Ingredients
  

  • 1 to 1.5 pounds cod fillets, about 4 pieces (skinless, 1-inch thick if possible)
  • 1/2 cup grated Parmesan cheese (freshly grated if you can)
  • 1/3 cup plain breadcrumbs or panko
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon smoked paprika (or sweet paprika)
  • 1/4 teaspoon dried thyme or Italian seasoning
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1/4 teaspoon black pepper
  • 2 tablespoons mayonnaise or Greek yogurt
  • 1 tablespoon Dijon mustard (or a mild mustard)
  • 1 tablespoon lemon juice, plus lemon wedges for serving
  • Olive oil spray or a light brush of olive oil
  • Fresh parsley, chopped (optional, for garnish)

Method
 

  1. Prep the air fryer: Preheat your air fryer to 390°F (200°C) for 3–5 minutes. A hot basket helps the crust crisp up.
  2. Pat the cod dry: Use paper towels to remove as much surface moisture as you can. Dry fish = better crust.
  3. Mix the wet coating: In a small bowl, stir together the mayonnaise, Dijon mustard, and lemon juice. This helps the crumb mixture stick and adds tang.
  4. Make the crust: In another bowl, combine Parmesan, breadcrumbs, garlic powder, onion powder, paprika, thyme, salt, and pepper. Stir to blend evenly.
  5. Assemble the fillets: Brush or spread the mustard-mayo mixture over the top and sides of each piece of cod. Press the Parmesan breadcrumb mixture onto the coated fish, packing it gently so it adheres.
  6. Prep the basket: Lightly spray the air fryer basket with olive oil or brush with a thin layer. This keeps the crust from sticking.
  7. Cook: Arrange the fillets in a single layer with a little space between each. Air fry for 8–10 minutes for 1-inch thick fillets, or until the crust is golden and the fish flakes easily. Thinner pieces may need 6–7 minutes; thicker pieces may need up to 12.
  8. Check doneness: The fish should flake with a fork and be opaque throughout. For accuracy, use a thermometer—internal temp should reach 145°F (63°C) at the thickest point.
  9. Finish and serve: Squeeze fresh lemon over the top, sprinkle with parsley, and serve right away. Good sides include roasted potatoes, a green salad, or steamed asparagus.
