Instructions

  1. Step 1: Preheat a large cast iron skillet over medium-high heat. Pat dry 4 catfish fillets and evenly coat both sides with 2 tbsp blackening seasoning.
  2. Step 2: Add 3 tbsp olive oil to the hot skillet and place catfish fillets in the pan. Cook for 4 minutes per side until the exterior is deeply browned and fish flakes easily.
  3. Step 3: In a small bowl, combine 1/2 cup mayonnaise, 1 tbsp Dijon mustard, 1 tbsp chopped capers, 1 tbsp lemon juice, 1 tsp hot sauce, 1/2 tsp garlic powder, and 1/2 tsp paprika. Mix thoroughly to create the remoulade aioli.
  4. Step 4: Slice 4 French rolls lengthwise without cutting all the way through. Spread 2 tbsp remoulade aioli inside each roll.
  5. Step 5: Layer 2 romaine lettuce leaves and 2-3 slices of tomato per sandwich, then top with the blackened catfish fillets.
  6. Step 6: Close sandwiches and serve immediately, enjoying the contrast of spicy fish and tangy aioli.

How do I store leftover Blackened Catfish Po’Boy with Remoulade Aioli?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).
