Preheat your oven to 450°F to ensure a proper sear on the meat.
In a small bowl, combine the ghee, minced garlic, chopped rosemary, thyme, sea salt, and black pepper to form a paste.
Pat the prime rib roast dry with paper towels and rub the herb ghee paste evenly over the entire surface.
Place the roast in a shallow roasting pan and sear in the oven for 15 minutes.
Reduce the oven temperature to 325°F and continue roasting until the internal temperature reaches 130°F for a perfect medium-rare.
Remove the roast from the oven and transfer it to a cutting board, allowing it to rest for at least 15 minutes.
While the meat rests, place the asparagus on a baking sheet and roast at 400°F for 8 to 10 minutes until tender.
Slice the prime rib against the grain and serve immediately alongside the roasted asparagus spears.
