How Long to Thaw a Turkey: Chart, Calculator and Timeline
USDA turkey thawing times by weight (fridge and cold water), how big a turkey you need, roasting times at 325°F and a Thanksgiving timeline.
The most common Thanksgiving mistake happens days before the meal: starting to thaw the turkey too late. A big frozen bird needs most of a week in the refrigerator. This guide gives you the USDA thawing times by weight, the three safe ways to thaw, the roasting timetable, and a simple timeline to work backward from dinner.

The short answer
According to the USDA:
- In the refrigerator: about 24 hours for every 4 to 5 pounds, at 40°F or below.
- In cold water: about 30 minutes per pound, changing the water every 30 minutes.
- In the microwave: follow your microwave's instructions for the weight, and cook the turkey immediately afterward.
Never thaw a turkey on the counter. The outside warms into the temperature range where bacteria multiply quickly, long before the inside thaws.
Refrigerator thawing times by weight
This is the easiest and safest method, and the one to plan around.
| Turkey weight | Days in the refrigerator |
|---|---|
| 4 to 12 lb | 1 to 3 days |
| 12 to 16 lb | 3 to 4 days |
| 16 to 20 lb | 4 to 5 days |
| 20 to 24 lb | 5 to 6 days |
Keep the turkey in its wrapping on a tray or in a pan to catch drips, on the bottom shelf. Once thawed, it can stay in the refrigerator for 1 to 2 days before cooking, so starting a day early is a safe buffer.
Example: a 16-pound turkey for Thursday dinner needs about 4 days. Put it in the refrigerator by Sunday, or Saturday for a spare day.
Cold water thawing times by weight
Running late? Cold water is much faster but needs attention.
| Turkey weight | Hours in cold water |
|---|---|
| 4 to 12 lb | 2 to 6 hours |
| 12 to 16 lb | 6 to 8 hours |
| 16 to 20 lb | 8 to 10 hours |
| 20 to 24 lb | 10 to 12 hours |
How to do it safely:
- Keep the turkey in its original, leak-proof wrapping (or put it in a leak-proof bag).
- Submerge it completely in cold tap water, breast side down, in a clean sink or cooler.
- Change the water every 30 minutes so it stays cold.
- Cook the turkey immediately after it thaws.
A 20-pound turkey needs about 10 hours this way, so it's a rescue plan, not a relaxing one.
Can you cook a turkey from frozen?
Yes. The USDA says a turkey can be cooked from frozen; it just takes about 50% longer than a thawed one. You'll need to remove the giblet package with tongs partway through cooking, once it loosens. This is the fallback if the thaw simply didn't happen.
How big a turkey do you need?
A common rule of thumb is about 1 pound of whole turkey per person, or 1.5 pounds per person if you want leftovers. The weight includes the bones, so it's more than the meat each person eats.
| Guests | About 1 lb each | With leftovers (1.5 lb each) |
|---|---|---|
| 6 | 6 to 8 lb | 9 lb |
| 8 | 8 lb | 12 lb |
| 10 | 10 lb | 15 lb |
| 12 | 12 lb | 18 lb |
| 16 | 16 lb | 24 lb |
For more than about 16 people, two smaller turkeys can be easier: they thaw and cook faster than one giant bird.
Roasting times at 325°F
The USDA timetable for a whole turkey in a 325°F oven:
| Weight | Unstuffed | Stuffed |
|---|---|---|
| 8 to 12 lb | 2¾ to 3 hours | 3 to 3½ hours |
| 12 to 14 lb | 3 to 3¾ hours | 3½ to 4 hours |
| 14 to 18 lb | 3¾ to 4¼ hours | 4 to 4¼ hours |
| 18 to 20 lb | 4¼ to 4½ hours | 4¼ to 4¾ hours |
| 20 to 24 lb | 4½ to 5 hours | 4¾ to 5¼ hours |
These are estimates. The turkey is done when a food thermometer reads at least 165°F in the innermost part of the thigh and wing and the thickest part of the breast. For best safety, the USDA recommends cooking stuffing separately; if you do stuff the bird, the center of the stuffing must also reach 165°F. Let the turkey rest about 20 minutes before carving, so the juices settle.
An instant-read thermometer is the single most useful tool for the day, and a sturdy roasting pan with a rack makes lifting a heavy bird much easier.
A Thanksgiving turkey timeline
Work backward from when you want to eat. For a 16-pound unstuffed turkey and a 4:00 pm Thursday dinner:
| When | What |
|---|---|
| Saturday or Sunday | Move the frozen turkey to the refrigerator |
| Wednesday | Check it's thawing; prep sides, bake pies |
| Thursday, 10:30 am | Turkey in a 325°F oven (4¼ hours max + rest + spare time) |
| From about 2:15 pm | Start checking the temperature |
| When it reads 165°F | Out of the oven to rest 20 minutes; bake sides |
| 4:00 pm | Carve and serve |
Our turkey planner builds this timeline for your turkey's weight and your dinner time.
After dinner: leftovers
- Refrigerate leftovers within 2 hours.
- Carve the meat off the bone and store it in shallow containers so it cools quickly.
- Eat refrigerated leftovers within 3 to 4 days, or freeze them.
- Reheat leftovers to 165°F.
Plan the whole meal, not just the bird
The turkey is the item with the longest lead time, but it's not the only one. Our printable Thanksgiving dinner planner includes a 4-week countdown, guest and menu planners, a shopping list by store section, an oven schedule so dishes don't collide, the USDA thawing and roasting tables, and a day-of timeline. Print it, put it on the fridge, and Thursday runs itself.
