Turkey Cooking Time Calculator: How Long to Cook a Turkey (by Weight)

My first Thanksgiving turkey was still partly frozen at 10 o'clock on Thanksgiving morning. I had bought a 16 pound bird on Monday, put it in the fridge like the label said, and assumed three days was plenty. It was not. I spent the morning in a panic, with the turkey in a sink full of cold water and my husband quietly calling the pizza place just in case. We ate at 8 at night, and the breast was dry. I promised myself it would never happen again.

Back home in Karachi, my mother never roasted a whole turkey. Our big family dinners meant biryani, karahi and stacks of hot chapati, and nothing that needed a thermometer. So when I started hosting Thanksgiving for friends here in the US, I had to learn the turkey cooking time rules from scratch. I made charts, tested birds of different sizes, and wrote notes in the margins of every recipe I tried.

Those notes became this free turkey cooking time calculator. You type in the weight of your turkey and the time you want to sit down to eat, and it tells you the oven temperature, how long to roast it, when to take it out, and how long to rest it. Then it builds a full schedule for the day, working backward from dinner time, and you can add every step to your phone calendar with one tap.

Saad and Zainab now count down to Thanksgiving the way I used to count down to Eid, and my husband no longer keeps the pizza number handy. Below the calculator I share everything I have learned since that first frozen bird: how big a turkey to buy, how to thaw it in time, how to tell when it is done, and the timeline I follow every year. It works for prime rib, ham, chicken and lamb too, so keep it bookmarked for Christmas and Easter.

TURKEY COOKING TIME CALCULATOR

Choose Turkey, enter the weight from the label, and pick the day and time you want to eat. Your roasting time and schedule update instantly.

HOW TO USE THE TURKEY CALCULATOR

I built this calculator for the busiest cooking day of the year, so it asks for as little as possible. Here is how to get your plan in under a minute.

1. Pick Turkey and the cut. Choose a whole turkey, a bone-in breast or a boneless breast. Tick "Stuffed bird" if you plan to cook stuffing inside it.
2. Enter the weight. Use the weight printed on the label. Fractions like 14 ½ work, and you can switch to kilograms and Celsius at the top.
3. Choose your oven type. If your oven has a fan or convection setting and you plan to use it, choose Fan. The calculator lowers the temperature and shortens the time for you.
4. Set when you want to eat. Pick the date and time dinner should hit the table, not the time you want to start cooking.
5. Follow the schedule. You get a timeline for preheating, putting the turkey in, checking the temperature, taking it out, resting and carving. Tap "Add to calendar" and your phone reminds you at every step.

The other tabs help with the jobs that come before roasting. "How much to buy" tells you what size turkey to get for your guest list, and "Thawing time" gives you the exact day to move it from the freezer to the fridge.

HOW LONG TO COOK A TURKEY

The standard method is to roast a turkey at 325°F (165°C) until the thickest parts reach 165°F (74°C). These are the time ranges the USDA recommends for a whole turkey at that temperature, and they are what the calculator uses.

Unstuffed Turkey at 325°F

• 8 to 12 lb: 2¾ to 3 hours
• 12 to 14 lb: 3 to 3¾ hours
• 14 to 18 lb: 3¾ to 4¼ hours
• 18 to 20 lb: 4¼ to 4½ hours
• 20 to 24 lb: 4½ to 5 hours

Stuffed Turkey at 325°F

• 8 to 12 lb: 3 to 3½ hours
• 12 to 14 lb: 3½ to 4 hours
• 14 to 18 lb: 4 to 4¼ hours
• 18 to 20 lb: 4¼ to 4¾ hours
• 20 to 24 lb: 4¾ to 5¼ hours

Notice that these are ranges, not exact times. Every oven runs a little differently, a turkey that went in cold from the fridge takes longer than one that sat out briefly, and a dark roasting pan browns faster than a shiny one. That is why the calculator tells you when to start checking the temperature as well as when the turkey should be done at the latest. Your thermometer always has the final word.

HOW BIG A TURKEY DO I NEED?

The simple rule I use is 1 pound of raw turkey per adult. That sounds like a lot, but a whole turkey is heavy with bones, so 1 pound gives each person a generous plate of meat. If you want leftovers for sandwiches and turkey soup, and in my house we always do, plan on 1½ pounds per adult. Children usually eat about half as much.

• 4 to 6 guests: 6 to 9 lb, or a bone-in turkey breast for a smaller group.
• 8 to 10 guests: 10 to 15 lb.
• 12 to 14 guests: 14 to 20 lb.
• 16 or more guests: 20 lb and up, or two smaller turkeys.

For a crowd, I strongly prefer two 12 to 14 pound turkeys over one 24 pounder. Two smaller birds roast in less time, cook more evenly, and give you twice as many drumsticks. The "How much to buy" tab does the math for you, then sends the weight straight to the cooking time calculator.

HOW TO THAW A TURKEY SAFELY

This is where my first Thanksgiving went wrong, so please do not skip it. A frozen turkey needs far more time to thaw than most people expect, and thawing it on the counter is not safe. The outside warms up into the temperature range where bacteria grow quickly, while the center is still frozen solid.

In the Refrigerator (Best Method)

Allow about 1 day in the fridge for every 4 to 5 pounds of turkey. A 16 pound turkey needs about 4 days, and a 20 pound turkey needs about 5. Keep it in its wrapping on a tray to catch drips, on the bottom shelf. A thawed turkey can stay in the fridge for another 1 to 2 days, so starting a day early is the safer choice. The Thawing time tab gives you the exact date to start based on when you plan to cook.

In Cold Water (Faster)

If you are short on time, submerge the turkey, still in a leak-proof bag, in a sink or cooler of cold tap water. Allow 30 minutes per pound, and change the water every 30 minutes so it stays cold. A 14 pound turkey takes about 7 hours. A turkey thawed this way must be cooked right away.

If You Forgot to Thaw It

You can roast a turkey straight from frozen. It is safe, but it takes about 50% longer than a thawed bird. Pull out the neck and the bag of giblets with tongs as soon as they loosen, usually about halfway through cooking. It is not the way I would choose to cook a turkey, but it beats eating at 8 o'clock at night.

HOW TO TELL WHEN YOUR TURKEY IS DONE

A good instant-read thermometer is the most important tool for Thanksgiving. You can find a reliable one for under $20, and it removes all the guesswork. A turkey is safe to eat when it reaches 165°F (74°C) in three places:

• The thickest part of the thigh, pushed in near the body but not touching the bone.
• The thickest part of the breast, inserted from the side toward the center.
• The innermost part of the wing, where it joins the body.

If the turkey is stuffed, the center of the stuffing must also reach 165°F. Many turkeys come with a plastic pop-up timer. I do not rely on them, because they often pop late, after the breast has dried out. Clear juices and wiggly legs are old signs that something is close, but they are not proof of safety. Only the thermometer tells you for sure.

One thing I learned from testing: the breast usually reaches 165°F before the thighs. If your breast is done and the thighs are not, cover the breast loosely with foil to protect it and let the thighs catch up.

HOW I PREPARE MY TURKEY

A few small steps the day before make a big difference on Thanksgiving morning.

• Remove the neck and giblets. Check both the main cavity and the neck cavity. Save the neck for gravy if you like.
• Do not wash the turkey. Rinsing raw poultry splashes bacteria around your sink and counters without making the bird any cleaner. Pat it dry with paper towels instead.
• Dry brine for juicier meat. Rub the turkey all over with kosher salt the day before, about 1 tablespoon of Diamond Crystal per 4 to 5 pounds, and leave it uncovered in the fridge overnight. The skin dries out and roasts up crisp.
• Skip brining if your turkey is pre-salted. Kosher and "self-basting" or "enhanced" turkeys already contain salt. Brining them again makes the meat too salty.
• Butter under the skin. Gently loosen the breast skin with your fingers and spread softened butter mixed with herbs underneath.

My family's favorite twist is a Pakistani-style masala butter. I mix softened butter with ginger-garlic paste, a little garam masala, cumin, paprika and lemon zest, and rub it under the skin. The kitchen smells like my mother's house, and Zainab says it is the only turkey she will eat without gravy. The cooking time stays exactly the same.

STUFFED OR UNSTUFFED?

A stuffed turkey takes longer to cook, and the stuffing must reach 165°F in its center to be safe. By the time the stuffing gets there, the breast meat can be overcooked. For that reason, I bake my stuffing in a separate dish and fill the turkey cavity with an onion, a lemon, a few garlic cloves and some herbs instead. The bird cooks faster and more evenly, and the stuffing gets crispy edges that everyone fights over.

If stuffing inside the bird is your family tradition, that is fine. Stuff it loosely right before it goes into the oven, never the night before, and tick "Stuffed bird" in the calculator so it adds the extra time.

RESTING AND CARVING

Once your turkey reaches 165°F, take it out and let it rest, loosely covered with foil, for 20 to 40 minutes before carving. Resting lets the juices settle back into the meat, so they end up on the plate instead of the cutting board. A large turkey stays hot for a long time, so do not worry about it going cold.

This resting window is also your secret weapon on Thanksgiving. With the turkey out of the oven, you can turn up the heat for sides like crispy garlic parmesan potato wedges or warm a basket of garlic knots while you make the gravy.

1. Remove the legs by cutting through the skin between the leg and body, then pull the thigh away and cut through the joint.
2. Separate the drumsticks from the thighs at the joint, then slice the thigh meat off the bone.
3. Cut along one side of the breastbone and work the knife down along the ribs to remove each breast half in one piece.
4. Slice the breast crosswise into thick slices so every piece has a bit of skin.
5. Remove the wings at the joint and arrange everything on a warm platter.

CONVECTION OVENS AND OTHER QUESTIONS

A convection, or fan, oven circulates hot air, so it roasts faster and browns more. If you use the fan setting, lower the temperature by 25°F, to 300°F, and start checking about 30 to 45 minutes earlier than a regular oven. The calculator does this automatically when you choose Fan.

If you roast your turkey in an oven bag, follow the time chart on the bag's package, because bags trap steam and cook faster. And if you live at a high altitude, expect cooking to take a little longer, so begin earlier and rely on your thermometer.

MY THANKSGIVING DAY TIMELINE

Here is the real schedule I follow for a 14 pound unstuffed turkey with dinner at 4 o'clock. Your exact times will appear in the calculator when you enter your own weight and dinner time.

The Day Before

• Make the cranberry sauce and any desserts, like coffee cake for Thanksgiving breakfast or a batch of eggnog snickerdoodles.
• Remove the giblets, pat the turkey dry and dry brine it. Leave it uncovered in the fridge.
• Set the table, so the morning stays calm.

Thanksgiving Day

• 11:05 am: Preheat the oven to 325°F. Rub the turkey with butter.
• 11:25 am: Put the turkey in the oven.
• 2:25 pm: Start checking the temperature every 10 to 15 minutes.
• 3:10 pm: Take the turkey out when it reads 165°F at the latest, and cover loosely with foil.
• 3:10 to 3:50 pm: Rest the turkey. Make the gravy and bake the sides.
• 3:50 pm: Carve.
• 4:00 pm: Dinner.

If the turkey is done early, that is good news. Keep it covered and it will stay hot for up to an hour, which gives you breathing room if guests are late.

STORING TURKEY LEFTOVERS

Get leftovers into the fridge within 2 hours of the turkey coming out of the oven. Carve all the meat off the bones first, because a whole carcass cools too slowly. Store it in shallow containers and eat it within 3 to 4 days, or freeze it for up to 2 to 6 months for the best quality. Reheat leftovers to 165°F.

My family looks forward to the leftovers almost as much as the dinner itself. We make turkey sandwiches on soft rolls, a quick turkey karahi with tomatoes and green chilies, and a big pot of soup from the carcass. If you need more ideas for the cozy week after Thanksgiving, my fall dinner recipes are full of easy meals that use up what is left.

FREQUENTLY ASKED QUESTIONS

These are the turkey questions I hear most every November.

How long does it take to cook a 15 pound turkey?

An unstuffed 15 pound turkey takes about 3¾ to 4¼ hours at 325°F. A stuffed 15 pound turkey takes about 4 to 4¼ hours. Start checking the temperature at the early end of the range and take it out when the thigh, breast and wing all read 165°F.

How many minutes per pound do you cook a turkey?

At 325°F, plan on roughly 13 to 15 minutes per pound for an unstuffed turkey and 15 to 17 minutes per pound for a stuffed one. Larger turkeys take fewer minutes per pound than small ones, so a weight-based chart or calculator is more accurate than a single per-pound rule.

What temperature should turkey be cooked to?

Turkey is safe at 165°F (74°C), measured in the thickest part of the thigh, the thickest part of the breast and the innermost part of the wing. If the turkey is stuffed, the center of the stuffing must also reach 165°F.

Should I cook my turkey at 325 or 350?

325°F is the USDA-recommended oven temperature and gives the most even results for a whole turkey. A slightly hotter oven, such as 350°F, cooks a little faster but can dry out the breast before the thighs are done.

How long does it take to thaw a turkey?

Allow about 1 day in the refrigerator for every 4 to 5 pounds, so a 16 pound turkey needs about 4 days. In cold water, allow 30 minutes per pound and change the water every 30 minutes.

Can I cook a turkey that is still frozen?

Yes. It is safe to roast a turkey from frozen, but it takes about 50% longer than a thawed turkey. Remove the neck and giblets with tongs once they loosen during cooking.

How long should a turkey rest before carving?

Rest a whole turkey for 20 to 40 minutes, loosely covered with foil. This keeps the meat juicy and gives you time to make gravy and finish the side dishes.

How much turkey do I need per person?

Plan on 1 pound of raw whole turkey per adult, or 1½ pounds per adult if you want leftovers. Children usually eat about half as much.
