Shrimp Po Boy Sandwich

My first po boy came from a tiny shop in New Orleans during a sweltering August, and I remember the confusion on my face when the owner insisted the sandwich was supposed to be messy. The crispy shrimp actually broke through the lettuce with a satisfying crunch, and somewhere between the oil-soft bread and that creamy mayo, I understood what she meant. Years later, I tried recreating it at home, and honestly, the version I make now tastes just as good as that street-side discovery, minus the sweat.

I made these for my brother's birthday picnic last spring, and watching everyone's faces light up when they bit through that crispy shell into tender shrimp made me realize this wasn't just lunch, it was the kind of simple meal people remember. He asked me for the recipe right there, with mayo on his chin, which felt like the highest compliment I could get.

Ingredients

• Large shrimp (1 lb): Look for shrimp that are firm and smell like the ocean, not ammonia; they should be the star of this sandwich.
• All-purpose flour (1 cup): This creates the base of your coating and helps the cornmeal stick properly.
• Cornmeal (1 cup): Here's where the real texture magic happens; cornmeal gives you that distinctive crispy crust that makes a po boy unmistakable.
• Eggs (2 large) and buttermilk (1/2 cup): Together they create the perfect sticky medium for your coating; buttermilk makes the shrimp tender inside.
• Cajun seasoning (1 tsp), paprika (1/2 tsp), garlic powder (1/2 tsp), salt (1/2 tsp), black pepper (1/4 tsp): Don't skip the Cajun seasoning; it's what gives this sandwich its Louisiana soul.
• Vegetable oil for frying: You need enough depth so the shrimp can swim freely; too shallow and they'll fry unevenly.
• French rolls or hoagie buns (4): Soft but sturdy enough to hold the filling without falling apart; stale bread is your enemy here.
• Iceberg lettuce (1 cup shredded), tomatoes (2 medium sliced): These keep everything fresh and crisp against the hot shrimp.
• Mayonnaise (1/2 cup): The creamy anchor that holds everything together and cools down the heat from frying.
• Hot sauce and dill pickle slices (optional): If you want extra tang and spice, these transform a good sandwich into an unforgettable one.
• Lemon wedges: A squeeze at the end brightens every bite.

Instructions

Get your shrimp ready:

Pat each shrimp completely dry with paper towels; any moisture will cause sputtering oil and uneven cooking. Take a moment to appreciate how plump they are before they hit the pan.

Build your coating mixture:

Whisk your eggs and buttermilk together in one bowl until they're pale and frothy, then combine your flour, cornmeal, and all those spices in another. The seasoning distribution matters more than you'd think; give it a few stirs to make sure the Cajun seasoning is evenly spread.

Coat each shrimp:

Dip each shrimp into the egg mixture, let the excess drip off for a second, then roll it in the flour-cornmeal blend until it's completely covered. This is oddly meditative work, and you'll start to notice the coating getting thicker as you go.

Heat your oil properly:

Pour about 2 inches of oil into your skillet and let it reach 350°F; if you don't have a thermometer, test with a tiny pinch of flour, and it should sizzle immediately. This temperature matters because too hot and your outside burns while the inside stays raw, too cool and you get greasy shrimp.

Fry in batches:

Lower your shrimp gently into the oil, working in batches so the temperature stays consistent; they'll sink at first, then float to the surface as they cook. Watch for that deep golden-brown color, which usually takes 2 to 3 minutes, then lift them out with a slotted spoon and let them drain on paper towels.

Prepare your bread:

Slice your rolls open lengthwise, but not all the way through; you want them hinged so they stay together. If the rolls are slightly warm, they'll accept the mayo better.

Mix and spread your mayo:

Stir your hot sauce into the mayo if you're using it, then spread it generously on both sides of each roll. The generous part matters; mayo is your moisture barrier here.

Build your sandwich:

Layer lettuce first so it protects the bread from getting soggy, then tomatoes, then your pile of hot, crispy shrimp. Tuck in a few pickles if you want that extra punch.

Serve without hesitation:

These need to be eaten right away while the shrimp is still hot and the lettuce is still crisp. Hand over lemon wedges so everyone can adjust the brightness to their taste.

Pin It

There's this moment right after you take that first bite of a freshly made po boy, when the textures are all happening at once and the flavors are singing together, and you understand why people in Louisiana aren't shy about their sandwiches. That's the moment this dish stops being lunch and becomes something you want to make again and again.

The Frying Truth

Deep-frying can feel intimidating, but it's honestly the most forgiving cooking method once you understand it. The oil does most of the work for you; you're mainly just managing temperature and timing. I used to fry things at whatever temperature seemed hot enough, and they always came out either raw or burnt, until I realized that an instant-read thermometer costs about five dollars and saves you from that frustration every single time.

Why Cornmeal Matters

The combination of flour and cornmeal is what separates a po boy from other fried shrimp sandwiches. Flour alone gives you a thin, delicate crust that doesn't last long, but cornmeal adds structure and actually stays crispy even after the shrimp has been sitting for a few minutes. The texture feels almost like eating a very delicate cornbread crust around each shrimp, which is exactly what you want.

Assembly and Serving Secrets

The order of assembly might seem random, but it's actually quite thoughtful. Lettuce first creates a barrier so the hot shrimp doesn't steam the bread into mush, and the tomatoes go on top of that so their juices have somewhere to drain. Some people add a thin spread of Creole mustard under the mayo, which adds a subtle heat that builds as you eat.

• If your shrimp are done but you're not ready to eat, keep them warm on a plate in a 200°F oven rather than letting them sit on paper towels.
• You can prep your lettuce and tomatoes an hour ahead, but assemble the sandwich only when the shrimp is hot and ready.
• Leftover fried shrimp gets soft by the next day, so eat them the same day you make them.

Making a po boy is one of those rare dishes where everything is simple, but the combination feels special. If you nail this recipe, you'll have a sandwich that tastes like you spent half the day on it, even though you only spent 35 minutes.
