Step 1

Scrub the potatoes well (there is no need to peel them). Cut the potatoes in half lengthwise, then turn the halves onto their flat sides, and cut them into ¼-inch-thick planks. Cut each plank into ¼-inch-thick sticks.

Step 2

Place the potatoes in a bowl of cold water and soak for 10 minutes to remove excess starch. Drain the potatoes, then return them to the bowl and refill with cold water. Mix with your hands to clean the potatoes of more starch, then drain well again.

Step 3

Spread them out in a single layer on a lint-free tea towel or paper towels, and pat them very dry. Wipe the same bowl dry and add the potatoes to it. Drizzle the potatoes all over with olive oil and sprinkle with salt. Toss well to combine.

Step 4

Preheat the air fryer to 325°F.

Step 5

Place the potatoes in the air fryer basket, reserving the bowl. Cook for 12 minutes.

Step 6

Remove half of the par-cooked potatoes to the reserved bowl, then spread the remaining half in the air fryer into a single layer. Cook again for 12 more minutes, shaking the basket halfway through, until golden and crispy. Immediately sprinkle the crispy fries with more salt and pepper to taste. Set aside on a cooling rack or baking sheet and keep warm.

Step 7

Repeat with the remaining half of the par-cooked potatoes.

Step 8

While the potatoes are cooking, whisk together the flour, salt, pepper, and garlic powder in a shallow dish. In a second shallow dish, beat the eggs until well combined. Place the Panko in a third shallow bowl.

Step 9

Cut the cod filets into 4 to 6 similarly sized pieces. Dredge each piece of fish by first coating it in the flour mixture, then with the egg, and lastly, coating it with the Panko.

Step 10

When the potatoes are done, reduce the air fryer temperature to 375°F.

Step 11

Spray the basket with cooking spray. Place half of the breaded fish pieces in the air fryer in a single layer, leaving a small amount of space in between each piece. Spray the fish well with cooking spray.

Step 12

Cook for 6 minutes. Flip the fish pieces and spray the other side well with cooking spray. Continue to cook for 6 more minutes, or until golden brown and the internal temperature of each piece reaches 145°F. Remove, immediately season with salt to taste, and keep the warm.

Step 13

Continue cooking the remaining fish. If desired, carefully wipe out any crumbs from the air fryer basket and reheat the fries in the air fryer for 3 minutes at 400°F. Serve the fish and chips with tartar sauce, lemon wedges, and malt vinegar.
