The TV chef says he wrote to the couple saying he would “sort the food” and bring the best of “British and American chefs together” for their grand nuptials at Windsor Castle in May.
However, the 43-year-old father-of-five claims he didn’t get a reply from the Duke and Duchess of Sussex.
“That is true story,” the Naked Chef told Channel 4’s Sunday Brunch presenters Simon Rimmer and Tim Lovejoy, who burst out laughing.
Jamie, appearing as a guest on the show, then shrugged his shoulders and added: “I would have done it for free.
“I like a bit of a moment. I would have got all the American gang over, we’ve got all the British dudes. It would have been the best brigade of kitchen ever.”
His fellow guests sympathised, with Emilia Fox jovially calling it a “massive missed opportunity”.
Tim Lovejoy then tried to soften the blow and said to Jamie: “I imagine they have all their chefs at Buckingham Palace doing it.”
Jamie, who didn’t seem too disheartened, replied: “They are very slick at protocol and getting those gigs done, so we probably were a bit renegade.”
The 600 guests at Harry and Meghan’s wedding were in fact served seasonal British classics made by a team of 30 staff.
Led by the Queen’s chef Mark Flanagan, the team sourced fresh ingredients from the Home Counties and lands associated with the Queen like Windsor.
But Mr Flanagan kept tight-lipped over exactly what he was serving.
He previously said: “The day of the wedding has fallen very kindly for us.
“All the British vegetables are just coming into season… and that’s been a point of focus for us.
“We know the couple wanted us to make sure we used all of the local seasonal produce as much as possible throughout their menu, and this recent good weather is really helping us to achieve that.
“(For) all their decisions, we purely made suggestions and the couple… they’ve tasted everything, they’ve been involved in every detail…
“We are using produce off Her Majesty’s estates and that features very much.”
