Smoothies are a great way to pack nutrients into a sweet, creamy, almost dessert-like format. However, there’s no need to rely on super-long ingredient lists and expensive superfoods to do so. Sometimes it’s as simple as sneaking in just one nutrient-rich green, like in this easy banana kale smoothie recipe.

With a base of just three ingredients, this simple kale smoothie recipe uses frozen bananas for a super simple smoothie that tastes like a banana ice-cream milkshake (and, more importantly, NOT of kale). However, it’s also super simple to prepare, ready in minutes, and very budget-friendly, for a ‘healthy habit’ that won’t feel like work to keep up.

The natural sweetness of the bananas not only masks the kale flavor but means no added sugars are necessary for a super satisfyingly thick, sweet, and creamy banana green smoothie loaded with fiber, micronutrients, and antioxidants.

This simple kale smoothie recipe leaves plenty of room for experimentation, too. So, not only is it great already, but you can easily boost the flavor and nutrients (including extra fiber, protein, healthy fats, etc.) with ingredients already in your freezer/pantry. You might also enjoy our recipes for a Strawberry Kale Smoothie and Kale Pineapple Smoothie as a simple nutrient-dense breakfast or mid-day pick-me-up!

The Benefits of Kale Smoothie With Bananas

Kale is one of the most nutrient-dense foods in the world. It’s packed with fiber and antioxidants. It contains no fat and few calories, but is a rich source of several micro-nutrients. That includes almost 70% of your daily recommended vitamin K in a single cup, more vitamin C than an orange, manganese, vitamin A, and calcium.

Meanwhile, bananas also contain plenty of fiber and antioxidants. They are also a rich source of potassium, vitamin B6, and vitamin C. Combined, this smoothie benefits blood clotting, blood pressure levels, heart health, gut health, and the immune system. It’s also anti-inflammatory and detoxifying!

The Ingredients

ingredients for Banana Kale Smoothie measured out against a white background
  • Banana: It’s best to use frozen, slightly overripe bananas for their natural sweetness and ability to make a wonderfully thick and creamy smoothie. However, use fresh ripe bananas if preferred.

You could also substitute some or all the banana with frozen mango or pineapple. To lower the natural sugars in the smoothie, replace one banana with ½ an avocado or about ½-¾ cup frozen cauliflower instead.

  • Kale: Use any raw kale (baby kale has the mildest flavor) with the thick stems removed. Spinach or a combination of the two would also work.
  • Plant-based milk: You can use any dairy-free milk based on your desired creaminess and flavor. I.e., almond milk, cashew milk, oat milk, soy milk, etc. For more flavor, use juice instead, like orange juice, apple juice, or pineapple juice.

We find the bananas are often sweet enough for us. However, if not, you could add extra sweetener in the form of 1-2 Medjool dates, maple syrup, agave, or a sugar-free sweetener like swerve/erythritol.

What Could I Add To A Kale Smoothie?

We love the simplicity of this banana kale smoothie, but that also lends itself to versatility. Here are a few of our top favorite add-ins.

  • Vanilla extract: ½-1 tsp for extra dessert-like flavor.
  • Ginger: Add minced ginger (½ tsp) or ginger powder (a pinch) for a zingy flavor.
  • Vegan yogurt: Replace some plant-based milk with dairy-free yogurt for a thicker, creamier kale and banana smoothie.
  • Other fruits: One of the easiest ways to add flavor and disguise veggies is extra fruit (replace 1 banana with ½-¾ cup of other fruit). This kale smoothie pairs particularly with mango, pineapple, peaches, strawberry, blueberry, and mixed berries.
  • Seed/Nut butter: Add 1 tbsp of peanut butter, almond butter, sunflower seed butter, etc., for added rich flavor plus heart-healthy fats, fiber, and protein.
  • Vegan protein powder: Add 1 scoop of unflavored, vanilla, or fruity protein powder for a kale protein smoothie.
  • Oats: ¼ cup of rolled oats adds a ton of fiber for a super-filling breakfast banana green smoothie.
  • Ground seeds: Add 1 tbsp ground flaxseed, chia seeds, or hemp seeds for added fiber, plant-based protein, and heart-healthy omega-3 fatty acids.

How to Make a Banana Kale Smoothie?

  • 1) Add all the ingredients to a high-speed blender (liquid and soft ingredients closest to the blade) and process until smooth and creamy.

  • 2) Transfer the banana kale smoothie to a glass, optionally top it with any toppings, and enjoy!

If using a low-powered/old blender, you may need to give the machine breaks to scrape down the sides. Allowing the bananas 10 minutes to thaw before blending may help, too.

Top Tips For The Best Results

  • Adjust the consistency: For a thinner smoothie, add more plant-based milk. For a thicker one, add some ice cubes.
  • If using a weak blender: Always add the soft/liquid ingredients first and use small, frozen chopped banana pieces to make them easier to blend. Fresh banana also works but isn’t as decadent/as nice cream, like.
  • Tweak to taste: Experiment with various add-ins. For example, pair the base recipe with some ground seed or nut/seed butter with another type of fruit to boost the nutrients further. This will increase the fiber, protein, micronutrients, and antioxidants in this recipe for kale smoothie.
  • Sweeten to taste: The bananas may be sweet enough, but if not, add your favorite natural sweetener to taste.

Storage Instructions

We always have a stash of frozen bananas and other fruits in the freezer for last-minute smoothie (and nice cream) needs. However, you can also prepare individual ziplock bags with the portioned banana and kale to transfer to the blender each morning with plant-based milk.

It’s best to consume the frozen kale smoothie immediately after making it. If using fresh bananas, you can store any leftovers in an airtight container in the fridge for up to a day (best within 4-5 hours), shaking it well before drinking.

You can also freeze leftover smoothie in Ziplock/Stasher bags (spread thin, excess air squeezed out) for up to 3 months. Leave it to thaw in the fridge overnight before shaking/stirring well to enjoy.

Alternatively, you can also use the leftovers to pour into popsicle molds as a simple, healthy frozen treat!

  1. 5 stars
    I’ve been making a version of this for quite awhile and love it! I add frozen wild blueberries too.

  2. Love the creaminess and flavors of this smoothie. I added 1 date for a touch a sweetness, a spoonful of almond butter for added protein, and a dash of cinnamon for flavor. Nutritious AND delicious!

  3. Made this with my family for St. Patrick’s day. All three boys drank their smoothie without complaint. Yummy 🙂 I may add avocado next time to some healthy fats!

  4. This is the first time I’ve had Kale. I was worried it was going to over power the banana somehow but this is delicious!

  5. 5 stars
    Saw this on my instagram, and made it that morning. Added a scoop of AG greens and a touch of raw honey and cinnamon. Delicious!

  6. So easy and nutritious. The bananas are so naturally sweet, the smoothie doesn’t need any nudges from added sweetener.

  7. 5 stars
    This is soo good! So simple and easy to make!

    I’m vegetarian, not vegan, so I used regular milk instead of plant-based and it came out like ice cream! It was so delicious topped with granola

  8. This smoothie is a healthy start! I love healthy options and this is a great way to include kale in the diet.
