Tips for how to make the best green smoothie

Blend the spinach with the liquid first. This will ensure that the spinach (or whatever greens you are using) gets completely pureed. Finding a hunk of spinach stuck in your smoothie straw is a total bummer and this tip is especially helpful if you don’t have a high-speed blender like a Vitamix.

If adding everything at once, be sure to put the liquid in first and then the solid ingredients second. Even if you are using a high-speed blender. This will help the blender to puree your smoothie evenly.

Blend spinach banana smoothie on the highest speed your blender has so that it is smooth and creamy.

Suggested Adaptations

  • Replace the banana with mango. Or use 1 cup frozen mango and 1 banana.
  • Sub the spinach with kale.
  • Use frozen bananas and frozen spinach instead of ice.
  • Add a tablespoon of chia seeds, ground flax, or shelled hemp seeds for a boost of protein and healthy fats.
  • Use almond butter instead of peanut butter.
  • Add a tablespoon or two of cocoa powder to make this a chocolate smoothie!
  • For a nut-free option, replace the peanut butter with sunflower seed butter.
  • Replace the protein powder with 1/2 cup plain Greek yogurt.

Tip: if you don’t have a high-speed blender, blend the milk and kale first so that the greens get completely pureed. Then add remaining ingredients and blend again for a prefect green smoothie!

Ingredients
 

  • 2 handfuls spinach, fresh. See below for how to use frozen

  • 2 tablespoons peanut butter, or to taste
  • 1 ½ cups milk of choice, I used unsweetened almond

    If you don't have a high speed blender, blend ice, spinach, and milk first until spinach is pureed. Then add remaining ingredients and blend until smooth.

  • Enjoy immediately.
