📜 History of the Dish

The word “fajita” comes from Mexican cooking traditions and originally referred to grilled strips of beef skirt steak. The dish became popular in Texas during the 1930s and later developed into the famous Tex-Mex style we know today, using chicken, shrimp, vegetables, and different seasonings.

The casserole version is a modern adaptation created for convenience, combining traditional fajita flavors with the comfort of baked casseroles. It keeps the spirit of fajitas while making a dish that can easily feed a family.
