Preparation: Begin by patting the cod fillets dry using a paper towel. This ensures proper seasoning adhesion and optimal cooking.

Seasoning Mixture: In a small bowl, combine the lemon zest, freshly squeezed lemon juice, coarsely ground black pepper, a drizzle of olive oil, garlic powder (if using), and salt. Mix well to form a consistent seasoning paste.

Marinate: Brush or rub the seasoning mixture generously over both sides of the cod fillets. Let the fillets marinate for about 10-15 minutes to soak in the flavors.

Preheat Air Fryer: Set your air fryer to 375°F (190°C) and allow it to preheat for a few minutes.

Cooking: Once preheated, place the marinated cod fillets in the air fryer basket, ensuring they are not overlapping. Cook for 10-12 minutes, flipping halfway through. The exact time might vary based on the thickness of the fillets and the air fryer model, so keep an eye on them.

Check Doneness: The cod is ready when it easily flakes with a fork and has a translucent-to-opaque color. If unsure, you can use a meat thermometer – the internal temperature should read 145°F (63°C).

Serving: Once cooked, transfer the cod fillets to a serving plate. Drizzle any remaining lemon-pepper mixture or a squeeze of fresh lemon juice over the top. Garnish with freshly chopped parsley for an added touch of freshness.

Enjoy: Serve your Lemon Pepper Cod hot with your choice of sides. Some popular options include a light salad, steamed veggies, or a grain like quinoa or rice.
