Nigel Pearson's men were without top goalscorer David Nugent for the visit of Blackburn Rovers, but the strike partnership of Chris Wood and Tottenham loanee Harry Kane still proved too strong for the visitors.
The Foxes started the night eager to put an end to a poor run of results that had seen them pick up just one point from their last three Championship matches.
And, Nigel Pearson can thank his 'keeper Kasper Schmeichel for ensuring his side had the best possible chance of winning the match after he pulled off what will certainly be a contender for save of the season midway through the first half.
City had been enjoying a prolonged spell of attacking play but their failure to convert a host of chances meant that Blackburn had an opportunity of their own to open the scoring when they won a corner on 23 minutes.
David Bentley's centre was cleared by Chris Wood, but when the ball was returned goalwards on the volley by Morten Gamst Pedersen, a goal looked inevitable, especially as the ball took wickid deflection just yards from goal. However, the Dane stopper displayed his incredible reaction speeds to claw the ball over the bar.
Minutes later, Leicester finally broke the deadlock. Ben Marshall, who has been lacking in form of late, found space out wide before producing an inch-perfect cross for Chris Wood to convert at the far post - his ninth goal in as many games for City.
Marshall was at the centre of the Foxes attacking endeavours once again when the home side doubled their lead minutes before the break.
The winger sent in another a superb cross, this time Harry Kane duly obliged to nod home – capping another impressive performance for the youngster who joined on loan from Tottenham last week.
The Foxes lead never looked in doubt in the second half and the three points were all but won before Andy King ended his goalless run with a headed finish from a Martyn Waghorn corner deep into stoppage time.
This impressive win sees the Foxes close the gap to second-placed Watford. And, a game in hand over their rivals combined with the fact that now just five points separate Nigel Pearson’s team and an automatic promotion spot gives the Foxes faithful something to finally shout about after ending a poor month on a high note.
