Preheat your oven to 400°F (200°C).
Trim the woody ends from the asparagus spears and place them on a parchment-lined baking sheet.
Drizzle the asparagus with extra virgin olive oil and sprinkle with garlic powder and a pinch of salt.
Roast the asparagus for 12 to 15 minutes until tender and slightly golden.
While the asparagus roasts, pat the bison steak dry with paper towels and season both sides with sea salt and black pepper.
Heat a heavy cast-iron skillet over medium-high heat until it is very hot and just beginning to smoke.
Place the bison in the skillet and sear for 3 to 4 minutes per side for medium-rare doneness.
Reduce the heat to medium and add the ghee, minced garlic, rosemary, and thyme to the skillet.
Tilt the pan slightly and continuously spoon the melting herb butter over the steak for 1 minute to infuse the meat.
Remove the steak from the pan and let it rest on a cutting board for 5 minutes to allow the juices to redistribute.
Slice the bison against the grain and serve alongside the roasted asparagus, drizzling any remaining pan butter over the top.
