01 - Preheat oven to 400°F. Line a large sheet pan with parchment paper or lightly grease it.
02 - In a small bowl, whisk together olive oil, lemon juice, lemon zest, garlic, parsley, thyme, oregano, salt, and black pepper.
03 - Place the salmon fillets on one side of the prepared sheet pan and the asparagus on the other.
04 - Drizzle half of the marinade over the salmon and the other half over the asparagus. Toss asparagus to coat evenly.
05 - Arrange everything in a single layer for even cooking.
06 - Roast in the oven for 15–18 minutes, or until the salmon is opaque and flakes easily with a fork, and the asparagus is tender.
07 - Serve immediately with lemon wedges and additional herbs, if desired.
