how long do you cook a thirty pound fresh turkey stuffed

Hi! Wow, that's a big turkey! Stuffed birds take longer to roast than unstuffed—so, for a stuffed bird that size, figure about 5 1/2 to 6 1/2 hours in the oven. That said, a meat thermometer really is the best way to know when they turkey is ready. Target temperatures are 165°F for the breast and 175°F for the thigh. Hope this helps and happy Thanksgiving!
