Air Fryer Catfish
If you’re craving that crispy, golden catfish without turning on the stove or dealing with oil splatters, try this Air Fryer Catfish. It’s flaky and tender on the inside with a spiced cornmeal crust that delivers serious crunch—just like your favorite Southern-style fried catfish, but lighter and way less messy.
This one is a regular in my dinner rotation. We try to eat fish once a week, and catfish is one of those budget-friendly, protein-packed options I always come back to. I love how quick it is to cook, and the air fryer gives you that deep-fried texture without the grease or fishy smell taking over your kitchen.
Whether you’re cooking for a crowd, observing a meatless Friday, or just need a quick 30-minute dinner, this catfish is what you’re looking for. A little Cajun seasoning, a squeeze of lemon, and you’re good to go.
If you’re into bold flavors, definitely check out my Air Fryer Blackened Tilapia—another fast favorite that’s full of smoky, spicy flavor. Or try Air Fryer Mahi Mahi for something a little lighter but still flaky and delicious. Once you realize how easy fish can be in the air fryer, you’ll want to try them all.

How to Make Catfish in the Air Fryer
- Preheat your air fryer to 400°F. Pat the catfish fillets dry and drizzle with melted butter, coating all sides.
- Mix the coating by combining cornmeal, Cajun seasoning, salt, and pepper in a shallow dish. Dredge each fillet in the mixture, pressing to coat both sides.
- Spray the air fryer basket and place the fillets in a single layer with space in between. Lightly spray the tops with oil.
- Air fry for 14 minutes, flipping halfway. Add an extra 3–4 minutes if needed, until the crust is golden and the fish flakes easily.
- Serve hot with lemon wedges and your favorite sides.
Tips for Crispy Air Fryer Catfish
✔️ Don’t overcrowd the basket. The hot air needs space to circulate. Cook in batches if needed.
✔️ Dry the fish well. Excess moisture = soggy crust. Pat it dry before seasoning.
✔️ Use a thin spatula. Catfish is delicate—flipping with care helps keep that crispy coating intact.
✔️ Too fishy? Soak the fillets in milk for 30 minutes before cooking to mellow the flavor.
✔️ Adjust seasoning to your taste. Spicier, saltier, or more herb-forward—it’s your dinner, your call.

What to Serve with Air Fryer Catfish
This crispy catfish is super versatile, so you can pair it with whatever you’re in the mood for. I love serving it with steamed rice or mashed potatoes for a classic combo, or balancing it out with lighter sides like air fryer broccoli or asparagus. If you’re leaning into comfort food, go all in with a scoop of Instant Pot mac and cheese or cheesy air fryer garlic bread. And don’t forget the lemon wedges—a fresh squeeze of citrus really brings it all together.
How to Store & Reheat
Fridge: Store leftover catfish in an airtight container for up to 3 days.
Reheat: Pop it back into the air fryer at 350°F for 5–6 minutes, or until hot and crispy again.
Freezer: Freeze cooked fillets for up to 1 month. Reheat straight from frozen in the air fryer—just add a few extra minutes.
