In a mixing bowl, season ground beef with Creole seasoning. Divide the meat into four equal portions and shape into balls, then flatten each into thin patties. In a skillet over medium-high heat, sear patties for 2 to 3 minutes per side until a well-browned crust develops and patties are cooked through.
