Preheat your oven to 425°F (218°C).
In a small bowl, combine the olive oil, minced garlic, dried rosemary, dried thyme, sea salt, and black pepper to create a paste.
Pat the tri-tip roast dry with a paper towel and rub the garlic-herb paste evenly over all sides of the meat.
Place the roast in a shallow roasting pan or a cast-iron skillet.
Roast in the oven for about 25-30 minutes, or until the internal temperature reaches 130°F for medium-rare.
While the beef roasts, place the asparagus spears on a small baking sheet, lightly mist with oil, and season with a pinch of salt.
Add the asparagus to the oven during the last 10-12 minutes of the beef's cooking time.
Remove the roast from the oven and let it rest on a cutting board for at least 10 minutes to lock in the juices.
Slice the beef against the grain and serve alongside the roasted asparagus.
