Celebrity chef Gordon Ramsay Monday announced he was ending his restaurant-rescue show "Kitchen Nightmares," which has aired in separate British and American versions for a decade.

"I've had a phenomenal 10 years making 123 episodes, 12 seasons, shot across 2 continents, watched by tens of millions of people and sold to over 150 countries," Ramsay, 47, wrote on his website. "It's been a blast but it's time to call it a day."

Calling it "the show that really propelled my TV career," he thanked "the amazing team behind the series" as well as the show's viewers. "I'm glad I've been able to entertain and hopefully help a few people along the way," he wrote. "It's sad to say goodbye to 'Kitchen Nightmares' but I'll be continuing with my other shows," which include the competitions "Hell's Kitchen" and "MasterChef."

The Scottish chef-restaurateur's series premiered on the UK's Channel 4 in 2004 as "Ramsay's Kitchen Nightmares," and spun-off an American version, "Kitchen Nightmares," on Fox in 2007. In both, he would visit and spend a few days at floundering restaurants, often having to overcome owners' resistance to change. In one memorable 2013 episode, featuring Amy's Baking Company in Scottsdale, Ariz., he walked out when it became apparent that the highly difficult and eccentric proprietors were rebuffing his efforts.

In a jocular account that accompanied his post, he estimated the series had had 10,197 swear words and 0.4 gallons of tears, and that he'd suffered two ulcers and consumed 2.3 liters of Pepto Bismol and 234 Zantacs.
