From the Test Kitchen

Native to the Americas, the sweet potato has been cultivated in Louisiana for centuries. Its hearty sweetness does wonders for all kinds of dishes. Here, we’re roasting sweet potatoes with Cajun spices and serving them with a New Orleans classic: the po’ boy sandwich. In keeping with tradition, we’re filling soft rolls with lightly fried seafood—we’re using cornmeal-coated catfish—and remoulade (a zesty, creamy sauce), for a meal that celebrates both regional and seasonal cuisine.

tips & techniques
Prepare the ingredients:
1 Prepare the ingredients:

Preheat the oven to 450°F. Wash and dry the fresh produce. Slice the sweet potatoes into ½-inch-thick rounds. Cut off and discard the root end of the lettuce; thinly slice the leaves. Thinly slice the parsley leaves and stems. Slice the rolls lengthwise, keeping them intact (they should look like hot dog buns).

Roast the sweet potatoes:
2 Roast the sweet potatoes:

Place the sweet potatoes on a sheet pan. Drizzle with olive oil and season with salt, pepper and half the spice blend; toss to thoroughly coat. Arrange in a single, even layer. Roast 22 to 24 minutes, or until browned and tender when pierced with a fork. Transfer to a serving dish and set aside in a warm place.

Make the remoulade:
3 Make the remoulade:

While the sweet potatoes roast, in a medium bowl, combine the mayonnaise, sweet pickle relish, mustard and ¾ of the parsley; stir to combine and season with salt and pepper to taste.

Coat the catfish:
4 Coat the catfish:

While the sweet potatoes continue to roast, combine the cornmeal and remaining spice blend on a plate. Pat the catfish fillets dry with paper towels; season with salt and pepper on both sides. Thoroughly coat the seasoned fillets in the cornmeal-spice blend mixture (pressing to adhere). Place the coated fillets on a plate.

Cook the catfish:
5 Cook the catfish:

While the sweet potatoes continue to roast, in a large pan (nonstick, if you have one), heat a thin layer of oil on medium-high until hot. Add the coated catfish fillets. Cook 3 to 5 minutes per side, or until golden brown and cooked through. Remove from heat.

Toast the rolls & serve your dish:
6 Toast the rolls & serve your dish:

While the catfish cooks, place the rolls on a sheet pan, cut sides up. Toast in the oven 2 to 3 minutes, or until the edges are lightly browned. Transfer to a clean, dry work surface. Divide half the lettuce between the toasted rolls. Top with the cooked catfish fillets, a few spoonfuls of the remoulade (reserving the rest) and some of the remaining lettuce (you may have extra lettuce). Transfer to a serving dish. Serve with the roasted sweet potatoes and remaining remoulade on the side. Garnish with the remaining parsley. Enjoy!
