Leftover Reheating Time & Temp Calculator

USDA guidance recommends reheating leftovers to an internal temperature of 165°F, checked with a food thermometer, regardless of the method used.

Microwaves heat food by exciting moisture, which tends to make breading and fried coatings soggy rather than crisp — an oven or stovetop pan does a much better job of restoring crispness.

Food safety guidance generally advises reheating leftovers only once; repeated cooling and reheating cycles increase the opportunity for bacterial growth. Reheat only the portion you plan to eat.
