Can it sit out?
Casseroles is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if casseroles has gone bad
- A sour or fermented smell when the foil comes off
- Mold on the top or creeping around the edge of the dish
- A slimy sheen across the sauce or noodles
- Liquid pooling that wasn’t there when it went in
When in doubt, throw it out.
Reheat to 165°F all the way through — a casserole heats unevenly, so stir or rotate it instead of trusting a hot rim.
