Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Wash the asparagus and snap off the woody bottom ends, then spread the spears across one side of the prepared baking sheet.
Place the salmon fillet on the other side of the baking sheet, skin-side down.
In a small glass bowl, whisk together the extra virgin olive oil, lemon juice, lemon zest, minced garlic, and finely chopped fresh dill.
Drizzle the lemon-herb mixture evenly over both the salmon and the asparagus, using a pastry brush or spoon to ensure full coverage.
Sprinkle the sea salt and freshly cracked black pepper over the entire tray.
Roast in the center of the oven for 12 to 15 minutes, or until the salmon is opaque and flakes easily with a fork and the asparagus is tender-crisp.
Serve immediately, garnishing with an extra wedge of lemon if desired.
