How Long Can Cooked Food Sit Out?
Last reviewed: June 2026
Quick answer
Most cooked perishable food should not sit out for more than 2 hours at room temperature. If the temperature is above 90°F, the limit is 1 hour. After that, the safer choice is usually to throw it away. Reheating does not reliably make food safe if it sat out too long.
Maximum: 2 hours at room temperature
All perishable cooked food must be refrigerated within 2 hours (1 hour if above 90°F). After that, discard it — even if it looks and smells fine.
The 2-hour rule for cooked food
The USDA recommends that all perishable cooked food be refrigerated within 2 hours of cooking or serving. See the official food-safety sources used by StillSafeFood for references.
The 1-hour rule above 90°F
When the ambient temperature is above 90°F (32°C) — such as at an outdoor cookout or in a hot kitchen — the safe window shrinks to just 1 hour. Past that point, the same discard guidance applies regardless of how the food looks or smells.
What counts as cooked perishable food?
This rule applies to all cooked perishable foods: chicken, beef, pork, fish, rice, pasta, eggs, soups, casseroles, and any dish containing these ingredients. If a food needs refrigeration when raw, it needs refrigeration after cooking too — cooking does not make a perishable food shelf-stable.
The danger zone: 40°F to 140°F
Bacteria thrive between 40°F and 140°F (4°C–60°C) — the USDA "danger zone." In this range, bacteria can double roughly every 20 minutes. At 2 hours, bacterial counts in some foods can reach levels high enough to cause illness. At 4+ hours, the risk increases significantly. Some bacteria also produce heat-stable toxins as a byproduct of growth. Reheating to 165°F (74°C) kills live bacteria but does not destroy these toxins — this is why "reheat it and it'll be fine" is not reliable food safety advice.
Hot holding vs. room temperature
Food held continuously at 140°F (60°C) or above — like a chafing dish or slow cooker on a buffet — stays out of the danger zone and isn't subject to the same 2-hour clock. Once food drops below 140°F and sits at room temperature, the standard 2-hour (1-hour above 90°F) rule applies from that point.
Can you reheat cooked food that sat out too long?
Not reliably. Reheating to 165°F (74°C) kills most live bacteria, but it does not destroy heat-stable toxins that bacteria such as Staphylococcus aureus and Bacillus cereus may have already produced. Reheating guidance applies to food that was stored safely, not food that already sat out too long. See does reheating make food left out safe for a full breakdown.
What if the food was covered?
Covering, wrapping, or sealing food in a container does not stop bacteria from multiplying at room temperature. Covered food past the 2-hour (1-hour above 90°F) limit is not safe — the rule applies the same way whether the food was left uncovered on the counter or sealed in a container.
What if the food was in a car, lunchbox, cooler, or picnic table?
A cooler with ice can extend safe storage time, but an insulated lunchbox or bag without ice does not reliably keep food below 40°F — treat it the same as counter storage. A parked car can heat up well past 90°F within minutes, dropping the safe limit to 1 hour. Food sitting on a picnic table follows ordinary room-temperature rules, and outdoor heat can push it past 90°F quickly. If you're not sure the food stayed cold, the safer choice is to discard it.
What if the food still smells fine?
Food left out too long can look, smell, and taste completely normal and still be unsafe. Many of the bacteria and toxins responsible for foodborne illness don't produce any noticeable smell or change in appearance. Go by how long the food was at room temperature, not by your senses.
Safe vs. not safe examples
Food left out 1 hour
Usually safe to refrigerate now, if room temperature was normal
Food left out 2 hours
Refrigerate immediately, or discard if unsure how long it sat out
Food left out overnight
Discard — far past the 2-hour limit
Food left in a hot car
Discard if it was over 90°F for more than 1 hour
Food refrigerated promptly
Use within 3–4 days
Food stored safely and reheated
Reheat to 165°F (74°C) until steaming throughout
How to cool cooked food safely
- Divide large portions into shallow containers so they cool quickly and evenly.
- Avoid stacking hot containers tightly together — leave room for air to circulate.
- Don't leave food out "to cool down first" — refrigerate within the 2-hour window instead.
- For soups or stews, an ice bath under the container can speed up cooling.
How to store cooked leftovers safely
- Refrigerate within 2 hours of cooking (1 hour above 90°F/32°C).
- Keep the refrigerator at or below 40°F (4°C) and the freezer at or below 0°F (-18°C).
- Store in airtight containers to prevent contamination and odor transfer.
- Label containers with the date so you know when they need to be used or discarded.
How long cooked leftovers are good in the fridge
Once refrigerated promptly, most cooked leftovers are good for 3–4 days:
Cooked chicken, turkey, beef, pork, fish
2 hours at room temp; 3–4 days in fridge
Cooked rice
2 hours at room temp; 3–4 days in fridge
Cooked pasta
2 hours at room temp; 3–5 days in fridge
Soups and stews
2 hours at room temp; 3–4 days in fridge
Pizza
2 hours at room temp; 3–4 days in fridge
Egg dishes
2 hours at room temp; 3–4 days in fridge
What to do after a power outage
If the power went out, the 2-hour rule still applies, but it's measured from when the fridge actually warmed past 40°F, not from when the power went out. A closed refrigerator generally holds for about 4 hours, and a full freezer for about 48 hours. See is food safe after a power outage for what to keep and what to throw away.

Food examples
Cooked poultry follows the same 2-hour / 3–4 day rules as other cooked food.
All cooked beef cuts follow the standard 2-hour (1-hour above 90°F) rule.
Carries a notable Bacillus cereus risk if it sits out too long.
Cheese and meat toppings are perishable — refrigerate within 2 hours.
Most cooked leftovers are good for 3–4 days once refrigerated promptly.
Perishable dairy follows the same 2-hour room-temperature rule as cooked food.
US refrigerated eggs follow the same 2-hour rule, raw or cooked.
Sliced deli and lunch meat are highly perishable — the same 2-hour rule applies.
Reheating to 165°F applies to safely stored food, not food left out too long.
A closed fridge holds for about 4 hours; a full freezer for about 48 hours.
This guidance follows USDA and FSIS food safety recommendations. Smell, taste, and appearance are not reliable ways to judge whether food left out too long is safe to eat — when in doubt, throw it out. If you think you may have food poisoning, contact a healthcare provider.
Frequently asked questions
How long can cooked food sit out at room temperature?
No more than 2 hours at room temperature (1 hour above 90°F/32°C), per USDA guidelines.
Can cooked food sit out for 3 hours?
No. Three hours exceeds the 2-hour limit. The safer choice is usually to discard it.
What if cooked food was covered while sitting out?
Covering does not stop bacterial growth. The 2-hour rule applies whether food was covered, wrapped, or sealed.
Can I reheat cooked food that sat out too long?
No. Reheating kills bacteria but not the toxins they may have already produced. Discard it instead.
What temperature should leftovers be reheated to?
165°F (74°C) until steaming hot throughout — for food that was stored safely.
What foods are most risky if left out?
Rice and pasta (Bacillus cereus risk), poultry, seafood, and dairy carry extra risk, but the 2-hour rule applies to all cooked perishable food.
Is food safe if it smells fine?
Not necessarily. Smell, taste, and appearance are not reliable safety tests — go by time and temperature instead.
How long can cooked food sit out in hot weather?
No more than 1 hour above 90°F (32°C) — shorter than the standard 2-hour window.
What should I do if cooked food was left out overnight?
Discard it. Overnight is far beyond the 2-hour (or 1-hour above 90°F) safe window.
