Preheat your oven to 400°F and prepare the asparagus by trimming off the woody bottom ends.
Place the asparagus on a baking sheet, drizzle with avocado oil, and season with a pinch of sea salt and black pepper.
Roast the asparagus for 10-12 minutes until tender and slightly charred.
While the vegetables roast, pat the sirloin steak completely dry with paper towels and season both sides with the remaining sea salt and black pepper.
Heat a cast-iron skillet over medium-high heat until it begins to smoke slightly.
Place the steak in the hot skillet and sear for 3-4 minutes per side for medium-rare, or until it reaches your preferred internal temperature.
Reduce the heat to medium-low and add the ghee, smashed garlic cloves, rosemary, and thyme to the side of the pan.
Tilt the skillet slightly and use a large spoon to continuously baste the steak with the melted herb ghee for about 60 seconds.
Remove the steak from the skillet and let it rest on a cutting board for 5 minutes to allow the juices to redistribute.
Slice the steak against the grain and serve alongside the roasted asparagus.
