I suggest when you try this blackened catfish recipe, that you do it outside on the grill. There is a lot of smoke and strong vapors from the pepper and to be on the safe side you need to be in a well ventilated area.


Spice Mix:
  • 3/4 tsp cayenne pepper
  • 1 tsp lemon pepper*
  • 1 tsp garlic powder
  • dash kosher salt
  • dash ground pepper


Preheat the grill on medium-high heat and place a large heavy skillet on the grill. Add 2 tablespoons of canola oil and heat until it's really hot.

Preheat oven to 350 degrees and grease a medium baking dish. Set aside.

Meanwhile, mix the cayenne pepper, lemon pepper, garlic powder, kosher salt and ground pepper together. Brush/spray the fillets lightly with canola oil and sprinkle with the spice mix.

Sear both sides of the fish in the cast iron pan on the grill for 2 minutes per side until lightly blackened. We are NOT cooking the fish at this point.

Bring back into the house and place the fillets in the prepared baking dish. Pour the Italian salad dressing over the fillets and brush with the mustard. Bake for 30 minutes or until the fish flakes easily with a fork.

*If you do not have lemon pepper, just squeeze lemon over the fillets before you brush them with mustard. Mustard gives it a zing that's good with the heat.
