The Ibrox summer signing was in excellent form for Rangers against his old side.
Stewart netted his first ever Gers goal during a 5-0 rout that pushed Steven Gerrard's side closer to league leaders Celtic.
Also assisting on the afternoon, it was a real statement performance from the former Dons man.
However, he feels he could have scored even more and really piled the misery on the Pittodrie outfit.
As quoted by The Scottish Sun, he said: "Am I disappointed to just score one? I am a wee bit.
"I could have had three or four but I didn’t want to be too greedy! However, I’m a little disappointed I didn’t take more chances.
"Was it sweeter to score against Aberdeen? You don’t really think like that. You go out and do your job. It was good just to get a game, actually. It’s been a while."
What next for Stewart?
Saturday's display felt like a breakthrough moment for the summer signing. That the Rangers manager trusted him to start a match of such importance to the club is a real sign he is becoming a more important of Gerrard's plans.
Gerrard also has a track record of rewarding good performances, so there's every chance that the 29-year-old continues to get more chances in the team over the coming heavy schedule.
In a more central role against the Dons he excelled and it's something that Rangers should pursue going forward. They may well have found the ideal creative link to bring their attacking prowess to the next level domestically.
Competition is fierce, but if Stewart can continue to impress in training and in matches, he's now well placed to make a big Gers impact this season.
