Which burger includes bacon as a key ingredient?

The bacon cheeseburger is specifically designed to include bacon as one of its primary ingredients. This burger typically features a juicy beef patty topped with both cheese and crispy bacon, enhancing the flavor and adding a satisfying crunch. This combination makes it a popular choice for guests looking for a hearty and flavorful option. Other burgers listed, such as the all American burger, smokehouse burger, and veggie burger, do not contain bacon, either focusing on different toppings or ingredients that cater to various preferences or dietary needs. Therefore, the inclusion of bacon in the bacon cheeseburger is what distinguishes it in this context.
