Ameobi hit his 15th goal in European competition to send the Toon into the next round.
Pardew said: "I had a little quiet word with Shola before the game because, in the last few weeks, I thought his contribution could have been greater.
"But he's shown tonight what quality he has. Against this team, I always thought he might influence the game. He did that all night really and it bodes well moving forward."
