A holding cabinet includes a body defining a holding space and a holding compartment disposed within the holding space for holding a product therein. The holding cabinet further includes a heating source, a steam generator, a temperature sensor, a humidity sensor, a product detector, and a controller. The controller is configured to regulate environmental conditions of the holding compartment according to a determined setpoint, which corresponds to a predetermined temperature and relative humidity. The controller regulates such environmental conditions by acquiring the sensed air temperature, relative humidity, and the detected type of product, and activating and deactivating the heating source and the steam generator in accordance with the acquired air temperature, relative humidity, and the determined setpoint corresponding to the type of product detected and a holding time of the product, to maintain the air temperature and the relative humidity within a predetermined range based on the determined setpoint.
