Keeping bread in the refrigerator can help prolong its freshness compared to leaving it at room temperature. However, refrigeration is not the best method for storing bread for extended periods, as it can dry out the bread and cause it to go stale faster. Additionally, refrigeration can promote the growth of mold on bread over time.
If you plan to keep leftover bread in the refrigerator, it's best to consume it within 2 to 5 days. The exact time frame can vary depending on the type of bread, its moisture content, and how well it's wrapped or stored.
To extend the shelf life of bread and prevent mold growth, you can consider freezing it. Slice the bread into portions, wrap them tightly in plastic wrap or aluminum foil, and place them in a resealable freezer bag. Frozen bread can last for several months and can be thawed or toasted as needed.
