It was far from an easy victory for the home side though and they had to work hard during a bad-tempered game during which five Blackburn players were booked.
The visitors actually started the game well and almost took the lead through Nikola Kalinic, but the striker's curling shot went inches wide of the post.
They were then made to pay for not taking this chance as Liverpool took the lead on 20 minutes. Yossi Benayoun's square pass across goal was easily converted by Gerrard from six yards out.
The home side then looked to increase the tempo of the game, but Blackburn were not lying down to be defeated and managed to win themselves a penalty when Morten Gamst Pedersen's shot was blocked by the hand of Jamie Carragher. Keith Andrews then squeezed the penalty under Jose Manuel Reina to level things up.
It wasn't long before Liverpool were ahead again though as an unmarked Torres slid home from close range after 44 minutes.
The second half wasn't packed with as many incidents as the first, but there was plenty of challenges flying in from both teams and things became heated on more than one occasion.
Blackburn's best chance to equalise came in injury-time when Christopher Samba's header from close range deflected of Dirk Kuyt before being superbly saved by Reina. The home side then held on for the remaining couple of minutes to secure their first Premier League win in three games.
