Easy Blackened Swordfish

Background and History:

Blackened swordfish is a popular seafood dish known for its bold and spicy flavor. The blackening technique, a cooking method developed in the American South, involves coating the fish in a blend of herbs and spices and searing it in a hot, cast-iron skillet to create a delicious, dark crust. This method imparts a smoky flavor and a spicy kick to the swordfish, making it a favorite among seafood enthusiasts.


  • 4 swordfish steaks (6-8 ounces each)
  • 2 tablespoons paprika
  • 1 tablespoon dried thyme
  • 1 tablespoon dried oregano
  • 1 tablespoon garlic powder
  • 1 tablespoon onion powder
  • 1 tablespoon cayenne pepper (adjust to taste)
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 4 tablespoons unsalted butter
  • 2 tablespoons olive oil
  • Lemon wedges for garnish


  • In a small bowl, combine paprika, dried thyme, dried oregano, garlic powder, onion powder, cayenne pepper, salt, and black pepper. This mixture forms the blackening seasoning.
  • Rub the blackening seasoning generously on both sides of the swordfish steaks. Be sure to coat them evenly, and press the seasoning into the flesh.
  • In a large cast-iron skillet, heat olive oil and butter over high heat until the butter foams and sizzles.
  • Carefully place the seasoned swordfish steaks in the skillet. Cook for about 3-4 minutes on each side, or until the fish flakes easily with a fork and has a blackened, slightly crispy crust.
  • Serve hot with lemon wedges for a refreshing contrast to the spicy flavors.
