Fajitas originated in Texas as part of Tex-Mex cuisine, traditionally made with grilled skirt steak and served with peppers and onions. The name “fajita” comes from the Spanish word faja, meaning “strip” or “belt.” Over time, chicken became a popular alternative due to its affordability and mild flavor. The sheet pan version is a modern adaptation that embraces oven roasting for simplicity while preserving the essence of traditional fajitas.
