For a stuffed 13 lb turkey, you’re looking at roughly 3.5 to 4.5 hours in a 325°F oven. Yes, that’s a range—because every oven lies a little, and your stuffing density matters. Always trust your thermometer over the clock. The thigh should hit 175°F, the breast 165°F, and—this is crucial—the center of the stuffing must reach 165°F too. If the stuffing is cold, hello, bacteria party.
Why the extra time? Because stuffing acts like a wet sponge, sucking heat away from the bird’s cavities. That’s why a stuffed turkey cooks slower than an unstuffed one. Don’t rush it. You’d rather have a turkey that’s done at 4.5 hours than one that’s raw in the middle at 3.
The “Tent and Rest” Survival Kit
Here’s where I almost ruined my second bird. After roasting, you need to let it rest for 30-45 minutes. Yes, you read that right. Take it out of the oven, tent it with foil, and walk away. The internal temperature will rise another 5-10 degrees (carryover cooking), and the juices will redistribute. Do not carve early, or you’ll get dry meat and soggy stuffing.
While it rests, you can make gravy, set out sides, or pour yourself a well-earned glass of wine. And if anyone asks why dinner is late, just say, “Science.” They’ll nod, confused but impressed.
