The Prema driver held the lead off the line and despite briefly dropping behind Theo Pourchaire on lap three, recaptured the front spot on the following tour.
From there, it was a straightforward cruise to victory for the Ferrari Academy driver to take his second win of the weekend.
Enzo Fittipaldi finished second for his first podium with Rodin Carlin, having passed Pourchaire just five laps from the end around the outside of Turn 3, with the ART driver completing the rostrum and taking the championship lead.
An uncharacteristically sedate feature race saw the order remain much the same around the first lap, with the only big mover Victor Martins, climbing to fifth having lined up eighth for ART.
Pourchaire, who started third, took second from Fittipaldi the following lap on the run down to Turn 3 with the help of DRS, before capturing the lead from Bearman down to Turn 1 at the beginning of lap three.
It wasn’t to last though, as Bearman regained the lead the following time round by replicating Pourchaire’s move.
He quickly built a gap over one second to the Frenchman before pitstops began on lap six, with team-mate Frederik Vesti the first to stop.
The leading pair pitted on lap eight, with Bearman retaining the advantage ahead of Pourchaire and Fittipaldi.
