Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 3 tbsp lemon juice, 3 minced garlic cloves, 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper.
  2. Step 2: Place 4 cod fillets in a baking dish and brush evenly with the lemon-garlic marinade. Let marinate at room temperature for 10 minutes.
  3. Step 3: On a large baking sheet, toss 2 sliced zucchini, 1 large chopped red bell pepper, and 2 sliced carrots with 2 tbsp olive oil, 1/2 tsp salt, 1/4 tsp black pepper, and 1 tsp dried oregano. Spread in an even layer.
  4. Step 4: Roast vegetables in the oven for 20 minutes. After 10 minutes, place the marinated cod fillets on a separate baking sheet and bake both cod and vegetables for the remaining 10 minutes until cod is opaque and flakes easily.
  5. Step 5: While baking, prepare herb pesto by blending 1 cup fresh basil, 1/2 cup fresh parsley, 1/4 cup toasted pine nuts, 1/4 cup grated Parmesan, and 2 tbsp olive oil until smooth.
  6. Step 6: Serve baked cod topped with 2 tbsp herb pesto per fillet, alongside the roasted vegetables for a bright, flavorful meal.
