Ingredients

Instructions

  1. Step 1: In a shallow dish, mix 1 cup all-purpose flour, 1/2 cup cornstarch, 1 tablespoon paprika, 1 teaspoon garlic powder, 1 teaspoon salt, and 1/2 teaspoon black pepper. Dip 1 1/2 pounds catfish fillets in 1 cup buttermilk, then coat thoroughly in the flour mixture.
  2. Step 2: Heat 2 cups vegetable oil in a deep skillet over medium-high to 350°F (175°C). Fry the catfish in batches for 3-4 minutes per side until golden and crispy, then drain on paper towels.
  3. Step 3: Whisk 1/2 cup mayonnaise, 2 tablespoons chopped pickles, 1 tablespoon fresh parsley, 1 teaspoon Dijon mustard, 1/4 teaspoon cayenne pepper, 1/4 cup chopped celery, and 1/4 cup chopped red onion in a bowl until smooth.
  4. Step 4: Split 4 baguette buns and spread remoulade on the bottom halves. Place 3-4 fried catfish fillets on each bun, top with more remoulade, and close with the top halves.

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep pounds catfish fillets from drying out.

Can I substitute ingredients in Fried Catfish Sandwich with Remoulade?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Fried Catfish Sandwich with Remoulade for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
