McDonald's introduced the McRib sandwich in the United States in 1981.
The McRib was developed as a boneless pork sandwich shaped to resemble a rack of ribs. Its bun, barbecue sauce, onions, and pickles gave it a flavor profile different from McDonald's beef burgers. The product was initially introduced as a limited menu item rather than as a permanent nationwide staple.
The sandwich became notable for its periodic returns. McDonald's could build anticipation by bringing it back for particular promotions or markets, making availability part of the product's branding story.
The McRib's name describes the visual concept rather than the presence of traditional rib bones. It is also distinct from the Quarter Pounder and Big Mac, which are more consistently associated with the chain's permanent core menu in the United States.
