📝 About This Recipe

Experience the ultimate British pub classic reimagined for the modern kitchen with this incredibly crispy air-fried beer battered cod. By using a chilled carbonated batter and a clever 'pre-set' technique, we achieve that iconic shattered-glass crunch without the heavy grease of deep-frying. The result is succulent, flaky white fish encased in a light, golden shell that sings with the subtle malty notes of your favorite lager.

🥗 Ingredients

The Fish

  • 1.5 pounds Fresh Cod Fillets (cut into 4-inch batons and patted very dry)
  • 1 teaspoon Salt (kosher or sea salt)
  • 1/2 teaspoon Black Pepper (freshly cracked)

The Dry Dredge

  • 1/2 cup All-purpose Flour (for the initial coating)
  • 1/2 teaspoon Garlic Powder
  • 1 teaspoon Old Bay Seasoning (or smoked paprika)

The Beer Batter

  • 1 cup All-purpose Flour (chilled in the freezer for 10 minutes)
  • 1/4 cup Cornstarch (essential for extra crispiness)
  • 1 teaspoon Baking Powder (creates air pockets in the crust)
  • 1 cup Cold Lager or Pale Ale (very cold, straight from the fridge)
  • 2 tablespoons Vegetable Oil (mixed into the batter for browning)

Finishing

  • 1 bottle Cooking Oil Spray (high smoke point like avocado or canola oil)
  • 4 pieces Lemon Wedges (for serving)
  • 1 tablespoon Fresh Parsley (finely chopped for garnish)

👨‍🍳 Instructions

  1. 1

    Pat the cod fillets thoroughly dry with paper towels. Moisture is the enemy of crispiness; moisture creates steam which will make the batter soggy.

  2. 2

    Season the fish pieces on all sides with salt and black pepper. Let them sit for 5 minutes, then pat dry one more time to remove any moisture drawn out by the salt.

  3. 3

    Preheat your air fryer to 400°F (200°C) for at least 5 minutes. A hot basket is crucial to prevent sticking.

  4. 4

    In a shallow bowl, whisk together the 'Dry Dredge' ingredients: 1/2 cup flour, garlic powder, and Old Bay seasoning.

  5. 5

    In a separate medium bowl, whisk the 'Beer Batter' dry ingredients: 1 cup chilled flour, cornstarch, and baking powder.

  6. 6

    Slowly pour the ice-cold beer and 2 tablespoons of oil into the dry batter mix. Whisk gently until just combined; a few small lumps are perfectly fine. Do not overmix, or you'll lose the carbonation.

  7. 7

    Cut a piece of parchment paper to fit your air fryer basket and poke several holes in it to allow air circulation. Do not place the paper in the fryer yet.

  8. 8

    Dredge a piece of fish in the seasoned flour, shaking off all excess. It should be a very thin, even coating.

  9. 9

    Dip the floured fish into the beer batter, ensuring it is fully submerged and coated. Lift and let the excess batter drip off for 5 seconds.

  10. 10

    Place the battered fish onto the prepared parchment paper. Repeat with remaining pieces, ensuring they do not touch.

  11. 11

    Generously spray the tops of the battered fish with the cooking oil spray. This helps the batter 'set' and brown in the air fryer.

  12. 12

    Carefully place the parchment with the fish into the preheated air fryer basket. Cook at 400°F for 8 minutes.

  13. 13

    Gently flip the fish using a thin spatula. Spray the other side with oil and cook for an additional 4-7 minutes, or until the coating is deep golden brown and the internal temperature of the fish reaches 145°F.

  14. 14

    Remove the fish and let it rest on a wire rack for 2 minutes. This allows the steam to escape without softening the bottom crust.

  15. 15

    Garnish with fresh parsley and serve immediately with lemon wedges.

💡 Chef's Tips

Always use ice-cold beer; the temperature difference between the cold batter and the hot air fryer creates the crispest texture. Avoid over-crowding the basket; if the pieces touch, the batter will merge and become gummy. If your batter seems too thin, add a tablespoon of flour at a time; it should be thick enough to coat a finger without being doughy. For the best results, use a high-quality spray oil rather than an aerosol with additives, which can damage air fryer coatings and affect flavor.

🍽️ Serving Suggestions

Serve with thick-cut steak fries (chips) and a side of mushy peas for a traditional experience. Pair with a cold, crisp Pilsner or a zesty Sauvignon Blanc to cut through the richness. Provide a side of homemade tartar sauce with extra capers and fresh dill. A splash of malt vinegar over the hot fish is the secret to authentic British flavor.
