If you are trying to decide on what air fryer to get, I have a great list of the best air fryers for gluten free. I include a great pros and cons list for each model.
Ingredient Notes:
- Catfish - Use either filets or catfish nuggets. Always give the fish a quick check and remove any bones you find!
- Cornmeal - Although cornmeal is naturally gluten free, I advise buying Bob's Red Mill or another brand that is labeled gluten free. This way, you avoid cross-contamination issues.
- Buttermilk - You can also use regular milk. I typically make my buttermilk by adding 1 tablespoon of lemon juice to the soaking milk. This also gives a nice lemon flavor to the fish.
- Gluten Free Flour Blend - Any blend should work well. It does not need to contain Xanthan Gum. You can also use my gum-free DIY Gluten Free Flour Blend.
- Creole Seasoning - I like to use Zaitarain's brand. This brand is gluten free.
- Paprika - I used Hungarian paprika, not smoked.

This Ninja Foodi is one of my favorites. You can set different cooking temperatures and times for each side so that you can cook a whole meal easily. Clean-up is effortless too!
- 1. This model has two separate fans and is the only air fryer that I recommend for a household where all members are not gluten free.
- 2. Easy clean-up.
- 3. It cooks food evenly.
- 1. You must clean it very well after cooking meat to avoid any smell when you use it at a later date.
Recipe Step-By-Step Directions:
Step 1: Add the buttermilk to a large bowl and gently place the catfish fillets (or nuggets) into the milk. If you don't have buttermilk, it is easy to make by adding lemon juice to milk. See Recipe Notes for the directions to make your own buttermilk above.
Why do you soak the catfish?
Many ask me why catfish needs to be soaked or if it is even necessary. The reason is that it takes away the fishy flavor. (If you have picky kids, this is even more important!) You will want to soak your catfish for 30 minutes.
Step 2: Mix up the cornmeal seasoning mix in a large bag. Place the cornmeal fish breading and seasoning ingredients into a large bag and shake to mix it up. When the catfish is done soaking in buttermilk, hold the catfish over the bowl to allow the extra milk to run off.
Place the catfish or nuggets in the bag, one fillet at a time. Shake gently so the raw catfish fillet is coated in the catfish breading mixture.
I love using my 8 qt Ninja Air Fryer because it has two separate compartments, making it easy to cook a whole meal at once. If you don't need a big air fryer, this little 3.4 qt Corsori Air Fryer will do the job as well. Make sure whichever air fryer you buy is dishwasher safe so you have easy cleanup!
Preheat your air fryer to 375º F.
Step 3: Spray the bottom grill of the air fryer with a high heat oil like avocado or canola. Place a breaded catfish fillet in the air fryer.
Do not use olive oil or another low-smoke point oil, or your fish will turn out rancid. See the Recipe FAQ for a list of high smoke point oils for the air fryer.
Step 4: Spray the top of the gluten free breaded catfish with more oil. This will help the crust get nice and crispy!
Step 5: Cook your catfish in the air fryer for 12-15 minutes. The actual cook time will vary depending on the size of your catfish fillets and whether you use catfish nuggets or fillets. You will know the catfish is done cooking when it is crispy and the cornmeal breading is golden.
If you are making air fryer catfish nuggets, they will need to cook less time in the air fryer. Cook for 6 minutes and then check on them to see if they need more time. This will vary depending on the size of your catfish nuggets.
*Note: many will recommend flipping your catfish over partway through the cooking cycle. I find this difficult without the catfish falling apart in the air fryer. It is up to you if you want to try this. I did not flip it, and my catfish was still crispy and delicious on both sides.
Drizzle the cooked catfish with lemon juice. Serve with my fluffy Gluten Free Air Fryer Dinner Rolls and some French fries!
I absolutely love my 12-inch cast iron skillet. I use it for pancakes, skillet cakes, and many of my dinner recipes. It is easy to clean, and perfectly non-stick!
Frying Catfish Stovetop:
- To fry your catfish in oil on your stovetop, follow steps 1 and 2 above. In a Dutch oven or cast-iron skillet, heat your oil. I recommend using either avocado or canola oil. It is very important to use an oil that can tolerate high heat.
- Heat the oil to 350-375º F. Gently add a piece of breaded catfish. If you are using catfish fillets, fry one filet at a time. If you are frying catfish nuggets, you can fry several together as long as they don't touch.
- Cook in the hot oil for 3 minutes and flip it gently with tongs. Be careful of the hot oil splashing. Cook for 3 minutes on the other side.
- Use a long metal slotted spoon to move the fried catfish from the hot oil to a paper towel-lined plate. The paper towel will help absorb extra oil from frying. * If your catfish is thick, it may need to cook longer on each side.
Serve Catfish With:
Fried catfish is often served with sides, including coleslaw, gluten free hush puppies, gluten free macaroni salad, and tartar sauce. It is a delicious and flavorful dish that many people worldwide enjoy.
Tips and Recipe FAQ:
I know I talked about this above, but it is essential. I highly recommend soaking the raw catfish in buttermilk or milk to remove that fishy flavor.
You need to use an oil that can handle high heat. My favorites are canola, avocado, and grapeseed.
Yes! You can cook moist and delicious fish recipes in the air fryer.
Frozen fish cooked in the air fryer does not turn out well because of the moisture from being frozen. It is best to thaw the fish and pat it dry before seasoning and cooking.
Store the fried catfish in an airtight container for up to 3 days. The catfish will keep up to 3 days in the refrigerator, but it will lose its crispiness. To re-crisp, reheat in the oven at 325º for 15 minutes or the air fryer for 7 minutes at 350º F.

My son also has a milk and egg allergy. Would this recipe still work well if I use coconut or rice milk?
Sandi Gaertner
Hi Angel, non-dairy milk will work well, you may consider using Just Egg or another egg replacer so the batter sticks better to the fish.
Vera Moore
I did buttermilk/hot sauce soak and dredged in cornmeal/all purpose flour seasoned with Slap ya' Mama and Lemon Pepper. When trying to flip the bottom breading immediately fell off with not much resistance. Next time I will add egg to the buttermilk for a better binding. Otherwise 15 minutes at 400F was perfect for the filets. Very tender and flakey!
Sandi Gaertner
Please do let me know how it turns out with the egg. Thank you so much!
Ashley

I am so glad Ashley.

Oh yum! This looks so good. I love the spices you used here and the coating looks amazing. I can't wait to make this for my family. We love fish & chips on Fridays!
Sandi Gaertner
Thank you so much Natalie.
Pam R.
Would this work with crappie or bream filets?
Sandi Gaertner
Hi Pam, I am not sure how thick they are, but yes, this would work for them...you may need to cook longer if they are thicker, or less if they are thinner.
