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 also camping. 

What You'll Need

  • 1 1/2 cups/360 mL unsalted butter, melted
  • 6 firm fish fillets (about 1/2" to 3/4" thick)
  • 3 tablespoons/45 mL cajun blackening spices

How to Make It

1. Preheat grill with heavy cast-iron skillet or griddle in the grill. Get it good and hot. This might take anywhere from 15-30 minutes.  Reserve 12 tablespoons of melted butter for serving and pour the rest into a shallow dish.

2. Dip each fillet into butter and sprinkle Cajun blackening spices on both sides. Place into the skillet. Cook about 2-3 minutes or until the bottom is almost black but not burned.

Carefully flip over, so fillets do not break. Pour about a teaspoon of butter on the cooked side and continue cooking about 2-3 minutes or until fillet is finished (internal temperature of 150 degrees F). Remove fish from pan and place onto a large platter or individual plates.

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