What is a casserole?

Technically any dish made in a casserole dish and baked in an oven would be called a casserole. A casserole can have layers such as our Easy Tex Mex Fajita casserole or it can be made with an evenly distributed combination of vegetables, protein (most often meat), and starch. Casseroles are a one-pot dish thought to date back to the eighteenth century although the term has existed much longer than that.

Common in French cooking ‘cassa’ or ‘pan’ dishes with combined ingredients were popular in France. The actual casserole was thought to have been invented by a French-Canadian immigrant in the late eighteen hundreds. It quickly became a go-to in the US for the money-saving aspects during the depression and world wars of the 20th century. With its ease of preparation and the ability to make a low-cost, one-pan dish in the oven, the casserole became a hit and started showing up in the cookbooks of that period. 

History of Fajitas

Fajitas are thought to have originated in Texas as an alternate use of the meat cut commonly called skirt steak. It is a traditional Texan American dish of beef cooked on a grill and cut into strips. A similar dish in Mexico is known as arracheras, which is Spanish for skirt steak or carne asada when grilled.

The skirt steak was once considered a throwaway along with the head, entrails, and trimmings of fat and cartilage during the slaughter of cattle. As was a common practice when cowboys and Mexican Vaqueros were herding cattle the camp cook would take the throw-away parts from a butchered cow and cook them on a campfire grill along with onions, peppers, or whatever vegetables were available. Often the vaqueros were partially paid with the leftover meat trimmings and skirt steak. 

The first commercial fajita emerged in the late sixties when an enterprising meat market manager in Austin Texas first put the practice of grilling the skirt steak with pepper and onions into a specialty dish to sell at free-standing concession stands. Restauranteurs quickly jumped on the fajita bandwagon and fine-tuned them into the sizzling fajita dish we know today.  Of course, now we have many varieties of fajitas from shrimp to chicken and even veggie fajitas.

I love fajitas and when I first tried them, they were still scarce in some areas as a readily available restaurant dish. So, I started making them myself and still do on occasion. Back then they were a time-consuming dish to prepare at home as you rarely found the meat cuts of beef strips that are common in markets today, so you did your own cuts, which meant trimming and cleaning the skirt steak slab first. There was also no commercial fajita mix that is common today. I used lemon pepper and other spices that I blended myself.
