The Frenchman was dominant throughout the event and came into the final day's stages with a 46.6-second advantage over nearest challenger Mikko Hirvonen (Citroen).
Any doubts over the outcome of the race evaporated when Hirvonen rolled his car at a hairpin and was forced to retire.
That left Ogier to cruise home 76 seconds clear of second-placed Thierry Neuville, who enjoyed the best finish of his career at the wheel of his Ford Fiesta.
Ogier's Volkswagen team-mate Jari-Matti Latvala, the victim of an early puncture on the opening day, recovered well to take third place.
"We managed the rally perfectly all the time," said Ogier, who now leads the drivers' standings by 64 points from Latvala.
"We pushed when we needed to and were more careful when it was rough and more dangerous for the tyres. In the end it was a perfect win."
Belgian driver Neuville, meanwhile, is up to an unaccustomed third place in the championship standings after a second consecutive podium.
Such was his advantage over Latvala towards the end of the rally, Neuville even had time to take a detour on the day's final stage after a run-in with a local.
"We met a cow in the stage and had to slow down and turn around," he calmly explained.
Dani Sordo claimed fourth for Citroen ahead of Martin Proko, while Welshman Elfyn Evans impressed as he took sixth place on his debut in a WRC car.
Ex-Formula One driver Robert Kubica came home ninth overall as winner of the WRC 2 class.
