Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and toss the spears with 1 teaspoon of olive oil, 0.25 teaspoon of sea salt, and a pinch of black pepper.
Spread the asparagus in a single layer on the baking sheet and roast for 12-15 minutes until 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 1 teaspoon of olive oil in a non-stick or cast-iron skillet over medium-high heat.
Place the salmon in the pan, skin-side down, and press gently with a spatula for 10 seconds to ensure even contact; sear for 4-5 minutes until the skin is very crispy.
Carefully flip the salmon and cook for another 2-3 minutes, adding the minced garlic to the pan during the last minute of cooking to aromaticize the oil.
Remove from heat and plate the salmon alongside the roasted asparagus, drizzling everything with fresh lemon juice before serving.
