Roasting lamb is simple, but a few small tricks can elevate the results.
- Bring the lamb to room temperature: Let the meat sit out for about 30 minutes before cooking so it roasts evenly.
- Score the fat lightly: Small shallow cuts allow garlic and herbs to flavor the meat more deeply.

This helps ensure the lamb cooks to the perfect temperature without overcooking.
