The History of Fajitas and Casseroles

Back in the 1930s, Mexican ranch workers in Texas—called “vaqueros”—used to grill tougher meat cuts over fires and wrap them in tortillas with onions and peppers. That was the first fajitas. Over the years, folks swapped in chicken since it’s easy to cook and soaks up flavors well.

Casseroles have been a fixture in American kitchens for ages. They’re the go-to for quick, filling meals that feed everyone with barely any cleanup. Putting fajita flavors into a casserole was a no-brainer for home cooks who wanted that spicy Tex-Mex taste in an easy one-dish meal. It’s comfort food at its finest.
