Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and place the spears on the baking sheet.
Drizzle the asparagus with half of the olive oil and sprinkle with a pinch of the salt and pepper, tossing to coat evenly.
Roast the asparagus in the oven for 10 to 12 minutes until tender and slightly charred.
While the asparagus roasts, pat the salmon fillet completely dry with a paper towel and season both sides with the remaining salt, pepper, and garlic powder.
Heat the remaining olive oil in a stainless steel or cast iron skillet over medium-high heat until the oil is shimmering.
Place the salmon skin-side down in the hot skillet and press down gently with a spatula for 10 seconds to ensure even contact.
Sear the salmon for 4 to 5 minutes without moving it until the skin is golden and crispy.
Carefully flip the salmon and cook for an additional 2 to 3 minutes until the internal temperature reaches 145°F.
Plate the salmon alongside the roasted asparagus and finish with a fresh squeeze of lemon juice over the entire dish.
