How long should I allow for my frozen turkey to thaw in the fridge?
It can take quite a while for a large turkey to thaw in the refrigerator: figure on at least 5 hours per pound, so a 12- to 14-lb. bird can take two-and-a-half to three full days to thaw.
Do NOT try to speed up the thawing process by leaving the turkey at room temperature overnight (or even for a few hours). You can safely speed it up, though, by putting the turkey (still in its wrapper) in your kitchen sink and covering it with cold tap water. Every half hour, drain the water and refill the sink. Using this method, the turkey will thaw at a rate of about 30 minutes per pound.
