Ingredients
Scale
For the Chips
- 3 russet potatoes (about 1½ pounds), peeled and cut into ½-inch thick slices
- 1 teaspoon salt
- 1 teaspoon freshly ground black pepper
For the Fish
- 1½ cups all-purpose flour, divided
- ¼ cup cornstarch
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- ½ teaspoon salt
- ½ teaspoon freshly ground black pepper
- ½ teaspoon baking soda
- 8–10 ounces beer (light lager works best)
- 1 pound cod fish fillets (about 5 pieces), patted very dry with paper towels
Instructions
Prepare the Chips
- Soak the cut potatoes in cold water for at least 30 minutes (up to 3 hours for extra crispiness). If soaking longer than 30 minutes, change the water once.
- Drain the potatoes and dry them completely with a clean towel – this step is crucial for crispy chips.
- Spray your air fryer basket generously with cooking oil. Add the potatoes and spray the tops with more oil.
- Air fry at 400°F for 7 minutes, then toss and cook another 7 minutes until golden and crispy.
- Season with salt and pepper, then transfer to a serving dish and cover with foil to keep warm.
Prepare the Fish
- In a shallow bowl, whisk together ½ cup flour and all the cornstarch.
- In a large bowl, combine the remaining 1 cup flour, garlic powder, onion powder, salt, pepper, and baking soda. Pour in the beer and whisk until smooth.
- Dredge each fish piece in the flour mixture first, then dip into the beer batter, letting excess drip off.
- Roll the battered fish back in the flour mixture until completely coated, shaking off excess.
- Line your air fryer basket with parchment paper and spray generously with oil.
- Place the coated fish in the basket – they can touch but shouldn’t overlap.
- Spray the fish tops thoroughly with oil, then air fry at 390°F for 12 minutes, spraying again halfway through.
Notes
- Pat the fish completely dry before coating – moisture is the enemy of crispy batter .
- Don’t skip soaking the potatoes – it removes excess starch for crispier chips.
- Use parchment paper in the basket to prevent sticking.
- Spray generously with oil at every step – this replaces the oil from deep frying .
- Cook in batches if needed rather than overcrowding the basket • Let the beer batter rest for 5 minutes before using for better texture .
- Choose similar-sized fish pieces for even cooking .
- Keep the first batch warm in a 200°F oven while cooking the rest.
