Instructions
- Step 1: Preheat oven to 400°F. Line a baking sheet with parchment paper. Toss 1 lb trimmed asparagus with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper. Spread asparagus evenly on one side of the baking sheet.
- Step 2: Place 4 cod fillets on the other side of the baking sheet. Season fillets with 1/2 tsp salt and 1/4 tsp black pepper.
- Step 3: In a small bowl, mix 4 tbsp melted unsalted butter, 2 tbsp fresh lemon juice, 2 tbsp drained capers, and 3 minced garlic cloves.
- Step 4: Spoon the lemon-caper butter evenly over the cod fillets, reserving a small amount for drizzling over asparagus after baking.
- Step 5: Bake for 12-15 minutes until cod is opaque and flakes easily with a fork, and asparagus is tender-crisp.
- Step 6: Remove from oven and drizzle remaining lemon-caper butter over roasted asparagus. Garnish cod and asparagus with 2 tbsp chopped fresh parsley before serving.
