In a small bowl, combine 1 tablespoon of olive oil, minced garlic, rosemary, thyme, salt, and pepper. Rub this mixture all over the sirloin steak.
On a separate part of a baking sheet (or on a separate baking sheet), toss the trimmed asparagus spears with the remaining 1 tablespoon of olive oil, salt, and pepper.
Place the seasoned steak on the baking sheet alongside the asparagus.
Roast for 12-18 minutes for medium-rare, or until the steak reaches your desired level of doneness (use a meat thermometer). The asparagus should be tender-crisp after about 10-15 minutes; remove it earlier if needed.
Let the steak rest for 5-10 minutes before slicing against the grain. Serve immediately with the roasted asparagus.
