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: 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 recommend coconut milk brands to help you shop. If you’re not a fan of coconut milk, swap with almond milk.
- 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 a powerful blender helps 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.
- 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 a few go-to frozen fruits and veggies 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: Freeze fresh 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 butters: 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.





















I enjoyed this but I’m not a huge fan of coconut milk in my smoothies. It did give it a creamy taste and went well with the citrus of the orange. I would definitely make it again but perhaps halve the coconut milk and make up with coconut water. But that’s just a personal taste thing.
Cauliflower is not my favorite. But in this smoothie, I didn’t mind it. It feels/tastes good knowing I’m starting the day nourishing myself.
I liked this smoothie, cauliflower certainly gives a creamy taste I also added a nob of fresh ginger love that zing taste, makes me feel that the smoothie is really doing my gut good
This smoothie is like coming home to comfort. It’s simply satisfying and nourishing, gentle on the belly, yet sweet on the palate. I really enjoyed this smoothie along with my morning coffee! Perfection!
Yum! So creamy
I really like this one. More like the smoothies I’m used to.
I liked today’s smoothie although I made changes. I used 3/4 cup coconut water since I don’t like coconut milk. I used 1/2 banana, 1/3 cup riced cauliflower, power greens instead of just spinach,1/2 serving whey protein ,a dash of cinnamon,and 1/4 teaspoon of vanilla extract. I love smoothies that have veggies in them.
I really enjoyed this smoothie. The flavors worked well together. It was creamy and filling. I added chia seeds and ground flax.
I was able to double to cauliflower and couldn’t taste it! I used the recommend homemade protein powder and seeds mix. My smoothie came out thick, creamy and just sweet enough. No complaints here! I’m definitely making it again with some of the intriguing optional additions to like oats or peanut butter.
This is a good, basic smoothie. While it wasn’t my favorite, it wasn’t bad at all. The vanilla protein powder made it creamy and almost dessert like without being too sweet. I would probably add some more orange next time, but that’s just me.
This was good not overly sweet.
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.
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 is a very tasty smoothie! I think it is a new favorite.
