Cody Gakpo fired in the fourth before Liverpool briefly took their foot off the gas ahead of Sunday's trip to Manchester United in the FA Cup.
Veljko Birmancevic pulled a goal back for Sparta, but Dominik Szoboszlai and Gakpo completed the rout in the second half.
"It was an amazing win – and an amazing first 15 minutes," said Gakpo after an 11-2 aggregate victory.
"It's what we had in mind. It shows the confidence in the team at the moment."
Leverkusen boss Xabi Alonso has been heavily linked as Klopp's successor at Anfield, and his side remain unbeaten in all competitions this season thanks to Patrik Schick's stoppage-time double to beat Qarabag 3-2 on the night and 5-4 on aggregate.
Schick also struck in added time during the first leg as Leverkusen came from 2-0 down and they needed to do the same at home.
Abdellah Zoubir and Juninho gave the Azeri champions a stunning lead.

The Ghanaian ran from deep inside his own half through the heart of the Freiburg midfield and defence to slot in the fourth.
And Kudus then smashed home from the edge of the box.
"Obviously we've got two or three exceptional individual players who helped us get goals," said Moyes. "It was a brilliant performance for us to win by five."
