Preheat your oven to 400°F (200°C) and line a 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 0.5 tsp of olive oil and sprinkle with half of the sea salt and black pepper.
Roast the asparagus in the oven for 10-12 minutes until they are tender and slightly charred.
While the asparagus roasts, pat the salmon fillet dry with a paper towel and season both sides with garlic powder, dried dill, and the remaining salt and pepper.
Heat the remaining 1 tsp of olive oil in a medium non-stick skillet over medium-high heat until shimmering.
Place the salmon in the pan, skin-side down, and press gently with a spatula to ensure even contact; sear for 4-5 minutes until the skin is golden and crispy.
Carefully flip the salmon and cook for an additional 3-4 minutes, or until the fish is opaque and flakes easily with a fork.
Plate the salmon alongside the roasted asparagus and finish with a fresh squeeze of lemon juice over the entire dish.
