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 a bright and creamy spinach smoothie, but now it keeps you full, fueled, and satisfied for hours.
This one made my list of high-calorie smoothies for weight gain for sneaking in extra nutrients without tasting “green” — if you love this tropical flavor, try my Weight Gain Smoothie, or keep it simple with my Creamy Banana Smoothie or any of my other easy banana smoothies.

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.

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.

Common Questions
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.

Recipe Notes
- Milk Swaps: If you’re not a fan of coconut milk, use almond milk, oat milk or another non-dairy milk.
- Vegan Swap: Use a plant-based protein powder in place of the whey.

This smoothie was even better than day 2
So glad you enjoyed this smoothie!
I like the combination of the spinach and the orange I use spinach a lot in my smoothies.
Two of my favorite ingredients. So glad you enjoyed this one!
Creamy yummy smooth!!!
Creamy for the win!
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.
So excited you liked this one! Cauliflower rice does make it super easy.
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!
So glad you made the smoothie your own!
