Step 1

Let the steaks sit at room temperature for 20 minutes.

Step 2

Preheat the oven to 450 degrees F. Season the steaks on both sides with salt and pepper to taste.

Step 3

Heat a heavy pan such as a cast iron skillet over high heat.

Step 4

Add the oil to the pan. Place the steaks in the pan in a single layer.

Step 5

Cook for 2-3 minutes per side or until browned.

Step 6

Add the butter to the pan. After the butter has melted, add the garlic and rosemary to the pan. Stir to combine.

Step 7

Spoon the butter mixture over the steaks. Insert a thermometer into the thickest part of one of the steaks. Place the meat in the oven and bake for 5-7 minutes or until the thermometer registers 140 degrees F for a medium steak.

Step 8

Remove the pan from the oven. Let the steak rest for 5 minutes. Spoon the pan drippings over the steak, then serve immediately.
