It looks like only three, unless I’m forgetting someone who’s judged in the past. I’ve found the aforementioned Geoffrey Zakarian, with Aaron Sanchez and Amanda Freitag.
Yeah, it looks like Maneet Chauhanwill be grouped in with the judges to make up a foursome.
I guess none of the other judges wanted to be on the other side of the table, the big sissies 
Alex Guarneschelli did want to cook, but she said on Twitter on Sunday that the producers wanted one woman on the judging panel and so she let Amanda Freitag cook. Since she has her own stand-up cooking show & Freitag doesn’t (though Freitag should be an Iron Chef now, dammit) it makes certain sense.
I’ve been enjoying the Chopped series and think this All-Stars version will be great. Sometimes, though, I think you could prepare the best thing on the planet and the judges would criticize it. They seem so petty.
Since I’ve only seen her as a panelist on Food Network shows I’m concerned she might be, um, judgemental about - well about everything.
Of all the cooking shows I’ve seen, I find the format of Chopped the most appealing. I usually only watch the last few minutes of Iron Chef, if at all, for example.
She’s passionate about food. Her tweets about food remind me of how I talk about sex in the company of my closest girlfriends. Lots of things melting and soft and dripping and juicy in her tweets. 
No kidding, I saw her describe a cheese souffle on “Best Thing I Ever Ate” and thought she was going to have a cheesegasm right there on camera.
In one of the previews for the judges episode I just saw, they showed footage of Maneet as a Chopped judge?
Yeah, I didn’t remember seeing her as a judge on “Chopped,” just on “Next Iron Chef.”
Whoops.
