Ingredients List

For the Blackened Catfish:

  • 4 catfish fillets (6 oz each), patted completely dry
  • 3 tablespoons paprika (sweet or smoked for depth)
  • 2 teaspoons garlic powder
  • 2 teaspoons onion powder
  • 2 teaspoons dried oregano
  • 2 teaspoons dried thyme
  • 1½ teaspoons cayenne pepper (adjust to taste preference)
  • 1½ teaspoons black pepper, freshly ground
  • 1½ teaspoons white pepper
  • 1 teaspoon salt (preferably sea salt)
  • ½ teaspoon ground cumin
  • 6 tablespoons unsalted butter, melted

For the Remoulade Sauce:

  • ¾ cup mayonnaise (or Greek yogurt for lighter option)
  • 2 tablespoons Creole mustard (substitute: whole grain Dijon)
  • 2 tablespoons fresh lemon juice
  • 1 tablespoon capers, finely chopped
  • 2 green onions, finely minced
  • 2 cloves garlic, minced
  • 1 tablespoon fresh parsley, chopped
  • 1 teaspoon hot sauce (Crystal or Tabasco preferred)
  • ½ teaspoon Worcestershire sauce
  • ¼ teaspoon smoked paprika

Substitution Notes: Redfish or red snapper work beautifully as catfish alternatives, while those avoiding dairy can use olive oil instead of butter for basting.

Step-by-Step Instructions

Prepare the Spice Blend

Begin by combining all dry spices in a shallow dish, whisking thoroughly to ensure even distribution. The aromatic blend should release its fragrance immediately – this indicates fresh, potent spices that will deliver maximum flavor impact. Store any leftover spice mixture in an airtight container for up to three months.

Create the Remoulade Sauce

Whisk together mayonnaise, Creole mustard, and lemon juice until smooth and creamy. Fold in capers, green onions, garlic, parsley, hot sauce, Worcestershire, and smoked paprika. The sauce should have a pale pink hue with visible herb flecks. Refrigerate while preparing the fish – this resting time allows flavors to meld beautifully.

Prepare the Catfish

Pat catfish fillets completely dry using paper towels – moisture is the enemy of proper blackening. Brush both sides generously with melted butter, ensuring every surface is coated. The butter serves as both a flavor carrier and helps the spice mixture adhere properly.

Season the Fish

Dredge each buttered fillet in the spice mixture, pressing gently to ensure complete coverage. The fish should be thoroughly coated but not overly thick – you want seasoning, not breading. Allow seasoned fillets to rest for 5 minutes while your pan heats.

Heat the Cooking Surface

Preheat a cast-iron skillet or heavy-bottomed pan over medium-high heat until it’s smoking hot – approximately 4-5 minutes. The pan temperature should reach around 400°F for optimal blackening. A properly heated pan creates the signature crust while preventing sticking.

Blacken the Catfish

Carefully place fillets in the hot pan without overcrowding. Cook for 3-4 minutes without moving – resist the temptation to peek! The fish will release naturally when properly seared. Flip once and cook an additional 3-4 minutes until the internal temperature reaches 145°F.

Rest and Serve

Remove fillets from heat and let rest for 2 minutes. This brief resting period allows juices to redistribute, ensuring moist, flaky fish. Serve immediately with a generous dollop of remoulade sauce.

Catfish provides exceptional nutritional value, delivering 70% of your daily protein needs while remaining relatively low in calories. The omega-3 fatty acids support heart health, while the B-vitamin complex aids energy metabolism. Research indicates that the spice blend contributes significant antioxidants, particularly from paprika and oregano.

Healthier Alternatives for the Recipe

Reduce Calories: Substitute Greek yogurt for mayonnaise in the remoulade, cutting calories by 35% while adding probiotics and extra protein. Use cooking spray instead of butter for a 60-calorie reduction per serving.

Lower Sodium: Create a salt-free spice blend using additional herbs like basil, rosemary, and sage. Lemon zest adds brightness without sodium, while smoked paprika provides depth typically achieved through salt.

Heart-Healthy Option: Replace butter with heart-healthy olive oil or avocado oil. These substitutions maintain the cooking properties while providing beneficial monounsaturated fats.

Gluten-Free Assurance: This recipe is naturally gluten-free, making it perfect for those with celiac disease or gluten sensitivity.

Serving Suggestions

Elevate your blackened catfish presentation with these creative pairings that complement the bold Cajun flavors. Serve over creamy stone-ground grits with sautéed collard greens for an authentic Southern experience, or pair with coconut rice and black bean salad for a Caribbean twist.

For lighter options, present the fish atop mixed greens with cherry tomatoes and avocado slices, drizzling the remoulade as a tangy dressing. The dish pairs beautifully with roasted sweet potato wedges or cajun-spiced corn on the cob.

Wine enthusiasts should consider a crisp Sauvignon Blanc or dry Riesling to balance the heat, while beer lovers will appreciate a cold wheat beer or light lager. For non-alcoholic options, fresh lemonade with mint provides a refreshing counterpoint to the spicy fish.

Common Mistakes to Avoid

Wet Fish Syndrome: The most critical error is insufficient drying. Even slightly damp fish will steam rather than blacken, resulting in soggy, unappealing results. Pat fillets dry multiple times if necessary.

Temperature Troubles: Cooking over insufficient heat prevents proper crust formation, while excessive heat burns spices before cooking the fish. Medium-high heat with a properly preheated pan ensures success.

Spice Overload: Over-seasoning creates a gritty texture and overwhelming heat. A thin, even coating provides optimal flavor without masking the fish’s natural taste.

Timing Mistakes: Moving fish too early breaks the developing crust. Trust the process – properly seared fish releases naturally when ready to flip.

Storing Tips for the Recipe

Fresh Fish Storage: Use catfish within 24 hours of purchase for optimal quality. Store in the coldest part of your refrigerator (typically the bottom shelf) wrapped in paper towels and plastic wrap.

Cooked Leftovers: Refrigerate cooked catfish for up to 3 days in airtight containers. Reheat gently in a 300°F oven to maintain texture – microwaving often results in rubbery fish.

Remoulade Longevity: The sauce improves with time and keeps refrigerated for up to one week. The flavors continue developing, making day-old remoulade even more delicious.

Spice Blend Storage: Store the dry spice mixture in an airtight container away from light and heat. Properly stored, it maintains potency for 6 months, though flavors are strongest within the first 3 months.

FAQs

Q: Can I use frozen catfish fillets for this recipe? A: Yes, but ensure complete thawing and thorough drying. Frozen fillets often retain excess moisture, requiring additional drying time for optimal blackening results.

Q: What’s the difference between blackened and pan-fried catfish? A: Blackened fish uses high heat and heavy seasoning to create a distinctive crust, while pan-fried typically uses lower temperatures and lighter seasoning, often with flour coating.

Q: How spicy is this recipe, and can I adjust the heat level? A: The heat level is moderately spicy. Reduce cayenne pepper by half for mild heat, or eliminate it entirely for a family-friendly version that retains all other flavors.

Q: Can I make the remoulade sauce ahead of time? A: Absolutely! The sauce actually improves when made 4-24 hours ahead, allowing flavors to meld. It keeps refrigerated for up to one week.

Q: What other fish work well with this blackening technique? A: Red snapper, redfish, mahi-mahi, and salmon all blacken beautifully. Adjust cooking times based on thickness – thicker fillets require additional time per side.

Q: Is it normal for my kitchen to get smoky during blackening? A: Yes, some smoke is expected due to the high heat and spices. Ensure good ventilation and consider using an outdoor burner for heavy blackening sessions.
