Goals from Nani, Simao Sabrosa, Miguel Veloso and Edinho made it a comfortable evening for Carlos Queiroz's side in Guimaraes.
Manchester United midfielder Nani calmed any Portuguese nerves by scoring after 13 minutes. Veloso played the ball in from the left and Nani, just outside the 18-yard box, was quick to get his left-footed shot away to find the bottom corner.
The second goal arrived a minute before half-time when Simao rammed home another shot from outside the penalty area.
Portugal's third goal was a crisp finish from Veloso from around 12 yards, after Liedson could not convert Nani's pass, while Edinho converted a pass from Simao for the fourth.
The Portuguese have recovered well after a dismal first half of their bid to reach South Africa, and will fancy their chances of reaching the finals, given they will be among the seeded teams in next Monday's draw
