To freeze green beans, first blanch them in boiling water, and then allow them to cool in ice water, drain them, and pack them into containers. Shake the containers to settle the beans inside, and label the containers with the date and contents then place in the freezer.
The process for blanching and freezing green beans requires bringing a large pot of water to a rapid boil. Chop the stems off the beans, and cut them into bite-sized pieces. When the water reaches a rapid boil, drop the green beans into the water in batches. Allow the beans to boil two minutes for bite-sized pieces or four minutes for long pieces.
Cool the beans by dropping them into a bowl of ice water. Once cooled, allow the beans to drain before packing them in freezer-safe containers.
