About the Turkey Cooking Time Calculator
For many families the turkey is the biggest thing they cook all year, and it is cooked only once or twice a year, so nobody remembers the timings. A turkey is also large and dense enough that the outside can look perfectly golden long before the centre is safe to eat. Timing the dinner around it — the potatoes, the stuffing, the guests — depends on knowing roughly how long the bird will take.
This turkey cooking time calculator gives the roasting time for a whole turkey by weight, stuffed or unstuffed, at the standard oven temperature of 325 °F (163 °C). It uses the widely published USDA roasting table, and adds the safe internal temperature, the resting time, how long the turkey takes to thaw, and how many people it will serve.

How the Roasting Time Is Worked Out
The time comes from a table of weight bands rather than a single rate per pound, because larger birds take less time per pound than small ones.
Weight band Unstuffed Stuffed
8–12 lb 2¾–3 h 3–3½ h
12–14 lb 3–3¾ h 3½–4 h
14–18 lb 3¾–4¼ h 4–4¼ h
18–20 lb 4¼–4½ h 4¼–4¾ h
20–24 lb 4½–5 h 4¾–5¼ h
24–30 lb 5–5¼ h 5¼–6¼ h
thaw in fridge ≈ 1 day per 4 lb
thaw in water ≈ 30 minutes per lbStep-by-Step Example
A 14 lb turkey, unstuffed.
Band: 12–14 lb, unstuffed = 3–3¾ hours at 325 °F
Thawing: 14 ÷ 4 = 3.5 → 4 days in the fridge
Cold water: 14 × 30 minutes = 7 hours
Serves: 14 ÷ 1.5 to 14 ÷ 1 = 9 to 14 peopleA 6 kg turkey, stuffed.
Weight: 6 × 2.2046 = 13.2 lb
Band: 12–14 lb, stuffed = 3½–4 hoursThe Temperature Is What Matters
The times are a guide for planning. The only reliable test of doneness is a food thermometer. A turkey is safely cooked when the thickest part of the thigh, the wing joint and the thickest part of the breast all reach 165 °F (74 °C). If the bird is stuffed, the centre of the stuffing must reach 165 °F too, because it absorbs raw juices while it cooks. Pop-up timers are not reliable enough on their own; check with a thermometer as well.
Start checking about 30 minutes before the shortest time in the range. Ovens vary, birds vary in shape, and a turkey that went into the oven slightly cold from the fridge will take longer.
Thawing a Frozen Turkey
Never thaw a turkey on the kitchen counter, where the outside warms into the danger zone for bacteria long before the inside thaws. There are two safe ways.
In the fridge, allow about one day for every 4 to 5 pounds. A 20 pound bird needs around five days, so it often has to come out of the freezer the weekend before a holiday.
In cold water, keep the turkey in its wrapping, submerge it in cold tap water and change the water every 30 minutes. Allow about 30 minutes per pound, and cook it as soon as it has thawed.
A turkey can also be cooked from frozen, but it takes about 50 percent longer, and the giblets can only be removed part way through.
Stuffed or Unstuffed?
Cooking the stuffing inside the bird gives it flavour, but it slows the cooking and makes it harder to get everything right at once: by the time the stuffing in the centre reaches 165 °F, the breast may be dry. Many cooks now bake the stuffing in a separate dish and fill the cavity with onion, lemon and herbs instead. If you do stuff the bird, stuff it loosely just before it goes into the oven, never the night before.
Getting a Moist Turkey
The breast cooks faster than the legs, so it is the part that dries out. Covering the breast with foil for the first part of cooking, or roasting the bird breast side down for the first hour, helps it and the legs finish together. Brining the turkey the day before, in salt water or with a dry salt rub, also keeps the meat juicier. Basting makes little difference to moistness and lets heat out every time the oven door opens.
Resting and Carving
Take the turkey out when it reaches temperature and rest it for 20 to 30 minutes, loosely covered with foil. The juices settle back into the meat, the bird becomes easier to carve, and it stays hot for well over half an hour — enough time to make the gravy and finish the vegetables in the oven.
Planning the Day
Work backwards from the time you want to eat. For a 14 pound unstuffed turkey served at 3 pm, allow 30 minutes of resting, about 3¾ hours of roasting at most, and an hour before that for the bird to lose its fridge chill and for the oven to heat, so it should come out of the fridge at about 9:45 am.
