Turkey Cooking Time Calculator
Calculate turkey cooking time by weight, stuffing, and method.
Covers traditional roasting, high heat, spatchcock, and slow roast with USDA safe temperatures.
USDA Turkey Cooking Guidelines The United States Department of Agriculture (USDA) provides evidence-based guidelines for cooking turkey safely. The key principle: it is internal temperature that determines doneness, not color or juices alone.
Safe Internal Temperatures
- Turkey breast: 165°F (74°C). This is the safety number, for every part of the bird.
- Turkey thigh: 175°F (79°C), which is a texture target rather than a safety one. Dark meat is full of connective tissue that only softens above 165, so a thigh pulled at the safe minimum is perfectly safe and slightly rubbery.
- Stuffing (inside bird): must also reach 165°F (74°C)
Cooking Time by Method
Traditional Roasting at 325°F (163°C):
Minutes per pound is the wrong way to think about a turkey, and it is why so many charts disagree. A big bird has less surface for its volume than a small one, so it cooks more slowly per pound but not proportionally slower overall. The rate falls from roughly 20 min/lb at 8 lbs to about 12.5 min/lb at 24. This calculator interpolates the USDA table below rather than applying one rate to everything.
| Turkey Weight | Unstuffed | Stuffed |
|---|---|---|
| 8 to 12 lb | 2¾ to 3 h | 3 to 3½ h |
| 12 to 14 lb | 3 to 3¾ h | 3½ to 4 h |
| 14 to 18 lb | 3¾ to 4¼ h | 4 to 4¼ h |
| 18 to 20 lb | 4¼ to 4½ h | 4¼ to 4¾ h |
| 20 to 24 lb | 4½ to 5 h | 4¾ to 5¼ h |
Higher Heat at 350°F (177°C):
- Reduces time by roughly 10% compared to 325°F
- Browns the skin better, at some risk to the breast drying out
Spatchcocked (Butterflied) at 450°F (232°C):
- The backbone comes out and the bird is pressed flat, which greatly increases surface area
- Cooks in about 7 to 8 minutes per pound
- Crisper skin all over, and faster, more even cooking
Slow Roast at 250°F (121°C):
- Very gentle, low heat
- Unstuffed: 20 to 25 minutes per pound
- Produces extremely moist meat but skin rarely crisps
Resting Time Rest for 30 minutes on a bird under 16 lbs and 45 minutes on anything larger. Carving early is the most common cause of a dry turkey: the juices have not had time to settle back into the muscle and end up on the board instead. A whole turkey holds heat remarkably well, so 45 minutes tented with foil will not leave you serving it cold, and it frees the oven for everything else.
Basting Basting adds flavor but does not speed cooking up in any meaningful way. Every time the oven door opens the temperature drops 25 to 50°F, which can add fifteen minutes per look. A leave-in thermometer with a cable through the door seal solves this properly: you get the number without ever opening the oven.
