Preheat your oven to 400°F and prepare a baking sheet with parchment paper.
Trim the woody ends from the asparagus and finely mince the garlic, rosemary, and thyme.
Pat the sirloin steak dry and season both sides with half of the sea salt and black pepper.
In a small bowl, whisk together the minced herbs, garlic, and half of the olive oil to form a thick paste.
Heat a cast-iron skillet over medium-high heat and sear the steak for 2-3 minutes per side to develop a deep golden crust.
Transfer the steak to the baking sheet, spread the herb paste over the top, and arrange the asparagus around it.
Drizzle the asparagus with the remaining olive oil and season with the remaining salt and pepper.
Roast for 8-10 minutes until the beef reaches your preferred temperature and the asparagus is tender.
Allow the steak to rest for 5 minutes before slicing against the grain to ensure maximum juiciness.
