Glasgow was second and Wolverhampton third following a three-month judging process.
Bradford, which has around 200 curry restaurants, was helped by local crisp maker Seabrook and its limited-edition chicken karahi flavour crisp, produced with Akbar’s restaurant.
For the first time, the annual awards recognised takeaway restaurants.
In Bradford, the top takeaway award went to Sizzlers Pizza and Balti Hut.
Customer restaurant of the year went to Bilash of Wolverhampton with previous winner Keighley’s Shimla Spice second.
Event organiser Peter Grove said: “This year’s competition was tougher than ever, with 22 cities bidding to be crowned Curry Capital of Britain.
“We’re delighted to see Bradford chosen by the public.”
The win for Bradford takes its total number of victories to four, the same as Glasgow.
Bradford took the title with 83.6 points out of a possible 100. Sheffield came tenth.
Patricia Tillotson, Bradford Council’s visitor economy manager, said: “Our bid was an incredibly strong submission and we’re immensely proud of our efforts.
“The 2013 restaurants and the team representing the city in the last 12 months have worked incredibly hard on charitable events which included a charity dinner and a Poppadomathon, which have all contributed to us winning.”
Restaurants that supported the bid included Aagrah, Akbar’s, Kiplings, Omar’s, Shimla Spice and Zouk.
Coun Susan Hinchcliffe, whose portfolio includes employment and culture, said: “I want to thank our superb restaurants, the Bradford tourism team and of course Seabrook crisps for making the bid that extra bit special.”
