To freeze fresh green beans, start by washing them and snipping off both ends. Optionally, cut them into smaller pieces for easier storage. Next, blanch the green beans by boiling them for about 3 minutes, then immediately placing them in an ice water bath for 3-5 minutes to stop the cooking. After blanching, drain and dry the beans thoroughly, then spread them out in a single layer on a baking sheet to freeze individually for 4-6 hours. Once frozen, transfer the beans to an airtight freezer-safe container or bag, removing as much air as possible, and store them in the freezer for up to 12 months. Freezing after blanching preserves the beans’ vibrant color, crisp texture, and nutritional quality better than freezing without blanching.
