Why this Recipe is a Keeper
These nuggets check every box for a go-to fish dinner. Here’s why this one earns a permanent spot in your rotation.
- Speed: Ready start to finish in just 20 minutes.
- Crispy Coating: The double-dredge cornmeal method gives you serious crunch.
- Bold Flavor: Cajun seasoning does all the heavy lifting.
- Family Friendly: Kid-approved nugget shape makes dinner drama-free.
Can I Use Frozen Catfish for this Recipe?
Yes, you can, but you’ll want to thaw it completely first. Pat the fish dry with paper towels before you slice it into pieces. Excess moisture is the enemy of a crispy crust.
Frozen catfish often releases more water as it thaws, so don’t skip the drying step. Once it’s fully thawed and dried, it works just as well as fresh. The coating adheres better and crisps up beautifully in the air fryer when the surface is dry.
Pro Tip
Do your double-dredge in order: cornmeal first, then the egg-milk mixture, then back into the cornmeal. That first cornmeal layer gives the wet coating something to grip. The second cornmeal layer is what creates that extra-thick, ultra-crispy crust you’re after.
Ingredient Notes
You likely have most of these ingredients already sitting in your pantry. Here are a few worth calling out.
This is an overview of key ingredients. Get the full printable recipe with specific measurements and directions in the recipe card below.
- Catfish: Fresh fillets work best — cut them into uniform 1-inch pieces for even cooking.
- Buttermilk: Adds a subtle tang and helps the coating stick beautifully to the fish.
- Cornmeal: This is the backbone of the crust — don’t swap it for breadcrumbs or you’ll lose that classic crunch.
- Cajun Seasoning: Store-bought works great — choose your heat level based on your crowd.
- Salt and Pepper: These round out the seasoning in the cornmeal coating alongside the Cajun blend.
Variations and Substitutions
This recipe is flexible — it’s easy to make it your own. Small swaps can change the flavor profile without touching the technique.
➡️ Swap the fish: Use tilapia, cod, or bass cut into 1-inch pieces as a direct substitute.
➡️ Reduce the heat: Use a mild Cajun seasoning or cut the amount to 1½ teaspoons for a gentler flavor.
➡️ Add more kick: Mix in ½ teaspoon cayenne pepper to the cornmeal coating.
➡️ Make it gluten-free: Replace the all-purpose flour with a one to one gluten-free flour blend.
➡️ Try a different coating: Substitute half the cornmeal with Panko for a lighter, crunchier texture.
Special Equipment Needed To Make It Easier
You don’t need much to pull this recipe off. A couple of key tools make the process smoother.
- Air fryer: Essential for this recipe — any basket-style or tray-style model works.
- Two shallow bowls: One for the wet mixture, one for the dry coating — wide bowls make dredging much easier.
- Food thermometer: The fish should hit an internal temperature of 145°F — a thermometer takes the guesswork out completely.
How to Make the Recipe
This is a simple, repeatable process you’ll have memorized after the first time.
These are just highlights. Get the full printable recipe with specific measurements and directions in the recipe card below.
- Preheat your air fryer to 390°F.
- Set up your dredging station with the buttermilk-egg mixture in one bowl and the seasoned cornmeal mixture in another.
- Coat the catfish in cornmeal, then the egg mixture, then cornmeal again.
- Air fry in batches for five minutes, flipping or shaking halfway through.
- Check the temp and serve immediately.
Prep Ahead and Short Cut Tips
A little prep goes a long way with this recipe. These tips save you time when it’s actually dinner time.
➡️ Mix the dry coating ahead: Combine the cornmeal, flour, Cajun seasoning, salt, and pepper up to three days in advance — store it in an airtight container.
➡️ Cut the fish early: Slice the catfish into one inch pieces and refrigerate on a covered plate for up to 24 hours before cooking.
➡️ Prep the wet mixture early: Whisk the buttermilk and egg together and refrigerate it in a covered bowl up to a day ahead.
➡️ Batch cook strategically: Bread all the nuggets before you start air frying so the process moves quickly.
Alternate Cooking Methods
The air fryer is ideal here, but you have other solid options if you need them.
- Oven-Baked: Place breaded nuggets on a wire rack set over a baking sheet. Bake at 425°F for 12–15 minutes, flipping once halfway through. Spray lightly with cooking spray before baking for a crispier result.
- Pan-Fried: Heat about half inch of oil in a skillet over medium-high heat. Fry the nuggets for two to three minutes per side until golden brown and cooked through to 145°F internally. Drain on a paper towel-lined plate before serving.
How Do I Know When Air Fryer Catfish Nuggets are Fully Cooked?
The most reliable method is a food thermometer. Catfish nuggets are safe to eat when the internal temperature reaches 145°F — that’s the USDA standard for fish. If you don’t have a thermometer, look for these visual cues: the coating should be deep golden brown, and the fish should flake easily when you press it with a fork.
Because you’re cutting the catfish into small one inch pieces, they cook quickly and evenly at 390°F. Thicker pieces may need an extra minute or two, so always check before serving.
How to Store, Reheat, and Use Leftovers
- Storing: Let the nuggets cool completely before storing. Place them in an airtight container and refrigerate for up to three days.
- Reheating: The air fryer is your best friend for leftovers here. Reheat at 375°F for three to four minutes until hot and crispy again. Avoid the microwave — it makes the coating soft and rubbery.
- Using Leftovers: Chop leftover nuggets and tuck them into fish tacos with slaw and a squeeze of lime. They also work great over a salad or stuffed into a hoagie roll with remoulade sauce for a quick po’boy-style sandwich.
Expert Tips for Making This Recipe
I’ve made these enough times to know exactly what separates a good batch from a great one.
➡️ Don’t skip the preheat. A preheated air fryer at 390°F starts crisping the coating the moment the nuggets go in — skipping it leads to soggy bottoms.
➡️ Cook in batches. Crowding the basket traps steam and ruins the crunch — give each nugget space so the hot air circulates freely.
➡️ A light spritz of cooking spray helps. Even though it’s not listed in the recipe, a quick spray of oil on the breaded nuggets before cooking pushes the crust into extra-crispy territory.

- ⅓ Cup All-purpose flour
- 1 Tablespoon Cajun seasoning
- 1 teaspoon Salt
- 1 teaspoon Pepper
Instructions
- Preheat the air fryer to 390°F.
- Cut the catfish into 1-inch pieces and set aside.
- In one shallow bowl, whisk together the buttermilk and egg.
- In a second shallow bowl, stir together the cornmeal, flour, Cajun seasoning, salt, and pepper until well combined.
- Coat each catfish nugget in the cornmeal mixture, then dip it into the buttermilk mixture, and coat it once more in the cornmeal mixture.
- Arrange the breaded catfish nuggets in the preheated air fryer basket in a single layer, working in batches if necessary.
- Air fry for 5 minutes, shaking the basket or flipping the nuggets halfway through cooking.
Christina’s Notes
- Start with dry fish. Pat your catfish pieces completely dry before you bread them. Moisture under the coating causes steaming instead of crisping.
- Cut uniform pieces. Aim for true 1-inch chunks. Consistent sizing means every piece finishes cooking at the same time — no overdone edges and raw centers.
- Use the double-dredge method. The order matters: cornmeal first, egg-milk mixture second, cornmeal again last. This is what builds a thick, crunchy crust that holds together.
- Preheat your air fryer to 390°F. Don’t add the nuggets to a cold air fryer. The immediate high heat is what locks in crunch from the start.
- Cook in batches. Never stack or crowd the nuggets. A single layer with space between each piece is non-negotiable for even browning.
- Flip or shake at the halfway mark. Set a timer and flip at 2½ minutes so both sides get equal exposure to the hot circulating air.
- Check the internal temperature. Pull out your food thermometer and confirm 145°F before serving. Thicker pieces may need 1–2 extra minutes.
- Serve immediately. Air fryer nuggets are best the moment they come out. The crust softens as they sit, so plate them fast and eat them hot.
- Scale the recipe: Simply adjust the serving size in the recipe card and the ingredients will update automatically.
- Make your own All Purpose Seasoning: When a recipe calls for All Purpose Seasoning, you can use my homemade All Purpose Seasoning recipe or substitute salt and pepper to taste.
- Meat doneness: I always use a meat thermometer to test for doneness when cooking meat.
- Use unsalted butter: I use unsalted butter so I can control the salt level in the recipe.
- Preheat the oven: Unless otherwise noted, always preheat your oven before baking.
