Equipment

  • 12-inch oven-safe skillet

Ingredients
  

  • 2 swordfish steaks or select cuts
  • 2 tablespoons olive oil
  • ¼ teaspoon paprika
  • ¼ teaspoon kosher salt
  • ¼ teaspoon onion powder
  • ¼ teaspoon garlic powder
  • ⅛ teaspoon black pepper
  • ⅛ teaspoon cayenne pepper
  • ⅛ teaspoon oregano
  • 2 tablespoons unsalted butter softened
  • ½ lemon, zested
  • 1 teaspoon lemon juice

Instructions
 

  • Preheat oven to 350 degrees Fahrenheit.
  • Heat a 12-inch nonstick or cast iron skillet over medium-high heat.
  • While the pan heats up, make the spice mixture. In a small bowl, combine the paprika, salt, pepper, cayenne, oregano, onion powder, and garlic powder. Mix with a spoon.
  • Dry the swordfish steaks with a paper towel, then sprinkle ¼ teaspoon of the spice mixture on top of each steak, coating the entire surface.
  • Add the olive oil to the hot skillet. Carefully place the steaks into the skillet, seasoned side down.
  • Let the steaks sear for 5 minutes. Do not move them.
  • Use a thin-set spatula to carefully turn the steaks over. Immediately place the skillet into the oven and bake for 8 to 10 minutes. When it's opaque and flakes easily, it's done!
  • While the swordfish cooks, make the Cajun butter. In a small bowl, mash the butter with the remaining spice mixture, lemon zest, and juice.
  • Use an oven mitt to carefully remove the hot pan from the oven. Do not touch the handle with your bare hands!
  • Use a thin set spatula to transfer the swordfish steaks to serving plates. Top each steak with two teaspoons of Cajun butter. Enjoy!
