This spinach banana smoothie has been a longtime favorite in my kitchen, but I recently decided to give it a little glow-up. I reworked the recipe to boost fiber, increase protein, and layer in even more flavor—turning it from a light, refreshing blend into a more balanced meal replacement. It’s still just as bright and creamy as ever, but now it keeps you full, fueled, and satisfied for hours.

Label ingredients for making spinach banana smoothie.

Ingredients You’ll Need

What I love most about this smoothie is how customizable it is. You can keep it light and refreshing, or turn it into a hearty, stay-full meal with simple add-ins like protein powder, nut butters, seeds, or oats. One sip in, and you’ll understand why this blend delivers a serious happiness boost.

  • Fresh spinach: A mild leafy green that adds fiber, iron, and vitamin A without overpowering the flavor.
  • Orange (peeled): Bright, juicy citrus that brings natural sweetness, vitamin C, and liquid for easy blending.
  • Banana: The natural sweetener and cream-maker that balances the citrus and thickens the smoothie.
  • Frozen cauliflower florets: A freezer-friendly secret for extra creaminess and fiber with zero veggie taste.
  • Chilled coconut milk: Adds healthy fats and a light tropical richness for a smooth, satisfying texture. Check out my recommended coconut milk brands to help you shop. If you’re not a fan of coconut milk, swap with my recommended almond milk brands.
  • Homemade protein powder (optional): Helps turn this smoothie into a filling breakfast or post-workout meal.

How to Make a Spinach Banana Smoothie

This spinach banana smoothie comes together fast, but using a high-speed blender makes all the difference. Oranges have stringy membranes and spinach is fibrous, so powerful smoothie blenders help create a smooth, creamy texture without pulp or grit.

  1. Add your base ingredients. Add spinach, peeled orange, banana, frozen cauliflower, and chilled coconut milk to your blender. You can also make coconut milk at home.
  2. Blend until creamy. Start on low, then increase to high until completely smooth. Stop and scrape the sides if needed.
  3. Optional protein boost. Add protein powder and blend briefly, just until combined.
  4. Serve right away. Pour into a glass and enjoy immediately for the best flavor and texture.

Recipe Tip

Stocking your freezer is the secret to thick, creamy smoothies—no ice required. Keeping frozen meal prep smoothie packs on hand means this smoothie is always just minutes away.

  • Frozen cauliflower: I love using frozen riced cauliflower from Costco. It blends smoothly and adds creaminess without any veggie flavor.
  • Frozen bananas: Peel, slice, and freeze ripe bananas for natural sweetness and a creamy texture following my how to freeze bananas tutorial.
  • Frozen spinach: You can freeze spinach in handfuls or into cubes for an easy greens boost.

Suggested Mix-Ins

Whether you keep it simple or load it up with boosts, this spinach banana smoothie proves that green smoothies can be creamy, comforting, and totally crave-worthy. Blend it once, and you’ll find yourself coming back to it again and again.

  • Add nut butter: Peanut butter, almond butter, or cashew butter add healthy fats and make the smoothie extra satisfying. Peanut butter pairs especially well with banana and orange.
  • Sprinkle in seeds: Flaxseeds, chia seeds and hemp seeds add fiber, omega-3s, and plant-based protein without changing the flavor much. Ground flaxseed blends best.
  • Warm it up with spices: Cinnamon adds cozy sweetness without sugar, while fresh or ground ginger brings a zingy kick that supports digestion and immunity.
  • Sneak in more veggies: Frozen zucchini, extra cauliflower, or a handful of frozen spinach work beautifully and keep the texture creamy.
  • Make it extra filling: Rolled oats turn this smoothie into a stick-to-your-ribs breakfast. Start small and add more if needed.

Common Questions

Will the spinach banana smoothie taste like spinach?

Nope. Spinach has a very mild flavor, and in this spinach banana smoothie it’s completely balanced by sweet banana and bright orange.

Do I need a high-speed blender to make this smoothie?

A high-speed blender gives the creamiest spinach banana smoothie, especially since oranges have fibrous membranes. A standard blender works too, though the texture may be slightly pulpy.

Can I use a different milk in this spinach banana smoothie?

Yes. Almond milk, oat milk, soy milk, or cashew milk all work well in a spinach banana smoothie if you don’t have coconut milk.

What can I use instead of cauliflower in a spinach banana smoothie?

Frozen zucchini, avocado, or extra banana are great substitutes for cauliflower in a spinach banana smoothie. And if you want to switch things up with fresh fruit, check out my guide on how to peel kiwi for easy prep and perfectly blendable pieces every time.

    I love this smoothie too. I put cauliflower rice in all of my smoothies. I feel like it adds extra nutrition, and I can’t taste it. I also like to add frozen blueberries.

  2. 5 stars
    Another great tasting smoothie, I was tempted to just use almond milk instead of coconut milk but I am glad I didn’t because the true essence came out with the coconut milk and I enjoyed every bit of it.

    I made this recipe x 5 as it is such a great jumping off point to a healthy and yummy breakfast. You can add cinnamon, vanilla, berries, peaches or mangos or cacao powder to make it a completely new flavor. The base of cauliflower and spinach cuts the effects of the sugar from the banana, as does the protein powder, which is really important for people who have had stomach surgery or have diabetes. Of course don’t take my word for it, talk to your doctor or just test it out. For me, it’s a perfect breakfast.

    This one so far is not a favorite for me . However I do love the use of my cauliflower in it .

  5. 4 stars
    This one is mostly good. I was out of milk but I happened to have a vanilla protein shake in the fridge so I used that in lieu of the coconut milk and protein powder. It was nice and creamy but could have used more banana. Also, counter to what many people claim, I do taste the cauliflower every time I try it in a smoothie. Since I like cauliflower this is not a big deal but is a distraction from the flavors I would prefer. Also, not sure which ingredient, I think the cauliflower, but this smoothie also left an aftertaste.

  6. 4 stars
    Had an odd bitterness to it but I am not sure if that is just reflective of my banana not being ripe enough. Will try it again for sure! Loved the consistency, nice and creamy.

    This one was my least favorite so far, but still good and still a winner. It’s not as sweet as the ones I’ve had this week and I can definitely taste the banana. I will have it again but maybe do less banana and/or add something else. Not sure what though.

    I think this one is my favorite so far! Soooo good!
    I never thought a smoothie would fill my tummy upas well as the 1st 4 have, and no hunger longer than anticipated as well.
    I be freezing daily green m smoothies – and using them for breakfast – on a regular basis now! Thank you Jen!

    I like the combination of the spinach and the orange I use spinach a lot in my smoothies.

  11. 5 stars
    Loved it! Very thick and creamy thanks to the cauliflower and frozen banana. I used cauliflower rice as it a lot easier to measure than florets. I will be enjoying this one a lot this winter.

  12. 5 stars
    A classic smoothie but still one of the best. I used 1/4 of a banana, increased cauliflower to 1/2 cup, 1/2 of an orange, used 1/2 cup of almond milk as that is what I had and added vanilla protein powder. Tastes great!

  13. 4 stars
    Not my favorite but it’s doable. It was creamy but didn’t care for the subtle taste of the cauliflower.

  14. 5 stars
    This is one of the family faves! I bought the protein powder you recommended and love that it doesn’t have a flavor. Great recipe!

    1. 4 stars
      It is not my favorite but still liked it.. I added 1 cup of cauliflowers just for the heck of it.. and used the exact measurements for the other ingredients but the taste of the banana was prevalent! I think I prefer to use water that coconut milk in my smoothies.

  15. 5 stars
    Jen is right, this smoothie is all about simplicity! I love that I can make it more filling or keep it simple!

  16. 5 stars
    I love green smoothies and enjoy these recipes with variety.
    I used coconut water instead of milk and a spring mix of spinach, kale and arugula for the greens.
    Excellent!
