This is the traditional way to blacken fish in a heavy cast-iron skillet. The advantage of doing it outdoors on the grill is that you won't fill the kitchen with smoke. This recipe is great for outdoor entertaining and camping.


  • 1 1/2 cups unsalted butter (melted)
  • 6 firm fish fillets (about 1/2- to 3/4-inch thick)
  • 3 tablespoons cajun blackening spices

Steps to Make It

  1. Gather the ingredients.

  2. Preheat grill with heavy cast-iron skillet or griddle in the grill. Get it good and hot, 15 to 30 minutes.

  3. Reserve 12 tablespoons of melted butter for serving and pour the rest into a shallow dish.

  4. Dip each fillet into butter and sprinkle Cajun blackening spices on both sides.

  5. Place into the skillet and cook for 2 to 3 minutes or until the bottom is almost black but not burned.

  6. Carefully flip so fillets do not break.

  7. Pour about a teaspoon of ​butter on the cooked side and continue cooking about 2 to 3 minutes or until fillet is finished (internal temperature of 150 F).

  8. Remove fish from pan and place onto a large platter or individual plates.

  9. Serve immediately with 2 tablespoons of butter for dipping.

  10. Enjoy!

Kitchen Note

  • It's best to cook about 2 fillets at a time. Wipe the skillet clean between each batch of fillets and keep the temperature nice and hot.
