Remove lamb chops from refrigerator and let sit at room temperature for 15 minutes. Pat dry with paper towels and season both sides with salt and pepper.
In a small bowl, combine panko breadcrumbs, rosemary, thyme, garlic, and 2 tablespoons of olive oil. Mix until the herbs are evenly distributed.
Heat remaining 1 tablespoon olive oil in a large oven-safe skillet over medium-high heat. Sear lamb chops for 2 minutes per side until browned.
Brush the top of each lamb chop with Dijon mustard, then press the herb mixture firmly onto the mustard-coated side.
Transfer the skillet to a preheated 400°F oven and roast for 5-7 minutes for medium-rare (130°F internal temperature), or until desired doneness.
Remove from oven, tent loosely with foil, and let rest for 5 minutes before serving.
