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.
