Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Lightly oil a baking dish with 1 tbsp olive oil. Pat dry 4 cod fillets and season both sides with 1 tsp salt and 1/2 tsp black pepper. Place fillets in the baking dish.
  2. Step 2: In a small bowl, whisk together 3 tbsp lemon juice, 2 tbsp olive oil, 2 tbsp drained capers, 1/2 tsp salt, and 1/2 tsp black pepper. Pour this lemon-caper sauce evenly over the cod fillets.
  3. Step 3: Bake the cod for 12-15 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: While the fish bakes, heat 1 tbsp olive oil in a large skillet over medium heat. Add 4 thinly sliced garlic cloves and sauté for 1-2 minutes until fragrant but not browned.
  5. Step 5: Add 8 cups baby spinach leaves and 2 tbsp white wine (if using). Cook, stirring frequently, for 3-4 minutes until the spinach is fully wilted. Season with 1/2 tsp salt and 1/2 tsp black pepper.
  6. Step 6: Plate the baked cod fillets topped with the lemon-caper sauce alongside the garlic wilted spinach. Sprinkle 2 tbsp chopped fresh parsley over the fish before serving.
