Pat the steaks dry with paper towels. This helps the spices adhere better and ensures a good sear.
In a small bowl, combine black pepper, smoked paprika, granulated garlic, granulated onion, chili flakes, and salt.
Rub the olive oil evenly over both sides of the steaks. Sprinkle the spice mixture over the steaks, pressing it into the meat to ensure it sticks well.
Heat your grill to high heat. If using a grill pan, heat it over high heat until it's smoking hot.
Place the steaks on the grill or grill pan. Cook for 4-5 minutes on each side for medium-rare, or adjust the cooking time to your preferred doneness.
Remove the steaks from the grill and let them rest for 5 minutes before slicing. This allows the juices to redistribute throughout the meat.
