A lot of you wrote in asking for times for your specific turkey size. Use the USDA chart below as a guide–we all need to have some idea in order to plan the rest of the meal.

But keep in mind–this chart is a guide only, and you need to take the turkey's temperature with a thermometer to check for doneness.
