About This Turkey Cooking Time Calculator
Our Turkey Cooking Time Calculator helps you achieve perfectly roasted turkey every time, whether you're preparing Thanksgiving dinner, Christmas feast, or a Sunday roast.
The calculator uses time-per-pound cooking rates based on USDA Food Safety guidelines and Safefood Ireland research. The core algorithm accounts for five critical variables: turkey weight (lbs or kg), preparation type (unstuffed, stuffed, crown, boneless, or spatchcock), oven type (conventional, convection/fan-assisted, or gas), cooking temperature (325°F, 350°F, 375°F, or two-stage professional method), and desired doneness level (safe minimum 165°F, recommended 170°F, or well-done 180°F).
The base formula is: Cooking Time (minutes) = Weight (lbs) × Rate (min/lb) × Doneness Multiplier. Standard rates range from 8-16 minutes per pound depending on your selections. For the two-stage professional method, the calculator applies 0.25 min/lb at 425°F for initial browning, then standard 350°F rates for the remainder.
Doneness multipliers adjust the time: 1.0× for safe minimum (165°F/74°C internal), 1.05× for recommended medium (170°F/77°C), and 1.12× for well-done dark meat (180°F/82°C). The calculator also adds a mandatory 30-minute resting period, which is essential for juicy, flavorful results.
Beyond basic time calculation, this tool provides a detailed cooking schedule with actionable milestones, a visual temperature comparison chart, food safety checklist based on USDA and Safefood guidelines, estimated turkey costs by size, and expert tips tailored to your specific cooking scenario.

Frequently Asked Questions
Do you cook turkey at 325°F or 350°F?
Both temperatures work, but serve different purposes. At 325°F, a 12 lb unstuffed turkey takes about 2 hours 36 minutes, cooking more gently and evenly—ideal for birds over 18 lbs. At 350°F, the same turkey takes about 2 hours 12 minutes, which is faster and works well for most home cooking. The USDA recommends 325°F as the minimum safe temperature.
How many hours do I cook a turkey per pound?
Cooking time varies by preparation. For an unstuffed whole turkey at 325°F, expect 13 minutes per pound. A stuffed turkey at the same temperature needs 15 minutes per pound. Turkey crowns cook faster at 10 minutes per pound, while spatchcock (butterflied) turkeys need only 8 minutes per pound at 325°F.
How long to cook a turkey at 325°F calculator?
Using our calculator: a 12 lb unstuffed turkey at 325°F takes approximately 2 hours 36 minutes. A 16 lb turkey takes about 3 hours 28 minutes. For a 20 lb turkey, plan for 4 hours 20 minutes. Add 30 minutes resting time after removing from the oven for optimal juiciness.
Is it 30 minutes per pound for turkey?
No, 30 minutes per pound is excessive for most cooking methods. At 325°F, unstuffed turkeys require 13 min/lb, stuffed turkeys need 15 min/lb. Even at lower temperatures or with stuffing, times rarely exceed 16 min/lb. The 30 min/lb figure may apply to very slow cooking at 275°F or below, which is not USDA-recommended.
Can you start a turkey at 425°F then 350°F?
Yes, this two-stage method is favored by many professional chefs. Start at 425°F for 25-30 minutes to brown the skin, then reduce to 350°F for the remainder. For a 12 lb turkey: 25 min at 425°F + about 2 hours at 350°F = roughly 2 hours 25 minutes total. Our calculator supports this method automatically.
How do I keep my turkey from drying out?
Key strategies: (1) Use a meat thermometer and remove at 165°F—overcooking is the #1 cause of dryness. (2) Rest for 30 minutes after cooking to let juices redistribute. (3) Baste every 45 minutes with pan juices. (4) Consider brining the turkey 12-24 hours before cooking. (5) Cover the breast with foil for the first two-thirds of cooking, then remove for browning.
