Ingredients Equipment Method Notes

Ingredients
  

  • Half a large or 1 small very ripe banana
  • 1 cup milk (or dairy substitute)
  • 2 cups fresh baby spinach
  • 1 tablespoon unflavored collagen peptides (my unique twist!)
  • 1/2 fresh lime juiced
  • A few ice cubes (optional, depending on your banana)

Equipment

  • Blender

Method
 

Prep Your Ingredients
  1. Before blending, ensure all your ingredients are ready. Give your fresh baby spinach a quick wash. If using a fresh banana, peel and slice it into a few pieces. Have your milk, collagen, and lime juice measured and nearby.
Load the Blender Smartly
  1. The order you add ingredients to your blender matters for optimal blending. Start with your liquids first—that’s your milk (or dairy substitute) and the fresh lime juice. Next, add the softer ingredients, like your fresh baby spinach. Finally, pile in your harder or frozen components: the banana (fresh or frozen), the unflavored collagen peptides, and any ice cubes you're using. This layering helps create a vortex for super efficient blending.
Blend to Perfection
  1. Begin blending on a low speed to incorporate the ingredients, then gradually increase to high speed. The goal here is a perfectly smooth, creamy, and vibrant green consistency. Blend until absolutely no spinach flecks remain—you want it silky and luscious. This might take 1 to 2 minutes, especially if you're using frozen banana or a less powerful blender. Don't be afraid to pause and scrape down the sides of the blender jar with a spatula if needed. You’ll know it’s done when it pours out in a smooth, thick stream, feeling wonderfully frosty and refreshing.

Notes

Smoothies are best enjoyed right after you make them for peak freshness, texture, and color. For make-ahead, the best strategy is to freeze pre-portioned dry ingredients (sliced frozen banana, spinach, collagen) in bags, ready to blend with liquid and lime juice whenever you want a fresh smoothie. Always use very ripe or frozen bananas for optimal sweetness and creaminess. Layer your blender smartly: liquids first, then soft ingredients, then frozen items and ice, and blend until silky smooth.
