Arsenal beat Newcastle 4-1 at the Emirates Stadium and Pardew was forced to start the 21-year-old due to injuries to both Tim Krul and Rob Elliot.
As the 53-year-old admits, Alnwick's Premier League debut for Newcastle could have gone better.
However, the Magpies boss did defend the young shot stopper's overall display at Arsenal, as he was encouraged by certain aspects of his game.
"I can probably look at one goal as Jak maybe at fault," Pardew is quoted as saying by the Shields Gazette.
“The second, he might have wanted to stay in his goal a bit longer without coming out. Other than that, I thought he was pretty sound.
"A few times it flashed across and he got little touches. He kicked it well, looked assured. I can’t lay any blame at his door for this result and he goes to the next game.”
