High Protein Green Smoothie

Green smoothies work best when they feel creamy rather than grassy, and this version leans on banana and ripe avocado for a thick, silky texture. Baby spinach gives the drink its bright colour and gentle earthy note, while Greek yoghurt and milk make it more substantial for breakfast or a post-workout snack. Peanut butter adds a rounded nuttiness that sits well with the fruit, with chia seeds and honey available for extra texture or sweetness. Blending the greens first keeps the finish smooth, and the smoothie is best served cold straight after blending.

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.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
