Ingredients
- 1 lb large shrimp, peeled and deveined
- 2 tbsp Cajun seasoning
- 1/2 cup all-purpose flour
- 1/2 cup buttermilk
- 2 cups vegetable oil
- 4 hoagie rolls
- 8 leaves romaine lettuce leaves
- 1/2 cup mayonnaise
- 1 tbsp Dijon mustard
- 1 tbsp lemon juice
- 1 tsp hot sauce
- 1 tsp paprika
- 1/2 tsp garlic powder
- 1/2 tsp salt
- 1/4 tsp black pepper
Instructions
- Step 1: In a medium bowl, combine 2 tbsp Cajun seasoning with 1/2 cup all-purpose flour. In another bowl, pour 1/2 cup buttermilk. Dip each of the 1 lb peeled and deveined large shrimp first into the buttermilk, then dredge in the seasoned flour to coat completely.
- Step 2: Heat 2 cups vegetable oil in a deep skillet over medium-high heat until it reaches 350°F on a thermometer. Fry the coated shrimp in batches for 2-3 minutes until golden brown and crispy, then drain on paper towels.
- Step 3: To prepare the remoulade sauce, whisk together 1/2 cup mayonnaise, 1 tbsp Dijon mustard, 1 tbsp lemon juice, 1 tsp hot sauce, 1 tsp paprika, 1/2 tsp garlic powder, 1/2 tsp salt, and 1/4 tsp black pepper in a small bowl until smooth.
- Step 4: Slice 4 hoagie rolls lengthwise and toast lightly. Spread a generous 2 tbsp of remoulade sauce inside each roll, then layer 2 lettuce leaves and a portion of the fried shrimp evenly.
- Step 5: Serve immediately while the shrimp are warm and crispy for a flavorful Southern sandwich experience.
