Featured on Fish the Dish, this bold seafood sandwich combines Southern-inspired comfort food with fresh, zesty flavours for a satisfying and indulgent meal.

The Inspiration

This dish is inspired by the classic New Orleans po’ boy sandwich, traditionally made with fried seafood and served on a crusty baguette-style bread. Known for its crunchy texture and bold flavours, the po’ boy is a staple of Southern coastal cuisine.

On Fish the Dish, host Spencer Watts often reinterprets iconic regional dishes through a modern seafood lens. This recipe reflects that approach by pairing crispy fried oysters with a smoky chipotle mayonnaise and fresh slaw for balance and contrast.

Ingredients

Fried Oysters

• 2 cups (470 ml) pre-shucked oysters, drained (about 36)
• 2 eggs
• ¼ cup (60 ml) whole milk
• ½ cup (120 ml) cornmeal
• 1 cup (250 ml) flour
• 2 ½ teaspoon (12.5 ml) salt
• ¼ teaspoon (1.25 ml) Black pepper
• 6 cups (1.4 L) Vegetable oil for frying
• 1 baguette or ciabatta loaf

Chipotle Mayonnaise

• 4 egg yolks
• 2 tablespoons (30 ml) red wine vinegar
• 1 lemon, juice
• 1 tablespoon (15 ml) Dijon mustard
• 2 garlic cloves
• 1 shallot
• 2 tablespoons (30 ml) maple syrup
• 1 tablespoon (15 ml) canned chipotle pepper sauce
• 1 cup (240 ml) canola oil

Slaw

• 2 medium carrots, peeled and cut into matchsticks
• ¼ head napa cabbage, shredded
• ¼ head red cabbage, shredded
• 1 lemon, juice
• 6  tablespoons (90 ml) vegetable oil
• Salt and pepper

Methods

• Preheat the oven to 375°F (190°C).
• Slice open baguette but do not fully separate halves. Add oil and salt and bake in the oven 4 minutes, or until toasted.
• Heat a pot of oil to 375°F (190°C).
• Add egg yolks, red wine vinegar, lemon juice, Dijon, garlic, shallot, maple syrup, and canned chipotle pepper sauce to a blender. Drizzle in olive oil while blitzing; about 20 seconds.
• Whisk eggs and milk together in a bowl. In a separate bowl, combine cornmeal, flour, salt, and pepper.
• Use one hand to dunk the oysters in the egg wash, and the other hand to dredge in the dry ingredients.
• Fry coated oysters in the hot oil, turning occasionally, until golden and just cooked through, about 1-2 minutes. Use tongs to remove to a paper towel-lined plate to drain. Immediately season with salt.
• Place the cabbage and carrots in a bowl.  Squeeze in lemon juice. Drizzle in oil and toss.
• Spread chipotle mayonnaise in crispy baguette. Add the slaw and top with the fried oysters

Serving Suggestions

Serve with crispy fries, sweet potato wedges, or a simple green salad to complete the meal. Pickles or pickled vegetables also pair well, adding acidity to balance the richness of the fried oysters.

For beverage pairings, cold beer such as pilsner, lager, or pale ale works beautifully with the fried seafood and smoky chipotle heat. Sparkling lemonade or iced tea with citrus also provides a refreshing contrast.

This sandwich is best served immediately after frying while the oysters are hot and crispy and the bread is still warm and toasted.
