Whenever I buy a big bag of kale, my goal is simple: use every last leaf. That’s when I start freezing kale and getting creative with my green smoothies. This Kale Banana Smoothie is a great way to turn leftover kale into something crave-worthy.
It blends a mix of fruits—almost like a fruit salad—to soften kale’s bold flavor while still delivering plenty of fiber. I also add collagen to boost protein and support my body at this stage of life, because nourishing well now matters more than ever.

Kale Banana Smoothie Ingredients
- Kale: This leafy green vegetable is the nutrient backbone of the smoothie. It adds fiber, vitamin A, vitamin C, and antioxidants while blending smoothly when paired with enough liquid and fruit.
- Almond milk: A light, non-dairy milk that helps everything blend easily without overpowering the flavors. It keeps the smoothie creamy while staying low in calories. Check out the best almond milk brands to buy.
- Banana: Adds natural sweetness and a creamy texture that balances kale’s slightly bitter edge. It also contributes potassium for muscle and hydration support. You can also use frozen bananas.
- Frozen pineapple: Brings bright, tropical sweetness and a touch of acidity to keep the flavor fresh. Using it frozen helps create a cold, thick smoothie without ice. You can cut pineapple and freeze yourself, or buy it frozen.
- Frozen strawberries: Add natural sweetness, vitamin C, and antioxidants, plus a subtle berry flavor that pairs well with pineapple and banana.
- Collagen peptides: Boost protein content to make the smoothie more filling and supportive of muscle recovery. Using an unflavored option keeps the fruit flavors front and center.

Recipe Swaps
- Swap the kale with baby kale or spinach for a milder flavor that blends smoothly while still providing fiber and nutrients.
- Swap the almond milk with water, coconut water, or oat milk for a lighter texture or subtle sweetness.
- Swap the banana with ½ an avocado or frozen mango to keep the smoothie creamy with less natural sugar.
- Swap the collagen peptides with an unflavored protein powder to keep protein high without altering flavor.
How to Make Kale Banana Smoothie
- Start with the liquid. Pour the almond milk into your blender first. This helps everything blend more easily.
- Add the greens and soft fruit. Add the kale and banana next. Blending these first helps break down the kale so you don’t get leafy bits.
- Add frozen fruit. Toss in the frozen pineapple and strawberries for natural sweetness and a cold, thick texture.
- Finish with collagen. Add the collagen peptides last so they blend evenly.
- Blend until smooth. Start on low, then increase to high and blend until creamy. Add a splash more almond milk if needed.
Recipe Tips
Even though this smoothie is balanced and uses whole foods, the fruit can still be high in natural sugar. If you are sensitive to natural sugar, there are a variety of ways to help your body process those tasty sweet fruits:
- If you don’t have a smoothie blender, blend the kale and liquid first to fully break down the greens and create a smooth, grit-free base.
- Use frozen fruit instead of ice to keep the smoothie thick, cold, and naturally sweet without watering it down. Learn more ingredient tips in my how to make a smoothie guide.
- Balance the flavors with enough fruit or a squeeze of citrus to soften kale’s bitterness and keep the smoothie refreshing.
- Decrease sugar by swapping half the banana for a quarter of an avocado (or 1 whole banana with 1/2 an avocado). Your smoothie will be less sweet, but also lower in sugar.
If you’ve got extra kale after making this smoothie, don’t let it go to waste. Try blending it into other favorites like an tropical kale smoothie, mango kale smoothie or a refreshing coconut water smoothie for easy, flavorful ways to use it up.

- De-stem the kale before adding to your smoothie to cut down on the bitterness.
- Use at least one frozen fruit to make the smoothie cold or serve over ice.

Yes! Wash the kale well, and massage the leaves while you wash it (this tenderizes them). De-stem before adding to your blender to cut down on the bitterness.
Massaging kale is an easy way to cut down on bitterness. You can also pair kale with a citrus fruit (like pineapple or lemon) to counteract the bitterness.
It’s important to have a balanced smoothie, so swap the collagen with another protein source like protein powder, chia seeds or silken tofu.
Makes kale taste good. I would make it again!
So glad you enjoyed the kale! Thanks for the review!
This is a very creamy and mild smoothie. I would probably add more fruit to it next time because I like loud flavors, but this is a great smoothie for people starting out and looking to get more greens in their diet. It tasted great with my vanilla protein powder!
So glad you enjoyed the smoothie! Yes definitely bump up the fruit next time to make it work for you.
Couldn’t taste the kale just strawberry and banana.
The kale usually does not have a flavor in smoothies, which is a good thing. You can then enjoy the yumminess of the fruit.
I swapped avocado for banana because I can’t have banana. Another great smoothie. Feels healthy to drink.
Avocado is a great swap for a banana. You can still get the creaminess!
I really liked this one. I’m putting it on repeat. Thanks.
So glad you liked the smoothie! Thanks for the review!
Not a bad smoothie for Kale. The kale I chose was likely a little bitter because it came through on the taste. The banana helped considerably to sweeten the smoothy. I liked the almond milk for a little extra protein. I’ll make this again, but will try a different variety of kale, because it is sooo good for you. Very nutritious smoothy to keep in rotation.
So glad you liked the smoothie. Yes, try a different type to see what works best for your taste buds. Thanks for the review.
Kale yeah!!!
Yay kale! So glad you liked it!
Yum! Delicious smoothie all of these smoothies have delighted my taste buds.

Coconut water
Thank you, Marcia, for the review!
Delicious smoothie- It’s my go-to on most days. Today I used coconut water, kale and spinach, pineapple, strawberries, and Sunwarrior collagen protein powder.
So glad you have made this your own and it is on rotation!
I usually make my smoothies using water. I have made this smoothie with water and enjoyed it. Is there a reason yuo recommend using almond milk?
Water is always a winner, but almond milk does add a creaminess and also if you use my recommended almond milk brand, it also adds 5g protein in one 1 cup!
Great smoothie all the things I love in a smoothie, YUM
I am so glad you loved the smoothie!
All the things I love in a smoothie, great flavor
Yes! Glad you enjoyed the smoothie!
Much better than yesterday!! Very yummy

This Kale Banana Smoothie is one I am going to do on repeat! I like how all the ingredients come together! Also, I already had all the ingredients so that makes is so much easier.
It is always a win to have all the ingredients on hand. Glad you enjoyed the smoothie!
Always been a fan of Oh Kale Yeah! Very delicious and hits the spot.
So glad you liked the yummy kale smoothie!
Yummy. Previous so so experiences with kale in salads, smoothies and trying to crisp for a snack had me expecting this smoothie to be a so so. Pleasantly surprised. It’s delicious. Proportions make for a great blend. I did use protein powder in place of collagen and dairy milk as I have no issues with dairy.
PS. This was a good bunch of kale as I also actually enjoyed some in salads before freezing the rest for future smoothies.
Kale for the win! Glad you were surprised and delighted with this smoothie.
This smoothie is great. Love the addition of strawberries as that is not something I would normally pair with pineapple. I love greens and kale in smoothies and usually add more than what the recipe calls for. I only used 1/4 of a banana and added some frozen riced cauliflower to make it creamier. I also added vanilla protein powder in addition to the collagen to have this as a meal replacement.
Sounds like a yummy smoothie. I like how you added the riced cauliflower and more greens. More plants for the win!
Delicious. I love this combination of fruit with the kale.
Me too! So glad you loved the Kale Banana Smoothie!
