How Long Do Thanksgiving Leftovers Last?
The food safety numbers from university extension services and a state health department, with a Thursday-to-Monday countdown and the one leftover that runs out first.

Refrigerate leftovers within 2 hours of cooking (1 hour if it is above 90°F), and use turkey and stuffing within 3 to 4 days or freeze them. Use leftover gravy within 1 to 2 days, the shorter limit some health agencies give. Reheat everything to 165°F on a food thermometer, and bring gravy to a rolling boil.
The 2-hour rule
University of Georgia Extension says to cut the turkey into small pieces and refrigerate the turkey, stuffing and gravy separately in shallow containers within 2 hours of cooking, or within 1 hour when it is above 90°F. The clock starts when the food comes off the heat, not when dinner ends.
The Minnesota Department of Health is blunt about the other side: throw away turkey, stuffing and gravy left at room temperature longer than 2 hours. University of Illinois Extension adds a trick for big batches: divide them into smaller containers, stir, and set them in an ice bath to cool faster.
3 to 4 days, and gravy runs out first
UGA Extension and Illinois Extension both say to use refrigerated leftovers within 3 to 4 days. For a Thursday dinner, that means Sunday, Monday at the very latest. K-State Research and Extension says not to wait until day four to freeze turkey you will not finish.
Gravy is where the sources split. UGA groups it with turkey and stuffing at 3 to 4 days, but the Minnesota Department of Health and K-State both say to use gravy within 1 to 2 days. We go with the shorter number: Thursday's gravy is gone by Saturday. K-State also gives casseroles and cooked vegetables 2 to 3 days.
Freezing: safe for good, best within months
K-State says food that is safe when it goes into the freezer is safe when it comes out, so the freezer times you see are about quality. UGA says to use frozen leftovers within 2 to 6 months for best quality; Illinois Extension and K-State give 3 to 4 months for meat and poultry dishes. Date and label each container.
UGA says it is safe to refreeze leftover turkey and trimmings even if the turkey was bought frozen. K-State says frozen leftovers can be reheated without thawing; it just takes longer. Our leftover turkey tetrazzini and turkey carcass noodle soup both use up a lot of turkey before the deadline.
Reheat to 165°F, boil the gravy
UGA and Illinois Extension both say to reheat leftovers to 165°F, checked with a food thermometer. K-State adds that sauces, soups and gravies should come to a rolling boil.
In the microwave, K-State says to cover the food, add a little liquid if needed, vent the lid, rotate the dish, and check the temperature in several places, because microwaves leave cold spots. A Kentucky Hot Brown or a diner hot turkey sandwich does both jobs in one plate. Still planning the bird? See how long to thaw a turkey.
Questions people ask
Is turkey that sat out overnight safe to eat?
No. The Minnesota Department of Health says to throw away turkey, stuffing and gravy left at room temperature longer than 2 hours, or 1 hour above 90°F.
Can I refreeze leftover turkey?
Yes. UGA Extension says leftover turkey and trimmings can be refrozen, even if the raw turkey was bought frozen. Wrap them tightly for the best quality.
How long do the side dishes last?
UGA gives stuffing 3 to 4 days. K-State gives casseroles and cooked vegetables 2 to 3 days, so eat the green bean casserole first.
Do I have to thaw frozen leftovers before reheating?
No. K-State says frozen leftovers can go straight into a saucepan, the oven or the microwave. It takes longer, and the food still needs to reach 165°F.
