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.
I like the simplicity of this smoothie . I used frozen spinach that I previously froze to get that cold creamy texture. Works well and it taste good even after adding super greens powder.
Another good tasting smoothie! Perfect balance.
(Added 1/2 avacado …only had 1/2 banana left..hubby eats them alot lol..he also is drinking a smoothie which is a good way of sneeking in the greens!) I usually put cucumber/celery in mine,I think this would be good in this also. First for coconut water..nice flavor.
For me, this is the classic green smoothie. So easy to make, drink and “sell” to the kids. Ha. It tastes great and that color! It’s the perfect wow in a glass.
Day 4 Smoothie- Spinach and Orange is by far my favorite so far in the 10-day challenge! Love the zesty tartness of the lemon and citrus flavor of the orange. I am huge fan of Coconut water so I felt like this smoothie was made for me. Definitely going to keep this recipe around and make this smoothie on a weekly basis!
This is one of my favorite smoothies: it’s citrusy and sweet without being overbearing. I prefer to drink mine room temperature, so I use all fresh ingredients. What a great, refreshing drink to start the day with veggies and all my vitamin c!
I found the Spinach Orange Smoothie light and refreshing. I typically don’t care for coconut water but it’s good in this smoothie. Next time I’ll add an extra orange.
Loved this smoothie! The lemon was perfect.
I put the hole Orange and came out really thick still really good
Yummy. Love this. I didn’t have frozen citrus so it was more of a juice conistency, however that is fine as I’m having this as a mid-morning snack so is a bit ligther and refreshing. I know with frozen citrus it would have been thicker or I could have also added ice. A keeper for the summer.
OMG! The smoothie today is my absolute favorite. #Rawk On!!!
Just Delicious!
Great summer smoothie 😉
Perfect smoothie for a hot summer day. It’s so refreshing!
My first time putting lemon in a green smoothie.
I liked the fresh citrus flavor!!!
Not so much a fan of the lemon, but this was pretty good! 🙂
Of the Summer Challenge this one is my favorite so far. I peeled both my lemon and my orange and having read the blog post I wish I had put some of the zest in with the smoothie – next time. I will add that note to my recipe page. I thought the lemon would be overpowering, but it isn’t. This is light and refreshing with a light citrusy taste. Love it!
Day 4 of 10 day smoothie challenge; pretty tasty! Tasted like orange juice, lol! Might add some herbs to cut back on the citrus flavor next time.
Citrus tasting
This was a perfect smoothie for today! Crisp and fresh and perfect for the 100 degree weather were experiencing right now!
It was very tasty. The spinach gave it an a little off flavor so I added more banana and it was great. In fact, I could have gone for another one, but didn’t have enough time this morning. Will have it this evening, with less spinach which I love, and a bit more lemon for a bit of a night cap. I love these challenges they are really fun.
Perfect early summer morning breakfast! So delicious!
I agree! 🙂
