At 325°F, a 13.5 lb turkey needs about 3 to 3.5 hours. Yes, that’s it.
But here’s the trick: trust your thermometer, not the clock. Turkeys are sneaky.
They’ll look golden on the outside and still be raw near the bone if you’re not careful. Don’t be that person.
How to Calculate Like a Pro
The old rule is 15 minutes per pound at 325°F. Do the math: 13.5 x 15 = 202.5 minutes.
That’s 3 hours and 22 minutes. Call it 3 hours and 20 to 30 minutes.
But wait—don’t toss that calculator yet. If your turkey is stuffed, add 30 to 45 minutes. Stuffed birds are divas; they take their sweet time.
