A turkey cooking time calculator takes the guesswork out of roasting by computing precise cooking times based on your turkey's weight, stuffing status, and oven temperature. It also shows required resting time and the safe internal temperature target.
Turkey Details
Always verify with a meat thermometer in the thickest part of the thigh.
Roasting Time Reference (325°F / 163°C)
| Weight | Unstuffed | Stuffed |
|---|---|---|
| 8–12 lbs (3.6–5.4 kg) | 2¾–3h | 3–3½h |
| 12–14 lbs (5.4–6.4 kg) | 3–3¾h | 3½–4h |
| 14–18 lbs (6.4–8.2 kg) | 3¾–4¼h | 4–4¼h |
| 18–20 lbs (8.2–9.1 kg) | 4¼–4½h | 4¼–4¾h |
| 20–24 lbs (9.1–10.9 kg) | 4½–5h | 4¾–5¼h |
How to Calculate Turkey Cooking Time
Turkey cooking time depends on three variables: weight, whether it's stuffed, and oven temperature. A stuffed turkey always takes longer because the stuffing in the cavity must also reach 165°F.
Rule of Thumb for Roasting at 325°F
Unstuffed: allow 15 minutes per pound. Stuffed: allow 18-20 minutes per pound. These are estimates — your specific turkey's shape, depth of chill, and oven calibration all affect actual cook time.
Always Use a Meat Thermometer
Insert a meat thermometer into the thickest part of the thigh, not touching the bone. The target temperature is 165°F (74°C). Check the breast as well. For stuffed turkeys, check the stuffing temperature too.
Resting Time Is Not Optional
Tent the turkey with foil and rest for 20-45 minutes before carving. During this time, the temperature continues to rise slightly (carryover cooking) and juices redistribute throughout the meat.
FAQ
How long do I cook a turkey per pound?
At 325°F: unstuffed turkeys cook about 15 minutes per pound; stuffed turkeys about 18-20 minutes per pound. A 15-lb unstuffed turkey takes about 3.5-4 hours. Always verify with a meat thermometer — never rely solely on time.
What internal temperature is a cooked turkey?
The USDA recommends 165°F (74°C) in the thickest part of the thigh, not touching the bone. Check the breast too — it should also reach 165°F. If stuffed, the stuffing must also reach 165°F.
Should I roast a turkey covered or uncovered?
Roast uncovered for crispy skin. If the breast starts browning too quickly, tent loosely with foil. Remove the foil for the last 30-45 minutes to re-crisp the skin.
How long should turkey rest before carving?
Rest at least 20-30 minutes for a small turkey (10-12 lbs), 30-45 minutes for a large one (18+ lbs). Resting allows juices to redistribute. Tent loosely with foil to keep it warm.
