After suffering a 2-0 defeat to leaders Liverpool on Sunday, a pumped-up Pep Guardiola made four changes to his starting lineup, with captain Kevin De Bruyne notably handed his first start since September 18 at the expense of Phil Foden, who missed out due to a bout of bronchitis.
De Bruyne's playmaker abilities - which City have dearly missed during their poor run of form - were on full display at the Etihad Stadium, and although the Belgian is known to have a wand of a right foot, it was his downward header towards goal that fell nicely for Bernardo Silva to tap home an eighth-minute opener on the line.
Man City were playing with confidence and came close to adding a second on several occasions; Josko Gvardiol would have netted a brace on another day but he headed one chance narrowly wide before dragged another beyond the far post after bursting through on goal.
Forest were unable to put their stamp on the contest, but they came close to equalising twice midway through the first half. Stefan Ortega made a superb diving save to keep out a strike from Morgan Gibbs-White, before Chris Wood surprisingly rolled a shot wide after running through on goal.
That chance from Forest's top scorer proved costly, as De Bruyne went up the other end just over a minute later to double City's advantage with a right-footed shot fired into the top corner from inside the area.
Forest switched to a back three in the second half and there was much more about Nuno Espirito Santo's side in the opening exchanges. However, they were caught on the break just before the hour mark when Jeremy Doku jinked his way inside from the left before curling a sweet strike into the bottom corner to put City three goals to the good.
Man City threw away a three-goal lead with less than 15 minutes remaining against Feyenoord in the Champions League just over a week ago, but they saw out the game against Forest with ease as Nuno's men had no answer to the Citizens' rearguard resolve.
Victory for Man City represents their first since beating Southampton 1-0 on October 26, and they have climbed up one place to fourth in the Premier League table - also moving to within nine points of leaders Liverpool who drew 3-3 at Newcastle United.
As for Forest, they have now lost their last five away league games against Man City by an aggregate score of 15-0, and they have slipped to seventh in the top-flight standings, now sitting four points behind the top four.

MAN OF THE MATCH - KEVIN DE BRUYNE
Kevin De Bruyne had to patiently wait for a return to Man City's starting lineup following his recovery from a niggling injury, but the playmaker excelled in the final third for Guardiola's side against Forest, setting up the opener before scoring a superb second midway through the first half.
The hugely influential 33-year-old, who also completed a match-high four key passes, came off to a standing ovation from the Etihad faithful on the 74-minute mark, and deservedly so.
