Thanksgiving falls on 26 November in 2026, and a frozen turkey needs days, not hours, to thaw safely. The three bodies that publish consumer guidance for this, the US Food and Drug Administration, the UK Food Standards Agency (FSA) and the University of Georgia Cooperative Extension, agree on the rules: never thaw on the counter, and use the refrigerator, cold water or the microwave. They also give the timings, which differ slightly depending on whether you count in pounds or kilograms.
Why the counter is not an option
The FDA’s holiday guidance says never to defrost food at room temperature. A turkey left on the worktop warms on the outside long before the centre is thawed, and harmful bacteria multiply quickly at room temperature. The FSA gives the same advice for Christmas birds in the UK: do not defrost at room temperature. It adds a second reason to finish the job properly. If the turkey is not fully defrosted before cooking, it may cook unevenly, so bacteria can survive the cooking process.
Method 1: the refrigerator (safest, slowest)
The University of Georgia Extension calls refrigerator thawing the safest method. For every 4 to 5 pounds of turkey, allow about 24 hours in a refrigerator set at 40°F (about 4°C). Its chart gives these times:
| Turkey size | Refrigerator thawing time |
|---|---|
| 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 |
The FDA gives a single example that fits the same chart: a 20-pound turkey needs four to five days to thaw completely in the refrigerator.
The FSA works in kilograms. It says a whole turkey can take between 3 and 5 days to defrost all the way to the middle, and that a typical large bird of 6 to 7 kg could take as much as 4 days. If the packaging has no instructions, it suggests allowing around 10 to 12 hours per kilogram in the fridge. Always follow the label on the bird you bought, because the FSA notes that a few turkeys can be cooked from frozen if the manufacturer says so.
Two handling points come up in both the UK and US guidance. Thaw the bird in a container, or a covered tray big enough to catch drips, so raw juices cannot reach other food, and put it on the bottom shelf. The FSA adds that you should wash your hands thoroughly with soap and warm water after touching raw turkey, and that raw turkey should not be washed, because washing spreads germs onto hands, clothes, utensils and worktops.
Once thawed in the refrigerator, the University of Georgia says the turkey can stay there for only 1 to 2 days before cooking, so work backwards from the day you plan to roast. A 16 to 20 lb bird needs 4 to 5 days, so moving it into the refrigerator on Friday 20 November leaves about a day of margin before a Thursday 26 November dinner.
Method 2: cold water (faster, needs attention)
If the bird is still frozen with less than a few days to go, the FDA says food can be defrosted safely under cold running water, and the University of Georgia describes a practical version. Keep the turkey in its airtight packaging or a leak-proof bag, submerge it in cold tap water, and allow about 30 minutes per pound. Change the water every 30 minutes so it stays cold; the cold water slows the multiplication of bacteria on the thawed outer parts while the inside is still thawing. Setting a timer helps. The university gives these times:
- 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
The FDA states that food thawed in cold water or in the microwave should be cooked immediately. A turkey thawed this way should go straight into the oven rather than back into the refrigerator to wait.
Method 3: the microwave (small birds only)
Microwave thawing depends on the oven. The University of Georgia says to follow the manufacturer’s instructions for the largest turkey that fits, the minutes per pound and the power level. Remove all outside wrapping, place the bird in a microwave-safe dish and use the defrost function based on weight. As a general guide it allows about 6 minutes per pound, rotating and flipping the turkey several times so it does not start to cook. Plan to cook it immediately afterwards. Most full-size turkeys will not fit in a household microwave, so this suits small birds and crowns.
After thawing: giblets and checks
Take the giblets out of the cavity once the bird has thawed and cook them separately. The FSA’s warning applies here: a bird that is not fully defrosted can cook unevenly.
What about cooking from frozen?
The FSA says some turkeys can be cooked from frozen, but only if the manufacturer’s instructions say so; most frozen turkeys need defrosting first. Read the label before relying on this, and plan for a longer oven time. Our guide to turkey roasting times by weight sets out the oven times and the safe internal temperature once the bird is ready.
A simple countdown for Thanksgiving week
- Check the weight on the label and find your bird in the refrigerator chart above.
- Count back from Thursday 26 November, allowing the full refrigerator time plus a spare day.
- Clear the bottom shelf and put a covered tray under the turkey.
- If time runs short, switch to cold water and cook the turkey as soon as it is thawed.
