It all comes down to time and temperature. You want to cook your stuffed turkey at a temperature of around 325°F (165°C), and for a time that's determined by the turkey's weight. For example, a 12-14 pound (5.4-6.3 kg) turkey will take around 3-3 1/2 hours to cook.
But, here's the thing: you can't just set it and forget it. You need to check the temperature regularly to make sure it's reaching that all-important 165°F (74°C) internal temperature. And, let's not forget about the stuffing - it needs to be cooked to a 165°F (74°C) as well.
Now, you might be wondering, why is it so important to cook the stuffing to the right temperature? Well, it's because bacteria like Salmonella can thrive in undercooked stuffing. And, trust me, you don't want to be serving up a side of food poisoning with your holiday meal.
