How long does onion rings keep?
Refrigerated at or below 40°F in an airtight container, onion rings keeps about 3 days. If it has been at room temperature for more than 2 hours (1 hour above 90°F), discard it — reheating does not undo unsafe storage.
Can you reheat it twice?
USDA guidance allows reheating to 165°F each time, but every round trip costs texture and flavor. The better habit: reheat only the portion you'll eat.
