The hosts had it all to do after a disappointing 1-0 defeat to FC Noah away in Armenia, where AZ Alkmaar showed little ambition to book a spot in the round of 16.
AZ got off to the necessary hot start via Ro-Zangelo Daal after the young forward volleyed the ball into Aleksey Ploshchadnyi's net in the fifth minute.
With the score level over two games, AZ controlled the majority of the first half and allowed Noah very few chances.
In the 38th minute, Sven Mijnans scored his fourth goal of the UEFA Conference League campaign with the first shot of the game in 16 minutes, finishing a smart free-kick from Peer Koopmeiners in the bottom corner.
Without creating a single chance in the first half, Noah's lack of offensive firepower continued in the second half, which AZ controlled with ease and started by scoring the 3-0 through Mijnans, who tapped the ball in an empty net.
With the chance to score the easiest hat-trick of his life, Sven Mijnans squandered a chance to put the ball in an empty net by missing a smart cross from Kees Smit and getting it on his thigh instead.
The hosts played out the game professionally and didn't give up a chance against Noah, while adding one last goal to their successful home outing in the 91st minute - Ireland hero Troy Parrott saw his effort get saved by Ploshchadnyi, but the Russian stopper stood no chance against Isak Jensen's rebound.
It was a sour night for FC Noah, who ended their maiden European knockout stages with a 4-0 loss in Alkmaar. Meanwhile, AZ will get to know who they'll face in the round of 16 during Friday's UEFA Conference League draw.
