In this work, starting from a spherically symmetric polytropic black hole, arotating solution is obtained by following the Newman--Janis algorithm withoutcomplexification. Besides studying the horizon, the static conditions andcausality issues of the rotating solution, we obtain and discuss the shape ofits shadow. Some other physical features as the Hawking temperature andemission rate of the rotating polytropic black hole solution are alsodiscussed.
