Pardew will hope Benteke's contribution is the first of many as he attempts to establish himself once again at Selhurst Park.
He said: "It's very important for a striker to get that first goal, and as soon as the cross came in, you kind of knew. I don't think any defender could defend him in that position when he's coming on the back of you like that.
"He's a bit like Andy Carroll. If the ball is in the right area, it's almost impossible to defend."
Pardew also gave Benteke's brother Jonathan a debut late on.
