Classic Louisiana Po Boy

Featured in: Everyday Meal Ideas

This beloved Louisiana classic features golden, crispy fried shrimp piled high on soft French rolls. The shrimp get their signature crunch from a cornmeal and flour coating seasoned with Cajun spices, paprika, and garlic powder. Each sandwich is layered with crisp shredded lettuce, ripe tomato slices, and a generous spread of creamy mayonnaise mixed with optional hot sauce.

The key to perfection lies in the frying temperature—350°F ensures the shrimp cook through while achieving that irresistible golden exterior. The soft French roll provides the perfect foundation, its slight char and pillowy interior balancing the crispy coating. Fresh lemon wedges on the side add brightness, while pickle slices offer a tangy contrast to the rich, fried seafood.

Ready in just 35 minutes, this sandwich serves four and brings authentic Louisiana flavor to your table. Pair with kettle chips or fries for the complete experience.

The first time I bit into a proper shrimp po' boy in New Orleans, I understood why people treat these sandwiches with reverence. It was pouring rain at a corner stand, and I watched a woman in her seventies hand-bread each shrimp while telling me about her grandchildren. The crunch through that first bite, followed by the cool lettuce and the heat from her house-made remoulade, made the rain feel like part of the experience. Now every time I make these at home, I remember that afternoon.

Last summer, I made a batch for my brother's birthday cookout and accidentally tripled the Cajun seasoning. Everyone was sweating and fanning their mouths, but they kept coming back for more. He still talks about that afternoon whenever shrimp is on the menu, though he does ask me to dial back the heat now.

Ingredients

  • Large shrimp: Fresh shrimp taste noticeably better than frozen, and buying them already peeled saves precious prep time
  • Cornmeal: Fine yellow cornmeal creates that signature crunch that Louisiana sandwiches are famous for
  • Buttermilk: The tang works beautifully with the shrimp while helping the flour-cornmeal coating cling perfectly
  • Soft French rolls: Day-old bread actually works better since it holds up to the generous fillings without falling apart
  • Iceberg lettuce: This traditional choice adds an essential cool crunch that contrasts with the hot fried shrimp

Instructions

Get your station ready:
Pat the shrimp completely dry with paper towels, then whisk together your eggs and buttermilk in one shallow bowl while combining the flour, cornmeal, and all the seasonings in another.
Coat the shrimp:
Working in batches, dip each shrimp into the buttermilk mixture letting the excess drip off, then press them firmly into the flour-cornmeal blend until evenly coated.
Heat the oil:
Pour about two inches of vegetable oil into a deep skillet or Dutch oven and bring it to 350°F, using a kitchen thermometer if you have one since the temperature really matters here.
Fry until golden:
Cook the shrimp in small batches for 2 to 3 minutes until they're golden brown and curled slightly, then transfer them to a paper towel-lined plate to drain.
Build your po' boy:
Slice the French rolls most of the way through, mix your mayo with hot sauce if you like some heat, then spread it generously before layering on lettuce, tomatoes, and those beautiful crispy shrimp.

These sandwiches became my go-to for summer nights when nobody wants to eat inside but everyone wants something substantial. There's something about standing around the kitchen island, eating shrimp po' boys with juice running down your wrists, that turns dinner into an event.

Make Ahead Magic

You can bread the shrimp up to 4 hours ahead and keep them refrigerated on a parchment-lined baking sheet, then fry them just before serving. The coating actually adheres better after that brief chill in the refrigerator.

Sauce Swaps

While mayonnaise mixed with hot sauce is classic, I've fallen in love with mixing in a tablespoon of Creole mustard or trading the whole situation for a quick homemade remoulade. My neighbor swears by adding a splash of pickle juice to her mayo for extra tang.

The Perfect Sides

A shrimp po' boy practically demands something salty and crunchy alongside it to complete the experience.

  • Kettle-cooked potato chips add the perfect saltiness
  • Cold potato salad balances the hot fried shrimp
  • Serve extra lemon wedges for those who love that bright finish

Recipe FAQs

What makes a Po Boy sandwich authentic?

A traditional Po Boy uses crispy fried seafood or meat on French bread with crisp lettuce, tomatoes, and mayonnaise. The bread should be soft with a thin, crispy crust, and the fried shrimp should have a light cornmeal coating for that signature Louisiana crunch.

Can I bake the shrimp instead of frying?

Yes, for a lighter version, arrange the coated shrimp on a baking sheet and bake at 400°F for 12-15 minutes, flipping halfway through. The texture will be slightly different but still delicious.

What's the best oil temperature for frying shrimp?

Maintain your oil at 350°F (175°C) for optimal results. This temperature ensures the coating crisps quickly while the shrimp cook through without becoming rubbery. Use a kitchen thermometer for accuracy.

What can I substitute for buttermilk?

Mix regular milk with 1 tablespoon of white vinegar or lemon juice and let it sit for 5 minutes. This DIY buttermilk alternative works perfectly for the egg wash and helps the coating adhere.

How do I keep the shrimp crispy when assembling?

Fry the shrimp last and drain them well on paper towels. Assemble the sandwiches just before serving and avoid placing hot shrimp directly on the mayonnaise, which can make the coating soggy. A quick toast on the cut side of the rolls also helps.
