Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a small bowl, whisk together the olive oil, minced garlic, rosemary, thyme, sea salt, and black pepper to create a paste.
Pat the pork loin dry with paper towels and rub the garlic-herb mixture evenly over all sides of the meat.
Place the pork loin and the sliced carrots on the prepared baking sheet, ensuring the carrots are spread in a single layer.
Roast in the oven for 15 minutes.
Remove the sheet briefly to add the asparagus spears around the pork, then return to the oven for another 10 to 12 minutes.
Check the pork with a meat thermometer; it is ready when it reaches an internal temperature of 145°F (63°C).
Transfer the pork to a cutting board and let it rest for 5 to 10 minutes before slicing to keep the juices intact.
Serve the sliced pork alongside the roasted carrots and asparagus.
