It was a League Cup match against Fulham at Craven Cottage, however, the return leg at Anfield saw him score all five in a 5-0 walloping.
"Funnily enough, a lot of people think the [5-0 win] was my debut," he explained to Sport magazine in 2013.
"For a young lad to score one goal is massive in my eyes, because it's the Liverpool first team. But then I got two, three, four and five and I think I became the fifth Liverpool player in the club's history to have done that."
And while the Kop were delighted to have been introduced to such an exciting talent - they would eventually nickname him 'God' - the 18-year-old was given a sharp reminder of the work needed to get to the top as soon as the game was over.
"I remember going into the dressing room after the game and I was absolutely over the moon to have scored five," Fowler explained.
"I could think of every football cliche under the sun to describe it, but [Liverpool coach] Ronnie Moran turned around to me and said I should have had six. That was just typical of Ronnie and the staff at Liverpool."
It's a fortnight Fowler has never forgotten and never likely to forget even if his actual debut is a bit of a blur.
His dad had travelled down to London to watch the game, so was there to see his son smash Don Hutchison's cross past Jim Stannard in a 3-1 win in front of the other travelling supporters.
"From then on I went from strength to strength, and managed to score a few goals," he added modestly.
