Defender Jurrien Timber sent them on their way in the 64th minute after he collected a pass from Noni Madueke and lifted a clever finish over Berke Ozer.
England forward Eberechi Eze added the second three minutes later when he finished first time from substitute Bukayo Saka's cross.
Having won at Napoli, Arsenal sealed a second victory in the competition when Saka himself rolled in the third in the 71st minute - six minutes after coming on.
The result moved last season's beaten finalists up to third place in the fledgling Champions League table.

In normal circumstances of course he should keep this behind close doors. But this is not normal times. The squad has had enough of the owners' lack of ambition. I fully support his comments. He's passionate about the club.

As you can imagine, those comments from Lisandro Martinez have caused a storm.
Wayne Rooney said "something like that would rip the dressing room apart", while his former Manchester United team-mate Ashley Young felt Martinez "did not have the right" to make the comments and ex-Liverpool defender Jamie Carragher described them as "awful".

'I expect more...I expect more from our technical director'published at 08:21 BST
Atletico Madrid 2-0 Man Utd
Image source, Getty ImagesManchester United made it five games without a win with a 2-0 defeat at Atletico Madrid in the Champions League on Tuesday night.
But this morning's hot talking point centres on explosive comments from the club's Argentina defender Lisandro Martinez, who criticised the lack of investment in the team over the summer.
"We did a fantastic season last season and now we expect more from the top, more players to compete because many teams bring many players as well," he told broadcaster Amazon Prime.
"Atletico have an amazing team and they deserved to win today.
"I expect more [investment]. 100%. I expect more from our technical director [Jason Wilcox].
"I have to be honest, as players we have to do more but it is also important when you make a strong squad to be ready for this kind of night.
"Tonight it is easy to [blame] the coach, easy to say the players but also we have to see other areas."
