Cajun Grilled Catfish (North Dakota Style) | Arteflame

Introduction

Imagine the sound of a sizzling sear and the aroma of smoky paprika drifting through the cool evening air. This North Dakota Style Cajun Grilled Catfish bridges the gap between rugged Northern catches and bold Southern soul. It’s the kind of meal that turns a quiet backyard dinner into a festive occasion, delivering a buttery, blackened crust that gives way to perfectly flaky, moist fish. Whether you are cooking a fresh catch or a store-bought fillet, the result is a smoky, spicy masterpiece.

Why This Recipe is a Keeper

I adore this recipe because it conquers the biggest fear of grilling fish: the meat falling apart. The solid carbon steel cooktop of the Arteflame ensures you get a restaurant-quality blackened sear without losing a single flake to the fire. It’s a fast, high-impact meal where the heat of the cayenne meets the cooling richness of fresh butter, creating a flavor profile that is utterly addictive.

Secrets for the Perfect Sear

• Pat it Dry: Moisture is the enemy of a crisp crust. Ensure your fillets are thoroughly dried with paper towels before seasoning to prevent steaming.
• Trust the Release: If the fish feels stuck when you try to flip, it’s not ready. Wait another minute; the proteins will release naturally from the steel once the sear is set.

Easy Swaps

If catfish isn't your preference, this method works beautifully with other firm white fish like Walleye or Tilapia. For those sensitive to heat, simply dial back the cayenne pepper in the rub and lean into the garlic and paprika for a savory, mild Creole version.

Ingredients

The Fish & Marinade

• 4 fresh Catfish fillets (approx. 6-8 oz each)
• 1/4 cup unsalted butter, melted
• 2 tablespoons olive oil (plus more for the grill surface)
• 1 fresh lemon, cut into wedges for serving
• 2 tablespoons fresh parsley, chopped (for garnish)

Homemade Cajun Seasoning Rub

• 1 tablespoon smoked paprika
• 2 teaspoons garlic powder
• 2 teaspoons onion powder
• 1 teaspoon dried oregano
• 1 teaspoon dried thyme
• 1 teaspoon cayenne pepper (adjust for heat)
• 1 teaspoon freshly ground black pepper
• 1 teaspoon sea salt

Instructions

Step 1: Fire Up the Arteflame

1. Begin by building a medium-sized fire in the center of your Arteflame grill using seasoning firewood or charcoal.
2. Allow the grill to heat up for about 15 to 20 minutes. You want the flat cooktop griddle to be hot, but not scorching. Aim for a medium-high heat zone, which is typically found near the middle of the ring, but not directly at the inner edge where the fire is hottest.
3. While the grill heats, wipe down the cooktop with a lightly oiled paper towel to ensure a slick, non-stick surface.

Step 2: Prepare the Catfish

1. Rinse the catfish fillets under cold water and pat them thoroughly dry with paper towels. Removing excess moisture is critical for getting a good sear rather than steaming the fish.
2. In a small bowl, mix the melted butter and olive oil together. Brush this mixture generously over both sides of the catfish fillets.
3. In a separate small bowl, combine all the dry spice ingredients (paprika, garlic, onion, oregano, thyme, cayenne, salt, and pepper) to create your rub.
4. Sprinkle the Cajun seasoning liberally over the fish, pressing it gently into the flesh to ensure it adheres.

Step 3: Grill the Fish

1. Apply a thin layer of oil directly onto the flat cooktop where you intend to place the fish.
2. Place the fillets on the hot griddle surface. You should hear an immediate, aggressive sizzle—this is the sound of the Cajun spices blackening and the crust forming.
3. Let the fish cook undisturbed for 3 to 4 minutes. Do not try to move it too early; once the crust forms, the fish will naturally release from the steel surface.

Step 4: Flip and Finish

1. Using a wide metal spatula, slide under the fillet and flip it over carefully. The cooked side should have a beautiful, dark mahogany or blackened color.
2. Cook the second side for another 3 to 4 minutes, depending on the thickness of the fillet.
3. The fish is done when the flesh is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C).

Step 5: Garnish and Serve

1. Remove the fillets from the grill and transfer them to a serving platter.
2. Squeeze fresh lemon juice over the hot fish immediately to brighten the flavors and cut through the spice.
3. Garnish with chopped fresh parsley and serve while piping hot.

Tips

Grilling fish requires a delicate balance of heat and timing, especially when working with a spice-heavy rub like Cajun seasoning. One of the most important tips for this recipe is to manage your heat zones on the Arteflame. Sugar and paprika in rubs can burn quickly if exposed to direct, searing flames for too long. Start grilling about three inches away from the inner ring to prevent the spices from turning bitter before the fish is cooked through. Additionally, always make sure your fish is completely dry before applying the butter and rub; moisture creates steam, which prevents that signature blackened crust from forming. Finally, trust the "release." If you try to flip the fish and it feels stuck to the griddle, it likely needs another 30 to 60 seconds. The proteins will release from the seasoned steel naturally once the sear is complete.

Variations

This North Dakota Cajun Grilled Catfish is a versatile dish that can be easily adapted to suit different palates or dietary preferences. If you find the heat of traditional Cajun spice too intense, you can create a "Creole" version by reducing the cayenne pepper and increasing the paprika and garlic powder for a savory, aromatic flavor without the burn. For a fresher, zesty twist, try a Lemon-Pepper variation by swapping the Cajun rub for cracked black pepper, lemon zest, and dried dill. If you want to change how you serve the fish, this recipe is fantastic for Catfish Po'Boys or Fish Tacos. Simply break the grilled fillets into large chunks and serve them on a toasted baguette with remoulade sauce, or in soft corn tortillas with a crunchy cabbage slaw and lime crema. You can also swap the catfish for other firm white fish like walleye or tilapia.

• Mild Creole: Less cayenne, more garlic and herbs.
• Lemon-Pepper: Zest, black pepper, dill, and salt.
• Catfish Po'Boy: Serve on French bread with lettuce, tomato, and remoulade.
• Fish Tacos: Flake into tortillas with slaw and cilantro-lime sauce.
• Garlic Butter: Skip the dry rub and baste with garlic-herb butter while grilling.

Best pairings

To balance the smoky heat of the Cajun spices, you need side dishes that offer cooling, creamy, or slightly sweet elements. The classic pairing for this dish is a creamy, vinegar-based coleslaw. The crunch of the cabbage and the tang of the dressing cut right through the richness of the butter and the heat of the cayenne. Grilled corn on the cob is another natural companion; since your Arteflame is already hot, you can roast the corn right alongside the fish, slathering it with chili-lime butter for a Mexican street corn vibe. Hush puppies or cornbread are essential starch pairings, providing a sweet, crumbly contrast to the tender fish. For beverages, an ice-cold pilsner or a light lager works wonders to refresh the palate, while a chilled glass of Sauvignon Blanc or a sweet iced tea complements the spicy profile perfectly.
