Instructions

  1. Step 1: Preheat oven to 400°F. On a large rimmed baking sheet, toss 1 lb trimmed asparagus spears with 1 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper. Spread in a single layer.
  2. Step 2: Place 4 salmon fillets (6 oz each) skin-side down on the baking sheet next to the asparagus. Drizzle salmon with remaining 2 tbsp olive oil, 3 minced garlic cloves, zest and juice of 1 large lemon, 1 tsp sea salt, and 3/4 tsp black pepper.
  3. Step 3: Roast in the oven for 12-15 minutes until salmon flakes easily with a fork and asparagus is tender-crisp.
  4. Step 4: Remove from oven and sprinkle 2 tbsp chopped fresh parsley over salmon and asparagus before serving.
