How to cook a frozen turkey without thawing
Short answer: you can roast a turkey straight from the freezer. USDA says it is safe and takes "at least 50 percent longer" than a thawed one. A 12 to 14 lb bird that needs up to 3 h 45 min thawed needs at least 5 h 40 min frozen at 325 °F (163 °C). It is done when a food thermometer reads 165 °F (74 °C).
If the thaw window already slipped past you, this page is for that. The table below is USDA's roasting table for unstuffed whole turkeys with each time multiplied by 1.5 and rounded up to the next 5 minutes. Treat the frozen column as a minimum. Your bird may take longer, so plan a buffer and let the thermometer decide.
Thawed against frozen, by weight
| Weight | Thawed (USDA) | Frozen, at least | Extra time, long end |
|---|---|---|---|
| 8 to 12 lb | 2 h 45 min to 3 h | 4 h 10 min to 4 h 30 min | +1 h 30 min |
| 12 to 14 lb | 3 h to 3 h 45 min | 4 h 30 min to 5 h 40 min | +1 h 55 min |
| 14 to 18 lb | 3 h 45 min to 4 h 15 min | 5 h 40 min to 6 h 25 min | +2 h 10 min |
| 18 to 20 lb | 4 h 15 min to 4 h 30 min | 6 h 25 min to 6 h 45 min | +2 h 15 min |
| 20 to 24 lb | 4 h 30 min to 5 h | 6 h 45 min to 7 h 30 min | +2 h 30 min |
Oven at 325 °F, unstuffed. The thawed column is the USDA turkey roasting time chart. The brochure has no frozen chart of its own, so the frozen column is my arithmetic on its sentence. A 20 to 24 lb frozen bird can take up to 7½ hours, so the big ones need an early start.
What USDA says to do differently
- Giblets: "Remember to remove the giblet packages during the cooking time. Remove carefully with tongs or a fork." The packet is frozen into the cavity, so it comes out partway through, once the bird has softened.
- Thermometer: for a whole turkey, put it in the thickest part of the inner thigh. Once the thigh reads 165 °F, check the wing and the thickest part of the breast too. All three spots need 165 °F.
- Rest: USDA suggests letting the turkey stand 20 minutes before carving. The planner keeps a 30 minute rest, so a bird that runs long still has slack.
I add no advice of my own here. The figures are from the USDA FSIS brochure "Let's Talk Turkey". That site blocks my tools, so I read the same text in a University of Wisconsin Extension copy, opened on October 15, 2026.
When to put it in for dinner
Take a 12 to 14 lb turkey, dinner at 5 PM and a 30 minute rest, so it comes out at 4:00 PM. A thawed bird at the long end of USDA's range goes in at 12:15 PM. A frozen one goes in at 10:20 AM, planned on the 5 h 40 min floor. Add buffer on top, because "at least" has no upper limit.
The sides keep their own times, but the turkey holds the oven longer, so they move later in the day. The planner works that out. Open the one-oven menu with the turkey set to 5 h 40 min, then change the turkey's cook time to your weight from the table. For another menu, add the last column to your turkey's cook time and every start time moves with it.
