  • 1 medium ripe banana (previously peeled and frozen // ~1 cup as original recipe is written)
  • 1/2 cup sliced cucumber (organic when possible // skin on)
  • 3/4 - 1 cup light coconut milk (or other non-dairy milk // less for thicker smoothie, more for thinner smoothie)
  • 1 cup spinach or chopped kale (organic when possible // I like to freeze mine)
  • 1 tsp spirulina powder*
  • 1 Tbsp hemp seed (optional // or sub chia seeds or vegan protein powder)

FOR SERVING optional

  • 1/4 cup frozen or fresh blueberries (organic when possible)
  • 1/4 cup granola (store-bought or homemade*)


  1. To a blender*, add frozen banana, cucumber, coconut milk, spinach, spirulina, and hemp seed (optional). Blend until creamy and smooth, scraping down sides (or using smoothie wand) as needed.
  2. If too thick, thin with water or more coconut milk. If too thin, thicken with ice or more frozen banana. Taste and adjust flavor as needed, adding more banana for sweetness, cucumber for freshness, or greens or spirulina for green color. See note about spirulina (brands + how much to add).
  3. Serve immediately as is or in my preferred: top with blueberries, granola, and more hemp seeds. Best when fresh, though leftovers will keep covered in the refrigerator up to 2 days or the freezer for 1 week. Thaw to enjoy from freezer.


*I use the Now Organic Spirulina powder, which was $13 at Whole Foods, but it can also be found online. I've also heard good things about this brand and this brand.
*When adding spirulina to smoothies, start with 1 tsp and add more as desired, but this is the max for me without tasting it. Otherwise, it can start tasting a little seaweedy.
*Granola recipes: Peanut Butter Chocolate Chip Granola, Banana Bread Granola, Simple Quinoa Granola, or Nut 'n' Honey Granola (the one I used in photos).
*Find my blender review here: Vitamix vs Blendtec.
*Spirulina also works extremely well when added in the same quantity to my Ginger Colada Green Smoothie!
*Nutrition information is a rough estimate calculated without toppings or hemp seeds.
