Thanksgiving leftovers that you will not eat within 3 to 4 days should go into the freezer after they have cooled. The USDA leftovers and food safety page says leftovers can be frozen for 3 to 4 months for best quality. Frozen food held at 0°F stays safe longer than that, but texture and flavor fade. Turkey-specific USDA pages used on how long Thanksgiving leftovers last list about 4 months for plain turkey pieces and up to about 4 to 6 months for dishes, stuffing, and gravy. Treat those as quality windows, not a reason to keep mystery bags for a year.
Quality times, not a safety cliff
| Food | Freezer at 0°F, best quality |
|---|---|
| Cooked turkey, plain slices or pieces | About 4 months on turkey-specific USDA pages; the general leftovers page lists 3 to 4 months |
| Turkey with broth or gravy; cooked dishes, stuffing, and gravy | About 4 to 6 months for quality on turkey-specific USDA pages |
| Leftover cooked ham (spiral-cut or consumer-cooked leftovers) | 1 to 2 months for quality, per the USDA ham storage chart |
Wrap food tightly. Air is what dries leftovers and leads to freezer burn. Slice turkey, pack it in portions you will actually reheat, and press air out of bags. Gravy and soup freeze well in lidded containers with a little headspace. For which sides freeze well or poorly, use can you freeze leftover gravy and sides rather than assuming every casserole will thaw nicely.
Thaw safely, or reheat from frozen
USDA lists three safe thawing methods: the refrigerator, cold water, and the microwave. Refrigerator thawing is the most hands-off. Keep the package on a plate, and use the thawed leftovers within 3 to 4 days, or see whether you can refreeze leftover turkey. Cold-water thawing is faster, but the food must be in a leak-proof bag and should be cooked before you refreeze it. If you thaw leftovers in the microwave, continue heating until they reach 165°F. It is also safe to reheat frozen leftovers without thawing; they will just take longer.
Reheat to 165°F
However you start, leftover turkey, stuffing, and mixed dishes need to reach 165°F in the center. Sauces, soups, and gravy should come to a rolling boil. Cover the food so it heats evenly and stays moist. For turkey specifically, how to reheat leftover turkey covers oven and microwave methods. Pumpkin pie has its own rules; see can you freeze pumpkin pie and how long pumpkin pie lasts.
