. Because they are quick, simple, and delicious, adding smoothies to our family’s routine was a sustainable step that lead to more veggie-loading in many other ways. And because of how easy and nutrient-dense a vegetable-packed smoothie can be, they remain one of my go-to fast foods for when life gets busy. And I am extra into the goodness of the 5-Minute Kale and Spinach Smoothie.

Because it can be made with frozen or fresh greens and/or fruit, this Kale Spinach Smoothie is one that can be made year round. Not only is this smoothie rocking the fiber and vitamins of kale, spinach, mango, and banana, but it has a boost of protein from Greek yogurt and peanut butter. Like all of my easy smoothie recipes, this blend can easily be adapted to fit your needs and personal tastes with a few tweaks. However it is naturally gluten free and vegetarian as is!

Steps for making the perfect green smoothie

  1. Add the liquid to the blender first followed by the spinach and kale. Blend this first so that the greens easily get pureed and are nice and smooth.
  2. Then add the mango and banana to the smoothie and blend again! This will help you to not end up with an unexpected chunk of veggie in a sip of smoothie.
  3. Adjust the amount of ice and liquid to achieve your desired consistency.
  4. Don’t be afraid of add-ins! I love adding ground flax or chia seeds to this smoothie. Don’t be afraid to make this kale and spinach smoothie your own.

Suggested Adaptations

  • Use frozen spinach and kale. Leafy greens wilt down considerably in volume during the freezing process, so you will need to reduce the amount of frozen kale and frozen spinach you use. I’d suggest about 1/2 cup each if using frozen.
  • Use frozen banana. Just leave a little add more milk or a splash of water so that the spinach smoothie belnds easily.
  • Make it dairy-free & vegan by subbing the yogurt with silken tofu or plant based yogurt and the milk with dairy-free yogurt.
  • Throw in some add-ins! Like chia seeds, hemp seeds, flax seeds, protein powder, or honey.
  • Omit the peanut butter or sub with sunflower seed butter to make this smoothie nut-free.
