Liverpool settled the issue with three goals in 13 ruthless first-half minutes, with an electric Luis Suarez bagging two and Daniel Agger the other.
"I wouldn't say it was easy, that would be disrespectful to QPR, they are having a tough time," Gerrard told Sky Sports.
"If we started well we knew we could quieten the crowd and that was the best we've played this season in the first half.
"The plan was for us to get more goals, but Harry Redknapp is a top manager and QPR changed things in the second half so credit to them."
As to Suarez, Gerrard added: "He's been brilliant ever since he came here. He's a magician.
"These clubs have to play him twice a season but we have to play against him every day!"
