Preheat oven to 350°F

Remove the lid and place the stainless steel container on the middle rack of the oven.

Heat the dish for 10-15 minutes

Alternatively, transfer food to the microwave-safe dish and reheat in the microwave oven for 1-2 minutes or until hot. Do not place the steel container in the microwave oven as it will damage the oven and can cause fire hazard!
