biggest burger make-over in decades

McDonald's has revealed it is making some of the biggest changes to its best-selling burgers in decades.

Here's what's changing...

The fast food giant is shaking up how it cooks and prepares classic items like the

Cheeseburger

Big Mac

Quarter Pounder with cheese

Tighter sear on the grill for hotter, sizzling and juicier beef patties for maximum flavours.

BEEF PATTIES

New processes on the grill involve adding white onions on top of patties as they cook for added colour and charred flavour.

GRILLED ONIONS

Fresh lettuce straight from the fridge for a crunchier taste.

LETTUCE

Hotter beef patties will make the cheese more melted, creating a smoother texture.

CHEESE

The changes are already being rolled out across all its 1,450 restaurants in the UK.

NEW BUNS

Buttery, brioche-style recipe and freshly toasted.
