Ingredients List

• Cod Fillets: 4 thick cod fillets (about 1.5 lbs, cut into thick strips or portions, patted completely dry)

• Cajun Seasoning: 1.5 tablespoons (store-bought or a blend of paprika, garlic powder, onion powder, cayenne, thyme, and oregano)

• Olive Oil or Avocado Oil: 2 tablespoons (for searing)

• Unsalted Butter: 2 tablespoons (adds a rich, glossy finish)

• For the Homemade Tartar Sauce:

  • 1/2 cup mayonnaise

  • 1 tablespoon sweet pickle relish or finely diced dill pickles

  • 1 teaspoon fresh lemon juice

  • 1 teaspoon Dijon mustard

  • 1 tablespoon fresh parsley, finely chopped

  • Salt and black pepper to taste

Step-by-Step Cooking Instructions

1. Prepare the Tartar Sauce: In a small bowl, whisk together the mayonnaise, pickle relish, lemon juice, Dijon mustard, and chopped parsley. Season with a pinch of salt and pepper to taste. Cover and place in the refrigerator to let the flavors meld while you cook the fish.

2. Season the Cod: Pat the cod fillets thoroughly dry with paper towels (this is key for a good sear). Generously sprinkle the Cajun seasoning over all sides of the fish, pressing it gently into the flesh so it adheres well.

3. Heat the Skillet: Heat a large cast-iron skillet over medium-high heat. Add the olive oil and allow it to shimmer.

4. Sear the Fish: Carefully lay the seasoned cod fillets into the hot skillet. Cook undisturbed for about 3 to 4 minutes until a deep, smoky crust forms on the bottom.

5. Add Butter and Finish: Add the unsalted butter to the pan. As it melts, use a spoon to continuously baste the top of the cod fillets with the foaming, spiced butter. Gently flip the fish and cook for another 2 to 3 minutes until the cod is cooked through, opaque, and flakes easily with a fork.

6. Serve: Plate the seared Cajun cod immediately alongside a generous bowl of the chilled homemade tartar sauce and lemon wedges.

Frequently Asked Questions (High-CPM Keywords & Search Intent)

• How to get a crispy crust on seared cod without breading? To achieve a restaurant-style crust without flour or breadcrumbs, ensure your fish is completely dry before applying spices, use a smoking hot cast-iron skillet, and do not move the fish during the first few minutes of searing.

• Can I bake Cajun cod in the oven instead of pan-searing? Yes! You can bake the seasoned cod fillets at 200°C (400°F) for 12 to 15 minutes, or until the fish is opaque and flakes easily. Drizzle with melted butter halfway through for extra richness.

• What are the best side dishes to serve with Cajun fish? This dish pairs wonderfully with garlic butter asparagus, creamy cauliflower mash, roasted sweet potato wedges, or a crisp green garden salad.

• How to store and reheat leftover cooked cod? Store leftover cod in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over medium-low heat with a splash of water or broth to prevent the fish from drying out.

Chef’s Pro-Tip: If you prefer a milder heat profile, look for a “sweet Cajun” seasoning blend or mix a pinch of brown sugar into your spice rub to balance out the kick of the cayenne pepper!
