Preheat oven to 425°. In a small bowl, stir together garlic, rosemary, fennel seed, salt, red pepper, and lemon zest. In a large bowl, combine Brussels sprouts, carrot, and shallot; sprinkle with 1 tablespoon garlic mixture, tossing to coat. Set aside. Rub pork tenderloin with remaining garlic mixture.Wrap bacon around tenderloin, overlapping slices slightly.
In a 12-inch cast-iron skillet, heat ½ tablespoon olive oil over medium-high heat. Add tenderloin; cook until browned on all sides, 1 to 2 minutes per side. Remove from heat. Add vegetables to skillet; drizzle with remaining ½ tablespoon olive oil.
Bake until a meat thermometer registers 140° and vegetables are tender, approximately 25 minutes. Let stand 10 minutes before slicing.
