When I want something crunchy without the mess and greasiness of deep frying, I make these Air Fryer Crispy Fish fillets. They develop an irresistibly crisp exterior while the inside remains tender and flaky. Using the air fryer keeps things clean and simple—no splattering oil—and dinner is ready in about 20 minutes.
This recipe balances texture and flavor so well that it quickly became a household favorite. These fillets work great on sandwiches, over rice, or as a lighter take on classic fish and chips. I also serve them with veggie chips or air-fried zucchini fries to make the meal more balanced for the kids.

Biting into a crunchy, well-seasoned piece of fish is so satisfying. These fillets are seasoned with Cajun spices, coated in a lemon-mayo wash, and dredged in cornmeal for extra crunch. The golden air-fried crust appeals even to picky eaters, and I feel good serving this to my family.
Why you will love this recipe
- No oil required: The air fryer produces crisp, tasty fillets without deep frying, making this a lighter option that still delivers texture and flavor.
- Quick and simple: With a handful of ingredients and straightforward steps, you can have these fillets ready in under 30 minutes.
- Less cleanup: Skip the deep fryer and the greasy cleanup—this method keeps your kitchen tidy while still giving you the fried texture you crave.
- Versatile with different fish: Any mild white fish works well. I usually use cod, but haddock, tilapia, or mahi-mahi are all good choices.
What you will need
- Fish: About 1½ lbs. of white fish fillets roughly 1/2-inch thick (cod is my go-to).
- Wet mix: Mayonnaise and fresh lemon juice—this binds the coating and keeps the fish moist while adding bright flavor.
- Dry mix: A blend of all-purpose flour and cornmeal for structure and crunch, seasoned with Cajun seasoning, smoked paprika, garlic powder, salt, and pepper.
How to make
Mix the dry ingredients: Pat the fillets dry, then whisk cornmeal, flour, Cajun seasoning, smoked paprika, garlic powder, salt, and pepper in a shallow bowl.
Mix the wet ingredients: Whisk mayonnaise and lemon juice in a separate bowl. Coat each fillet in this mixture so it’s evenly covered but not thickly frosted.
Coat the fish: Dredge each fillet in the flour-cornmeal mix, pressing gently so the coating adheres. Shake off any excess.
Air fry: Place fillets in a single layer in the air fryer basket with space between each piece. Air fry at 400°F for 8–10 minutes, flipping after about 5 minutes, until golden and crisp. Work in batches if needed.
Expert tip
What kind of fish is best?
Choose a mild white fish about 1/2-inch thick that holds together when coated. Cod and haddock are excellent choices because they’re firm and flaky without falling apart. Tilapia, trout, flounder, and mahi-mahi also work well depending on your preference.
More tips to consider:
- Use fillets of similar thickness so they cook evenly.
- Don’t overcrowd the basket—crowding causes steaming instead of crisping.
- Pat fillets dry before coating to help the coating stick.
- Shake off excess breading before air frying for an even crust.
- Thin fillets (about 1/4 inch) take 6–8 minutes; thicker fillets may need 10–12 minutes.
Recipe variations and add-ins:
- Spicy: Add cayenne pepper or red pepper flakes to the dry mix for heat.
- Crack-style: Mix crushed bacon, ranch seasoning, and shredded cheddar into the coating for an indulgent crust.
- Beer batter: Substitute the lemon juice in the wet mix with beer for a light, beer-battered flavor.
- Cheesy crust: Stir grated Parmesan into the dry mix for a savory, cheesy finish—reduce added salt if you do.
Serving suggestions:
These fillets pair beautifully with air fryer potato chips, crispy potato wedges, or buttered boiled potatoes. For a classic plate, serve with coleslaw and lemon wedges. They also make excellent sandwiches topped with tartar sauce or tzatziki and go well alongside macaroni salad or baked beans for a heartier meal.
How to store leftovers:
- Refrigerate: Store cooled leftovers in an airtight container in the refrigerator for up to 4 days.
- Freeze: Flash-freeze in a single layer on a baking sheet, then transfer to freezer bags; keep up to 4 months.
- Thaw: Thaw overnight in the refrigerator for best texture.
- Reheat: Reheat in the air fryer at 350°F for 3–5 minutes to restore crispiness.
Frequently asked questions
Avoid overcrowding the basket so air can circulate properly. If sticking persists, try reusable air-fryer parchment liners or a light nonstick spray designed for air fryers. Also check the condition of your basket’s nonstick coating.
Yes—just thaw the fish completely and pat it dry before coating. Thawed fillets will coat and cook similarly to fresh ones.
If pieces are too close together they steam instead of crisping. Cook in single layers with space between pieces and in batches if necessary to ensure even airflow and browning.
Dry the fillets well, apply a thin even layer of the mayo-lemon mixture, press the fillets into the cornmeal mix, and let them rest 10–15 minutes before cooking to help the coating adhere and crisp.
