Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus and place the spears on the baking sheet.
Drizzle half of the olive oil over the asparagus, add the minced garlic, and season with a pinch of sea salt and black pepper.
Roast the asparagus for 12 to 15 minutes until they are 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 and pepper.
Heat the remaining olive oil in a stainless steel or cast-iron skillet over medium-high heat until shimmering.
Place the salmon in the pan skin-side down and press gently with a spatula for 10 seconds to ensure even contact.
Sear for 4 to 5 minutes without moving it until the skin is golden and crispy, then flip and cook for another 2 to 3 minutes.
Remove from heat and squeeze the fresh lemon juice over the salmon and asparagus before serving.
