Prep the fish. Pat the cod very dry with paper towels. Cut into bite-sized pieces, about 1 to 1.5 inches. Dry fish equals crispier bites.

Set up a breading station. In one shallow bowl, add flour with a pinch of salt and pepper. In a second, beat the eggs. In a third, mix panko, garlic powder, onion powder, paprika, remaining salt and pepper, and optional Parmesan or parsley.

Coat the bites. Toss the cod pieces in flour, shaking off excess. Dip in egg, then press into the panko mix to fully coat. Place on a plate as you go.

Add a little oil. Drizzle or lightly brush the coated bites with the olive oil, or mist with oil spray. This helps with browning.

Preheat the air fryer. Set to 400°F (200°C) for 3 minutes. Lightly spray the basket to prevent sticking.

Air fry in batches. Arrange cod bites in a single layer with a bit of space. Cook for 6 to 8 minutes, flipping halfway. They’re done when the coating is golden and the fish flakes easily. Thicker pieces may need up to 9 minutes; don’t overcook.

Season and serve. Sprinkle with a little extra salt while hot. Squeeze fresh lemon over the top and serve with your favorite sauce.
