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 place the spears on the baking sheet.
Drizzle the asparagus with 0.5 tbsp of olive oil and sprinkle with half of the sea salt and black pepper; toss to coat evenly.
Roast the asparagus in the oven for 12-15 minutes until they are tender and slightly charred at the tips.
While the asparagus roasts, pat the salmon fillet dry with a paper towel and season both sides with garlic powder, smoked paprika, and the remaining salt and pepper.
Heat the remaining 0.5 tbsp of olive oil in a non-stick skillet over medium-high heat.
Place the salmon in the hot pan, skin-side down, and sear for 4-5 minutes until the skin is golden and crispy.
Carefully flip the fillet and cook for another 2-3 minutes until the salmon is cooked through to your preference.
Plate the salmon alongside the roasted asparagus and finish with a fresh squeeze of lemon juice over everything.
