Combine the smoked paprika, chili powder, kosher salt, ground cumin, and black pepper in a small bowl.
Mix thoroughly to create the steak seasoning blend.
Pat the sirloin steak dry with paper towels, removing any moisture.
Rub the seasoning mix evenly over both sides of the steak.
Preheat your grill to high heat, around 450°F.
Brush the grill grates with olive oil to prevent sticking.
Place the steak on the grill and sear it for 2-3 minutes on each side.
Achieve a nice crust without overcooking the inside.
After searing, reduce the grill's heat to medium and cook for an additional 3-5 minutes per side.
