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.

  1. Add your base ingredients. Add spinach, peeled orange, banana, frozen cauliflower, and chilled coconut milk to your blender.
  2. Blend until creamy. Start on low, then increase to high until completely smooth. Stop and scrape the sides if needed.
  3. Optional protein boost. Add protein powder and blend briefly, just until combined.
  4. 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.

Common Questions

Will the spinach banana smoothie taste like spinach?

Nope. Spinach has a very mild flavor, and in this spinach banana smoothie it’s completely balanced by sweet banana and bright orange.

Do I need a high-speed blender to make this smoothie?

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.

Can I use a different milk in this spinach banana smoothie?

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.

What can I use instead of cauliflower in a spinach banana smoothie?

Frozen zucchini, avocado, or extra banana are great substitutes for cauliflower in a spinach banana smoothie.

    Your classic citrus smoothie. I added thyme and chia seeds to add a little oomph.

    1. So glad you’re gettin that immune boosting Vitamin C kick Dawn! 🙂

  2. I only use powders to mix my smoothie with coconut water. The blend of powders I use is spinach, kale, orange peel powder. The fruits and veggies are all organic. I blend them in a blender in my kitchen. Is it okay to mix powders for a smoothie? I all so thought of adding hemp hearts, flaxseed. Is it all right to blend all of this together?

    1. Great question! We prefer the nutrients obtained from using fresh greens like kale and spinach, yet if the powdered version is what’s available to you then it’s def better than not at all! Adding hemp and flaxseed are great ways to up that protein content in your smoothie. In fact, those are two of the ingredients in our homemade protein powder!

    I gave this smoothie just one star. It’s been my least favorite so far….but still fun to try new combos. It was just too sharp for me. I like some tanginess but this was a little too much for me.

    I really enjoyed this smoothie, I used Meyer lemons so they were on the sweeter side. Perfectly tart and sweet at the same time.
