Preheat your oven to 400°F.
Place the asparagus spears on a parchment-lined baking sheet, drizzle with half of the ghee (melted), and sprinkle with a pinch of the sea salt.
Roast the asparagus for 12 minutes until tender and slightly charred.
While the vegetables roast, season the salmon fillet on both sides with the remaining sea salt and black pepper.
Heat a heavy skillet over medium-high heat and add the remaining ghee.
Place the salmon in the skillet skin-side up and sear for 4 minutes until a golden-brown crust forms.
Flip the salmon and add the minced garlic, chopped parsley, chopped dill, and lemon juice to the pan.
Tilt the pan slightly and use a spoon to continuously baste the salmon with the bubbling herb butter for another 3 minutes until cooked through.
Serve the salmon immediately alongside the roasted asparagus, drizzling any remaining herb butter from the pan over the top.
