Method
Mix the Cajun seasoning
Combine 5 g of smoked paprika, 1 g of dried thyme, 1 g of dried oregano, 3 g of garlic powder, 2 g of onion powder, 1 g of ground cayenne pepper, 2 g of ground black pepper, and 6 g of kosher salt in a small bowl. Reserve one-quarter of the mixture for the maque choux and keep the rest for the catfish.
Prepare the vegetables and catfish
Dice 150 g of red bell pepper, 150 g of yellow onion, 100 g of celery stalks, and 180 g of ripe tomato. Mince 3 garlic cloves, slice 4 green onions, and cut 1 lemon into wedges; reserve half the wedges for squeezing into the maque choux and half for serving. Pat 680 g of catfish fillets dry with paper towels on a separate board. Wash the knife, board, and your hands after handling the raw fish, and keep the fish away from the prepared vegetables.
Soften the maque choux vegetables
Melt 28 g of unsalted butter for maque choux in a wide skillet over medium heat. Add the prepared onion, red bell pepper, and celery. Cook, stirring often, until the onion looks translucent and the pepper and celery begin to soften, 5 to 7 minutes; start checking at 5 minutes.
05:00Add the corn and aromatics
Add 500 g of sweet corn kernels, the prepared tomato, garlic, and reserved seasoning to the skillet. Cook over medium heat, stirring and scraping the skillet, until the garlic smells fragrant and the tomato begins to release its juice, about 2 minutes.
02:00Simmer the maque choux
Pour in 120 ml of heavy cream and bring the mixture to a gentle simmer. Reduce the heat to medium-low and cook uncovered, stirring every few minutes, until the corn is tender and the cream lightly coats the kernels instead of pooling in the pan, 10 to 12 minutes; start checking at 10 minutes. Remove from the heat, squeeze in the reserved lemon wedges for the maque choux, and stir in most of the green onions.
10:00Season the catfish
Melt 14 g of unsalted butter for catfish and stir in 15 ml of canola oil. Brush the mixture over both sides of 680 g of catfish fillets, then press the remaining Cajun seasoning evenly onto the fillets. Use clean utensils for the seasoned fish and discard any butter mixture that touched raw fish.
Sear the first side
Heat a large cast-iron or heavy skillet over medium-high heat until a drop of water sizzles and evaporates quickly, but the skillet is not smoking heavily. Add the fillets without crowding, working in batches when needed. Cook without moving them until the underside develops a dark mahogany crust and releases readily from the skillet, 3 to 4 minutes; start checking at 3 minutes.
03:00Finish cooking the catfish
Turn the fillets with a clean spatula and cook the second side until the flesh is opaque, separates into moist flakes at the thickest point, and reaches 63°C/145°F on a food thermometer, 2 to 4 minutes; start checking at 2 minutes. Transfer the cooked fish to a clean plate. Lower the heat if the spices smell scorched before the center reaches temperature.
02:00Plate and serve
Taste the maque choux and adjust the seasoning only if needed. Spoon it onto warm plates, set the blackened catfish alongside, and finish with the remaining green onions and lemon wedges. Serve immediately while the spice crust is crisp and the corn is creamy.
Smart Substitutions
- No catfish? Use tilapia, snapper, or another firm fish fillet of similar thickness, and cook it to 63°C/145°F.
- No fresh corn? Use frozen sweet corn kernels; add them directly and allow an extra minute or two for excess moisture to evaporate.
- No heavy cream? Use half-and-half or evaporated milk for a lighter sauce that still binds the corn and vegetables.
- Prefer gentler heat? Reduce the cayenne by half and keep the paprika, thyme, oregano, garlic, and black pepper for a full-flavored crust.
Tips and Variations
- Dry the catfish thoroughly before seasoning; surface moisture softens the crust and encourages sticking.
- Run the exhaust fan and open a nearby window before the fish hits the skillet, since toasted spices can create a burst of smoke.
- Stop simmering the maque choux while it still looks slightly loose; it thickens as it is spooned onto the plates.
What Went Wrong?
- Spices burn before the fish is cooked Lower the heat to medium, move the skillet briefly off the burner, and continue cooking until the center reaches 63°C/145°F.
- Catfish sticks to the skillet Let the crust set before turning. A fillet that resists usually needs another 30 to 60 seconds before it will release cleanly.
- Maque choux is watery Simmer it uncovered over medium-low heat, stirring often, until the cream and vegetable juices lightly coat the corn.
- Corn is still firm Cover for 2 minutes so the corn steams in the existing cream and vegetable juices, then uncover and continue cooking until the kernels are tender and the mixture is lightly coated.
