What This Calculator Does
The Turkey Cooking Time Calculator estimates how long to roast a turkey in a conventional oven at 325°F (163°C). Cooking time scales roughly with the bird's weight, so this tool multiplies your turkey's weight in pounds by a standard minutes-per-pound rate and converts the result into hours and minutes.
How To Use It
Enter your turkey's weight in pounds (use the thawed, ready-to-cook weight). Choose whether the bird is stuffed or unstuffed — stuffing slows heat penetration, so it adds time. The calculator returns a total roasting estimate. Always confirm doneness with a meat thermometer: the thickest part of the breast should reach 165°F (74°C) and the inner thigh 175°F (79°C).
The Formula Explained
The core equation is $$\text{cook\_minutes} = \text{weight\_lb} \times \text{minutes\_per\_lb}$$ At 325°F, a common guideline is about 13 minutes per pound for an unstuffed turkey and roughly 15 minutes per pound for a stuffed one. Total minutes are then split into whole hours and leftover minutes for easy planning.
Worked Example
For a 12 lb unstuffed turkey: $$12 \times 13 = 156 \text{ minutes} = 2 \text{ hours } 36 \text{ minutes}$$ For a 16 lb stuffed turkey: $$16 \times 15 = 240 \text{ minutes} = 4 \text{ hours}$$
FAQ
Should I cook covered or uncovered? Roast uncovered, tenting the breast with foil if it browns too fast. These estimates assume a standard open roasting pan.
How much time should I add for resting? Let the turkey rest 20–30 minutes after roasting before carving so juices redistribute — plan that on top of the cook time shown.
Are these times exact? No. Oven calibration, starting temperature, and pan type all affect timing. Use a thermometer to confirm 165°F before serving.
