Freezer storage preserves banana bread for up to 4 months, allowing you to enjoy a slice that tastes almost as fresh as the day it was baked. Banana bread only stays fresh for a day at room temperature or 5 days in the refrigerator, making freezing a simple solution for small families who can't eat a whole loaf quickly.
Whole or Partial Loaves
Allow fresh-baked banana bread to cool completely before freezing so it doesn't create condensation that leads to soggy bread. Wrap the loaf tightly in plastic cling wrap to lock in freshness and hold the loaf shape -- wrap several times for the best protection. Slip the wrapped banana bread into a large freezer storage bag for an added layer of moisture-vapor protection. The banana bread stays fresh for 2 to 4 months in the freezer. Thaw frozen banana bread in its packaging at room temperature or in the refrigerator before serving.
Sliced Banana Bread
Consider freezing individual slices of banana bread if you don't think your family can eat the frozen portion within 5 days. To reduce crumbs when slicing, freeze the loaf partially and slice with a serrated knife. Wrap each slice tightly with several layers of plastic cling wrap. Group the individually wrapped slices together in a large freezer storage bag. Remove banana bread slices individually as needed, leaving the remaining slices in the freezer bag. This works well for packed lunches because you can remove a single serving in the morning, and it should thaw in the lunchbox by lunchtime.
