The incident happened as the Geordie star was figuring out how to use a vegetable-slicing gadget on Saturday night, for a dinner for his best friend the next day.
"It was a complete disaster. I ended up slicing the top of my thumb off. God, it was painful," McPartlin said.
The star had hoped medics would be able to reattach his thumb, but after being rushed to the hospital he was told they would only be able to clean and dress the injury.
"It hurt like hell. There was a lot of blood," he said.
But despite the ordeal, McPartlin made sure the Sunday roast went ahead as planned, adding: "I still got the meal on the table."
