Creating the perfect sirloin steak is straightforward when you follow these simple steps:

1. Prepare the Steaks: Remove the sirloin steaks from the refrigerator and let them come to room temperature for about 20-30 minutes.
2. Season the Steaks: Pat the steaks dry with paper towels. Rub each steak with olive oil, then generously season both sides with salt and black pepper.
3. Add Aromatics: Sprinkle the minced garlic, rosemary, and thyme evenly over the steaks, pressing lightly to adhere.
4. Preheat the Skillet or Grill: Heat a heavy skillet (preferably cast iron) or grill over high heat until very hot. If using a skillet, add a small amount of oil to coat the bottom.
5. Sear the Steaks: Place the steaks in the hot skillet or on the grill. Sear for about 4-5 minutes without moving them, creating a nice crust.
6. Flip the Steaks: Turn the steaks over and cook for another 4-5 minutes for medium-rare. Adjust the cooking time for your preferred doneness (3-4 minutes for rare, 5-6 for medium, and 7-8 for well-done).
7. Optional Basting: For extra flavor, add a tablespoon of butter to the skillet in the last few minutes of cooking. Spoon the melted butter over the steaks while they cook.
8. Check the Temperature: Use a meat thermometer to check the internal temperature: 130°F for medium-rare, 140°F for medium, and 160°F for well-done.
9. Rest the Steaks: Once done, transfer the steaks to a plate and cover loosely with foil. Let them rest for 5-10 minutes to allow the juices to redistribute.
10. Slice and Serve: After resting, slice the steaks against the grain and serve with your favorite sides.
