Ingredients

Instructions

  1. Step 1: Preheat the oven to 400°F. Line a baking sheet with parchment paper. Place 1 lb trimmed asparagus spears and 10 peeled whole garlic cloves on the sheet, drizzle with 2 tbsp olive oil, sprinkle with 1 tsp salt, and toss to coat evenly.
  2. Step 2: Roast the asparagus and garlic in the oven for 10 minutes.
  3. Step 3: Meanwhile, rub 4 (6 oz) salmon fillets with 1 tbsp lemon zest, 2 tbsp lemon juice, 1/2 tsp salt, 1/2 tsp black pepper, and place 2 fresh thyme sprigs on each fillet.
  4. Step 4: Remove the baking sheet from the oven, push asparagus and garlic to the sides, and place the salmon fillets in the center. Drizzle the salmon with the remaining 1 tbsp olive oil.
  5. Step 5: Return the baking sheet to the oven and bake for an additional 12-15 minutes, until salmon is opaque and flakes easily with a fork and asparagus is tender.
  6. Step 6: Serve the salmon alongside the roasted asparagus and garlic cloves, garnished with additional fresh thyme if desired.
