A Brooklyn pastry chef with a male-sounding name was hired sight unseen at a Manhattan restaurant because bosses thought she was a man — and promptly fired when she showed up and they learned she was a woman, a lawsuit claims.

Ryans McGovern says she was hired for the $16-an-hour gig at Hudson Hall’s Mercado Little Spain in February, and told to wait for information about training and orientation.

When she showed up for orientation weeks later, though, a manager allegedly told McGovern, “Oh you’re a girl. I thought you were a guy.”

A second supervisor specified that the restaurant managers “thought you were a guy because of your name,” McGovern claims.

Two days later, the job offer was rescinded, McGovern charges in a discrimination lawsuit seeking unspecified damages.

“There was never any discrimination against Ms. McGovern, which any litigation will bear out,” a spokeswoman for the restaurant said.
