01 - Preheat oven to 400°F. Line a large rimmed baking sheet with parchment paper or foil for easy cleanup.
02 - In a small bowl, whisk together olive oil, lemon juice, lemon zest, garlic, oregano, thyme, salt, and pepper until well combined.
03 - Arrange asparagus and cherry tomatoes on the prepared baking sheet. Drizzle with half the marinade and toss to coat evenly. Spread vegetables in a single layer, leaving space for salmon.
04 - Place salmon fillets on the baking sheet. Brush tops with remaining marinade, ensuring each fillet is evenly coated.
05 - Roast for 15-18 minutes until salmon is opaque and flakes easily with a fork, and vegetables are tender-crisp.
06 - Remove from oven, sprinkle with fresh parsley, and serve immediately with lemon wedges on the side.
