Quick breads are best if they are tightly wrapped and stored in the refrigerator overnight. After the bread has completely cooled, wrap it tightly in plastic or foil. As the bread chills, both the flavor and the moisture permeate the bread. The bread can be stored in the refrigerator for five to seven days.
Quick breads can also be frozen. Place the wrapped breads in freezer-grade plastic bags and freeze them for up to three months. When ready to use, thaw the loaves in the refrigerator while still wrapped.
