Step 1

In a small bowl, stir together 3 tablespoons of the olive oil, rosemary, garlic, salt and pepper. Spoon mixture evenly over both sides of lamb chops. (You can do this up to 4 hours ahead.)

Step 2

Heat a large skillet (ideally cast iron) over medium-high heat until hot. Pour in remaining tablespoon of olive oil and swirl to coat. Add lamb chops in a single layer and cook 2 to 4 minutes on each side to desired doneness, 135°F for medium-rare.

Step 3

Transfer lamb chops to platter and let rest 5 minutes before serving.
