01 - Set oven to 400°F (200°C)
02 - Generously season the rack of lamb with salt and freshly ground black pepper on all sides
03 - Heat 1 tablespoon olive oil in a large ovenproof skillet over medium-high heat. Sear the lamb for 2 to 3 minutes per side until deeply browned. Remove from heat and allow to cool slightly
04 - In a mixing bowl, combine breadcrumbs, parsley, rosemary, thyme, garlic, lemon zest, salt, and pepper. Stir in 2 tablespoons olive oil until the mixture holds together
05 - Brush the seared lamb with Dijon mustard on the meaty side. Press the herb mixture firmly onto the mustard-coated surface, forming an even, compact crust
06 - Place the lamb, crust side up, in the skillet or on a baking sheet. Roast in the preheated oven for 18 to 22 minutes for medium-rare (internal temperature 130°F), or until reaching desired doneness
07 - Remove from oven and tent loosely with aluminum foil. Rest for 10 minutes before slicing into individual chops
08 - Slice and serve immediately, garnishing with additional fresh herbs if desired
