The Sourdough Star features a 100 percent all-beef patty, charbroiled over an open flame, topped with crispy bacon, classic sauce, caramelized onions, melted American cheese, lettuce, tomato, and mayonnaise on toasted sourdough bread.
You can also get the Double Sourdough Star, which comes with two, 100 percent all-beef patties and two slices of melted American cheese, plus all the other standard toppings.
You can find both Sourdough Star burgers at participating Carl’s Jr. locations for a limited time.
