Ingredients
- 2 Top Sirloin Steaks 1.5 to 2 inches thick
- 1 tbsp Avocado Oil or any high smoke point oil
- 2 tsp Coarse Kosher Salt
- 1 tsp Freshly Cracked Black Pepper
- 4 tbsp Unsalted Butter
- 3 cloves Garlic minced or smashed
- 2 sprigs Fresh Rosemary or Thyme
- 1/2 Lemon optional, for finishing
Instructions
- Preparation: Remove steaks from the fridge 30 minutes before cooking. Pat them completely dry with paper towels.
- Seasoning: Rub the steaks with avocado oil, then season generously with kosher salt and black pepper on all sides.
- Preheating: Heat your grill or cast-iron skillet to high heat (around 450°F / 230°C) until it starts to slightly smoke.
- The Sear: Place steaks on the hot surface. For medium-rare, grill for 4-5 minutes without moving them to develop a crust.
- The Flip & Baste: Flip the steaks. Add butter, garlic, and rosemary to the pan (or on top of the meat if using a grill). Cook for another 3-4 minutes.
- Temperature Check: Use a meat thermometer to ensure the internal temperature has reached 135°F (57°C) for medium-rare.
- The Rest: Transfer the steaks to a wooden board and let them rest for at least 5-10 minutes before slicing against the grain.
