James Maddison and Harvey Barnes scored their first European goals as Leicester marked their return to continental action with a comfortable home win.
The Foxes had looked set to secure Champions League football for the majority of last season but set about their task in the second-tier competition with zest after a sticky start.
Ukrainian visitors Zorya had their moments in the opening stages and Kasper Schmeichel was called into serious action with the score at 0-0.
But even without the injured Jamie Vardy, Brendan Rodgers' side ultimately had too much.
Barnes, the standout performer on the night, curled a shot against the post and when Kelechi Iheanacho flicked the loose ball out, Maddison had a simple finish.
Barnes then ran through the heart of the Zorya defence to clip in a second and Iheanacho took advantage of a defensive lapse to score the third.
Foxes boss Brendan Rodgers later said, "It was a very good win, it's nice to get the points on the board and a clean sheet. We had to work hard, there's areas where we can get better.
"They play a diamond and it's a system where they can hurt you on the inside. When they had the ball they were a threat but we killed the game in the second half.
"The players deserve a huge amount of credit. They can be better, we need more movement at the top end of the pitch because we could have got in more."
