The 32-year-old defender played the full 90 minutes as an overage player in the youngsters' victory over Blackburn on Monday and he is targeting further run-outs at that level as he tries to get himself up to full fitness.
Last season was almost completely ruined by a calf injury for Hibbert - he made just six appearances - and this season hasn't started much better for the player who is struggling to get himself up to speed.
"It was my first 90 minutes for a while and I needed it. It was a good game to play in," Hibbert told the Everton website.
"Possibly [I need to play more Under-21 games]. I need a lot more hard training sessions as well to get my breathing and fitness up there.
"It's up to the manager if he wants me to play in any more reserve games. It's good to get out there and play."
