You can do as little or as much at a time as you like. I like to do enough to fill a gallon size freezer bag, or just freeze as many greens as I happen to have—even if it’s just a small amount lingering in the fridge. Doing this also helpfully knocks down the “green” flavor!


  • 1 bunch kale or bag of spinach


  1. Wash, dry, and remove kale leaves from the stems. Place into a zip top freezer bag.
  2. Seal the bag, removing as much air as possible. Freeze!
  3. Remove frozen kale from the freezer.
  4. Crush the leaves to make them easy to measure for smoothies and to help the bag take up less space in the freezer.
  5. Measure out 1/2 cup for your green smoothie.


Crush the frozen greens for a more compact bag in the freezer and for easier measuring.

Blend the smoothie very well to incorporate all of the greens.

You can experiment with adding more to a smoothie, but taste it before you give it to the kids to make sure it’s sweet enough.
