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.

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: One my favorite natural sweeteners that balances the citrus and adds creamy thickness to 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, and powerful smoothie blenders help create a smooth, creamy texture without pulp or grit.
- 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.
- Blend until creamy. Start on low, then increase to high until completely smooth. Stop and scrape the sides if needed.
- Optional protein boost. Add protein powder and blend briefly, just until combined.
- 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.

Nope. Spinach has a very mild flavor, and in this spinach banana smoothie it’s completely balanced by sweet banana and bright orange.
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.
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.
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.
Loved it. Lots of citrus notes in this one!
Bright and refreshing
Great flavors. I taste more of the orange but I think the lemon and banana enhance the flavor. I tried this smoothie with and without the protein scoop just to see the difference. There’s really no difference. Great taste.
I added half an avocado and 2 tbsps of chia seeds, which likely attributed to the thick consistency. I had to add water to thin it out. I enjoyed the taste. The orange flavour was very mild; perhaps my orange didn’t have much flavour?
Great question Grace! Actually, adding the avocado and additional chia would def knock down the sweetness and orange flavor in this smoothie. Try it without next time to see if you notice the difference.
The citrus flavor is so refreshing. I will be making this one again.
Loved the colour, very appetizing. Pretty good. Enjoyed it but #1 is still my favourite. Probably due to the sweetness. I must say though that having a smoothie for breakfast every morning, when I usually skip this meal has seem to curbed my appetite during the day to snack on things that are not very good. I am eating more regularly with smoothie in the morning, lunch and dinner. No more and I don’t miss the chips, chocolate and all that other stuff during covid I’ve been over eating.
I really liked this smoothie. I was a vibrant green and the flavors of the fresh orange and lemon really made it pop.
Taste was good but left too many piece that didn’t blend.
Surprisingly refreshing and not too tart!
YUM!!! We loved this one. I love that the coconut water was sweet which is always good as a base. We also used a big orange and used the bigger half of a banana. Perfectly sweet, hydrating and oh so good!!
Loved it
This smoothie was very refreshing.
OMG!!! Absolutely DELICIOUS!!!! I don’t typically like sour flavors, so when I saw that this required a Lemon, I was like ok, I know I’m going to have to add some DATES (which I did). Not only do I not really care for Lemons, but the grocer gave me Limes instead. So, I went with what I had and to my PLEASANT surprise, this was absolutely DELICIOUS!!!! And of all the smoothies that didn’t yield more than it said it would, it would be this one…lol! This one is definitely a keeper!
I enjoyed the citrus punch from this smoothie!
This is very similar to the citrus smoothie. I swapped the coconut water for coconut cream to boost the flavor and fullness factor. I think this would be a good winter smoothie, since oranges aren’t in season currently.
This one has a bit of tang from the lemon. It is delicious! I added some protein powder to have it as a meal replacement. The texture of this one is very good–not too thin or too thick. Yum!
I liked this a lot. Very refreshing with the coconut water. I used some frozen mango instead of banana, and added an unflavored mushroom protein powder. So good.
I absolutely love this smoothie. It even holds up to adding a little protein powder and a few chia seeds. My husband even loved it, and he’s not a huge smoothie fan. Yet!
Loved this vibrant green colored smoothie. It was delicious.
Good flavor. Feeling healthier with all my greens and fruits so far this week.
