Instructions

Step 1: Preheat grill to medium-high heat (about 400°F). Pat dry 4 catfish fillets (6 oz each) and brush both sides with 2 tbsp olive oil. Season evenly with 1 tbsp Cajun seasoning, 1 tsp salt, and 1/2 tsp black pepper.
Step 2: Place the catfish fillets on the grill and cook for 4-5 minutes per side, or until the fish flakes easily with a fork and has grill marks.
Step 3: While the fish grills, melt 4 tbsp unsalted butter in a small saucepan over medium heat. Add 2 minced garlic cloves and sauté for 1 minute until fragrant.
Step 4: Stir in 2 tbsp fresh lemon juice and 1 tsp fresh orange zest, cooking for another 30 seconds until the sauce is warm and aromatic.
Step 5: Remove the catfish from the grill and spoon the citrus butter sauce evenly over each fillet. Garnish with 1 tbsp chopped fresh parsley before serving.
