Ingredients For Catfish Po Boy Recipe
Catfish: Fresh or frozen, thawed fillets are the star of this dish, providing a mild, flaky fish base.
Cornmeal: Used to create a crispy coating for the catfish fillets.
Flour: Combined with cornmeal to form the breading mixture.
Cajun seasoning: Adds a spicy, flavorful kick to the breading.
Buttermilk: Helps the breading adhere to the fish and adds a slight tang.
French bread: Split rolls that hold the sandwich together, providing a soft, chewy texture.
Lettuce: Shredded and used as a fresh, crunchy topping.
Tomato: Sliced and added for juiciness and flavor.
Mayonnaise: Spread on the rolls to add creaminess and moisture.
Hot sauce: Drizzled on top for an extra layer of heat and flavor.
Technique Tip for This Recipe
When preparing the catfish fillets, ensure they are patted dry with a paper towel before dipping them in buttermilk. This helps the cornmeal mixture adhere better, resulting in a crispier coating. Additionally, let the coated fillets rest for a few minutes before frying to allow the breading to set, which helps prevent it from falling off during cooking.

How To Store or Freeze This Dish
- Allow the catfish fillets to cool completely before storing. This prevents condensation, which can make the coating soggy.
- Wrap each catfish fillet individually in plastic wrap or aluminum foil to maintain their crispiness and prevent them from sticking together.
- Place the wrapped fillets in an airtight container or a resealable plastic bag. If using a bag, squeeze out as much air as possible before sealing.
- Store the catfish fillets in the refrigerator if you plan to eat them within 2-3 days. For longer storage, place them in the freezer.
- To freeze the catfish fillets, lay them flat in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to a resealable plastic bag or airtight container.
- For the french bread rolls, store them in a bread box or a resealable plastic bag at room temperature for up to 2 days. To freeze, wrap each roll in plastic wrap and place them in a resealable plastic bag or airtight container.
- Shredded lettuce and sliced tomato should be stored separately in airtight containers in the refrigerator. Use within 1-2 days for optimal freshness.
- Mayonnaise and hot sauce can be stored in their original containers in the refrigerator. Ensure the lids are tightly sealed to maintain freshness.
- When ready to reheat, preheat your oven to 350°F (175°C). Place the catfish fillets on a baking sheet and heat for 10-15 minutes, or until warmed through and crispy.
- Assemble the Catfish Po Boy as directed in the recipe, using the reheated catfish fillets, fresh lettuce, tomato, and french bread rolls.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the catfish fillets on a baking sheet lined with parchment paper. Cover them loosely with aluminum foil to prevent drying out. Heat for about 10-15 minutes, or until the fillets are warmed through.
For a quicker method, use a microwave. Place the catfish fillets on a microwave-safe plate and cover them with a damp paper towel. Heat on medium power for 1-2 minutes, checking frequently to avoid overcooking.
To reheat the French bread rolls, wrap them in aluminum foil and place them in a preheated oven at 350°F (175°C) for about 5-7 minutes, or until they are warm and slightly crispy.
If you prefer a stovetop method, heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter. Place the catfish fillets in the skillet and heat for about 2-3 minutes per side, or until warmed through.
For the lettuce and tomato, it’s best to use fresh ingredients. However, if you must reheat, place them in a microwave-safe dish and heat on low power for 20-30 seconds, just enough to take the chill off without making them soggy.
Reassemble your Catfish Po Boy by spreading fresh mayonnaise on the warmed French bread rolls. Add the reheated catfish fillets, fresh or lightly warmed lettuce and tomato, and drizzle with hot sauce. Serve immediately and enjoy!
