Start by removing the sirloin steak from the refrigerator and letting it come to room temperature for about 30 minutes.
Pat the steak dry with paper towels, drizzle olive oil over both sides, and sprinkle BBQ dry rub seasoning evenly.
Preheat your griddle over medium-high heat for about 5-10 minutes.
Carefully place the steak on the hot griddle and let it sear for about 4-5 minutes on the first side.
Flip the steak using tongs and cook on the other side for an additional 3-5 minutes.
Once cooked, remove the steak from the griddle and let it rest for 5-10 minutes.
After resting, slice the steak against the grain and serve with your favorite sides.
