Fish tacos should be crispy. They should be creamy. They should make you close your eyes and say “yep.”
These are all three. Beer-battered cod. Crunchy slaw. Zesty lime sauce. All wrapped in a warm tortilla. 30 minutes. Let’s go.

Storage Notes
Best Fresh:
Fish tacos are best hot and crispy. Leftovers get soggy.
Reheat Fish:
Air fryer at 375°F for 4-5 minutes. Oven at 400°F for 8 minutes. Never microwave.
Pro Tip:
Cold beer = lighter, crispier batter. Use lager or pilsner. Don’t use light beer.
