Preheat your oven to 400°F (200°C) and line a small 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 olive oil and a pinch of the sea salt and black pepper, then roast for 10-12 minutes until tender.
While the asparagus roasts, pat the salmon fillet completely dry with a paper towel and season both sides with the remaining sea salt and black pepper.
Heat the remaining olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the pan skin-side down and sear for 4-5 minutes without moving it to ensure the skin becomes crispy and golden.
Carefully flip the salmon fillet and cook for another 3-4 minutes until the fish is opaque and flakes easily with a fork.
In a small bowl, whisk together the fresh lemon juice, lemon zest, and minced garlic.
Remove the salmon and asparagus from the heat, plate them together, and pour the lemon-garlic mixture over the salmon before serving.
