Crouch was handed only his third start of the season at Deepdale but responded with three goals on the night.
Redknapp must now decide whether to stick with the England striker alongside Jermain Defoe against Burnley on Saturday or recall the rested Robbie Keane.
"It was a good hat-trick from Crouchie and good to see Robbie and Jermain get one each as well," said Redknapp.
"(Roman) Pavlyuchenko was injured, otherwise he might have scored and made it even harder for me. But it's a nice problem to have.
"We've moved on a lot in the last year and I thought we looked sharp and that every time we went forward we could open them up."
Meanwhile, Redknapp was also pleased to see defender Michael Dawson come through his first game of the season unscathed.
He added: "It was good to get Michael Dawson back playing again.
"He's been out for a long time with his Achilles injury and a few weeks back we wondered when he was ever going to play."
