Infrared radiation.
Only by radiation. Infrared waves waves don't require a material medium to pass through. Heat energy is transmitted even through vacuum in the form of infrared waves. We get heat energy from sun in this way.

Heat is usually transferred by infrared radiation.
The infrared heat is transferred to the food by radiation.
Its radiation
Although they do have some visible light, heat lamps skew towards the infrared end of the spectrum. Heat lamps are designed to emit light in the Near Infrared (.7µm-1.3µm), Middle Infrared (1.3µm-6µm), Far Infrared (6µm-40µm), and Far-Far Infrared (40µm-1000µm)

Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
Normal LED lamps produce almost no infrared light. However, just like there are LEDs in various colors like red and green, there are also infrared LEDs.
Heat, or Infrared energy.
A heat lamp emits infrared radiation, which is a type of electromagnetic wave. Infrared radiation has longer wavelengths than visible light, and it is often used to provide heat in various applications such as in heat lamps or infrared saunas.
