recipe overview
You’ll be dreaming of Louisiana with this fried catfish! A quick buttermilk and hot sauce marinade before dredging it in crunchy yellow cornmeal gives you the perfect flaky catfish. Yum!
Making fish in the air fryer is one of the best ways to get crispy on the outside, and flaky on the inside fish every time.
You get perfectly crunchy fish fry filets every time with no lingering smell of burnt oil.
list of ingredients
- Catfish filets: You can use fresh or frozen catfish for this recipe. Be sure you dry the filets well before dredging them in cornmeal.
- Buttermilk: This tangy marinade makes the best fried fish and fried chicken, too. You can make your own buttermilk with a little vinegar and regular milk.
- Hot sauce: I use a little hot sauce in my catfish marinade to get a gentle spice! It also helps marinate the fish before breading it.
- Yellow cornmeal: The best catfish is coated in crunchy cornmeal for the ultimate crust.
- Flour: You need a little flour to help the cornmeal stick to the fish. It also helps make a super crunchy crust on the catfish!
- Cajun seasoning: I love blackened catfish, and Cajun seasoning brings a great punch to this fish dish!
- Black pepper: The pungent flavor of freshly cracked pepper is perfect in this catfish crust. It brings just enough heat to the palate without overwhelming it.

why you need to soak catfish
Catfish is known for living on the bottom of rivers, and it can taste just like the mud it hunts in.
To get rid of that potentially muddy taste, I soak mine in buttermilk for at least 20 minutes before breading the filets! Some recipes call to marinate it overnight, but I think half an hour is plenty of time for this Air Fryer Catfish recipe.
You can also use beer or plain milk in a pinch. Or, just make your own buttermilk with a little milk and white vinegar. It’s that easy!
how to make air fryer catfish
- Whisk the buttermilk and hot sauce together for a quick marinade. I use gallon-sized baggies to cut down on dirty dishes. Cover the fish completely in the marinade and chill.
- While the fish marinates, whisk together the flour, yellow cornmeal, cajun seasoning, and pepper.
- When it’s time to cook, let the fish drain off any extra marinade in a colander.
- Dredge the filets in the cornmeal mixture on all sides. Press the filets gently into the dry ingredients to help coat the fish. Let it rest a few minutes on a plate or baking sheet before air frying.
- Place one layer of breaded filets in the air fryer and spray lightly with oil.
- Air fry the catfish filets at 375 degrees F for 10 minutes, then flip, spray again, and cook another 7 to 10 more minutes. Serve with tartar sauce and lemon wedges.

There’s no better Southern side dish than creamy grits! You only need 4 ingredients for this dairy-free option.
Keep it simple with a crunchy frozen side everyone loves — onion rings! No one will mind that it’s fried on fried. Trust me.
