Del BaileyThanksgiving leftovers keep for 3 to 4 days in the refrigerator, according to the USDA Food Safety and Inspection Service (FSIS). Set the fridge to 40°F or below. Get them chilled within 2 hours of cooking. If you will not finish them by day four, freeze them. FSIS says frozen leftovers stay safe indefinitely but lose quality over time.

How long do Thanksgiving leftovers last in the fridge
I cook most nights, and I have packed up more holiday dinners than I can count. The cooking is rarely where things go wrong. It is the end of the night. Dinner runs long, dessert comes out, and the turkey sits on the platter until someone remembers it. The clock starts days earlier, when you thaw the turkey safely. It keeps running after the plates are cleared.
FSIS gives the same fridge window, 3 to 4 days, to leftovers in general and to stuffing in particular. Its general leftovers guidance also gives 3 to 4 months in the freezer. The cooked turkey and turkey soup rows use the FoodSafety.gov storage chart instead. All of it assumes a fridge at 40°F or below:
| Leftover | Refrigerator | Freezer (best quality) |
|---|---|---|
| Cooked turkey | 3 to 4 days | 2 to 6 months |
| Turkey soup | 3 to 4 days | 2 to 3 months |
| Stuffing | 3 to 4 days | 3 to 4 months |
| Gravy | 3 to 4 days | 3 to 4 months |
| Mashed potatoes and other cooked sides | 3 to 4 days | 3 to 4 months |
Freezer times are about quality, not safety. FSIS says frozen food stays safe indefinitely, but frozen leftovers can lose moisture and flavor when they sit too long.
Count from the night you cooked. For a Thursday dinner, four days runs out on Monday. Anything still in the fridge by then should already be eaten or frozen.
Treat day three as the decision point. Whatever has not been touched by then goes in the freezer, where FSIS says it stays safe indefinitely. Day four is the deadline, not the target.
How to store Thanksgiving leftovers
The 2-hour rule matters more than any other number on this page. FSIS says leftovers must be refrigerated within 2 hours of cooking, or of coming out of an appliance that keeps food warm. Perishable food left out longer should be thrown away. Cheese boards and other Thanksgiving snacks that are perishable fall under the same limit.
Heat shortens the window. FoodSafety.gov says food exposed to temperatures above 90°F, like a hot car, should be refrigerated within 1 hour. A casserole riding home in a warm car is on a one-hour clock. FSIS says to keep hot food at 140°F or warmer and cold food at 40°F or colder, and a buffet at room temperature sits in between.
Do not wait for food to cool on the counter. FSIS says hot food can go straight into the refrigerator. It also says to divide big batches into shallow containers so they chill quickly.
I put a strip of masking tape on every container and write the date on it. It takes ten seconds and settles the argument on day five about when something was cooked.
Break the turkey down before it goes in. FSIS says to cut a large turkey or roast into smaller pieces so it chills faster, slicing the breast and leaving the legs and wings whole.
How long does turkey last in the fridge
Cooked turkey keeps 3 to 4 days in the refrigerator, according to FSIS. Soup or a casserole made from it falls under the same general leftovers rule.
Carve the bird while the kitchen is still busy, not the next morning. Sliced turkey cools faster than a whole carcass, and it is ready for sandwiches, soup and easy weeknight meals. Every one of those dishes follows the same 3-to-4-day count.
How long does stuffing last in the fridge
Cooked stuffing keeps 3 to 4 days in the refrigerator, according to FSIS. Its stuffing guidance says to cool the stuffing in shallow containers and refrigerate it within 2 hours.
If the stuffing went inside the bird, FSIS says to let the bird stand 20 minutes and then take the stuffing out. Leftover stuffing or stuffed parts should be used or frozen within 3 to 4 days.
Do not put leftover stuffing back inside a whole bird, says FSIS. If you prep stuffing ahead, do not refrigerate it uncooked. To reheat cooked stuffing, bring it to 165°F in the microwave or in an oven set no lower than 325°F.
How long do mashed potatoes last in the fridge
FSIS has no separate time for mashed potatoes. They fall under its general leftovers rule of 3 to 4 days in the refrigerator. They also belong in shallow containers, not the deep bowl they were served in.
Gravy gets one extra rule. When you reheat gravy, sauces or soups, FSIS says to bring them to a rolling boil.
Green beans and other cooked sides run on the same general 3 to 4 days. A fridge shelf full of matching containers gets confusing by day three. That is what the date on the tape is for.
Can you freeze Thanksgiving leftovers
Yes. Freeze them promptly in shallow containers. FSIS gives leftovers in general 3 to 4 months in the freezer. The FoodSafety.gov chart allows cooked turkey 2 to 6 months and turkey soup 2 to 3 months.
Frozen leftovers stay safe indefinitely, but FSIS says they lose moisture and flavor the longer they sit. If the fridge clock is about to run out, freeze the container instead of gambling on day five.
FSIS lists three ways to thaw frozen leftovers:
- Refrigerator: the slowest method, but the leftovers stay safe the entire time.
- Cold water: use a leak-proof package, and cook the food before refreezing it.
- Microwave: heat the food until it reaches 165°F.
You can also skip thawing. FSIS says it is safe to reheat frozen leftovers without thawing them, though it takes longer.
How to reheat Thanksgiving leftovers
Reheat all leftovers to 165°F, measured with a food thermometer, per FSIS. It also says to cover the dish while it heats.
Gravy, sauces and soups go to a rolling boil. FSIS notes that dense food such as a whole turkey takes longer to heat through, so check the thickest part, not just the top.
In the microwave, FSIS says to vent the cover and rotate the dish. Check the temperature in several spots, and let the food rest before the final reading. Casseroles and one-pot meals can also be reheated in the oven.
Frequently asked questions about Thanksgiving leftovers
Can you eat Thanksgiving leftovers after 5 days?
FSIS says to use refrigerated leftovers within 3 to 4 days. A dish on day five is past that guidance. If you will not finish a container by then, freeze it sooner.
How long can Thanksgiving dinner sit out?
Two hours at most. FSIS says leftovers must be refrigerated within 2 hours of cooking. The limit is 1 hour if the temperature is over 90°F. Perishable food left out longer should be thrown away.
Do you have to let leftovers cool before refrigerating them?
No. FSIS says hot food can go straight into the refrigerator. It also says to divide large amounts into shallow containers so the food cools quickly.
Is it safe to reheat frozen leftovers without thawing?
Yes. FSIS says you can reheat frozen leftovers without thawing them, though it takes longer. They still need to reach 165°F, measured with a food thermometer.
Can you refreeze Thanksgiving leftovers?
FSIS says it is safe to refreeze leftovers that were reheated to 165°F after being frozen. Food thawed by the cold water method should be cooked before refreezing.
