Difficulty: Easy
The necessary ingredients (possible in all kinds of variations)
- 4 fresh catfish fillets (or frozen and thawed)

Looking for alternative options?
You can substitute the catfish with tofu steaks or thick zucchini slices for a vegan version—just coat and cook the same way. To make it gluten-free, use a gluten-free flour mix instead of all-purpose flour. Don’t have buttermilk? Stir a tablespoon of vinegar or lemon juice into almond or oat milk and let it sit for 5 minutes—it works wonders.
The steps of preparation (possible in all kinds of variations)
Let’s move into the action! Here’s how we take simple ingredients and create magic—crispy, golden, juicy catfish that might just be the best thing you’ve ever made in your air fryer.
- Pat the catfish fillets dry with paper towels and soak them in buttermilk for at least 10 minutes to tenderize and flavor the fish.
- In a wide shallow bowl, mix the cornmeal, flour, paprika, garlic powder, cayenne, salt, and black pepper.
- Preheat your air fryer to 400°F (200°C) for 3–5 minutes.
- Remove each catfish fillet from the buttermilk and dredge thoroughly in the cornmeal mixture, pressing to coat both sides evenly.
- Lightly spray both sides of the coated fillets with olive oil spray.
- Arrange the fillets in the air fryer basket in a single layer. (You may need to do this in batches.)
- Air fry at 400°F for 12–15 minutes, flipping halfway through, until golden and crispy.
- Serve immediately with lemon wedges and fresh parsley.
Other Cooking Methods:
- Oven: Bake at 425°F on a wire rack for 20 minutes, flipping halfway.
- Pan-fry: Shallow-fry in ½ inch of oil over medium heat for 3–4 minutes per side.
