Blanching is a process that involves briefly boiling vegetables before freezing them. This step is essential for preserving green beans’ color, texture, and flavor. It also helps remove any surface dirt and bacteria.
After blanching and cooling, it’s essential to dry the beans thoroughly. Excess moisture can lead to ice crystals and freezer burn. Spread the beans out on a clean towel and pat them dry.
Always label your packages with the date and contents. Store your green beans in a freezer at 0°F (-18°C) or lower. At this temperature, they can last up to a year without significantly losing quality.
