Key Ingredients for Air Fryer Cajun Catfish
For the Catfish:
- 4 catfish fillets (6-8 oz each, fresh or thawed)
- 2 tablespoons olive oil or melted butter
- 1 tablespoon lemon juice
For the Cajun Seasoning:
- 2 teaspoons paprika (sweet or smoked)
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1/2 teaspoon cayenne pepper (adjust to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt
- 1/4 teaspoon white pepper (optional)
Optional for Extra Crispiness:
- 1/4 cup cornmeal or breadcrumbs

Step-by-Step Instructions
Step 1: Prepare the Catfish
Start by patting the catfish fillets completely dry with paper towels. This crucial step removes excess moisture, which allows the seasoning to adhere better and helps achieve maximum crispiness. If your fillets are frozen, ensure they’re fully thawed and dried thoroughly.
Step 2: Mix the Cajun Seasoning
In a small bowl, combine paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, salt, and white pepper. Mix well until all spices are evenly distributed. This creates about 3 tablespoons of seasoning—you can double the recipe and store extras in an airtight container for up to 3 months.
Step 3: Season the Fish
Brush both sides of each catfish fillet with olive oil or melted butter, then drizzle with lemon juice. The oil helps the spices stick and promotes browning, while lemon brightens the flavors. Generously sprinkle the Cajun seasoning over both sides of the fillets, pressing gently to ensure it adheres. Don’t be shy—the seasoning creates that delicious crust!
Step 4: Preheat the Air Fryer
Preheat your air fryer to 400°F (200°C) for 3-5 minutes. Preheating ensures even cooking and helps achieve that crispy exterior. While it preheats, lightly spray the air fryer basket with cooking spray to prevent sticking.
Step 5: Arrange the Fish
Place the seasoned catfish fillets in a single layer in the air fryer basket, making sure they don’t overlap. If your fillets are thick, place the thicker portions toward the center where heat circulates most intensely. Leave a little space between fillets for optimal air circulation.
Step 6: Air Fry the Catfish
Cook at 400°F for 10-12 minutes, flipping halfway through at the 5-6 minute mark. The fish is done when it reaches an internal temperature of 145°F and flakes easily with a fork. Thicker fillets may need an extra 2-3 minutes. The exterior should be golden brown and crispy.
Step 7: Rest and Serve
Remove the catfish from the air fryer and let it rest for 2 minutes. This allows the juices to redistribute throughout the fish. Serve immediately with fresh lemon wedges and your favorite sides for maximum enjoyment!

Top Tips for Perfecting Air Fryer Cajun Catfish
Choose Quality Fish
Fresh catfish works best, but frozen is perfectly fine if properly thawed. Look for fillets that are moist, firm, and smell fresh—never fishy. Wild-caught catfish offers firmer texture, while farm-raised is milder and more buttery.
Don’t Skip the Oil
Oil isn’t just for flavor—it’s essential for achieving that crispy, golden crust. The oil helps conduct heat and promotes browning. Use olive oil, avocado oil, or melted butter for best results.
Adjust Spice Level
Too spicy for kids? Reduce cayenne to 1/4 teaspoon or omit entirely. Want more heat? Add extra cayenne or a pinch of red pepper flakes. You can also offer hot sauce on the side for those who like it extra spicy.
Avoid Overcrowding
Cook in batches if necessary. Overcrowding prevents proper air circulation, resulting in steamed rather than crispy fish. Each fillet needs space for the hot air to circulate completely around it.
Check for Doneness
Fish cooks quickly and can dry out if overcooked. Check at the 10-minute mark—the fish should be opaque, flake easily, and reach 145°F internally. If needed, cook in 1-minute increments.
Use Parchment Paper
For easier cleanup, use perforated air fryer parchment paper. It won’t affect cooking but makes removing delicate fish much easier and prevents sticking.
Try a Cornmeal Coating
For extra Southern-style crunch, lightly dust seasoned fillets with cornmeal before air frying. This creates an even crispier crust reminiscent of traditional fried catfish.
Storing and Reheating Tips
Refrigerator Storage:
Store leftover air fryer Cajun catfish in an airtight container in the refrigerator for up to 3 days. Let the fish cool to room temperature first, then transfer to a container. Place parchment paper between fillets to prevent them from sticking together.
Freezing Instructions:
While best eaten fresh, you can freeze cooked catfish for up to 2 months. Wrap each fillet individually in plastic wrap, then place in a freezer-safe bag. Label with the date. Thaw overnight in the refrigerator before reheating.
Reheating Methods:
The air fryer is the best reheating method to restore crispiness. Reheat at 350°F for 3-4 minutes until warmed through. Avoid the microwave, which makes the coating soggy. You can also reheat in a conventional oven at 350°F for 8-10 minutes.
Pro Tip: Leftover catfish makes excellent fish tacos the next day! Flake the fish and warm it in the air fryer, then serve in tortillas with coleslaw and hot sauce.
Tips for Avoiding Common Cooking Mistakes
Mistake #1: Using Wet Fish
The biggest mistake is not drying the catfish properly. Excess moisture creates steam, preventing the crust from crisping. Always pat fillets bone-dry with paper towels before seasoning.
Mistake #2: Underseasoning
Catfish has a mild flavor that needs bold seasoning. Don’t be timid—use the full amount of Cajun spices. The seasoning forms a flavorful crust that’s the star of this dish.
Mistake #3: Wrong Temperature
Cooking at too low a temperature results in soggy fish. The high heat of 400°F is essential for achieving that crispy exterior while keeping the inside moist. Don’t reduce the temperature thinking it will be “safer.”
Mistake #4: Skipping Preheating
Always preheat your air fryer. Starting with a cold air fryer leads to uneven cooking and prevents proper crisping. Those 3-5 minutes make a huge difference.
Mistake #5: Not Flipping
Flipping halfway through ensures even browning on both sides. Set a timer so you don’t forget this crucial step!
Mistake #6: Overcooking
Fish continues cooking for a minute or two after removal due to residual heat. Pull it out when it just reaches 145°F—it will continue to firm up as it rests.
Frequently Asked Questions
Can I use frozen catfish fillets?
Yes, but you must thaw them completely first. Pat them very dry with paper towels to remove all moisture. Cooking frozen fish directly will result in soggy, unevenly cooked fillets.
What can I substitute for catfish?
Any firm white fish works beautifully with this Cajun seasoning. Try tilapia, cod, swai, haddock, or grouper. Adjust cooking time based on fillet thickness—thinner fish may need only 8 minutes.
How do I know when the catfish is done?
The fish should be opaque throughout, flake easily with a fork, and reach an internal temperature of 145°F. The exterior will be golden brown and crispy. Undercooked fish appears translucent and doesn’t flake.
Can I make this recipe less spicy?
Absolutely! Reduce or omit the cayenne pepper. You can also use more paprika to maintain the coating volume while reducing heat. The other spices still provide great flavor without the burn.
Why is my catfish soggy instead of crispy?
This usually happens when the fish isn’t dried properly before seasoning, the air fryer is overcrowded, or the temperature is too low. Make sure to pat fish dry, don’t overlap fillets, and cook at the full 400°F.
Can I double this recipe?
Yes, but cook in batches. Don’t overcrowd the air fryer basket or the fish won’t crisp properly. Keep the first batch warm in a 200°F oven while cooking the second batch.
Do I need to spray the catfish with oil during cooking?
No, the initial brushing of oil is sufficient. However, if your fillets look dry halfway through, a light spritz of cooking spray won’t hurt and may enhance crispiness.
What’s the best way to get the seasoning to stick?
Brushing with oil or butter first is key—the fat helps the dry spices adhere to the fish. Press the seasoning gently into the fish with your fingers for better adhesion.
Can I use store-bought Cajun seasoning?
Yes! Store-bought Cajun or blackening seasoning works great. Use about 2-3 tablespoons total. Check the salt content first—if it’s already salty, reduce or omit added salt.
How do I prevent the fish from sticking to the basket?
Lightly spray the air fryer basket with cooking spray before adding fish. You can also use perforated parchment paper designed for air fryers. The oil brushed on the fish also helps prevent sticking.
