Preheat your oven to 425°F.
Mince the garlic cloves as finely as possible.
In a small bowl, whisk together 1 tablespoon of the olive oil with the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper to form a thick herb paste.
Pat the tri-tip roast completely dry with paper towels and rub the herb paste evenly over all sides of the meat.
Heat a large oven-safe skillet over medium-high heat and sear the roast for 3 minutes per side until a deep golden crust forms.
Transfer the skillet directly into the oven and roast for 12 to 15 minutes, or until the internal temperature reaches 130°F for medium-rare.
While the meat is roasting, spread the asparagus on a baking sheet, drizzle with the remaining olive oil, and roast for 10 minutes until tender and slightly charred.
Remove the roast from the oven and transfer it to a cutting board to rest for at least 10 minutes to lock in the juices.
Slice the tri-tip thinly against the grain and serve immediately alongside the roasted asparagus.
