If you love bold flavors and crispy textures, the Shrimp Po Boy with Creamy Cajun Sauce is a must-try sandwich that perfectly captures the spirit of Southern Louisiana cuisine. This iconic New Orleans sandwich is packed with crispy fried shrimp, fresh vegetables, and a rich, spicy sauce that brings everything together in one delicious bite.
What Is a Shrimp Po Boy?
The Po Boy sandwich is a traditional Louisiana favorite, originally created as an affordable meal for working-class people in New Orleans. “Po Boy” refers to the French term “poor boy,” highlighting its humble beginnings. Over time, it has become a beloved dish featuring various fillings like fried seafood, roast beef, or sausage, all served on crusty French bread.
The Shrimp Po Boy version is especially popular, known for its crunchy, golden fried shrimp piled high on a fresh baguette and topped with crisp lettuce, ripe tomatoes, and pickles.
Why Add Creamy Cajun Sauce?
While the classic Po Boy is delicious on its own with just mayonnaise or simple remoulade, adding a creamy Cajun sauce takes the sandwich to the next level. This sauce combines the creaminess of mayo with the bold, smoky, and spicy flavors of Cajun seasoning, garlic, and a hint of lemon. It complements the crispy shrimp perfectly and adds a burst of Southern flair.

Ingredients You’ll Need
To make an authentic Shrimp Po Boy with Creamy Cajun Sauce, gather the following ingredients:
- Shrimp: Medium-sized, peeled and deveined shrimp work best.
- Cajun seasoning: For dredging the shrimp and seasoning the sauce.
- Flour and cornmeal: Used to coat the shrimp for a crunchy crust.
- Buttermilk: To marinate the shrimp and help the coating stick.
- French bread or baguette: A crusty loaf is essential for the authentic Po Boy experience.
- Lettuce, tomato, and pickles: Fresh toppings for crunch and balance.
- Creamy Cajun sauce: Made with mayonnaise, Cajun spices, garlic, lemon juice, and a touch of hot sauce.
How to Make Shrimp Po Boy with Creamy Cajun Sauce: Step-by-Step
Step 1: Marinate the Shrimp
Start by marinating your shrimp in buttermilk mixed with a little Cajun seasoning. The buttermilk tenderizes the shrimp and adds flavor, while the Cajun seasoning begins to build that signature spicy taste.
Step 2: Prepare the Coating
Mix together flour, cornmeal, and more Cajun seasoning in a shallow bowl. This combination gives the shrimp a perfect crispy texture when fried.
Step 3: Coat and Fry the Shrimp
Remove shrimp from the marinade, dredge in the flour-cornmeal mixture, and fry them in hot oil until golden and crispy. Be careful not to overcrowd the pan for even cooking.
Step 4: Make the Creamy Cajun Sauce
Combine mayonnaise, Cajun seasoning, minced garlic, lemon juice, and a dash of hot sauce in a bowl. Mix well and adjust seasoning to your taste. This sauce will bring creamy, tangy heat that balances the fried shrimp beautifully.
Step 5: Assemble the Po Boy
Slice your French bread or baguette lengthwise, toast lightly if desired, and spread a generous amount of the creamy Cajun sauce on both sides. Layer on the crispy fried shrimp, fresh lettuce, sliced tomatoes, and pickles.
Step 6: Serve and Enjoy
Serve your Shrimp Po Boy immediately while the shrimp is hot and crunchy. Add extra sauce or hot sauce on the side for those who want more heat.
Tips for the Perfect Shrimp Po Boy
- Use fresh shrimp: Fresh or high-quality frozen shrimp will yield the best flavor and texture.
- Don’t skip the buttermilk: It’s key to tender shrimp and helps the coating stick.
- Maintain oil temperature: Fry at 350°F (175°C) for crispy shrimp without greasy texture.
- Use sturdy bread: A classic French baguette or hoagie roll will hold up to the juicy filling and sauces.
- Customize your sauce: Adjust the heat level by adding more or less hot sauce or Cajun seasoning.
