Gluten-Free Cajun Buttermilk Deep-Fried Chicken Wings
These are the chicken wings that ruin every other chicken wing for you. A full overnight soak in Cajun-seasoned buttermilk that penetrates every layer of the meat, a coating built from Louisiana Fish Fry, gluten-free flour, cornstarch, and enough Cajun seasoning and garlic powder to flavor every single bite, and a deep fry in cast-iron at 350°F until the crust is golden, shatteringly crispy, and holding on with everything it has. They’re gluten-free without any compromise in crunch or flavor, and they taste more authentically Southern than most wings you’ll find anywhere.

The overnight marinade is non-negotiable. Buttermilk is acidic enough to gently tenderize the meat over 12 hours while the Cajun seasoning and garlic powder infuse deep into the wing rather than sitting on the surface. By the time the wings hit the coating bag they’re already seasoned all the way through, which means the crust isn’t doing all the flavor work on its own. The cornstarch in the coating is the gluten-free trick that delivers that signature crackly shatter when you bite through it.
Ingredients Needed to Make Gluten-Free Cajun Chicken Wings
Two components, both straightforward. Here’s what you need:
The Marinade
- Chicken wings (drums and flats separated or whole; 2 to 3 pounds feeds 4 to 6 people as a main)
- Buttermilk (the acidic base that tenderizes the meat and helps the coating adhere)
- Cajun seasoning (seasons the meat all the way through during the overnight soak)
- Garlic powder (adds a deep, savory note that permeates the wing during marinating)
The Coating
- Louisiana Fish Fry seasoned coating mix (the star ingredient that gives these wings their distinctly Southern, slightly seasoned crust; it’s gluten-free as packaged)
- Gluten-free flour (provides the bulk of the coating structure without any wheat)
- Cornstarch (the ingredient responsible for the shatteringly crispy crust; absorbs moisture and fries up drier than flour alone)
- Garlic powder (layered again in the coating for bold flavor throughout the crust)
- Cajun seasoning (seasons the crust itself so the flavor is present on the outside as well as in the meat)
- Onion powder (adds savory depth to the coating)
For Frying
- Peanut oil, lard, or tallow (peanut oil for a clean, high-heat fry with subtle richness; tallow for the most flavorful, old-school Southern result; lard falls between the two)
How to Make Cajun Buttermilk Gluten-Free Chicken Wings
Marinate overnight, coat, and fry. Most of the time is hands-off.
Step 1: Marinate Overnight
Combine the buttermilk, Cajun seasoning, and garlic powder in a gallon zip-lock bag. Add the chicken wings, seal the bag, and work it with your hands to make sure every wing is fully submerged and coated in the seasoned buttermilk. Place the sealed bag in a bowl or on a rimmed baking sheet in case of leaks and refrigerate for at least 12 hours, or overnight. The longer they sit the more deeply seasoned and tender the finished wings will be.
Step 2: Heat the Oil
When ready to fry, pour your chosen oil into a double burner cast-iron pot to a depth of about 4 inches. Heat to 350°F, checking with a thermometer. Cast iron holds and distributes heat exceptionally evenly and is the best vessel for deep frying chicken wings at volume. Let the oil fully come to temperature before adding any wings.
Step 3: Prepare the Coating
In a separate gallon zip-lock bag, combine the Louisiana Fish Fry, gluten-free flour, cornstarch, garlic powder, Cajun seasoning, and onion powder. Seal the bag and shake thoroughly until everything is evenly blended. The coating bag method coats wings faster and more completely than a bowl and produces less mess.
Step 4: Coat the Wings
Remove 6 to 8 wings from the marinade at a time and let the excess buttermilk drip off. Drop them into the coating bag, seal, and shake vigorously until every surface of every wing is fully and evenly coated. The buttermilk still clinging to the wings acts as a binder that helps the coating adhere. Don’t shake off too much before coating.
Step 5: Fry in Batches
Carefully lower the coated wings into the hot oil one at a time using tongs. Don’t crowd the pot. Frying too many wings at once drops the oil temperature significantly and produces greasy, pale, undercooked wings rather than golden crispy ones. Fry for 8 to 12 minutes depending on the size of the wings until deep golden brown and cooked to an internal temperature of 165°F. Let the oil return to 350°F between batches.
Step 6: Drain on a Wire Rack
Remove the wings from the oil and place them on a wire rack set over a baking sheet rather than on paper towels. The wire rack allows air to circulate completely around the wings so the bottom crust stays as crispy as the top. Paper towels trap steam underneath and soften the bottom crust. If making a large batch, keep the finished wings in a 250°F oven on the wire rack while you fry the remaining batches.
Step 7: Serve
Serve immediately while the crust is at its peak crunch with your favorite dipping sauces alongside.
Storing and Reheating
Fried chicken wings are best eaten immediately after cooking when the crust is at its maximum crunch. That said, leftovers keep in the refrigerator for up to 3 days in an airtight container. The crust will soften as it sits and especially after refrigerating.
To reheat and restore as much crunch as possible, place the wings on a wire rack on a baking sheet and bake in a 400°F oven for 12 to 15 minutes until heated through and the crust has re-crisped. The air fryer at 375°F for 6 to 8 minutes is even better for restoring crunch. Avoid the microwave which steams the crust and produces a soft, soggy result.
How to Serve Cajun Buttermilk Chicken Wings
Serve straight from the wire rack onto a large platter with dipping sauces in small bowls alongside. Ranch dressing, blue cheese, Granny Sue’s Crawfish Dip Sauce, and a bowl of Louisiana hot sauce are all excellent companions for wings this boldly flavored. A squeeze of fresh lemon or lime over the platter right before serving adds brightness that cuts through the richness of the fry.
Frequently Asked Questions About Gluten-Free Chicken Wings
Is Louisiana Fish Fry gluten-free?
Yes. Louisiana Fish Fry Products seasoned coating mix is made with corn flour and does not contain wheat, making it naturally gluten-free. It’s widely available at grocery stores throughout the South and online. Always check the label on the specific product you purchase since formulations can vary and cross-contamination warnings differ by facility. The original seasoned variety is the one called for in this recipe.
Why use cornstarch in the coating?
Cornstarch absorbs moisture from the surface of the wing more aggressively than flour, which produces a drier, crispier crust when it hits the hot oil. It also creates a lighter, more delicate texture than flour-only coatings, which can be dense and heavy. The combination of Louisiana Fish Fry, gluten-free flour, and cornstarch creates a layered coating with crunch from multiple sources that is significantly crispier than any single-ingredient coating would produce.
Why does the overnight marinade matter so much?
Buttermilk is mildly acidic, which means it very slowly breaks down the surface proteins of the chicken over time, tenderizing the meat and opening it up to absorb flavors more deeply. After 12 hours in Cajun-seasoned buttermilk the meat is noticeably more tender and the seasoning has penetrated beyond just the surface. Wings marinated for only 30 minutes will still be good but the difference between a 30-minute and a 12-hour marinated wing in terms of flavor and tenderness is significant and worth the planning ahead.

Ingredients
Method
- In a gallon zip-lock bag, combine the buttermilk, Cajun seasoning, and garlic powder. Add the chicken wings, seal, and massage the bag until every wing is fully coated. Place the bag in a bowl and refrigerate overnight or for at least 12 hours.
- When ready to fry, heat the oil in a double burner cast-iron pot to 350°F. Use a thermometer and maintain the temperature throughout frying.
- In a separate gallon zip-lock bag, combine the Louisiana Fish Fry, gluten-free flour, cornstarch, garlic powder, Cajun seasoning, and onion powder. Seal and shake to blend.
- Working in batches of 6 to 8 wings, remove the wings from the marinade and let the excess drip off. Place them in the coating bag, seal, and shake until fully and evenly coated.
- Fry the wings in batches for 8 to 12 minutes until golden brown and cooked through to an internal temperature of 165°F. Don’t crowd the pot.
- Remove the wings and place on a wire rack to drain. The wire rack keeps air circulating around the wings so the crust stays crispy rather than steaming and going soft.
- Serve hot with your favorite dipping sauces.
