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!

Peanut Butter Banana Spinach Smoothie

Yield: 2 servings
Prep Time: 5 minutes
Cook Time: 0 minutes
Cuisine: American
Course: Breakfast, Drinks
This Peanut Butter Banana Spinach Smoothie is creamy, satisfying, and perfectly sweet. Made with just five, good-for-you ingredients, it is the perfect easy breakfast to start your day.


  • 2 handfuls spinach, fresh. See below for how to use frozen
  • 2 medium ripe bananas, fresh or frozen
  • 2 tablespoons peanut butter, or to taste
  • 1 ½ cups milk of choice, I used unsweetened almond
  • 2 scoops protein powder of choice, I like collagen powder. Or ½ cup Greek yogurt. Optional, but I find it helps to boost the protein of the smoothie
  • cup ice, omit if using frozen bananas



  • Combine all ingredients in a high-speed blender. Blend until smooth.
    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.
  • Check for consistency. If you prefer your smoothie thicker, add more ice and reblend. If you prefer your smoothie thinner, add more milk or water.
  • Enjoy immediately.


* If using frozen spinach, use about 1/2 cup
