From July 20, Freeview homes will be able to watch the Food Network all day, rather than the previous four-hour programming block in the evenings. The channel is available at 49 on the Freeview electronic programme guide.
The Food Network UK launched on digital terrestrial television in July last year, joining its existing carriage arrangements on Sky and Freesat.
Owned by Scripps Networks, which also holds a 50% shareholding in pay-TV operator UKTV with BBC Worldwide, the channel offers a range of food entertainment shows, such as US programmes Drive-Ins and Dives, Man vs Food Nation, and Barefoot Contessa.
The UK network has also commissioned a range of more locally orientated content, such as Andy Bates Street Feasts and Reza, Spice Prince of India.
According to Scripps, the channel was sampled by more than 11m UK viewers on Freeview over the course of last year, with 3.3m tuning in each month.
"By expanding Food Network's on-air presence, we are not only providing viewers with round-the-clock food and lifestyle programmes, but we also enrich and strengthen the overall value of our subscription-free offer," said Guy North, the marketing communications director at Freeview.
Food Network Europe managing director Nick Thorogood added: "Today's news is a testament to the quality of our programming and Food Network UK's popularity and reputation amongst viewers.
"By extending our hours on this platform, all Freeview households will now be able to enjoy our great food entertainment all day, every day."
