- prep
Gather and prep the ingredients.
Peel the banana and break it in half. Measure out the spinach, frozen mango, yogurt, whey protein, and cold water. Have everything ready next to the blender.

Blend until completely smooth.
Start on low speed and gradually increase to high. Blend for 45 to 60 seconds, or until the mixture is fully smooth with no visible spinach flecks. If it's too thick, add an extra tablespoon of water and blend again.
TIPDon't over-blend once smooth — the friction can heat the smoothie and thin it out. - assemble
Check consistency and adjust.
Stop the blender and check the thickness. If you prefer a thinner smoothie, add 2-3 tablespoons of cold water and pulse a few times. For a thicker smoothie, add 1-2 ice cubes and blend again.
- serve
Pour into a glass, top with chia seeds, and serve immediately.
Pour the smoothie into a tall glass. Sprinkle chia seeds on top if desired. Enjoy right away while cold and creamy.
TIPFor the best texture, drink it within 10 minutes. Separation is natural — just stir if it sits.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Freeze your banana in chunks for a creamier texture without needing ice.
- 2Layer liquids first to help the blender draw ingredients down into the blades.
- 3Use unflavored whey to let the fruit sweetness shine without artificial aftertaste.
- 4Blend in short bursts on low before ramping up to prevent powder from flying up.
- 5If your smoothie is too thick, add cold water one tablespoon at a time to keep it chilled.
- 6Rinse the blender immediately after pouring to prevent protein residue from sticking.

Dairy-free
Swap Greek yogurt for unsweetened coconut or almond milk yogurt and use a plant-based protein powder — perfect for lactose-intolerant or vegan diets while keeping the creamy texture.
green boostGreen boost
Add a handful of fresh mint or a 1/4 of an avocado for extra chlorophyll and healthy fats — the avocado makes it even silkier without changing the taste.
low sugarLow-sugar
Replace half the mango with frozen zucchini chunks or cucumber — cuts natural sugars while maintaining the green color and creamy volume.
Why this is on our healthy list.
High-Quality Muscle Fuel
Unflavored whey protein delivers all essential amino acids for post-workout recovery, and the banana provides quick-digesting carbs to replenish energy stores.
Rich in Iron and Vitamin K
Baby spinach is packed with iron (for oxygen transport) and vitamin K (for bone health), and the vitamin C in mango helps your body absorb that iron more efficiently.
Digestive Support
Greek yogurt adds probiotics for gut health, and the fiber from spinach, mango, and banana promotes regularity and lasting fullness.
Frequently asked questions
Yes, but reduce the water to 1/4 cup and add a handful of ice — frozen spinach releases a lot of liquid and can make the smoothie watery if not adjusted.
