When boneless, skinlees chicken breasts are on sale, stock up. Wrap the breasts individually in plastic wrap, then pop them in a resealable plastic bag. Later, remove exactly the amount you need.
For optimum food safety, thaw frozen chicken gradually in the refrigerator, never at room temperature. Place the frozen wrapped chicken on a tray in the refrigerator and allow about 12 hours to defrost 2 to 3 pounds of chicken.
Many of us, however, prefer last-minute microwave thawing. Each microwave manufacturer has specific instructions for defrosting foods; some microwaves have "smart" defrost features that calculate time automatically when you punch in the food's weight and type. Microwave thawing may defrost unevenly, so cook foods right away to eliminate the possibility of bacterial growth.
