What Is a Po’ Boy Sandwich?
A po’ boy is a classic Louisiana sandwich traditionally served on soft French bread and stuffed with fried seafood or roast meat. Originating in New Orleans, po’ boys are known for their simple ingredients, generous portions, and bold flavors. Fried catfish is one of the most popular versions, especially outside the city, where catfish is plentiful and affordable. Finished with lettuce, tomato, pickles, and a creamy remoulade, the po’ boy is comfort food at its finest.

Step-by-Step Instructions
Step 1. Make the Remoulade
Whisk all the Po Boy Sauce ingredients in a mixing bowl, cover, and refrigerate until ready to serve.
Step 2. Make the Breading
In a shallow dish, stir together the cornmeal, flour, Cayenne pepper, black pepper, kosher salt, and Cajun seasoning.
In a separate mixing bowl, whisk the egg and milk together. Set both bowls aside.
Now slice the bread rolls to your desired size and set those aside.
Step 3. Bread the Fish
Cut the catfish filets in half to make them easier to fit in the sandwich, then pat them dry with a paper towel.
Place the sliced fish filets in the milk, then coat them with the cornmeal breading mixture. Let the fish rest until ready to fry.
Preheat your oil in a deep fryer to 365°f.
Step 4. Fry the fish and assemble the Sandwich
Once the oil has reached temperature, add 3 to 4 catfish filet strips to the fryer and cook for about 3 ½ to 4 minutes. The fish should be golden brown and flaky.
Remove the fried catfish to a paper-towel-lined cookie sheet, dress your sandwiches with a layer of pickles, sliced tomatoes, fried catfish, shredded lettuce, Cajun remoulade, and top it off with hot sauce.
Expert Tips
Use catfish fillets that are evenly sized. Even thickness helps the fish cook evenly and prevents over-browning before the inside is done.
Season the fish and the breading. Flavor should be layered. Season the catfish itself, then season the cornmeal or flour mixture so every bite tastes bold.
Let the breaded catfish rest before frying. Allowing the coated fish to rest for 5–10 minutes helps the breading stick and creates a crunchier crust.
Fry at the right temperature. Keep the oil between 365–375°F. Too hot and the coating burns; too cool and the fish absorbs oil.
Make the remoulade ahead of time. Like most sauces, it tastes better after sitting. Let it chill for at least 30 minutes so the flavors meld.
Recipe FAQs
Traditional po’ boys use New Orleans–style French bread that’s soft on the inside with a light crust. If unavailable, use hoagie rolls, soft French rolls, or a soft Italian loaf.
Yes, just thaw it completely and pat it very dry before seasoning and breading.
Remoulade is the classic choice. It’s creamy, tangy, and slightly spicy, perfect for fried seafood.
Yes. Air fry at 400°F for 10–12 minutes, flipping halfway. Baking works too, but frying gives the best texture.
French fries, coleslaw, potato salad, or even Swamp Soup are perfect pairings.
