A review of the Burger King sandwich by the Chicago Tribune verified these claims and also stated that the ingredients of the newer sandwich were of better quality than those of the McDonald's product. The Double Supreme was advertised with a direct attack on the Big Mac, using the claims that it had 75% more beef and less bread than the McDonald's sandwich.

The sandwich was reformulated after the initial test run, removing the center roll. Because its patties are flame-broiled and larger than McDonald's grill fried and seasoned patties, and the formulation of the 'King Sauce' was different from McDonald's 'Special sauce', the sandwich had a similar, but not exact, taste and different caloric content. Originally, the burger had a look and composition that resembled the Big Mac: it had two beef patties, 'King' sauce, lettuce, cheese, pickles and onions on a three-part sesame seed bun. Hoping to build on improving sales of Burger King and take advantage of perceived market weakness of McDonald's, the chain introduced the Double Supreme as part of an advertising blitz against its competitor. Burger King's take on rival McDonald's well-known Big Mac sandwich was released as a test product in January 1996 when McDonald's was having difficulties within the American market. The sandwich that would eventually become the Big King was preceded by a similar sandwich called the Double Supreme cheeseburger. McDonald's Big Mac sandwich, the inspiration for the Big King The burger was introduced by Australian Burger King franchise Hungry Jack's in 2020 under the name Big Jack, with a slightly altered recipe and a controversial marketing campaign that highlighted its similarity to the Big Mac, leading to a trademark infringement lawsuit being filed by McDonalds. To promote continuing interest in the product, Burger King occasionally releases limited-time variants on the Big King. There was a chicken variant of the sandwich in the United States and Canada. The Big King XXL is part of a line of larger double cheeseburgers known as the BK XXL line the XXL line was the center of controversy over product health standards and advertising in Spain when first introduced. One such example sold by BK's European arm of the company is a larger version of the sandwich called the Big King XXL, based on the company's Whopper sandwich. When the Stacker line was discontinued in the United States shortly after, the Big King returned in November 2013 as a permanent product.Дespite being off the menu in the United States for several years, the product was still sold in several other countries under several names during the interim of its unavailability in the United States. A later restructuring eliminated the King Supreme in favor of its new BK Stacker line of sandwiches. The product was renamed King Supreme in 2001 when it was slightly reformulated as part of a menu restructuring during a period of corporate decline. It was given its current name when the product was formally introduced in September 1997, but maintained the more conventional double cheeseburger format. It was later reformulated as a more standard double burger during the latter part of product testing in 1997. During its testing phase in 1996вЂ“1997, it was originally called the Double Supreme and was configured similarly to the McDonald's Big Mac-including a three-piece roll. As of March 2019, it is sold in the United States under its 1997 Big King XL formulation. The Big King sandwich is one of the major hamburger products sold by the international fast-food restaurant chain Burger King, and was part of its menu for more than twenty years.
