Use a food thermometer: USDA says check 165°F in the thickest breast and innermost wing and thigh; if stuffed, the center of the stuffing must also reach 165°F. The estimate uses a 325°F oven assumption. Source: USDA FSIS, https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/poultry/turkey-basics-safe-cooking."
