But this term he has slipped down the pecking order at the King Power Stadium with Jamie Vardy, Shinji Okazaki and Leonardo Ulloa all ahead of him in the mind of Claudio Ranieri.
Kramaric however left the club in January, joining German side Hoffenheim on loan.
It must have been a simple decision right? Wrong.
"It was not easy to go from Leicester, it was one of the most difficult decisions of my career, and heavier than when I left Dinamo (Zagreb).
"You're looking at a team that is fighting for the English champions title, but you're not on the scene, they told you to your face that you will not get an opportunity.
"Simply, you have to break the sentiment, cross your dream and move to where they will take into consideration, where you are needed.
"I knew in England I would not get to play, so in search of minutes I went to the Bundesliga."
Kramaric however had to think about his international career. Croatia have qualified for the European Championships in France next summer and without first-team football he would have had no chance of making it into the team.
Now he must hope to impress in Germany and earn himself a spot back in the Croatian fold.
