Prep Time: 10 minutes
Cook Time: 12 minutes
Total Time: 22 minutes
Servings: 4 people

The secret to success is the three-step breading process that ensures the coating sticks perfectly and crisps up beautifully in the air fryer.

Key Ingredients for Air Fryer Catfish Fillets

For the Catfish:

4 catfish fillets (6-8 oz each), fresh or thawed
1 cup buttermilk
1 tablespoon hot sauce (optional)

For the Breading:

1 cup yellow cornmeal
½ cup all-purpose flour
1 tablespoon Cajun seasoning
1 teaspoon garlic powder
1 teaspoon paprika
½ teaspoon black pepper
½ teaspoon salt
¼ teaspoon cayenne pepper (adjust to taste)

For Cooking:

Cooking spray or olive oil spray

For Serving:

Lemon wedges
Tartar sauce
Hot sauce
Fresh parsley for garnish

Step-by-Step Instructions

Step 1: Prepare the Buttermilk Soak
Pat the catfish fillets completely dry with paper towels. This is crucial for helping the coating adhere properly. In a shallow bowl, combine the buttermilk with hot sauce if using. Place the fillets in the buttermilk mixture, ensuring they’re fully submerged. Let them soak for at least 10 minutes or up to 2 hours in the refrigerator. The buttermilk tenderizes the fish and helps the breading stick beautifully.

Step 2: Create the Breading Station
In a wide, shallow dish, combine the cornmeal, flour, Cajun seasoning, garlic powder, paprika, black pepper, salt, and cayenne pepper. Mix everything together thoroughly with a fork or whisk until all the spices are evenly distributed. The cornmeal provides the signature crunch while the flour helps bind everything together.

Step 3: Bread the Catfish Fillets
Remove one fillet from the buttermilk, allowing excess liquid to drip off. Press the fillet firmly into the breading mixture, coating both sides generously. Use your hands to press the breading onto the fish, ensuring complete coverage with no bare spots. Shake off any excess breading and place the coated fillet on a clean plate. Repeat with remaining fillets.

Step 4: Preheat the Air Fryer
Set your air fryer to 400°F and let it preheat for 3-5 minutes. Preheating is essential for achieving that crispy exterior. While it’s heating, lightly spray the air fryer basket with cooking spray to prevent sticking.

Step 5: Arrange Fillets in the Basket
Place the breaded catfish fillets in a single layer in the air fryer basket. Make sure they’re not touching or overlapping—air circulation is key to even cooking and crispiness. Depending on your air fryer size, you may need to cook in batches. Lightly spray the tops of the fillets with cooking spray.

Step 6: Air Fry to Perfection
Cook the catfish fillets at 400°F for 10-12 minutes, flipping halfway through at the 6-minute mark. When you flip them, spray the other side lightly with cooking spray. The fillets are done when they reach an internal temperature of 145°F and the coating is golden brown and crispy. The fish should flake easily with a fork.

Step 7: Rest and Serve
Remove the cooked fillets from the air fryer and let them rest for 2-3 minutes. This allows the juices to redistribute and the coating to set. Garnish with fresh parsley, serve with lemon wedges, and your favorite dipping sauce. Enjoy immediately while they’re hot and crispy!

Top Tips for Perfecting Air Fryer Catfish Fillets

Choose the Right Fish
Fresh catfish is ideal, but frozen fillets work perfectly too. Just make sure to thaw them completely and pat them very dry before breading. Look for fillets that are similar in size and thickness for even cooking. Wild-caught catfish tends to have a firmer texture, while farm-raised is milder and more tender.

Don’t Skip the Buttermilk Soak
Buttermilk is a game-changer for two reasons: it tenderizes the fish and creates a sticky surface for breading to cling to. If you don’t have buttermilk, make your own by adding 1 tablespoon of lemon juice or vinegar to 1 cup of regular milk. Let it sit for 5 minutes before using.

Press the Breading Firmly
The key to breading that stays put is pressing it firmly onto the fish. Don’t just dip and shake—really press that coating into both sides. This creates maximum contact and ensures you get crispy breading in every bite.

Avoid Overcrowding
Air fryers work by circulating hot air around the food. If you pile fillets on top of each other, you’ll get soggy breading instead of crispy perfection. Cook in batches if necessary, keeping finished fillets warm in a 200°F oven.

Use Cooking Spray Generously
The light mist of oil is what helps the breading achieve that golden, crispy exterior. Spray before cooking and after flipping. Avocado oil or olive oil sprays work best and add a subtle flavor boost.

Check for Doneness
Fish cooks quickly and can dry out if overdone. Use an instant-read thermometer to check for 145°F internal temperature. The fish should be opaque and flake easily with a fork but still be moist inside.

Adjust Spice Levels
If you’re cooking for kids or those sensitive to spice, reduce or omit the cayenne pepper. For spice lovers, increase it to ½ teaspoon or add a pinch of red pepper flakes to the breading mix.

Temperature Matters
Different air fryer models cook at slightly different rates. If your fillets aren’t crispy enough at 12 minutes, add 1-2 more minutes. If they’re browning too quickly, reduce temperature to 375°F and cook a bit longer.

Common Mistakes to Avoid

Not Drying the Fish Properly
Wet fish equals soggy breading. Take the extra 30 seconds to thoroughly pat your fillets dry with paper towels before the buttermilk soak. This simple step makes a huge difference in coating adhesion.

Using Old Breading
As you bread multiple fillets, the coating mixture can become clumpy with buttermilk. If it looks too wet, discard it and make a fresh batch. Soggy breading won’t crisp up properly.

Flipping Too Early
Resist the urge to flip before 6 minutes. The breading needs time to set and crisp. Flipping too soon can cause the coating to stick to the basket or fall off completely.

Skipping the Preheat
Preheating your air fryer creates an immediate sear that locks in moisture and starts the crisping process right away. Cold air fryers lead to uneven cooking and less crispy results.

Forgetting to Spray the Top
Many people spray the basket but forget to spray the fish itself. Both sides need that light coating of oil to achieve maximum crispiness and golden color.

Storing and Reheating Tips

Refrigerator Storage:
Allow cooked catfish fillets to cool completely before storing. Place them in an airtight container with paper towels between layers to absorb excess moisture. Properly stored, they’ll stay fresh for 3-4 days in the refrigerator. Avoid stacking them directly on top of each other to prevent the breading from becoming soggy.

Freezing Instructions:
For longer storage, catfish fillets freeze beautifully for up to 2 months. Wrap each fillet individually in plastic wrap, then place them in a freezer-safe bag or container. Remove as much air as possible to prevent freezer burn. Label with the date so you can track freshness.

Reheating in the Air Fryer:
This is the best method for restoring that crispy texture! Preheat your air fryer to 350°F. Place refrigerated fillets in a single layer and cook for 3-4 minutes until heated through and crispy again. For frozen fillets, increase time to 8-10 minutes, no thawing needed.

Oven Reheating:
Preheat your oven to 375°F. Place fillets on a wire rack over a baking sheet (this allows air circulation underneath). Bake for 10-12 minutes until heated through and crispy. Avoid using the microwave as it makes the breading soggy.

Make-Ahead Tips:
You can bread the fillets up to 4 hours in advance. Place them on a plate, cover loosely with plastic wrap, and refrigerate. The breading actually adheres better when it has time to set. Cook straight from the fridge, adding 1-2 extra minutes to the cooking time.

Frequently Asked Questions

Can I use a different type of fish for this recipe?
Absolutely! This breading and cooking method works wonderfully with tilapia, cod, haddock, or any white fish fillet. Thicker fish like salmon may need an extra 2-3 minutes of cooking time. Just ensure the internal temperature reaches 145°F.

Do I have to use cornmeal in the breading?
Cornmeal gives that authentic Southern fish fry texture, but you can substitute with panko breadcrumbs for a lighter, crunchier coating. You can also use a 50/50 mix of cornmeal and panko for the best of both worlds. Crushed cornflakes are another excellent alternative.

How do I know when the catfish is fully cooked?
The fish should reach an internal temperature of 145°F when measured with an instant-read thermometer. Visually, the flesh should be opaque white throughout and flake easily when tested with a fork. The coating should be golden brown and crispy.

Can I make this recipe without buttermilk?
Yes! You can use regular milk mixed with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes to create a buttermilk substitute. Plain yogurt thinned with a little milk also works well. Some people even use beaten eggs for the wet coating.

Why is my breading falling off in the air fryer?
This usually happens when the fish isn’t dried properly before breading, the coating isn’t pressed firmly enough, or the basket isn’t sprayed with oil. Make sure to follow all three steps: dry thoroughly, press breading firmly, and spray with cooking spray before and during cooking.

Can I cook frozen catfish fillets directly?
It’s best to thaw frozen catfish completely for even cooking and proper breading adhesion. Thaw in the refrigerator overnight or use the cold water method (sealed in a bag, submerged in cold water for 30-45 minutes). Pat very dry before proceeding with the recipe.

What’s the best oil spray to use?
Avocado oil, olive oil, or vegetable oil sprays all work great. Avoid butter-flavored sprays as they can burn at high temperatures. If you don’t have cooking spray, you can lightly brush the fillets with oil using a pastry brush.

How do I make the fish spicier?
Increase the cayenne pepper to ½ teaspoon in the breading, add hot sauce to the buttermilk soak, or serve with spicy remoulade or hot sauce on the side. You can also add red pepper flakes or chipotle powder to the breading mixture for extra kick.

Can I prepare these for meal prep?
Absolutely! Cook a double batch and store them properly. They reheat beautifully in the air fryer, making them perfect for quick lunches or dinners throughout the week. Just remember to store with paper towels to maintain some crispiness.

What size air fryer do I need?
Most standard air fryers (3.5-6 quarts) will fit 2-3 fillets at a time. Larger models (8+ quarts) can handle all 4 fillets in one batch. The key is ensuring fillets don’t overlap for proper air circulation and even crisping.

Additional Tips for Success

Choosing Quality Catfish:
Look for fillets that are firm to the touch with a mild, fresh smell. Avoid any fish with a strong “fishy” odor or mushy texture. U.S. farm-raised catfish is a sustainable choice and has consistent quality year-round.

Creating Variations:
Try different seasoning blends to change the flavor profile. Old Bay seasoning creates a Maryland-style fish, Italian herbs make it Mediterranean, or use taco seasoning for fish tacos. The possibilities are endless!

Serving Size Adjustments:
These portions are generous. If serving to children or alongside multiple sides, one fillet can easily serve two people. Cut larger fillets into strips for catfish “fingers” that are perfect for kids and easier to eat.

Wine Pairing Suggestions:
The crispy, seasoned catfish pairs beautifully with crisp white wines. Try Sauvignon Blanc, Pinot Grigio, or a dry Riesling. The acidity cuts through the richness while complementing the delicate fish flavor.

Making it a Fish Fry Party:
Double or triple the recipe for entertaining! Set up a DIY fish fry station with various dipping sauces, coleslaw, and hushpuppies. Keep finished batches warm in a 200°F oven while you cook more.
