Pin it
One bite into this crunchy, saucy New Orleans Po' Boy and suddenly you'll understand why the bread matters as much as the shrimp. The crust should crackle a little, the inside should stay soft, and every bite should catch sauce, pickle, lettuce, and hot fried seafood.
This version is built for a home kitchen. The shrimp get a quick buttermilk soak, a seasoned flour and cornmeal coating, and a fast fry so they stay juicy under that crisp shell.
The Po' Boy Lineup
Good shrimp and the right bread do most of the work here. Choose peeled, deveined large shrimp and the lightest French rolls you can find, not a dense baguette that fights back when you bite it.
- Large shrimp. They fry quickly and stay sweet and juicy under the crunchy coating.
- Buttermilk. Helps season the shrimp and gives the dredge something to grip.
- Flour and cornmeal. Flour creates coverage while cornmeal adds the sandy crunch seafood Po' Boys need.
- Cajun seasoning. Brings paprika, garlic, pepper, and a little heat to the crust.
- Mayonnaise and Creole mustard. Make the creamy, sharp base for the remoulade.
- Pickles and lemon. Cut through the fried shrimp with acid and brightness.
- French rolls. Hold the sauce and shrimp without turning heavy or chewy.
- Lettuce and tomato. Give the sandwich its cool dressed crunch.
Fry, Dress, And Serve
- Mix the sauce. Stir the remoulade first so the mustard, lemon, hot sauce, and pickle can settle while you fry.
- Soak the shrimp. Toss the shrimp with buttermilk and hot sauce for 10 minutes. This seasons them lightly and helps the crust cling.
- Heat the oil. Bring 2 inches of oil to 350 F in a heavy pot. Set a wire rack over a sheet pan for draining.
- Dredge the shrimp. Lift shrimp from the buttermilk, shake off the extra, then coat well in the seasoned flour and cornmeal mixture.
- Fry in batches. Cook shrimp for 2-3 minutes until deep golden and crisp. Do not crowd the pot or the coating will turn greasy.
- Build the Po' Boys. Spread remoulade on both sides of the rolls, then add lettuce, tomato, pickles, and hot fried shrimp. Serve with lemon and more hot sauce.
Bread Carries The Sandwich
New Orleans Po' Boy bread is famous for a thin, crackly crust and an airy middle. That texture matters because the sandwich has wet sauce, juicy tomatoes, pickles, and fried shrimp. A dense baguette can make the whole thing feel dry, even with plenty of remoulade. A soft French roll, hoagie roll, or Cuban-style loaf is a better home substitute.
Food & Wine has a useful overview of why Po' Boys lean on flaky French bread and what dressed means in New Orleans. Their guide to Po' Boy styles and fillings is worth a read if you want to riff beyond shrimp.

Keep The Shrimp Crunchy
The coating is simple, but the oil temperature decides the texture. At 350 F, the shrimp cook fast and the crust sets before it soaks up oil. If the oil drops too low, the coating gets pale and heavy. If it runs too hot, the outside browns before the shrimp are done.
Fry in small batches and give the oil a minute to recover between rounds. A wire rack helps too. Paper towels trap steam underneath, which softens the crust right where you worked hardest to make it crisp. The FDA seafood guide recommends cooking shrimp until they are opaque and safe to eat, and seafood guidance is available from the FDA seafood safety page.
Remoulade Brings The Snap
A good Po' Boy sauce should be creamy, sharp, and a little spicy. Mayonnaise gives it body. Creole mustard brings bite. Pickle, lemon, horseradish, Worcestershire, and hot sauce keep it from tasting flat. If you like a looser sauce, add another squeeze of lemon right before spreading it on the bread.
This sauce is also where you can adjust the heat. Add cayenne for a slow burn or extra hot sauce for vinegar punch. If you are cooking a New Orleans-style meal, serve these sandwiches with Cajun New Orleans Shrimp and Creamy Grits for a shrimp-heavy spread, or start with a pot of Authentic New Orleans Creole Gumbo.
Smart Swaps That Work
No Creole mustard? Use whole-grain mustard with a pinch of paprika and cayenne. No cornmeal? Use all flour, but add 2 tablespoons of fine breadcrumbs for a little grit. You can also swap shrimp for thin catfish strips or oysters, keeping the same coating and fry temperature.
For a lighter sandwich, skip the deep pot and shallow-fry the shrimp in about 1/2 inch of oil, turning once. The crust will be a touch less even, but still good. Gluten-free rolls and a gluten-free flour blend can work for the bread and dredge, though this recipe as written is not gluten-free.

Make-Ahead And Leftovers
Po' Boys are best right after frying, but you can make the work easier. Mix the remoulade up to 4 days ahead. Slice the lettuce, tomatoes, and pickles earlier in the day and keep them cold. The shrimp can be peeled and seasoned, but wait to dredge until the oil is hot.
Leftover fried shrimp will soften in the fridge. Reheat them in a 375 F oven or air fryer for 5-8 minutes until hot and crisp at the edges. Do not microwave them unless you are fine with a softer crust. Store the bread separately and assemble only what you plan to eat.
FAQs
- What makes a sandwich a New Orleans Po' Boy?
A Po' Boy is usually served on light New Orleans-style French bread with a crisp crust and soft center. Fried seafood, roast beef, and hot sausage are classic fillings, and a dressed version usually includes lettuce, tomato, pickles, and mayo or sauce.
- Can I use frozen shrimp?
Yes. Thaw frozen shrimp in the refrigerator overnight or under cold running water, then pat them very dry. Extra surface moisture weakens the coating and cools the oil too fast.
- What can I use instead of buttermilk?
Use whole milk mixed with 1 tablespoon lemon juice or vinegar, then let it sit for 5 minutes. It will not be quite as thick as buttermilk, but it gives the shrimp enough tang and helps the coating cling.
- How do I keep the fried shrimp crispy?
Keep the oil near 350 F and fry in small batches. Drain the shrimp on a wire rack instead of paper towels so steam can escape from the bottom.
- Can I make the remoulade ahead?
Yes. Remoulade tastes better after 30 minutes in the fridge and keeps for about 4 days in a covered container. Stir it before serving because the pickle and lemon can loosen the sauce a little.
- How should I store leftover Po' Boy ingredients?
Store the shrimp, sauce, bread, and vegetables separately. Reheat shrimp in a 375 F oven or air fryer until hot and crisp, then assemble fresh sandwiches right before eating.
