Instructions

1. Step 1: Pat 12 oz beef sirloin steak dry with paper towels, then season both sides with 1 tsp salt and 1/2 tsp black pepper.
2. Step 2: Heat 2 tbsp olive oil in a heavy skillet over medium-high heat until shimmering, about 2 minutes.
3. Step 3: Add the steak and sear for 4 minutes on the first side without moving it to develop a deep crust.
4. Step 4: Flip the steak and add 3 tbsp unsalted butter, 3 minced garlic cloves, and 2 sprigs fresh rosemary to the pan.
5. Step 5: Tilt the pan slightly and spoon the melted butter and garlic over the steak continuously for 3-4 minutes until it reaches medium-rare (135°F internal temperature).
6. Step 6: Remove the steak from the pan and let it rest for 5 minutes before slicing to retain juices.
