Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Trim the tough, woody ends off the asparagus spears and place them on one side of the prepared baking sheet.
Pat the salmon fillet completely dry with a paper towel and place it on the other side of the baking sheet.
In a small bowl, combine 1 teaspoon of olive oil with the finely chopped parsley, dill, garlic powder, and lemon zest to create a paste.
Drizzle the remaining teaspoon of olive oil over the asparagus and toss to coat evenly.
Spread the herb paste over the top of the salmon fillet, pressing down gently so the crust adheres to the fish.
Sprinkle the sea salt and black pepper evenly over both the salmon and the asparagus.
Roast in the center of the oven for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork.
Remove from the oven and serve immediately with a fresh lemon wedge for squeezing over the top.
