Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 3 tbsp lemon juice, 4 minced garlic cloves, 3 tbsp extra virgin olive oil, 1 tsp dried thyme, 1 tsp salt, and 1/2 tsp black pepper to create the marinade.
  2. Step 2: Place 4 cod fillets in a shallow baking dish and pour half of the lemon-garlic marinade over the fish, turning to coat evenly. Let it marinate for 10 minutes at room temperature.
  3. Step 3: On a large rimmed baking sheet, toss 1 medium sliced zucchini, 1 large sliced red bell pepper, 2 medium cut carrots, and 1 small cut red onion with the remaining marinade until evenly coated. Spread vegetables in a single layer.
  4. Step 4: Roast the vegetables for 20 minutes in the preheated oven, then remove the baking sheet and stir the vegetables.
  5. Step 5: Place the marinated cod fillets on the baking sheet among the vegetables and return to the oven. Bake for an additional 12-15 minutes until the fish is opaque and flakes easily with a fork and the vegetables are tender.
  6. Step 6: Garnish with 2 tbsp chopped fresh parsley before serving warm.
