Dyche replaced the sacked Ange Postecoglou on Tuesday, to become the club’s third manager this campaign, and led Forest to their first win since the opening day of the season, along with their first clean sheet since April.
Morgan Gibbs-White made no mistake from the spot in the 19th minute after a Jan Bednarek handball and Igor Jesus did likewise 13 minutes from time to calm the nerves of the home fans, finally able to celebrate for the first time since August.
Forest have four points, having drawn at Real Betis and lost at home to Midtjylland, while Porto’s unbeaten run in all competitions this season comes to an end and they remain on six points.
