Instructions

Step 1: Preheat oven to 400°F. Place 4 cod fillets on a baking sheet lined with parchment paper. Drizzle 2 tablespoons olive oil evenly over the fillets and season with 1 teaspoon salt and 1/2 teaspoon black pepper.
Step 2: Roast cod in the oven for 12-15 minutes until opaque and flakes easily with a fork.
Step 3: While cod roasts, melt 4 tablespoons unsalted butter in a small saucepan over low heat. Add 2 minced garlic cloves and sauté for 1 minute until fragrant.
Step 4: Remove butter from heat and stir in 1/4 cup chopped fresh parsley, 1 teaspoon lemon zest, and 2 tablespoons lemon juice.
Step 5: Spoon the warm lemon parsley butter over the roasted cod fillets before serving for a fresh and buttery finish.
