Turkey timing depends on size, oven method and temperature; a food thermometer helps determine doneness.
What changes cooking time
A turkey’s cooking time changes with its weight, shape, the accuracy of the oven and whether it is whole or flattened. Use a chart for planning, not for deciding that it is definitely safe.
Safe internal temperatures
Insert a clean food thermometer in the thickest sections without touching bone. The safe minimum internal temperature for poultry is 165°F (74°C).
Resting a cooked turkey
Once safely cooked, rest the turkey before carving to make slicing easier and help retain juices. Refrigerate leftovers promptly.
