Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and place them on the prepared baking sheet.
Drizzle the asparagus with half of the extra virgin olive oil and sprinkle with a pinch of sea salt and black pepper, tossing to coat evenly.
Roast the asparagus in the oven for 12 to 15 minutes until they are tender and slightly charred at the tips.
While the vegetables roast, pat the salmon fillet completely dry with a paper towel to ensure a perfect sear.
Season both sides of the salmon with the garlic powder and the remaining sea salt and black pepper.
Heat the remaining olive oil in a high-quality non-stick or cast-iron skillet over medium-high heat until the oil is shimmering.
Place the salmon in the pan skin-side down and press gently with a spatula for 10 seconds to prevent curling.
Sear the salmon for 4 to 5 minutes without moving it until the skin is golden and crispy.
Carefully flip the fillet and cook for another 2 to 3 minutes until the salmon is just opaque and flakes easily with a fork.
Plate the salmon alongside the roasted asparagus and finish with a generous squeeze of fresh lemon juice over everything.
