What’s in a McDonald’s Big Mac?
The McDonald’s Big Mac® combines simple ingredients with its signature recipe to create one of the brand’s most recognisable burgers. Every Big Mac® is made with two 100% British and Irish beef patties, Big Mac® sauce, Cheddar cheese, fresh iceberg lettuce, pickles, onions, and a toasted three layer sesame seed bun.
100% British and Irish Beef Patties
The Big Mac® features two seasoned beef patties made from 100% British and Irish beef, cooked on the grill and lightly seasoned with salt and pepper for a rich, savoury flavour.
Big Mac® Sauce
The famous Big Mac® sauce delivers the burger’s signature taste with a creamy blend of gherkins, free range egg yolk, mustard, spices, and seasonings.
Three Layer Sesame Seed Bun
Unlike most burgers, the Big Mac® is served in a toasted three layer sesame seed bun. The extra middle bun helps separate the beef patties while adding the burger’s distinctive appearance.
Cheese and Fresh Toppings
A slice of processed Cheddar cheese, crisp iceberg lettuce, tangy pickle slices, and finely chopped onions complete the burger. Together, these ingredients balance the rich beef with fresh texture and flavour in every bite.
Together, these carefully selected ingredients create the balanced combination of savoury beef, creamy sauce, crisp vegetables, melted cheese, and soft sesame seed bun that has defined the Big Mac® for more than five decades.
