Pierre-Emerick Aubameyang bagged Arsenal's second goal when he converted the rebound after his penalty was saved.
Emile Smith Rowe put the result beyond doubt early in the second half as Arsenal climbed to ninth place in the Premier League.
After losing their first three league games, Arsenal have gradually recovered their equilibrium.
Successive draws against Brighton and Crystal Palace had brought renewed pressure on Arsenal boss Mikel Arteta, but this was a tantalising glimpse of what they could be under the Spaniard.
They won't find many opponents as obliging as Villa, who still looked shell-shocked after conceding three goals in the final 10 minutes to lose 3-2 against Wolves last weekend.
Jacob Ramsey's late goal was no consolation for a Villa team on a run of three consecutive defeats.
Villa striker Ollie Watkins was fortunate to stay on the pitch after kicking out at Gabriel in the first minute.
That was the only show of defiance from Villa as they were blown away by Arsenal's sustained assault.
Aubameyang's audacious overhead kick ran across goal to Bukayo Saka and the winger fired over from a tight angle.
Making his first Premier League start, Arsenal defender Nuno Tavares blasted over from a good position after scything through the Villa defence.
Partey stabbed against the crossbar after Villa failed to clear Saka's free-kick.
Arsenal's relentless pressure finally paid dividends in the 23rd minute.
Thomas Partey scored from a header to set Arsenal on course for victory
Partey rose above the flat-footed John McGinn to meet Smith Rowe's corner with a flicked header that just evaded Emiliano Martinez's despairing dive.
Tavares was finding space down the left every time he went forward and his low cross reached Saka, who should have scored but shot straight at Martinez.
Arsenal were rampant and increased their lead on the stroke of half-time.
Matt Targett's challenge on Alexandre Lacazette was initially ignored by referee Craig Pawson, but after being urged to consult the pitchside monitor, he changed his decision and awarded a penalty.
Villa boss Dean Smith was incensed, although replays showed Targett caught Lacazette just before touching the ball.
Aubameyang's spot-kick was saved by former Arsenal keeper Martinez, but the Gabon forward was first to the rebound and slotted in his seventh goal this season.
Unable to muster a single shot in the first half, Villa finally tested Arsenal keeper Aaron Ramsdale through Watkins' strike soon after the interval.
It was a false dawn as Arsenal quickly resumed their dominance.
Villa considered a move for Arsenal's Smith Rowe when they chased a replacement for Jack Grealish in the close-season.

They were unable to land the young midfielder and he showed what they missed out on with the latest in a growing list of influential displays.
Sprinting onto Aubameyang's long pass, Smith Rowe drilled a fierce strike that deflected off Tyrone Mings and then the post on its past Martinez in the 56th minute.
Ramsey curled home from the edge of the area with eight minutes left, but the quality of the finish was at odds with the rest of Villa's lacklustre display.
