There’s nothing quite like biting into a sandwich that’s overflowing with smoky, spicy, and juicy shrimp, tucked inside a crusty roll with creamy sauce and crisp veggies. That’s the magic of Spicy Shrimp Rolls, also known as a Cajun Grilled Shrimp Po Boy. Every bite is a mix of bold Cajun heat, buttery shrimp sweetness, and the refreshing crunch of lettuce and tomatoes, all brought together with a luscious spicy mayo. It’s comfort food that feels indulgent yet fresh, making it the kind of sandwich you’ll crave again and again.

Behind the Recipe

This sandwich was inspired by the Po Boy, a New Orleans classic that dates back to the 1920s. Traditionally stuffed with fried seafood or roast beef, it was served on crisp French bread and became a working man’s staple. I wanted to capture that soul but give it a lighter, grill-inspired twist. Instead of frying, we marinate plump shrimp in Cajun spices and grill them to smoky perfection. The result is a sandwich that’s just as bold and satisfying, but with a fresher feel.

Recipe Origin or Trivia

The Po Boy has deep roots in Louisiana cuisine, created by Bennie and Clovis Martin, who offered free sandwiches to striking streetcar workers. The “poor boys” became “Po Boys,” and the sandwich grew into a New Orleans legend. While fried oysters and roast beef remain traditional fillings, modern variations celebrate everything from catfish to shrimp. This Cajun Grilled Shrimp version leans into Louisiana’s love for seafood and spice, paying tribute to the classic while embracing a healthier, fiery edge.
