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 them on the baking sheet with 1 tsp of olive oil, a pinch of sea salt, and black pepper.
Roast the asparagus for 10-12 minutes until tender and slightly charred at the tips.
While the asparagus roasts, pat the salmon fillet completely dry with paper towels to ensure a crispy sear.
Season both sides of the salmon with the remaining sea salt, black pepper, and garlic powder.
Heat a heavy-bottomed skillet over medium-high heat and add the remaining 1.5 tsp of olive oil.
Once the oil is shimmering, place the salmon skin-side down in the pan and press gently with a spatula for 30 seconds.
Sear undisturbed for 4-5 minutes until the skin is golden and releases easily from the pan.
Flip the salmon and cook for an additional 2-3 minutes until the internal temperature reaches 125-130°F for a perfect medium-rare.
Remove the salmon from the pan and let it rest for 2 minutes before serving with the roasted asparagus and a fresh squeeze of lemon juice.
