Ingredients For Catfish Po Boy Recipe
Catfish: A mild-flavored fish that is perfect for frying.
Cornmeal: Adds a crunchy texture to the fried catfish.
All-purpose flour: Helps to create a crispy coating.
Cajun seasoning: A blend of spices that adds a flavorful kick.
Buttermilk: Used to tenderize the catfish and help the coating stick.
French rolls: Soft and airy bread that holds all the ingredients together.
Mayonnaise: Forms the base of the spicy mayo.
Hot sauce: Adds heat to the mayo.
Lettuce: Provides a fresh, crunchy layer.
Tomatoes: Adds juiciness and a touch of sweetness.

Technique Tip for Making a Po Boy
When frying the catfish, ensure the oil is at the right temperature, around 350°F. If the oil is too hot, the fillets will burn on the outside before cooking through. If it's too cool, the catfish will absorb too much oil and become greasy. Use a thermometer to maintain the correct temperature for perfectly crispy and golden catfish.

How To Store / Freeze Your Po Boy
Allow the catfish fillets to cool completely before storing. This prevents condensation, which can make the bread soggy.
Wrap each catfish fillet individually in aluminum foil or plastic wrap to maintain freshness.
Place the wrapped fillets in an airtight container or a resealable plastic bag. This helps to keep the fish from absorbing any unwanted odors from the fridge.
Store the french rolls separately in a bread box or a resealable plastic bag to keep them from becoming stale.
Keep the spicy mayo in a small airtight container in the refrigerator. It should last for up to a week.
For the lettuce, tomatoes, and pickles, store them in separate containers in the fridge to maintain their crispness and flavor.
To freeze the catfish fillets, place the individually wrapped fillets in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
Once frozen, transfer the fillets to a resealable freezer bag or an airtight container. Label with the date to keep track of freshness.
The catfish fillets can be frozen for up to 2 months. When ready to use, thaw them in the refrigerator overnight.
Avoid freezing the french rolls, lettuce, tomatoes, and pickles as they do not retain their texture well after thawing.
Reheat the catfish fillets in a preheated oven at 350°F (175°C) for about 10-15 minutes or until heated through. This helps to maintain their crispy texture.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover catfish fillets on a baking sheet lined with parchment paper. Cover them with aluminum foil to prevent drying out and bake for about 10-15 minutes until heated through.
For a quicker method, use a toaster oven. Set it to 350°F (175°C) and place the catfish fillets on the rack. Heat for about 8-10 minutes, checking frequently to ensure they don't overcook.
If you prefer using a microwave, place the catfish fillets on a microwave-safe plate. Cover with a damp paper towel to retain moisture and heat on medium power for 1-2 minutes. Check and continue heating in 30-second intervals until warmed through.
To reheat the french rolls, wrap them in aluminum foil and place them in a preheated oven at 350°F (175°C) for about 5-7 minutes until they are warm and slightly crispy.
For the spicy mayo, simply take it out of the fridge and let it come to room temperature. If you prefer it warmer, you can microwave it in a microwave-safe bowl for about 10-15 seconds, stirring halfway through.
To reheat the assembled Catfish Po Boy, wrap the entire sandwich in aluminum foil and place it in a preheated oven at 350°F (175°C) for about 10-15 minutes. This method helps maintain the texture of the bread and the catfish while warming the lettuce, tomatoes, and pickles slightly.
