Manager Scott Parker praised forward Ivan Cavaleiro's "courage" as his penalty helped Fulham climb out of the Premier League relegation places.
Parker's side had missed three penalties in a row before Cavaleiro converted to help secure victory at Leicester, who missed the chance to go level on points with leaders Tottenham.
The Portuguese had been one of the spot-kick culprits - missing in a 3-2 home defeat by Everton eight days earlier - and Parker was impressed with the way he stepped up.
Aleksandar Mitrovic had hit the bar with a penalty at Sheffield United in October, and Ademola Lookman had been widely criticised for a failed attempt at a Panenka-style spot-kick in the defeat by West Ham on 7 November.
