Leftovers: fridge within 2 hours, eat within 3 to 4 days
USDA’s leftovers advice comes down to three numbers. Get cooked food into the fridge within 2 hours, or 1 hour when it’s above 90 °F. Eat it within 3 to 4 days. Reheat it to 165 °F. Anything you won’t finish in time can go in the freezer.
Our take: split leftovers into shallow containers as soon as the meal is over, write the date on the lid, and freeze whatever you won’t eat within 3 days. Count days instead of sniffing: FDA says food can make you sick without looking or smelling spoiled. [S1] [S5]
Three numbers for leftovers
Into the fridge within 2 hours
Bacteria grow fastest between 40 °F and 140 °F, the range USDA calls the Danger Zone, and they can double in as little as 20 minutes. That’s why cooked food shouldn’t sit out for more than 2 hours, or more than 1 hour when it’s above 90 °F, like at a summer picnic or in a hot car. USDA says to throw away perishable food left out longer than that. [S1] [S2] [S4]
The clock starts when the food is done cooking or comes off a warming tray or slow cooker. FDA says the same 2 hours apply to doggie bags and takeout. [S1] [S5]
Cool it fast. A big pot of soup takes a long time to cool, so USDA says to divide large amounts into shallow containers. Slice roasts and hams, and cut a turkey into smaller pieces: slice the breast, and leave the legs and wings whole. Hot food can go straight into the fridge, or into an ice or cold-water bath first. Cover it, wrap it airtight or seal it in a container. [S1]
Leave room for cold air to move around the shelves, and keep the fridge at 40 °F or below and the freezer at 0 °F, checked with an appliance thermometer. [S4] [S5] Our fridge thermometer guide walks through that check.
3 to 4 days in the fridge
USDA says leftovers keep 3 to 4 days in the refrigerator. FoodSafety.gov’s storage chart gives the same 3 to 4 days for cooked meat and poultry, soups and stews, pizza, chicken nuggets, casseroles with eggs, and egg, chicken, ham, tuna and macaroni salads. [S1] [S3]
Counting days beats a sniff test. FDA explains that the bacteria that cause illness are different from the ones that spoil food, so leftovers can make you sick even when they look, smell and taste fine. [S5]
Pick the date to see when USDA’s 3 to 4 days run out.
Choose a food to highlight its storage times below.
Fridge: 3 to 4 days. Freezer: 2 to 6 months for best quality. [S3]
Fridge: 3 to 4 days. Freezer: 2 to 3 months for best quality. [S3]
Fridge: 3 to 4 days. Freezer: 1 to 2 months for best quality. [S3]
Fridge: 3 to 4 days. Freezer: 1 to 3 months for best quality. [S3]
Fridge: 3 to 4 days. The chart says these don’t freeze well. [S3]
Fridge: 3 to 4 days after baking. Freezer: 2 to 3 months after baking. [S3]
USDA’s general rule: 3 to 4 days in the fridge, or 3 to 4 months in the freezer for best quality. [S1]
Freeze it for longer, thaw it safely
Leftovers kept frozen stay safe indefinitely, USDA says. The freezer times are about quality, since frozen leftovers slowly lose moisture and flavor. Freezing doesn’t kill germs, though; it holds food safe until you cook it. FDA adds that freezer burn hurts quality, not safety. [S1] [S3] [S4] [S5]
Where the pages differ
USDA’s leftovers page gives one freezer number for leftovers: 3 to 4 months. FoodSafety.gov’s chart breaks it down by food, from 1 to 2 months for pizza to 2 to 6 months for cooked meat and poultry, and says egg, chicken, ham, tuna and macaroni salads don’t freeze well. Both say these freezer times are for quality only. We’d use the chart’s row when your food has one, and USDA’s 3 to 4 months for everything else. [S1] [S3]
- Fridge thawing. It takes longest, but the food stays safe the whole time. Use it within 3 to 4 days, or refreeze it. [S1]
- Cold-water thawing. Keep the leftovers in a leak-proof bag, and cook them before refreezing. [S1]
- Microwave thawing. Keep heating until it reaches 165 °F. After that, it can be refrozen. [S1]
- Straight from frozen. USDA says it’s safe to reheat frozen leftovers without thawing, in a saucepan, microwave or oven. It just takes longer. [S1]
- Not on the counter. FoodSafety.gov says never to thaw food on the counter. [S4]
Reheat to 165 °F
USDA says to reheat leftovers to 165 °F, measured with a food thermometer, and to bring sauces, soups and gravies to a rolling boil. Covering the food keeps it moist and helps it heat all the way through. [S1] [S2]
Microwaves leave cold spots. Cover the dish and rotate or stir the food partway through, let it stand, then check the temperature in several places. [S1] [S4] Our safe meat temperatures guide shows where to put the probe.
Reheated more than you can eat? USDA says food left over after reheating previously frozen leftovers to 165 °F is safe to refreeze. [S1]

Quick answers
Can hot food go straight into the fridge?
Yes. USDA says hot food can go directly into the refrigerator, or be chilled in an ice or cold-water bath first. Shallow containers help it cool quickly. [S1]
It still smells fine on day 5. Is it OK?
Smell won’t tell you. FDA says food can make you sick without looking, smelling or tasting spoiled, and USDA’s fridge window for leftovers is 3 to 4 days. Past that, throw it out. [S1] [S5]
Does the 2-hour rule cover takeout?
Yes. FDA says it applies to leftovers, doggie bags and takeout food. [S5]
What if the power went out?
FDA says an unopened fridge keeps food cold for about 4 hours, and a full freezer holds for about 48 hours. Throw out refrigerated perishable food, leftovers included, that sat above 40 °F for 4 hours or more. [S5]
Can I refreeze thawed leftovers?
It depends on how you thawed them. Leftovers thawed in the fridge can be refrozen without reheating. Cook cold-water-thawed food first, and heat microwave-thawed food to 165 °F before it goes back in the freezer. [S1]
Are products ranked here?
No. This guide explains federal food safety advice. It doesn’t rank or endorse any container, thermometer or appliance, and no products were tested for it.
