Authentic Louisiana Blackened Cajun Catfish: An Arteflame Grill Special

There is a distinct magic found in the culinary traditions of the Bayou, where heat meets flavor in a spectacular display of technique. Blackened Cajun Catfish is not merely a recipe; it is an experience that engages all the senses, characterized by the aromatic explosion of spices hitting smoking hot steel. This cooking method, made famous by Chef Paul Prudhomme, relies heavily on high, intense heat to carbonize the spices and butter into a savory, crispy crust while keeping the fish inside moist and flaky. There is no better tool for this than the Arteflame grill, which provides the perfect searing surface to replicate authentic Louisiana restaurant quality right in your backyard. By utilizing the center cooktop's intense heat, you achieve that signature dark crust without overcooking the delicate flesh. This dish is fast, furious, and incredibly flavorful, making it a perfect choice for outdoor entertaining where you want to impress guests with both the spectacle of cooking and the depth of flavor.

Ingredients

The Fish and Coating

• 4 Catfish fillets (6-8 ounces each), fresh and pat dry
• 1 stick Unsalted butter, melted (for dipping)
• Lemon wedges (for garnish and serving)
• Fresh parsley, chopped (optional garnish)

The Homemade Cajun Blackening Rub

• 1 tablespoon Sweet Paprika
• 2 teaspoons Onion Powder
• 1 teaspoon Garlic Powder
• 1 teaspoon Cayenne Pepper (adjust for heat)
• 1 teaspoon White Pepper
• 1 teaspoon Black Pepper
• 1/2 teaspoon Dried Thyme
• 1/2 teaspoon Dried Oregano
• 1 teaspoon Salt

Instructions

Step 1: Fire Up the Grill

1. Start your Arteflame grill by building a medium-sized fire in the center. Allow the fire to burn down until the center cooktop reaches a very high searing temperature (over 400°F).
2. Scrape the cooktop clean to ensure a pristine searing surface. Apply a very thin layer of high-smoke point oil (like grapeseed) to the steel to season it just before cooking.

Step 2: Prepare the Spice Blend

1. In a small bowl, combine the paprika, onion powder, garlic powder, cayenne, white pepper, black pepper, thyme, oregano, and salt.
2. Mix thoroughly with a fork or small whisk to ensure the spices are evenly distributed. This balance is crucial so no single bite is too salty or too spicy.
3. Pour the spice blend onto a large, flat plate or a shallow baking dish for easy dredging.

Step 3: Coat the Catfish

1. Pour the melted butter into a separate shallow dish.
2. Take a catfish fillet and dip it entirely into the melted butter, ensuring both sides are well-coated.
3. Immediately lay the buttered fillet onto the plate of spices. Press down firmly, then flip and coat the other side. You want a heavy, even coating of spices—this is what forms the black crust.

Step 4: The Sear

1. Place the fillets directly onto the hottest part of the Arteflame cooktop (near the center, but not directly over the open flame opening to avoid flare-ups).
2. Let the fish cook undisturbed for 2 to 3 minutes. Do not move it. You are looking for the spices to char and darken significantly.
3. Carefully flip the fish. Pour a teaspoon of the remaining melted butter over the cooked side for extra richness. Cook for another 2 to 3 minutes until the underside is crisp and the fish flakes easily with a fork.

Step 5: Rest and Serve

1. Remove the catfish from the grill and let it rest for a minute to allow the juices to redistribute.
2. Squeeze fresh lemon juice over the top immediately to cut through the richness of the spices and butter.
3. Garnish with fresh parsley and serve hot directly from the grill.

Tips for the Perfect Sear

Mastering blackened fish on the Arteflame requires confidence in heat management. The most common mistake beginners make is fearing the smoke; however, true blackening creates a significant amount of smoke as the butter solids and spices char. This is normal and desirable. Ensure your grill surface is extremely hot before the fish touches it. If the grill isn't hot enough, the spices will steam rather than sear, and you will lose that signature crisp texture. Additionally, when dipping the fish, move quickly between the butter and the spice mix so the butter doesn't solidify on the cold fish. If you find the fish sticking, it likely hasn't finished forming its crust yet—give it another thirty seconds. Finally, keep your butter warm but not boiling hot to prevent it from separating before you coat the fish. Always have a clean spatula ready for the flip to keep the fillet intact.

Variations

While catfish is the traditional choice for this Louisiana staple due to its firm texture and mild flavor, the blackening technique is incredibly versatile and can be adapted to various dietary preferences and tastes. You can easily swap the protein while keeping the same delicious spice profile. If you prefer a less earthy fish, Red Snapper or Grouper are excellent alternatives that hold up well to the high heat of the Arteflame. For a non-seafood option, this spice rub works wonders on thin chicken cutlets or pork chops. Here are a few creative ways to switch up this recipe:

• Blackened Redfish: Use Redfish fillets with the skin on for a sturdier grilling experience.
• Cajun Tacos: Flake the cooked fish into warm corn tortillas with cabbage slaw and lime crema.
• Creamy Cajun Pasta: Serve the whole fillet over fettuccine Alfredo to balance the heat with creamy richness.
• Surf and Turf: Serve a smaller blackened fillet alongside a grilled ribeye steak.
• Vegetarian Option: Use thick slices of eggplant or zucchini instead of fish, using oil instead of butter for the adhesive.

Best pairings

To create a balanced meal that respects the intensity of the blackened seasoning, your side dishes should either offer a cooling contrast or complement the rustic, savory nature of the Cajun spices. Traditional Southern sides are naturally the best fit, grounding the meal in its cultural roots. You want textures that absorb the juices and flavors that can stand up to the heat of the cayenne pepper without overpowering the fish. Since you already have the Arteflame fired up, consider cooking your vegetable sides on the outer, cooler ring of the cooktop while the fish sears in the center. This timing ensures everything hits the plate hot and ready. A cold beverage is also non-negotiable with this level of spice.

• Dirty Rice: A classic Louisiana side with ground meat and liver that adds savory depth.
• Corn Maque Choux: A creamy, sweet corn and pepper sauté that balances the spicy fish perfectly.
• Remoulade Sauce: A cool, creamy dipping sauce to dip bites of the hot fish into.
• Grilled Asparagus: Simple, charred veggies with lemon zest offer a light, fresh contrast.
• Ice Cold Lager: The crisp carbonation cuts through the butter and spice heat.
