An authentic catfish po boy sandwich topped with shredded lettuce, tomato, and mayonnaise on a toasted French bread loaf. This recipe features our Southern fried catfish and popular fish fry seasoning.
Clean and trim catfish fillets. Then, combine mustard and hot sauce in a large bowl. Toss catfish in mustard mixture, coating them evenly on all sides. Set aside.
Make fish fry seasoning. Mix together the cornmeal, Old Bay, lemon pepper seasoning, kosher salt, black pepper, and granulated garlic in a shallow bowl. Set aside.
Heat vegetable oil to 350°F in a large fry pan or deep fryer. While the oil heats up, dredge mustard-coated catfish fillets in the cornmeal seasoning mixture, making sure each fillet is fully covered.
Once oil reaches the correct temperature, fry catfish in batches until golden brown and the internal temperature reaches 145°F. Use a slotted spoon or spatula to carefully remove fried catfish and transfer them to a wire rack over a paper towel.
Next, slice the French bread loaf into 2 pieces and split each piece lengthwise. Spread butter on the cut side of each piece. Then, in a hot skillet, place the bread butter-side down and toast until golden and crispy.
Assemble the po' boys. Spread mayonnaise on both sides of the toasted bread. Add shredded lettuce, tomato slices, and a fried catfish fillet to each sandwich.
Notes
Toast the bread in butter adds flavor but also creates a nice crunch. Don’t skip this step!
Add your favorite toppings like sliced pickles or a spicy slaw for added crunch and flavor.
Try different sauces like a remoulade or tartar sauce if you want to switch things up.
