What is the primary coating on the catfish fillets?

The primary coating on the catfish fillets served at Texas Roadhouse is a Southern cornmeal mixture. This choice is correct as it reflects the traditional Southern style of preparing catfish, which often involves using cornmeal to create a crispy and flavorful crust. The use of cornmeal not only adds a distinct texture but also complements the mild flavor of the catfish, enhancing the overall dish. This preparation method is deeply rooted in Southern cuisine, making it a fitting choice for a restaurant that prides itself on offering authentic Southern-inspired dishes.

Additionally, while breadcrumbs, flour, and panko bread crumbs could theoretically be used for coating, they do not capture the essence of the Southern-style catfish that Texas Roadhouse aims to showcase. The cornmeal coating is what sets this dish apart and aligns with the culinary traditions from which it originates.
