High Protein Green Smoothie
Why this recipe works
- Fast to blend: Everything comes together in the blender in minutes, making it practical for a quick breakfast or snack.
- Naturally creamy: Ripe banana and avocado give the smoothie a thick, silky texture without needing ice cream or added thickeners.
- Balanced flavour: Spinach brings a fresh green note, while banana, peanut butter and optional honey soften the earthiness.

Texture tips
- Blend the greens first: Breaking down the spinach with the milk and yoghurt before adding the thicker ingredients helps prevent leafy flecks.
- Adjust the consistency: If the smoothie becomes too thick, blend in a little extra milk until it pours easily.
- Use ripe fruit: A ripe banana and avocado blend more smoothly and give the drink a fuller, creamier finish.
Ingredient notes
- Banana ripeness matters: A ripe banana adds sweetness and softness, reducing the need for extra honey.
- Choose your base: Whole milk gives a richer result, while oat drink makes the smoothie lighter and dairy-free when paired with a suitable yoghurt alternative.
- Use baby spinach: Baby spinach has a mild flavour and tender leaves, so it blends easily and keeps the smoothie fresh rather than bitter.
Make-ahead tips
- Best served straight away: The texture is smoothest and the colour brightest immediately after blending.
- Short-term storage: If needed, refrigerate in a sealed container for up to a day, then stir or re-blend before drinking.
- Prep the produce: Chill the banana and avocado in advance if you want a colder, thicker smoothie without adding ice.

Ingredients
Instructions
- Add the milk and yogurt to a blender, then add the spinach. Blend for 20 to 30 seconds until the spinach is fully broken down and the mixture looks bright green.
- Peel the banana and add it in. Halve the avocado, remove the stone, scoop out the flesh and add it to the blender along with the peanut butter.
- Add the chia seeds and honey, if using. Blend for 30 to 60 seconds until thick, smooth and silky; loosen with a splash more milk if you prefer it thinner.
- Pour into a glass and drink straight away while cold. If it thickens as it sits, give it a quick stir or re-blend for a few seconds.
