Preheat your oven to 400°F and line a small baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus spears and place them on the baking sheet.
Drizzle the asparagus with half of the olive oil and season 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 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 the oil is shimmering.
Place the salmon skin-side down in the hot pan and press gently with a spatula for 10 seconds to ensure even contact; sear for 4 to 5 minutes until the skin is very crispy.
Carefully flip the salmon, add the minced garlic to the pan for fragrance, and cook for another 2 to 3 minutes until the salmon reaches your desired level of doneness.
Remove from heat and serve the salmon immediately alongside the roasted asparagus, finishing the entire plate with a fresh squeeze of lemon juice.
