📝 About This Recipe

Transport your senses to the vibrant streets of New Orleans with this quintessential Southern classic, featuring succulent prawns fried to a golden, shatter-crisp perfection. Our version honors the 'peacemaker' tradition, layering cornmeal-crusted seafood onto crusty French bread slathered with a piquant, house-made Cajun remoulade. It is a harmonious marriage of textures—crunchy, creamy, and soft—that captures the soulful essence of Louisiana's rich culinary heritage.

🥗 Ingredients

The Prawns & Marinade

  • 1.5 pounds Large Prawns (peeled, deveined, and tails removed)
  • 1 cup Buttermilk (full fat preferred)
  • 1 tablespoon Hot Sauce (Louisiana-style like Crystal or Tabasco)
  • 1 teaspoon Cajun Seasoning (low sodium)

The Crispy Coating

  • 1 cup All-purpose Flour
  • 1/2 cup Yellow Cornmeal (fine grind for better adhesion)
  • 2 tablespoons Cajun Seasoning (divided)
  • 1 teaspoon Smoked Paprika
  • 1 quart Vegetable Oil (for frying)

Spicy Remoulade Sauce

  • 1/2 cup Mayonnaise (high quality)
  • 2 tablespoons Creole Mustard (or whole grain Dijon)
  • 1 teaspoon Prepared Horseradish (drained)
  • 1 clove Garlic (minced into a paste)
  • 1 tablespoon Lemon Juice (freshly squeezed)

Assembly

  • 2 pieces French Bread Loaves (12-inch long, soft interior with crusty exterior)
  • 2 cups Shredded Iceberg Lettuce (finely shredded)
  • 2 pieces Vine-ripened Tomatoes (thinly sliced)
  • 12-16 slices Dill Pickle Chips
  • 2 tablespoons Unsalted Butter (melted, for toasting bread)

👨‍🍳 Instructions

  1. 1

    In a medium bowl, whisk together the buttermilk, hot sauce, and 1 teaspoon of Cajun seasoning. Add the cleaned prawns, toss to coat, and refrigerate for 20-30 minutes while you prepare the other components.

  2. 2

    Prepare the remoulade by combining mayonnaise, Creole mustard, horseradish, minced garlic, lemon juice, and a pinch of Cajun seasoning in a small bowl. Whisk until smooth, cover, and chill to let the flavors marry.

  3. 3

    In a shallow dish or large heavy-duty Ziploc bag, combine the flour, cornmeal, smoked paprika, and the remaining 2 tablespoons of Cajun seasoning. Mix thoroughly.

  4. 4

    Pour the vegetable oil into a deep cast-iron skillet or Dutch oven. Heat over medium-high heat until it reaches 360°F (182°C) on a deep-fry thermometer.

  5. 5

    While the oil heats, remove the prawns from the buttermilk a few at a time, letting excess drip off. Dredge them in the flour-cornmeal mixture, pressing gently so the coating adheres.

  6. 6

    Place the coated prawns on a wire rack for 5 minutes before frying. This 'setting' period prevents the breading from falling off in the hot oil.

  7. 7

    Fry the prawns in batches to avoid overcrowding the pan, which drops the oil temperature. Cook for 2-3 minutes per side until they are deep golden brown and curled.

  8. 8

    Use a slotted spoon to transfer the hot prawns to a paper-towel-lined plate or a clean wire rack. Immediately sprinkle with a tiny pinch of salt while the oil is still wet.

  9. 9

    Slice your French bread loaves lengthwise, but don't cut all the way through—leave a 'hinge' on one side. Brush the insides with melted butter.

  10. 10

    Toast the bread in a dry skillet or under a broiler for 1-2 minutes until the edges are golden and the bread is warmed through.

  11. 11

    Generously slather both the top and bottom insides of the bread with the chilled remoulade sauce.

  12. 12

    Layer the bottom of the sandwich with a thick bed of shredded iceberg lettuce, followed by 3-4 slices of tomato and 4-5 pickle chips.

  13. 13

    Pile the hot, crispy prawns high onto the dressed bread. Close the sandwich and press down slightly to meld the flavors.

  14. 14

    Slice each 12-inch loaf in half diagonally and serve immediately while the prawns are still piping hot.

💡 Chef's Tips

Don't skip the cornmeal; it provides the signature 'grit' and crunch that flour alone cannot achieve. Always use a thermometer to track your oil temperature; if it's too cold, the prawns will be greasy; if too hot, the breading will burn before the prawns cook. For the most authentic experience, look for 'Leidenheimer' style French bread, which has a very thin, crackly crust and an airy center. If you want extra heat, add a pinch of cayenne pepper to the flour dredge or double the hot sauce in the buttermilk. To keep the prawns warm while frying in batches, place the finished ones on a rack in a 200°F (95°C) oven.

🍽️ Serving Suggestions

Serve with a side of Zapp's Voodoo potato chips for a true New Orleans lunch experience. Pair with a cold Abita Amber lager or a crisp, citrusy pilsner to cut through the richness. A side of creamy southern-style coleslaw or pickled okra adds a nice acidic contrast. Offer extra hot sauce and lemon wedges on the side for guests to customize their spice and acid levels.
