Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Toss 1 lb trimmed asparagus spears with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread on a rimmed baking sheet and roast for 15 minutes until tender and slightly caramelized.
  2. Step 2: While asparagus roasts, place 4 cod fillets (6 oz each) on a parchment-lined baking tray. Drizzle 2 tbsp olive oil over the fillets and season with 1/2 tsp salt and 1/4 tsp black pepper.
  3. Step 3: Bake the cod for 12-15 minutes until the fish flakes easily with a fork.
  4. Step 4: In a small bowl, combine 3 tbsp fresh lemon juice, 2 tbsp drained capers, 2 minced garlic cloves, 2 tbsp chopped fresh parsley, and 2 tbsp olive oil. Stir to make the lemon-caper sauce.
  5. Step 5: Serve each cod fillet topped generously with the lemon-caper sauce alongside the roasted asparagus spears.
