Blanching green beans is the time-honored way of freezing green beans.
Wash green beans. Remove ends. String the beans if necessary. Cut into pieces if desired.
Bring a pot of water to a boil. When boiling, add green beans. Blanch for 3 minutes.
While beans are cooking, prepare a bowl of ice water.
After beans have cooked, drain. Add beans to ice water. Allow to cool completely. Drain again. Remove any remaining ice.
Shake colander gently to remove all excess water. For best results, pat beans dry with a lint-free towel.
Pack green beans into labeled freezer bags or containers. Freeze.
