History / Fun Facts
The traditional Chicken Parmesan, or Chicken Parmigiana, is believed to have been inspired by Italian immigrants in the early 20th century who adapted eggplant parmigiana into a meat-based version. It quickly became a staple of Italian-American cuisine, celebrated for its crispy chicken and rich tomato sauce. This casserole version simplifies the process while keeping the soul of the original dish intact — proving that comfort food can evolve without losing its heart.
