Burnley overwhelmed Blackburn Rovers with three second-half goals as Vincent Kompany's Clarets returned to the top of the Championship in style.
In the first league meeting between the two old East Lancashire rivals in six-and-a-half years, it was goalless at half-time as the hosts took until just before the break to test visiting keeper Thomas Kaminski.
But Barnes broke the deadlock on 55 minutes, timing his run to meet Zaroury's left-wing cross and power a header into the bottom right corner.
They then doubled their lead on 74 minutes when Barnes' right-foot volley on the turn was well saved by Kaminski, the ball ran loose and Zaroury drilled in a low right-foot shot from the edge of the box - for his sixth goal of the season.
And Barnes, who had also scored in the 3-1 midweek Carabao Cup win over Crawley, wrapped up the scoring nine minutes from time.
