Pat the sirloin steaks dry with paper towels. This helps to achieve a good sear.
In a small bowl, mix the olive oil, minced garlic, rosemary (or thyme), salt, pepper, paprika, and onion powder.
Rub the mixture evenly over both sides of each steak. Let the steaks sit at room temperature for about 30 minutes to marinate. This step helps the flavors to penetrate the meat and ensures even cooking.
Preheat the Grill:
Preheat your grill to high heat (about 450-500°F or 230-260°C). If using a charcoal grill, ensure the coals are evenly distributed and covered with a layer of white ash.
Grill the Steaks:
Place the steaks on the hot grill. For medium-rare steaks, grill for about 4-5 minutes per side. Adjust the time depending on your preferred doneness level:
Rare: 3-4 minutes per side
Rare: 3-4 minutes per side
Well Done: 7-8 minutes per side
Use tongs to flip the steaks; avoid using a fork as it can pierce the meat and release juices.
Rest the Steaks:
Remove the steaks from the grill and let them rest on a cutting board or plate for about 5 minutes. This allows the juices to redistribute throughout the meat, making it more tender and flavorful.
Serve:
Slice the steaks against the grain (the direction of the muscle fibers) to ensure tenderness. Serve with your favorite sides and enjoy!
Tips:
For extra flavor, consider adding a compound butter (butter mixed with herbs and garlic) on top of the steak just before serving.
You can also use a meat thermometer to ensure the steaks reach your desired level of doneness:
Rare: 125°F (52°C)
Medium Rare: 135°F (57°C)
Medium: 145°F (63°C)
Medium Well: 150°F (66°C)
Well Done: 160°F (71°C) or higher
Feel free to adjust the seasoning to your taste or experiment with different herbs and spices. Enjoy your grilled sirloin steak!
