Le Fondre was introduced when Wolves were 2-1 down against Ipswich, and he showed the quality that he possesses by putting in an excellent display.
The Cardiff City loanee set up Benik Afobe’s equaliser, and was a constant menace during his time on the pitch.
And Jackett said: "Adam Le Fondre did really well when he came on, both his assist for the second equaliser and his overall attitude. When we went to two up front, the game opened up and we had chances to win the game on the break.
Jackett admitted to the Express and Star last week that Le Fondre has been unlucky at Wolves so far.
The 28-year-old has not has as many starting opportunities as he would have been hoping for after arriving at Molineux to date.
However, Le Fondre will hoping that his display against Leicester can force him back into first-team contention in the coming weeks.
Wolves’ next match comes against Milton Keynes Dons at the weekend, where they will be hoping to pick up their first win in four matches.
