Preheat your oven to 400°F and line a baking sheet with parchment paper.
Trim the woody ends off the asparagus and place them on the baking sheet, tossing with a small amount of melted ghee and a pinch of salt.
Roast the asparagus for 12-15 minutes until they are tender but still have a slight snap.
While the asparagus roasts, pat the sirloin steak dry with paper towels and season both sides with the sea salt and black pepper.
Heat a cast-iron skillet over medium-high heat and add the remaining ghee.
Once the skillet is hot, sear the steak for 4-5 minutes per side for a medium-rare finish.
In the last 2 minutes of cooking, add the smashed garlic cloves, rosemary, and thyme to the pan.
Tilt the skillet and use a spoon to baste the steak repeatedly with the hot herb-infused ghee.
Remove the steak from the pan and let it rest on a cutting board for at least 5 minutes to lock in the juices.
Squeeze fresh lemon juice over the roasted asparagus and serve alongside the sliced steak.
