1. Prepare the Cod: Start by patting the cod fillets thoroughly dry with paper towels. This is a crucial step for achieving crispy results. Once dry, cut the cod into 1-inch bite-sized pieces or “nuggets.” Aim for uniform sizes so they cook evenly.

2. Season the Cod: In a medium bowl, combine the olive oil and minced garlic. Add the cod pieces to the bowl and gently toss to coat them evenly with the garlicky oil.

3. Create the Coating Mixture: In a separate shallow dish or bowl, mix together the grated Parmesan cheese, breadcrumbs, dried parsley, onion powder, salt, and black pepper. Stir well to ensure all the spices are evenly distributed.

4. Coat the Cod Nuggets: Take each oil-coated cod piece and dredge it in the breadcrumb mixture, pressing gently to ensure a good coating on all sides. Place the coated nuggets on a plate as you work.

5. Preheat and Arrange in Air Fryer: Preheat your air fryer to 375 F (190 C) for about 3-5 minutes. Once preheated, lightly spray the air fryer basket with cooking spray or brush with a little oil to prevent sticking. Arrange the coated cod nuggets in a single layer in the air fryer basket, making sure not to overcrowd it. You may need to cook them in batches.

6. Air Fry Until Golden and Cooked Through: Air fry the cod nuggets for 6-8 minutes, then flip them gently with tongs. Continue to air fry for another 6-7 minutes, or until the cod is opaque throughout, flakes easily with a fork, and the coating is golden brown and crispy.

7. Serve Immediately: Remove the cooked cod nuggets from the air fryer and serve them hot with fresh lemon wedges for a bright, zesty finish.
