Celebrity chef Tom Colicchio’s Long Island home was vandalized after he displayed a yard sign for a Democrat running for Congress.

Someone with a political ax to grind scrawled “Cuomo = Death to America” on the pavement outside the “Top Chef” head judge’s posh Mattituck home in North Fork, “Trump” on the street and “Go home,” according to the Suffolk Times.

The Southold Highway Department cleaned up the graffiti, but not before neighbor Linda Burke snapped a few photos with her cellphone.

“I went for a walk to relax and clear my head. I really think it’s sad that people have to resort to that kind of communication,” she told the paper.

Colicchio, 56, later tweeted to his 926,000 followers that the vandalism “was in response for putting a @perrygershon yard sign up,” referring to the candidate running against Republican Lee Zeldin in the 1st Congressional District.

“What say you @leezeldin also my wife’s name a cross and a Jewish Star,” the noted chef added.

The graffiti also appeared to target Colicchio’s wife, Lori Silverbus, who also tweeted about the incident.

“Woke up this a.m. to a swath of hate speech painted across the property I share with @tomcolicchio and our 2 little boys,” she wrote.

“Cute touch: my name & a defaced Jewish star. Wake up USA: POTUS tacitly applauds this. THIS is whats at stake in the upcoming elections. #Vote2018 #NeverAgain,” she added.

For his part, Zeldin posted a response on Facebook, saying that “this coward needs to be identified and prosecuted.”

“Settle your scores at the ballot box in our great country! There is no place whatsoever for actions like this in our political discourse,” he wrote.

“Speaking from personal experience, as someone who is Jewish and yet still has been disgustingly called a Nazi and Nazi Sympathizer a few thousand times in the past 12 months, and having been targeted and my family targeted several times with death threats in the last year and a half, I know all too well what it is like to be the recipient of this hate and it is horrible and must end in our great country.”

Southold Police Chief Martin Flatley said the Suffolk County police Hate Crimes Unit was assisting his agency in the probe — though the incident was not classified as a hate crime.

On Facebook, Gershon said: “This cowardly and repugnant act does not represent the moral values of our community. I urge an aggressive investigation that identifies the perpetrators, and brings them to justice.”

He added: “Our President should be setting a good example for the rest of us, not associating himself with criminals. … Symbols of hatred must be condemned, whether at political events, or on a lawn in Mattituck.”

Colicchio did not immediately return a message from The Post.
