Thanksgiving Leftovers: How Long They Last and When to Freeze

Thanksgiving leftovers are good for 3 to 4 days in the fridge, according to USDA food safety guidance. For a Thursday dinner, that means Monday is the last day. Anything you will not eat by then should go in the freezer before it.

The other rule matters even more: get the food into the fridge within 2 hours of the meal. Here is a simple plan for both.

Key takeaways

• Refrigerate leftovers within 2 hours. Within 1 hour if the room is above 90°F.
• Eat them within 3 to 4 days. For Thanksgiving on November 26, that is Monday, November 30.
• Reheat to 165°F, and freeze what you will not finish by Monday.

How long can food sit out after dinner?

Two hours is the limit. USDA guidance says perishable food should not sit at room temperature longer than that. Bacteria grow fastest between 40°F and 140°F, which is exactly where a cooling table sits.

A long, slow dinner is how most people go over. A useful habit: set a phone timer for 2 hours when the turkey comes out of the oven. When it rings, the food goes away, even if people are still talking.

How to pack leftovers so they cool fast

1. Use shallow containers. A deep pot of stuffing cools slowly in the middle. Split it into containers a few inches deep so the cold reaches all of it.
2. Take the meat off the bone. Carve the rest of the turkey into slices or pieces. A whole carcass takes up space and cools unevenly.
3. Leave a little room in the fridge. Cold air has to move around the containers. A packed shelf keeps them warm longer.
4. Label each one with the day. Write "Thu" on a strip of tape. On Sunday you will not remember which container came from which meal.
5. Keep your fridge at 40°F or below. A cheap fridge thermometer tells you for sure. This is the number the 3 to 4 day rule assumes.

What to eat first, and what to freeze

You will not eat everything by Monday, so decide on Friday morning.

• Eat first: gravy and anything with dairy, like mashed potatoes. These are the easiest to forget at the back of the fridge.
• Freeze early: turkey you will not eat by Sunday. Freeze it in meal sized bags so you only thaw what you need.
• Stuffing: it follows the same 3 to 4 day rule as the turkey. It also freezes well.
• Pie: pumpkin and other custard pies need the fridge too, not the counter.

Frozen leftovers stay safe for a long time, but taste best within a few months. USDA suggests roughly 2 to 6 months for the best quality.

How to reheat leftovers safely

Heat them to 165°F, checked with a food thermometer in the thickest part. Covering the dish keeps it moist and helps it heat all the way through.

• Gravy: bring it to a rolling boil.
• Microwave: stir halfway and let it stand a minute, since microwaves leave cold spots.
• Frozen leftovers: thaw them in the fridge overnight, or reheat straight from frozen. Do not thaw them on the counter.

The one rule that settles every doubt

If you cannot remember when something was cooked, or it has passed the 4 day mark, throw it out. You cannot smell or see the bacteria that cause food poisoning. "It looks fine" is not a test.
