"McDonald's Nationwide Launch of New & Improved Burgers"

McDonald's has rolled out its revamped hamburgers, including the Double Big Mac, nationwide, featuring softer, toasted buns, melted cheese, fresher tomatoes and lettuce, and caramelized onions. The changes aim to make the burgers more flavorful, with adjustments to the cooking process and grill settings. This marks the first major update to the burger lineup since 2018, and the revamped burgers were initially introduced in Australia, Canada, and Belgium before being made available in larger U.S. cities.
