The 27-year-old France international was left out of the starting line-up for Monday night's Barclays Premier League trip to Everton with his manager feeling something had not been quite right with him in training.
However, with his side trailing 3-0 at half-time and in danger of succumbing to a humiliating defeat, Pardew threw Cabaye on and watched him orchestrate a fightback which came up just short as they lost 3-2.
The Frenchman is likely to be restored at Cardiff on Saturday, when his manager will hope for more of the same, although he admits an over-reliance on a man who was coveted by Arsenal during the summer would be a dangerous thing.
Asked if Cabaye's display at Everton illustrated why it was so important for Newcastle to retain his services, Pardew said: "Yes, but we mustn't rely on him.
"His forward passing, his forward thinking got us back into the game, but there will be times when he is not there and we need to have that same attitude.
"But the answer to your question is he is very important. He's a great player and this club needs great players.
"He is one of the players who gives us the consistency of performance every week, and that's what some of our guys are searching for."
Newcastle head for South Wales needing a victory to rekindle their season after successive league defeats by Hull and the Toffees, and in the circumstances, Cabaye's name on the teamsheet would come as a welcome boost.
Pardew said: "He has trained this week since the game with no problems, and I don't see any issue with him in terms of starting this particular game."
