French Quarter Po’ Boy with Crispy Shrimp

A French Quarter po’ boy is a New Orleans-style sandwich built with crisp fried shrimp, soft-crusted French bread, lettuce, tomato, pickles, and tangy remoulade. This home version keeps the shrimp crunchy and the toppings cool, with a practical frying method that delivers the contrast the sandwich is known for.

Ingredients

1 lb (450 g) large raw shrimp, peeled and deveined, tails removed
1 cup (240 ml) buttermilk
1 tsp (5 g) hot sauce, plus more to serve
1 cup (125 g) all-purpose flour
1 cup (120 g) fine yellow cornmeal
1 tsp (3 g) paprika
1 tsp (3 g) garlic powder
½ tsp (1 g) cayenne pepper, or less to taste
1 tsp (6 g) fine salt, divided
½ tsp (1 g) black pepper
About 4 cups (950 ml) neutral oil, such as canola or peanut oil, for frying; use enough for a depth of 1½ inches (4 cm)
½ cup (120 g) mayonnaise
1 tbsp (15 ml) Creole mustard; Dijon mustard is a practical substitute, with a slightly less spicy, less distinctly Louisiana flavor
1 tbsp (15 ml) lemon juice
1 tsp (5 ml) Worcestershire sauce
1 tsp (5 ml) hot sauce, or to taste
1 tbsp (10 g) finely chopped dill pickle
4 French-style sandwich rolls, about 8 inches (20 cm) long each (roughly 12 oz/340 g total); New Orleans French bread is traditional, but choose rolls with a tender interior and light crust
2 cups (90 g) shredded iceberg lettuce
1 medium tomato, about 6 oz (170 g), thinly sliced
½ cup (70 g) thinly sliced dill pickle chips
1 lemon, cut into wedges, for serving

Instructions

Make the remoulade. In a small bowl, stir together the mayonnaise, Creole mustard, lemon juice, Worcestershire sauce, hot sauce, chopped pickle, and a pinch of the measured salt. Cover and refrigerate while you prepare the shrimp. This brief rest lets the flavors blend; the sauce can also be made a day ahead.
Season and soak the shrimp. Pat the shrimp dry. In a medium bowl, mix the buttermilk with 1 teaspoon (5 ml) hot sauce. Add the shrimp and turn to coat. Let them stand for 10 minutes while you prepare the coating and toppings. Do not leave raw shrimp at room temperature longer than necessary; if your kitchen is warm or you need to wait longer, refrigerate them.
Set up the coating and bread. In a shallow dish, combine the flour, cornmeal, paprika, garlic powder, cayenne, remaining salt, and black pepper. Arrange the lettuce, tomato, and pickle slices. Split the rolls lengthwise without cutting all the way through, if you prefer them to hinge open, and warm them briefly in a low oven or dry skillet. Avoid making them crisp or hard.
Heat the oil. Pour oil into a heavy Dutch oven or deep, sturdy pot to a depth of about 1½ inches (4 cm), leaving ample space above it. Heat to 350°F (175°C), checking with a clip-on or instant-read thermometer. Keep the pot on a stable burner and never leave hot oil unattended. Set a wire rack over a tray for draining; paper towels can soften the crust.
Coat and fry in batches. Lift a few shrimp from the buttermilk, letting excess drip off, then dredge them in the flour-cornmeal mixture. Press the coating on lightly and shake off loose excess. Carefully lower shrimp into the oil in a single layer; do not crowd the pot. Fry for about 2–3 minutes, turning once if needed, until golden and opaque. Check the thickest shrimp with a food thermometer: the USDA FSIS safe minimum for fish and shellfish is 145°F (63°C). Transfer to the rack and let the oil return to 350°F (175°C) before frying the next batch. Cooking time varies with shrimp size and oil temperature.
Build the sandwiches. Spread remoulade generously inside each warm roll. Add lettuce, tomato, pickle slices, and hot shrimp. Serve right away with lemon wedges and extra hot sauce. Keep the shrimp in a loose layer rather than stacking them deeply, so their coating stays crisp.

Tips

Use a thermometer for the oil: too cool makes the coating greasy, while excessively hot oil browns the outside before the shrimp are properly cooked.
Fry in small batches and allow the oil to recover between them. Crowding lowers the temperature and can make the cornmeal coating soggy.
If you cannot find Creole mustard, Dijon works well. For a closer Louisiana-style kick, add a small extra dash of hot sauce rather than increasing the salt.
Dry the shrimp before they go into the buttermilk and shake off excess liquid before dredging. A wet, thick coating is more likely to fall off during frying.

Serving Suggestions

Serve the sandwiches as soon as they are assembled, alongside French fries, potato chips, or a simple cabbage slaw. A vinegary slaw is especially good with the rich remoulade and fried coating. Offer lemon wedges, extra pickle chips, and hot sauce at the table so everyone can adjust the sharpness and heat. If serving a group, put out the rolls and cold toppings separately, then fry the shrimp close to mealtime; this prevents assembled sandwiches from becoming damp.

Variations

For an oyster po’ boy, substitute shucked oysters for the shrimp and fry them until crisp and cooked through, checking that they reach 145°F (63°C). Use similarly sized oysters and avoid overcrowding the pot. For a catfish version, use 1 lb (450 g) catfish fillets cut into sandwich-size strips; fry until the centers reach 145°F (63°C). A non-seafood option is sliced green tomato or eggplant, coated and fried until tender and golden; this changes the classic seafood filling but keeps the crunchy, saucy sandwich format. You can also make the sandwich “dressed” in the New Orleans style by including lettuce, tomato, and pickle, or add thinly sliced onion if you like a sharper bite.

Storage and Reheating

For best texture, store shrimp, sauce, and toppings separately from the bread. Refrigerate cooked shrimp within 2 hours, in a covered shallow container, and use within 3–4 days. Keep the remoulade covered and refrigerated; use it within 3–4 days, or follow the use-by date of its mayonnaise. Do not store a fully assembled sandwich if you can avoid it, because the bread and coating soften.

Reheat shrimp in a single layer on a rack in a 375°F (190°C) oven or air fryer until hot and crisp, checking that leftovers reach 165°F (74°C). Timing depends on the appliance and shrimp size; begin checking after 5 minutes and avoid prolonged heating, which can make shrimp tough. Do not reheat shrimp more than once. Discard any perishable food left at room temperature for over 2 hours, or over 1 hour when the temperature is above 90°F (32°C).

Frequently Asked Questions

What does “dressed” mean on a po’ boy?
“Dressed” generally means the sandwich includes lettuce, tomato, and pickles, often with mayonnaise or another sauce. This recipe uses those toppings with remoulade; local preferences and shop versions vary.

What bread should I use for a French Quarter po’ boy?
Look for a long French-style roll with a tender, airy center and a relatively light crust. Traditional New Orleans French bread is ideal, but a sturdy sub roll is a workable substitute. Avoid very crusty bread that can crack or overpower the filling.

Can I use frozen shrimp?
Yes. Thaw them safely in the refrigerator overnight, or in a sealed bag submerged in cold water, changing the water every 30 minutes. Pat them dry before soaking in buttermilk. Do not thaw seafood on the counter.

Can I make the remoulade ahead?
Yes. Mix it up to a day in advance, cover, and refrigerate. Stir before serving. Keep it chilled while handling the shrimp, and use a clean spoon rather than one that has touched raw seafood.

Can I make this without a deep fryer?
Yes. A heavy pot with a thermometer works well; the oil should be deep enough for the shrimp to fry freely, but the pot must not be filled more than halfway. Fry in batches and keep children and pets away from the hot oil.

Why is my fried shrimp coating falling off?
Common causes are excess buttermilk, loose coating, or moving the shrimp too soon. Let excess liquid drip away, press the dredge gently onto each shrimp, shake off loose flour, and lower them carefully into properly heated oil. Leave them undisturbed briefly so the crust can set.
