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 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.
- 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 the bright flavours in this smoothie. Made for a great breakfast with the addition of Greek yogurt, matcha, hemp hearts, chia seeds, and flax seeds!
I wanted something sweet so my spinach orange blend was a good alternative. I added avocado which made the smoothie creamier…yummy! It was my first time using coconut water and I will definitely be using it in other smoothie recipes. Day 4 blend was good!
The spinach orange smoothie was refreshing. I added some chia seeds to it. This smoothie was good but not my fav.
I was surprised how much I liked this smoothie. I didn’t have coconut water, so I used regular water. I also used a frozen banana and kale. It was delicious, so fresh!
Very refreshing
This one is refreshing and delicious especially on a nice sunny day. Will be making this again!
What a refreshing smoothie.! Definitely will make it again.
Loved this one! A lot thinner, which I liked!
Refreshing and delicious. Will be a repeat smoothie for me!
Day 4 of the Challenge offered this wonderfully refreshing Smoothie! I like the sweetness!
I love lemons! So far this my fav.
Refreshingly good fruits and you got in your greens as well. I really liked this one. The lemon is a great add.
Day 4 of challenge…another yummy smoothie!
It was good. Not cold enough for me so I threw on some ice.
Delish!
I love how the 1/2 lemon adds distinction to this recipe. At first I thought it might be too much, but it was perfect. So far all the SG Smoothies I have tried are full of complex and deep flavors. Another winner!
Love this one! light, refreshing, hydrating
Love the citrus taste!
This is a winner! Loved the freshness that the citrus added to the smoothie. I had all my ingredients chilled overnight and this helped brighten the flavors. Definitely will be making again.
One of my fave smoothies! Tangy and creamy! Yum! I added in some ginger and turmeric for an immuno boost.
