It was an easy triumph in the end for Fulham, with Norwich left wondering where their next win is coming from as they have now gone eight games without a victory.
Late chance for Norwich as Snodgrass' ball in is half-cleared, before Johnson's lashed follow up goes high and wide.
Kasami is caught in two minds on the edge of the area, with his eventual ball neither a cross or a shot.
Nice run from Kacaniklic as he jinks his way into the box and fires in a shot looking to make it 4-0, but Bunn makes the save.
Kasami gets back to stop Murphy in his tracks, with the youngster having been much quieter this half.
Dejagah nips into the box and whips over a cross which is too hard and high for Dembele to get onto.
Becchio is penalised for putting too much pressure on Karagounis as he clears from inside his own box.
Kasami has some space in the Norwich half, but his attempted ball towards Bent is cut out by Bassong.
Nice ball from Johnson out towards Garrido on the left flank, but his ball back into the box is behind the three yellow shirts who are in there.
Another decent spell of possession for Norwich, but they are really struggling to break down the Fulham defence.
Great block from Burn, heading away from inside his own six-yard box after van Wolfswinkel's powerful strike at the back post.
Bent feeds Kacaniklic, but the return pass towards the striker takes a flick off a defender and the chance is gone.
Moments before Sidwell struck, Garrido had to produce an excellent defensive header on his own line as Dejagah looked to convert Kacaniklic's cross. Norwich failed to clear their lines, though, and now look out of this contest.
Simple, simple goal for Fulham. Riether's deep cross from the right flank is headed home from six yards out by Sidwell. Looks like game over here.
Couple of party pieces from Dejagah as he shows neat control and some outrageous skill to bamboozle two Norwich defenders, before playing the ball back towards his own half.
Now Richardson swings a hanging ball into the Norwich box, with Bunn gathering ahead of Hangeland. Good piece of alert goalkeeping.
Snodgrass whips the ball into the area and the back-pedalling Bassong is just able to divert his header towards goal, but without any real power Stekelenburg claims comfortably.
The ball is played back to Whittaker to swing a cross in, but he gets hopelessly under the ball and lofts it high over Stekelenburg's bar.
Mason stops the game with Elamander down after a challenge from Hangeland, with the Norwich forward getting gingerly to his feet.
Karagounis attempts a ball over the top to Dejagah, but puts too much on the pass, which skips off the now greasy surface and through to Bunn.
And another good challenge from Johnson on the edge of his own box as he stops Kasami from bursting into the area.
Good play by Dejagah as he looks to trick his way past three defenders out on the right, but Johnson is in the right place to clear.
Elmander and Whittaker attempt to combine to find a way intot he box, but the return pass from the latter is too strong and Hangeland is able to clear.
Nice play from Fulham, with Kasami finding Kacaniklic, who cuts it back to Sidwell, with Bunn off his line quickly to gather the floated cross towards the back post.
Hopeful ball forward towards Bent gives the striker something to chase, but Martin tidies up with the minimum of fuss.
Fulham are really on the back foot in the early stages of this first half, with some poor passing not aiding their cause and inviting more pressure.
Norwich keep up the pressure and Snodgrass gets to the touchline and fires over a low cross, which Stekelenburg saves with his feet, before Mason spots an infringement in the resulting scramble.
Half-hearted penalty appeals are waved away before Johnson breaks forward and van Wolfswinkel fires in a snap-shot which Hangeland blocks away for a corner.
The arrival of van Wolfswinkel should pose a new threat to Hangeland and Burn, who were relatively comfortable in the first period up against the lone threat of Elmander.
Hughton has made one change at the interval, with Ricky van Wolfswinkel on in place of Redmond to offer more support up front for Elmander.
Referee Mason brings the half to a close. Goals from Bent and Dejagah have Fulham in control, with Norwich's best chances coming after just three minutes, when Snodgrass hit the bar.
Snodgrass' inswinging corner is met by the head of Johnson on the edge of the six yard box, but he gets under the ball and his header goes over the top.
Snodgrass swings a cross in which takes a nick off a defender and Riether is back to clear for a corner.
Norwich boss Hughton has some thinking to do over the interval, with his side having offered little in attack after their two chances in the opening three minutes.
Fulham double their lead as Riether plays in Kacaniklic on the right of the box with a neat pass, he cuts it back into the path of Dejagah who has the simple task of converting from close range.
The ball is flighted in towards Bassong, but Hangeland heads away before Karagouis completes the clearance.
Hangeland takes a risk as he turns in his own half under pressure from Snodgrass, but the Norwich man is penalised for a foul.
A wayward pass after some decent Fulham possession gifts the ball to Norwich, before Burn has to be alert to deal with the threat of Elmander out to the left of the Cottagers box.
Sloppy play from Fox as his square pass is cut out by Kacaniklic, who advances towards goal and fires in a low shot which is easy for Bunn to claim.
Snodgrass is holding his jaw and looks in a bit of pain after being caught by a wayward arm from Sidwell as they battled for the ball.
Sidwell steals possession in the central third, with Kacaniklic then feeding Bent, but his attempted cut back is intercepted by Martin, who seems OK after his earlier problem.
Murphy and Redmond have switched flanks once again, with the exuberant youngster attempting to get away from Kasami near the corner flag, but just over-running the ball.
Kacaniklic and Richardson combine well down the left flank, but the latter's cross after a good overlapping run flies out for a goalkick.
Dejagah';s corner comes to nothing. Martin is still hobbling, but looks keen to try and run this knock off, after taking an accidental boot to his knee from Kacaniklic.
Another Fulham attack follows, with a deep ball towards Bent at the far post smuggled away for a corner. Martin is limping at present but the game goes on.
Riether steps out of defence and tries his luck from distance only to see his low shot fly across the face of Bunn's goal and wide.
Great determination from Kacaniklic as he twists and turns his way into the Norwich box before eventually being crowded out.
Fulham are content to knock the ball around in defence, before pressing forward and probing for another opening.
Bassong is penalised for wrestling Kasami to the floor inside the Norwich half, but Fulham's free-kick comes to nothing.
Hangeland attempts to flight a ball over the top of the Norwich defence to Bent, but Bunn is able to gather.
Goal out of nothing for the home side, as Kasami is released down the right, with his cut-back not dealt with by Garrido, allowing Bent to fire home a first time shot from 10 yards out.
Kasami curls in shot which goes around the wall and bounces just in front of Bunn but the keeper claims with relative ease.
Garrido brings down Dejagah in a dangerous position outside the Norwich box. Good chance for Fulham to test Bunn here with the ball some 25 yards out and slightly to the right.
More skill from Murphy, who is now on the right, stepping away from Richardson with ease before firing over a low cross towards Elmander which Burn clears.
Redmond has switched over to the left and he advances into the space offered him by the Fulham defence before firing in a low shot from outside the box which he drags wide of Stekelenburg's near post.
First real chance for Fulham as Dejagah feeds Sidwell, who steps away from one challenge before firing in a powerful drive which thuds into Bunn's midriff.
Hangeland is caught napping and is robbed by Elmander out to the right of the area. The Norwich man cuts the ball back but Karagounis is there with a key interception.
Bassong dwells on the ball in his own half and Kasami snaps into the tackle, but the Fulham man gets a bit over-heated and gives away a free-kick.
Elmander gets in another shot on goal after teeing himself up with a neat touch, but the finish lacks any real power and Stekelenburg gathers with ease.
Fulham have kept their cool despite being pushed back early on, with Meulensteen's men keen to play the ball out from the back.
Impressive start from Norwich, close to taking the lead twice already, with teenager Josh Murphy making an instant impact.
OFF THE BAR!!! Norwich keep the pressure on and Snodgrass cuts inside and unleashes a curling shot which beats Stekelenburg all ends up before crashing back into play off the crossbar.
GOOD SAVE!!! Excellent run from Murphy as he dances across the face of the box before feeding Redmond, who brings a low save from Stekelenburg.
Sidwell floats a diagonal ball forward towards Dejagah but the forward fails to bring it under control and raises a hand in apology.
The two teams are in what passes for a tunnel at Craven Cottage - the space between two stands - and kick-off is now just minutes away.
The two teams also met in the Premier League at Carrow Road on Boxing Day, with Fulham winning 2-1 on that occasion - Scott Parker scoring the winner three minutes from time.
James Bird has been in touch via Twitter and says: 'I'm going for a 2-1 win for Norwich with Murphy to score first.'
Don't forget that if the two teams cannot be separated over 90 minutes tonight, then we will have extra time and penalties to decide the winner.

Norwich boss Hughton has made six changes to his team, with 18-year-old twins Josh and Jacob Murphy both named in the squad, with the former in the starting XI.
Fulham are boosted by the return from injury of goalkeeper Maarten Stekelenburg and defender Brede Hangeland, with the experienced centre-back partnered by former Darlington player Dan Burn. Scott Parker and Dimitar Berbatov are not involved this evening.
Given their struggles in the Premier League, it's no surprise to see both Rene Meulensteen and Chris Hughton make changes to their teams tonight.
Fulham: Stekelenburg; Riether, Hangeland, Burn, Richardson; Karagounis, Sidwell; Dejagah, Kasami, Kacaniklic; Bent. Subs: Stockdale, Hughes, Rodallega, Dempsey, Christensen, Tankovic, Dembele.
Norwich: Bunn; Whittaker, Martin, Bassong, Garrido; Fox, Johnson, Snodgrass; Redmond, Josh Murphy, Elmander. Subs: Ruddy, Van Wolfswinkel, Fer, Hoolahan, Becchio, Ryan Bennett, Jacob Murphy.
The team news for tonight's clash will be announced shortly, and we will bring it to you as soon as we have it.
Both teams go into the match struggling at the wrong end of the Premier League table and on the back of weekend defeats. Fulham suffered a damaging 4-1 defeat at home to fellow strugglers Sunderland, while Norwich were beaten 2-0 at Everton.
The incentive for the winners is a fourth round trip to Sheffield United, with the Blades having already claimed one Premier League scalp in the shape of Aston Villa.
The first meeting between the two teams at Carrow Road back on January 4 ended in a 1-1 draw with Darren Bent and Robert Snodgrass the men on target.
