The 21-year-old says that he is already looking ahead to the trip to Brighton & Hove Albion in the fourth round.
"I don't know if I'll ever hit another one like that in my life, and it was a great set-up from Olivier [Giroud]," Wilshere told ESPN.
"It was important we got the win in 90 minutes, we'd created chances (before the goal) but we just couldn't put it in.
"We know what the FA Cup means in England. It's a great competition and we wanted to be in the next round, but we've got a tough game away to Brighton."
Arsenal travel to Chelsea in their next game on Sunday.
