The Hungarian stopper, 25, made a string of fine saves on his way to keeping his first clean sheet since August.
"It was a great game of football with great moments of attacking play and even better defending," said Freedman.
"The defence has been something that hasn't being great here previously and over the time I've been here it seems to have improved dramatically.
"I didn't think that Leicester deserved to win the game but they did create plenty of chances. Luckily for us though Adam showed how good of a young goalkeeper he is to get a clean sheet for us."
Bolton have claimed four points from a possible six since Freedman took charge at the Reebok Stadium last month.
They currently sit 17th in the Championship table, 11 points behind league leaders Crystal Palace.
