Which burger chain created the Big King as a rival to McDonald’s Big Mac?

Burger King created the Big King as a rival to McDonald’s Big Mac.

The Big King is a stacked hamburger with two beef patties, cheese, lettuce, onion, pickles, and a special sauce. Its structure deliberately resembles the Big Mac, making it one of the clearest examples of a fast-food chain responding to a competitor’s signature product.

Burger King introduced the Big King in the United States in 1997. The sandwich has appeared under different names and with variations in different markets, including versions using a sesame-seed bun and a sauce modeled on the flavor profile of the Big Mac.

The Big King should not be confused with Burger King’s Whopper. The Whopper is the chain’s older flagship burger, introduced in 1957, while the Big King was designed specifically as a competing double-patty sandwich.
