Air Fryer Spicy Cajun Grilled Swordfish Steaks
Firm swordfish steaks get a bold Cajun crust in the air fryer for a quick seafood dinner with lemon and parsley.

Ingredients
- 2 swordfish steaks (6-8 ounces each, about 1-inch thick)
- 1 tablespoon olive oil
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon dried oregano
- 1 teaspoon dried thyme
- 1/2 teaspoon cayenne pepper (adjust to taste)
- 1/2 teaspoon black pepper
- 3/4 teaspoon kosher salt
- 1/2 teaspoon dried white pepper (optional)
- 1/4 teaspoon cayenne pepper flakes (optional, for extra heat)
- 1 lemon, cut into wedges (for serving)
- Fresh parsley, chopped (for garnish)
Instructions
-
Pat the swordfish steaks dry with paper towels to remove excess moisture.
-
In a small bowl, combine smoked paprika, garlic powder, onion powder, dried oregano, dried thyme, cayenne pepper, black pepper, kosher salt, and white pepper (if using). Mix well to create the Cajun spice blend.
-
Brush both sides of each swordfish steak with olive oil to help the seasoning stick and enhance crisping.
-
Generously rub the Cajun spice blend evenly over both sides of each steak, pressing lightly to adhere the spices.
-
Preheat your air fryer to 400 F (200 C) for 3-5 minutes.
-
Place the seasoned swordfish steaks in the air fryer basket in a single layer, making sure they don't overlap for even cooking.
-
Air fry at 400 F for 8-10 minutes, flipping halfway through at 4-5 minutes. The swordfish should develop a light golden crust and reach an internal temperature of 145 F (63 C).
-
Carefully remove the steaks from the air fryer and let them rest for 3 minutes to allow the juices to redistribute.
-
Serve your spicy Cajun grilled swordfish steaks with fresh lemon wedges and garnish with chopped parsley for a pop of color and freshness.
-
Enjoy immediately with your favorite sides like sautéed greens or cauliflower rice.
Storage
Refrigerate cooked swordfish in an airtight container for up to 2 days. Keep lemon wedges and fresh garnishes separate so the fish does not become watery.
Freezing cooked swordfish is not ideal because the lean fish can turn dry and firm after thawing. If needed, wrap tightly and freeze for up to 1 month, then thaw overnight in the refrigerator.
Reheat gently in the air fryer at 350 F for 3 to 4 minutes, just until warmed through. Avoid long reheating because swordfish overcooks quickly.
FAQ
How do I keep swordfish from drying out?
Cook just to 145 F and rest for 3 minutes. Pull the steaks as soon as they flake but still look moist in the center.
Can I make this less spicy?
Yes. Cut the cayenne in half and skip the pepper flakes, then add extra smoked paprika for Cajun-style color.
Do I need to flip swordfish in the air fryer?
Yes. Flipping halfway helps both sides form a light crust and keeps the thick steak cooking evenly.
