Standing time is the rest period recommended after microwave cooking, during which the food stays in the switched-off oven — or is left covered on the counter — before serving. It matters for two reasons. First, heat keeps moving: microwaves heat unevenly, and during standing time conduction evens out hot and cold spots, so the food finishes cooking gently and reaches a uniform temperature. Second, it is a food-safety step, because cold spots may not have reached temperatures that destroy pathogens; the equalisation period lets residual heat complete the job. Packaging instructions often specify two to five minutes. Skipping standing time can mean the outside is scalding while the centre is still lukewarm.
