According to a spokesperson, Ms Ray, her husband and her dog are all safe, though the damage to the house is yet to be fully assessed.
The fire reportedly began at around 7pm on Sunday night, and had soon spread to the whole house.
The multi-million-dollar home in Lake Luzerne, west of the city of Glens Falls, was reportedly designed by Ms Ray herself.
In a video for her show in April, she told the audience that she “drew this house on a piece of paper and decorated it before it was ever built”.
Ms Ray has been live-streaming cookery sessions during the coronavirus pandemic, using an enhanced internet connection to broadcast over Zoom.
“There ain’t a lot of hair and make-up going on here,” she told local station WNYT-TV, “so it’s a different kind of intimacy that I think we’ve established with our viewers and honestly it feels good.”
