To cook a delicious Black Angus ribeye steak, start by allowing the steak to come to room temperature. Preheat your grill or a heavy skillet over medium-high heat. Season the ribeye generously with salt and freshly ground black pepper. Grill or sear the steak for about 4-5 minutes per side, flipping only once, until it reaches your desired level of doneness (about 130°F (55°C) for medium-rare). Use tongs to handle the steak to preserve its juices. Once cooked to perfection, remove the ribeye from the heat and let it rest for a few minutes before slicing against the grain. Serve immediately to enjoy the juicy tenderness and robust flavor of Black Angus ribeye steak.
