Heat a skillet over medium high heat. Add the butter and oil and cook until the butter has melted and the mixture is hot.
While butter is melting, add the paprika, garlic powder, onion powder, cayenne, salt, pepper, basil, oregano, and thyme to a small dish and stir to combine. Sprinkle the filets liberally with the seasoning.
Add the fish to the skillet and cook for 3-4 minutes on each side, until fish is cooked through and nicely browned.
Squeeze lemon over the fish and sprinkle with parsley before serving.
Notes
If you prefer to use store bought blackened seasoning you’ll want about 2 tablespoons total to coat the fish.
