Ingredients for One-Pan Blackened Catfish with Cajun Green Beans

Instructions

In a small bowl, combine smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, black pepper, and salt to create the blackening spice mix.
Pat the catfish fillets dry with paper towels. Rub both sides of each fillet evenly with 1 tablespoon olive oil.
Coat each fillet generously with the blackening spice mix, pressing it onto the fish to ensure it adheres well.
Heat a large heavy skillet or cast-iron pan over medium-high heat. Once hot, add the remaining 1 tablespoon olive oil and heat until shimmering.
Add the catfish fillets to the pan and sear without moving for about 3-4 minutes, until a dark crust forms and the edges begin to look opaque.
Carefully flip the fillets and cook for another 3-4 minutes until the fish flakes easily with a fork. Remove the fillets from the pan and set aside on a warm plate.
In the same pan, add the trimmed green beans. Toss them in the pan juices and add smoked paprika, Cajun seasoning, garlic powder, and a pinch of salt.
Sauté the green beans for about 5-7 minutes, stirring frequently until they are tender-crisp and slightly blistered.
Squeeze the juice of half a lemon over the green beans and give them a final toss to combine.
Return the catfish fillets to the pan just to warm through for about 1 minute with the green beans.
Garnish with fresh chopped parsley if desired and serve immediately.
