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