Can Cooked Chicken Sit Out Overnight?
Last reviewed: May 2026
Quick answer
No. Cooked chicken left out overnight must be discarded. The USDA recommends refrigerating all cooked poultry within 2 hours of cooking (1 hour above 90°F/32°C). Overnight — 8 hours or more — far exceeds this limit for any preparation: rotisserie, grilled, fried, baked, or stewed. Reheating will not make it safe.
Bottom line: discard it
Cooked chicken left out overnight has far exceeded the USDA 2-hour safe limit. Discard it — reheating will not make it safe.
The USDA 2-hour rule for cooked chicken
The USDA recommends discarding all perishable cooked poultry left at room temperature for more than 2 hours. At temperatures above 90°F (32°C), that window shrinks to 1 hour. In the temperature danger zone between 40°F and 140°F (4°C–60°C), bacteria such as Salmonella, Campylobacter, and Staphylococcus aureus can double roughly every 20 minutes. See the official food-safety sources used by StillSafeFood for references.
This rule applies to all cooked chicken preparations — whole roasted chicken, rotisserie chicken, grilled chicken breasts, fried chicken, chicken wings, shredded chicken, and chicken in sauces or casseroles.
Why overnight is especially risky for poultry
Chicken is one of the most susceptible proteins to bacterial contamination. Even fully cooked chicken that is allowed to cool slowly at room temperature can develop unsafe bacterial levels during the hours spent between 140°F and 40°F. By the time chicken has been out all night, it has passed through the danger zone multiple times and spent hours within it.
Why reheating doesn't help
Reheating chicken to a safe temperature will kill most live bacteria but will not destroy the heat-stable toxins that bacteria such as S. aureus may have already produced during overnight exposure. Those toxins can cause illness regardless of how thoroughly the chicken is reheated.
Safe chicken storage
- Refrigerate cooked chicken within 2 hours of cooking (1 hour above 90°F).
- Store in a shallow, airtight container at or below 40°F (4°C).
- Consume refrigerated cooked chicken within 3–4 days.
- Freeze portions you will not eat within 3–4 days.
Frequently asked questions
Can cooked chicken sit out overnight?
No. Cooked chicken left out overnight must be discarded. Overnight far exceeds the USDA 2-hour safe limit for all cooked poultry.
Is cooked chicken safe if it was kept covered overnight?
No. Covering does not prevent bacterial growth. The USDA 2-hour rule applies whether chicken was covered, wrapped, or in a sealed container.
Can I reheat chicken left out overnight to make it safe?
No. Reheating kills bacteria but not the heat-stable toxins they may have produced. Discard cooked chicken left out overnight.
