In the build-up to the match Palace manager Alan Pardew spoke of his admiration for Vardy, who like himself reached the top flight relatively late in his career after progressing through non-league football.
By his recent standards it was a relatively quiet afternoon for the busy striker but there was much to admire about the finish from Vardy that won the contest
However, Pardew would have found little to like about his team's defending which presented him with the chance to score his 10th goal of the season
In reaching double figures, Vardy found the back of the net for the seventh successive Barclays Premier League fixture, adding his name to an elite group which includes Ruud van Nistelrooy, Daniel Sturridge, Mark Stein, Ian Wright, Alan Shearer, Thierry Henry and Emmanuel Adebayor
While manager Claudio Ranieri will be delighted for his fifth-placed side, a first clean sheet of the season - at the 12th time of asking - will please the Italian most
Given the attacking talent on display in both teams, the first half was surprisingly low on action
Leicester went close after seven minutes
Marc Albrighton cut inside from wide on the right and hit a shot with his left foot
It was a tame effort but the way Wayne Hennessey casually left it had you believe it was well off target - it was not
The ball struck the inside of a post, much to the goalkeeper's relief, and Riyad Mahrez put the rebound wide as Jeffrey Schlupp lurked at the far post
Palace threatened for the first time in the 19th minute as Robert Huth made a vital i nterception to prevent Bakary Sako from laying on a tap in for Fraizer Campbell inside the six-yard box
Another timely tackle from N'Golo Kante shortly before half-time snuffed out a dangerous-looking counter-attack from Palace which was led by Campbell
Vardy struck the decisive blow in the 59th minute
After a loose defensive header, Brede Hangeland then mis-hit a clearance straight to Mahrez, who sent Vardy racing through on goal for a lovely lofted finish over Hennessey
The England striker had to make sure the ball reached the net, blasting it home from inside the six-yard box
Kasper Schmeichel preserved Leicester's lead with a superb reaction save with 12 minutes remaining to keep out a header from substitute Patrick Bamford
Home hearts were in their mouths in the final minute when another Palace sub Wilfried Zaha went down inside the penalty area but referee Mike Dean booked the winger for diving
Leicester had to survive some late Palace pressure but a first clean sheet of the campaign in the week he celebrated his 64th birthday was a welcome present for Ranieri
