Mr Atkinson, who recently left the five-star Rockliffe Hall, near Darlington, took a break from his latest venture to entertain the crowds at the Milton Street event today.
The chef, who is due to open his own restaurant on Newcastle’s Quayside later this year, is also the patron of Saltburn Farmer’s Market.
Mr Atkinson gave cooking demonstrations at 11.30am and 1.30pm to the crowds who packed out the street festival.
For food lovers, North-East producers were selling cheese, wine, meat, baked goods and sweet treats at the event.
Other attractions included Saltburn’s own Greedy Bassets Kitchen and Nobia African cuisine, run by Ghana born Nobia Deprez, who lives in Middlesbrough.
There were also picnic tables and live music so that visitors could relax throughout the day at the street-party style event.
