Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and place them on one side of the prepared baking sheet.
Drizzle the asparagus with 1 teaspoon of olive oil and season with half of the salt and pepper, tossing to coat evenly.
Place the salmon fillet on the other side of the baking sheet.
In a small bowl, whisk together the remaining 1 teaspoon of olive oil, lemon juice, lemon zest, minced garlic, chopped dill, chopped parsley, and the remaining salt and pepper.
Spoon the herb mixture over the salmon, pressing it down gently to create a thick crust.
Bake for 12 to 15 minutes, depending on the thickness of the fillet, until the salmon flakes easily with a fork and the asparagus is tender-crisp.
Serve immediately, garnishing with extra fresh herbs if desired.
