To keep your zucchini bread fresh, store it at room temperature for 2 to 3 days, covering it well to prevent dryness. For longer-term storage, you can freeze it for 2 to 3 months. It's best to slice the bread and individually wrap each slice for easier thawing. When you're ready to enjoy it, let it come to room temperature. Alternatively, you can quickly reheat the bread using a toaster or microwave.
