Instructions

  1. Step 1: In a shallow bowl, combine 1 cup cornmeal, 1/2 cup all-purpose flour, 1 tsp paprika, 1/2 tsp garlic powder, 1/4 tsp cayenne pepper, 1 tsp salt, and 1/2 tsp black pepper. In another bowl, pour 1 cup buttermilk.
  2. Step 2: Dip each of the 4 catfish fillets into the buttermilk, allowing excess to drip off, then dredge thoroughly in the cornmeal mixture, pressing lightly to coat evenly.
  3. Step 3: Heat 2 cups vegetable oil in a deep skillet over medium-high heat to 350°F. Fry the coated catfish fillets for 4-5 minutes per side until golden brown and crispy. Remove and drain on paper towels.
  4. Step 4: For remoulade sauce, whisk together 1/2 cup mayonnaise, 1 tbsp Dijon mustard, 2 tbsp chopped capers, 2 tbsp pickle relish, 1 tbsp lemon juice, 1 tsp Worcestershire sauce, and 1 tsp hot sauce until smooth.
  5. Step 5: Slice 4 French baguette rolls lengthwise without cutting all the way through. Spread a generous layer of remoulade sauce inside each roll.
  6. Step 6: Layer 2 leaves of lettuce and 2-3 tomato slices in each roll, then place one fried catfish fillet inside. Serve immediately to enjoy the crisp textures.

Frequently asked questions

Total time is about 35 minutes (20 min prep + 15 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Po’Boy with Fried Catfish and Remoulade Sauce?

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