For the juiciest results, take your sirloin steaks out of the refrigerator 30-40 minutes before cooking. This helps them cook more evenly.
Drizzle each steak with olive oil, then rub it all over. Sprinkle generously with your favorite steak seasoning, or simply use kosher salt and pepper to taste. Don't be shy with the flavor!
Get your BBQ grill nice and hot, aiming for a high heat of approximately 500°F.
Place the seasoned steaks on the hot grill at a 45-degree angle. Let them cook for 2 minutes to get those beautiful initial grill marks.
Rotate the steaks 90 degrees and cook for another 2 minutes. This creates the classic, professional-looking cross-hatch pattern.
Flip the steaks over and repeat steps 4 and 5 on the other side, grilling for 2 minutes at a 45-degree angle, then rotating 90 degrees and grilling for another 2 minutes.
Reduce the grill heat to medium-low. Continue cooking the steaks for an additional 4-6 minutes for a perfectly juicy medium-rare (internal temperature of 135°F). Adjust cooking time for your desired doneness using an instant-read thermometer.
Top each cooked steak with a pat of butter (or herbed butter) and cover loosely with foil. Let them rest for 5 minutes before slicing and serving. This allows the juices to redistribute, ensuring every bite is incredibly tender and flavorful!
