Crispy Catfish Nuggets with Cajun Dipping Sauce Recipe
Introduction
Crispy Catfish Nuggets with Cajun Dipping Sauce offer a flavorful and crunchy bite that’s perfect for snacking or a casual meal. Coated in a seasoned cornmeal crust and paired with a zesty sauce, these nuggets bring Southern charm to your kitchen.

Ingredients
- 1 ½ lbs catfish fillets (about 4 fillets), cut into nugget-sized pieces
- ½ cup buttermilk
- 2 teaspoons Creole Cajun Seasoning (homemade or store-bought), divided
- 2 teaspoons Old Bay seasoning, divided
- ½ teaspoon ground mustard
- ½ cup all-purpose flour
- ½ cup fine yellow cornmeal
- 1 tablespoon cornstarch
- Oil, for deep frying (peanut oil recommended)
- Lemon wedges, for serving
- ½ cup full-fat mayonnaise (Duke’s preferred)
- ¼ cup ketchup
- 1 tablespoon garlic paste
- 1 tablespoon lemon juice
Instructions
- Prep the Cajun dipping sauce: In a small bowl, combine mayonnaise, ketchup, garlic paste, lemon juice, and 1 teaspoon Creole Cajun seasoning. Stir well, cover, and refrigerate until serving.
- Marinate the catfish: Place catfish pieces in a large resealable bag or container. Add buttermilk, 1 teaspoon Cajun seasoning, 1 teaspoon Old Bay seasoning, and ground mustard. Toss to coat evenly, seal, and refrigerate for at least 2 hours or overnight for best flavor.
- Prepare the dredge: In a shallow dish, mix together flour, cornmeal, cornstarch, 1 teaspoon Cajun seasoning, and 1 teaspoon Old Bay seasoning.
- Heat the oil: In a heavy pot or Dutch oven, pour in enough oil to deep fry and heat to 350°F (use a thermometer for accuracy).
- Dredge the catfish: Remove catfish from marinade, shaking off excess liquid. Coat each piece thoroughly in the flour mixture, shaking off excess, and place on a wire rack or baking sheet without touching.
- Fry the catfish nuggets: Working in batches, carefully lower catfish pieces into hot oil. Fry for 2-3 minutes or until golden and crispy. Use a strainer to transfer to paper towels or a wire rack to drain.
- Rest and serve: Let the catfish rest for 5-7 minutes. Serve warm with the Cajun dipping sauce and lemon wedges.
Tips & Variations
- For extra crispiness, add a tablespoon of cornflakes crumbs to the dredging mix.
- If you can’t find Creole Cajun seasoning, a mix of paprika, garlic powder, onion powder, cayenne, and black pepper works well.
- Try swapping peanut oil for vegetable or canola oil if preferred, but keep the temperature steady for best frying results.
- Serve with additional hot sauce or tartar sauce for a flavor twist.
Storage
Store leftover catfish nuggets in an airtight container in the refrigerator for up to 2 days. Reheat them in a preheated oven at 375°F for 8-10 minutes to retain crispiness. Avoid microwaving to prevent sogginess.

FAQs
Can I use frozen catfish for this recipe?
Frozen catfish can be used, but thaw it completely and pat dry before marinating to ensure the coating sticks well and fries crisp.
What if I don’t have buttermilk?
You can make a buttermilk substitute by adding 1 tablespoon of lemon juice or white vinegar to ½ cup of milk. Let it sit for 5 minutes before using.

- 1 ½ lbs catfish fillets (about 4 fillets), cut into nugget-sized pieces
- ½ cup buttermilk
- 2 teaspoons Creole Cajun Seasoning, divided
- 2 teaspoons Old Bay seasoning, divided
- ½ teaspoon ground mustard
- ½ cup all-purpose flour

Cajun Dipping Sauce
- ½ cup full-fat mayonnaise (Duke’s recommended)
- ¼ cup ketchup
- 1 tablespoon garlic paste
- 1 tablespoon lemon juice
- 1 teaspoon Creole Cajun Seasoning
Instructions
- Prep the Cajun dipping sauce: In a small bowl, combine mayonnaise, ketchup, garlic paste, lemon juice, and Cajun seasoning. Stir thoroughly, cover, and chill in the refrigerator until ready to serve.
- Marinate the catfish: Place catfish pieces in a resealable bag or container. Add buttermilk, 1 tsp Cajun seasoning, 1 tsp Old Bay seasoning, and ground mustard. Toss to coat evenly, seal, and refrigerate for at least 2 hours or preferably overnight to tenderize and infuse flavor.
- Prepare for frying: Remove catfish from the fridge and let sit at room temperature briefly while preparing the dredging mixture and heating oil.
- Make the flour dredge: In a shallow dish, whisk together flour, cornmeal, cornstarch, 1 tsp Cajun seasoning, and 1 tsp Old Bay seasoning until well combined.
- Heat the oil: Pour a few inches of oil into a heavy-bottomed dutch oven or cast-iron pot. Heat over medium until the oil reaches 350°F (use a deep-fry thermometer for accuracy).
- Dredge the catfish pieces: Remove each catfish piece from the buttermilk, shake off excess liquid, then thoroughly coat in the seasoned flour mixture, ensuring all surfaces are covered. Place coated pieces on a wire rack set on a baking sheet, spaced apart to prevent sticking.
- Deep-fry the catfish: Working in batches, carefully lower coated catfish nuggets into hot oil. Fry for 2-3 minutes until golden brown and crispy. Use a spider strainer to transfer the nuggets to a paper towel-lined plate or a wire rack to drain excess oil. Maintain oil temperature at 350°F between batches.
- Rest and serve: Let the fried catfish nuggets rest for 5-7 minutes for optimal crispiness. Serve warm with the chilled Cajun dipping sauce and fresh lemon wedges on the side. Enjoy!

- Maintain the oil temperature at 350°F to ensure crispy, non-greasy nuggets.
- Use peanut oil or another high smoke point oil for best frying results.
- If you don’t have Creole Cajun seasoning, a mix of paprika, cayenne, garlic powder, onion powder, and dried herbs works well.
- Drain fried nuggets on a wire rack rather than paper towels for better crispness.
- Adjust frying time slightly if catfish nuggets are larger or smaller than usual.
