Romelu Lukaku scored twice for Everton in a 4-2 victory on Sunday as Craig Shakespeare suffered defeat for the first time since becoming Leicester City manager.
Shakespeare had won all of his first six matches in charge, five of them in the Premier League, since replacing the sacked Claudio Ranieri in February.
Tom Davies poked in for the hosts after 30 seconds, before Leicester rallied with a slick counter-attacking goal from Islam Slimani and a superb free-kick from Marc Albrighton.
But Leicester, much changed before Wednesday’s Champions League quarter-final at Atletico Madrid, never looked comfortable.
Lukaku headed in a Ross Barkley cross to draw Everton level and Phil Jagielka was allowed too much space at a corner as the Toffees reached the break ahead.
Lukaku drilled in from close range after the interval and the withdrawal of the bright Demarai Gray and striker Jamie Vardy seemed to signal Leicester’s attentions turning towards Europe.
