Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 3 tbsp lemon juice, 4 tbsp olive oil, 1 1/2 tsp dried oregano, 3 minced garlic cloves, 1 tsp salt, and 3/4 tsp black pepper.
  2. Step 2: Arrange 4 cod fillets in a baking dish. Pour half of the lemon-oregano mixture over fish, coating evenly.
  3. Step 3: In a separate bowl, toss 1 sliced zucchini, 1 chopped red bell pepper, 1 wedged red onion, and 1 cup cherry tomatoes with remaining lemon-oregano mixture.
  4. Step 4: Spread vegetables around the cod fillets in the baking dish. Bake uncovered for 18-20 minutes until fish is opaque and flakes easily with a fork.
  5. Step 5: Garnish with 2 tbsp chopped fresh parsley before serving warm.
