Which type of meat is primarily used in many of Carl's Jr.'s signature items?

The primary type of meat used in many of Carl's Jr.'s signature items is beef. This choice reflects the brand's focus on offering a variety of charbroiled hamburgers, which are a hallmark of their menu. Carl's Jr. is known for its substantial beef patties and creative burger toppings, making beef a central ingredient in many popular items, such as the famous Western Bacon Cheeseburger and the Original Thickburger.

While options like pork, chicken, and turkey are also available in some menu items, they do not define the core identity of the brand as strongly as beef does. The emphasis on beef aligns with the fast-food chain's market positioning in the competitive hamburger segment.
