01 - Preheat oven to 400°F.
02 - Season the rack of lamb generously with salt and 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 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 side, forming an even crust.
06 - Place the lamb, crust side up, in the skillet or on a baking sheet. Roast in the oven for 18 to 22 minutes for medium-rare, until internal temperature reaches 130°F.
07 - Remove from oven and tent loosely with aluminum foil. Rest for 10 minutes before slicing into individual chops.
08 - Serve immediately, garnished with additional fresh herbs if desired.
