Ingredients You’ll Need
This recipe keeps things simple but packed with essential ingredients that build layers of texture and flavor. Each element plays its part, from the tangy buttermilk that tenderizes the fish to the golden cornmeal that crisps it up beautifully.
- Buttermilk (1/3 cup): Adds moisture and helps tenderize the catfish for a juicy bite.
- Large egg (1): Acts as a binder, helping the coating stick perfectly to the fish.
- Cornmeal (1/2 cup): Provides that hallmark crunch and beautiful golden color.
- All-purpose flour (1/3 cup): Balances the texture and helps the dredge hold together crisply.
- Cajun seasoning (1 tablespoon): Brings a flavorful kick that complements the mild catfish wonderfully.
- Salt: Adjust to taste to enhance all the flavors.
- Black pepper (1/4 teaspoon): Adds a subtle warmth and depth to the seasoning.
- Catfish (1 pound), cut into 1-inch pieces: The star of the show—fresh, firm fillets work best.
How to Make Air Fryer Crispy Catfish Nuggets Recipe
Step 1: Preheat Your Air Fryer
Always start by preheating your air fryer to 390°F. This ensures the basket is hot enough to crisp the nuggets evenly right when they hit the surface, giving you that irresistible crunch without sogginess.
Step 2: Prepare the Wet Mixture
In a shallow bowl, whisk together the buttermilk and egg until fully blended. This mixture not only helps the coating adhere but also adds tangy richness that keeps the nuggets moist inside.
Step 3: Mix the Dry Coating
Combine the cornmeal, all-purpose flour, Cajun seasoning, salt (if using), and black pepper in another shallow bowl. Mix thoroughly so every nugget gets an even, flavorful coating that crisps perfectly.
Step 4: Bread the Catfish Nuggets
Start by dredging each catfish piece in the dry mixture, then dip it into the wet buttermilk and egg mixture. Let excess drip off before coating it once again in the dry mixture. This double dredging forms a gloriously crispy crust when air fried. Set the breaded nuggets aside on a clean plate.
Step 5: Prepare the Air Fryer Basket
Spray your air fryer basket lightly with olive oil spray. This step is key to preventing the nuggets from sticking and promotes even browning. Arrange the breaded catfish nuggets in the basket with some space around each piece to allow air circulation.
Step 6: Cook in Batches
If your air fryer isn’t large enough to fit all the nuggets without crowding, cook them in batches. Air fry for about 5 minutes, flipping the nuggets halfway through cooking to ensure uniform crispiness. The catfish should reach an internal temperature of 145°F when done, guaranteeing safety and flakiness.
Step 7: Serve Immediately
Once cooked to perfection, serve these crunchy catfish nuggets hot with your favorite dipping sauces. Whether it’s tartar, ranch, or a spicy mayo, these nuggets are irresistible right off the air fryer.

Garnishes
Simple garnishes like freshly chopped parsley or a squeeze of lemon not only brighten the dish visually but also add fresh, zesty notes that balance the crispy, savory nuggets beautifully.
Side Dishes
Classic sides like coleslaw, crispy fries, or a refreshing cucumber salad pair wonderfully with these nuggets. They add complementary textures and flavors that elevate the whole meal experience.
Creative Ways to Present
Beyond a casual snack, try serving the Air Fryer Crispy Catfish Nuggets Recipe in mini slider buns with lettuce and remoulade sauce for a fun seafood sandwich twist. Alternatively, toss them over a crisp green salad for a light yet satisfying lunch.
Make Ahead and Storage
Storing Leftovers
Leftover catfish nuggets keep well in an airtight container in the refrigerator for up to 2 days. Store them separately from any dipping sauce to maintain their crispness.
Freezing
If you want to enjoy these nuggets later, freeze them on a baking sheet in a single layer until firm. Then transfer to a freezer-safe bag or container. They can be frozen for up to 1 month without losing texture.
Reheating
To reheat and keep that crunch, pop the nuggets back into the air fryer at 375°F for 3-4 minutes. Avoid microwaving, as it softens the coating and makes them soggy.
FAQs
Can I use frozen catfish for this recipe?
Yes, you can use frozen catfish, but make sure to fully thaw and pat the pieces dry before breading. Excess moisture will prevent the coating from sticking properly and affect crispiness.
Is it necessary to use buttermilk?
Buttermilk is ideal because it tenderizes the fish and adds tangy flavor, but if you don’t have any, you can substitute with milk mixed with a teaspoon of lemon juice or vinegar.
Can I make this recipe gluten-free?
Absolutely! Swap the all-purpose flour with a gluten-free flour blend and use gluten-free cornmeal to keep the coating crispy and safe for gluten-sensitive diets.
What dipping sauce goes best with these catfish nuggets?
Tartar sauce is a classic pairing, but spicy mayo or ranch dressing also complement the Cajun spices beautifully. Feel free to get creative with your favorite sauces!
How do I know when the catfish nuggets are cooked through?
The nuggets are perfectly cooked when the internal temperature reaches 145°F and the fish flakes easily with a fork. The coating should be golden and crunchy on the outside.
