How to Make Shrimp Po’Boy Croissants
Step 1: Make the Remoulade
Combine all of the remoulade ingredients in a bowl and stir until smooth and fully incorporated. Refrigerate while you prepare the remaining ingredients to allow the flavors to develop.
Step 2: Marinate the Shrimp
In a separate bowl, combine the shrimp with the buttermilk, garlic, mustard, onion powder, salt, and black pepper. Toss until every shrimp is coated and allow them to marinate for about 10 to 15 minutes.
Step 3: Prepare the Breading
Whisk together the flour, cornmeal, onion powder, garlic powder, paprika, salt, and black pepper until evenly combined.
Step 4: Fry the Shrimp
Heat canola oil to 330°F.
Working in batches, remove the shrimp from the marinade and coat each piece thoroughly in the seasoned flour mixture. Shake off any excess before carefully lowering them into the hot oil.
Fry for 3 to 4 minutes, or until the shrimp are golden brown, crispy, and fully cooked. Transfer them to a cooling rack to keep the coating crisp.
Step 5: Toast the Croissants
Slice each croissant in half and lightly toast until warm and slightly crisp around the edges.
Step 6: Assemble the Sandwiches
Spread a generous layer of remoulade sauce onto the bottom half of each toasted croissant.
Pile on the crispy shrimp, followed by seasoned tomato slices and fresh lettuce.
Finish with another drizzle of remoulade, sprinkle with chopped chives, and place the toasted croissant top on each sandwich.
Serve immediately while the shrimp are hot and crispy.
Tips for the Best Shrimp Po’Boy
- Pat the shrimp dry before marinating if they contain excess moisture.
- Don’t overcrowd the fryer. Cook in batches so the oil temperature stays consistent.
- Toasting the croissants keeps them from becoming soggy.
- Let the fried shrimp rest on a cooling rack instead of paper towels to maintain maximum crispiness.
- Make the remoulade a few hours ahead of time for even better flavor.
Variations
- Add sliced pickles for extra crunch and acidity.
- Use brioche buns if croissants aren’t available.
- Add pepper jack cheese for an extra layer of richness.
- Toss the fried shrimp in Cajun seasoning for even more spice.
- Top with shredded cabbage instead of lettuce for additional crunch.

Storage & Reheating
Store leftover fried shrimp separately from the vegetables and croissants in an airtight container in the refrigerator for up to 2 days.
Reheat the shrimp in an air fryer or oven until hot and crispy. Avoid microwaving, as it softens the breading.
Store the remoulade separately and assemble the sandwiches just before serving for the freshest results.
Frequently Asked Questions
