Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. In a small bowl, whisk together 2 tbsp olive oil, 3 tbsp fresh lemon juice, 1 tsp dried oregano, 1 tsp salt, and 1/4 tsp black pepper. Place 4 cod fillets in a baking dish and brush evenly with the lemon-herb mixture.
  2. Step 2: Bake cod in the preheated oven for 12-15 minutes until fish is opaque and flakes easily with a fork.
  3. Step 3: While cod bakes, heat 1 tbsp olive oil in a large skillet over medium heat. Add 2 cloves minced garlic and sauté for 30 seconds until fragrant.
  4. Step 4: Add 6 cups baby spinach, 1/2 tsp salt, and 1/4 tsp black pepper to the skillet. Cook, stirring frequently, for 3-4 minutes until spinach is wilted and tender.
  5. Step 5: Plate cod fillets over the garlic spinach, sprinkle with 2 tbsp chopped fresh parsley and 1 tsp lemon zest before serving.
