But Kozior, a theater-assistant and Central Bucks graduate, wasn't able to make it into the show's final six Wednesday evening, failing to impress the judges with her calamari.
"I did my best and that's all I could do. Still had a lot to learn. Thank YOU all for standing behind me & remember, in the end #goodgirlswin," she wrote on Twitter after the episode aired.
That might have been a reference to competitor fellow Pennsylvanian Krissi Biasello, a Philadelphia paralegal who had functioned as Kozior's arch-rival for much of the competition.
"Be nice, please. Try to be nice," Kozior had told her Wednesday night before departing.
Kozior, the only vegetarian in the competition, had impressed the show's judges several times with both meat and non-meat dishes. She had the best dish in last week's episode, a stuffed quail that led judge Joe Bastianich to label her one of the competition's frontrunners.
If past seasons of MasterChef are any indication, Kozior could appear one more time, as a sort of cheering section for the top two competitors in the final episode.
