Soak catfish in buttermilk for 15 minutes.
Mix cornmeal, flour, Cajun seasoning, garlic powder, salt, and pepper.
Remove catfish from buttermilk, letting excess drip off. Press into cornmeal mixture, coating all sides.
Spray generously with cooking spray.
Air fry at 400°F for 10-12 minutes, flipping halfway, until crust is golden and fish flakes. Serve with hot sauce, lemon, coleslaw, and tartar sauce.
Tip: The buttermilk soak tenderizes the fish and helps the coating stick. Cornmeal gives authentic Southern crunch — don't substitute breadcrumbs. Catfish has a mild, slightly sweet flavor that pairs perfectly with Cajun spice and hot sauce.
