Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Wash the asparagus and trim the tough, woody ends off the bottom of the spears.
Place the asparagus on the baking sheet and drizzle with half of the olive oil, half of the sea salt, and half of the black pepper.
Roast the asparagus in the oven for 10 to 12 minutes until they are tender and slightly charred at the tips.
While the asparagus roasts, pat the salmon fillet completely dry with a paper towel and season with the remaining salt, pepper, and garlic powder.
Heat the remaining olive oil in a non-stick skillet over medium-high heat until shimmering.
Place the salmon in the pan skin-side down and sear for 4 to 5 minutes without moving it to ensure a crispy crust.
Carefully flip the salmon and cook for another 2 to 3 minutes until the fish is opaque and flakes easily with a fork.
Plate the salmon next to the roasted asparagus and finish with a fresh squeeze of lemon juice over the entire dish.
