🧂Blackening Seasoning

There are many blackening seasoning options that you can use for this recipe. If you plan on trying my carne asada seasoning recipe, you'll need the ingredients below:

🐟 How To Make Blackened Swordfish

Step 1: Make sure the swordfish is completely defrosted. Pat dry with paper towels to remove excess moisture. Sprinkle seasoning in one layer onto a plate. Brush the fish fillet with olive oil on both sides and dip into seasoning.

Pro Tip: Another option is to sprinkle the fish with the seasoning, and don't forget the sides!

Step 2: Heat a cast iron skillet until very hot. Melt ½ tablespoon of unsalted butter into the pan than add the seasoned swordfish. Cover with a lid and cook over medium-high heat for 2 minutes.

Pro Tip: Covering the pan as the swordfish is being seared not only cooks the fish faster, it also keeps the smoke down and keeps you from breathing the cloud of spices, which can trigger coughing and choking.

Step 3: Flip the swordfish to the other side, cover, and cook for an additional 2 minutes, or until the fish is cooked through (145 degrees F) and flakes easily.

🍽 Serving Suggestions

Enjoy blackened swordfish with morel mushroom and prawn risotto, a pear salad, or edamame dill rice.

Another option is to make fish burritos or to to add the fish to a salad similar to this smoked salmon salad. Finally, you can make a blackened swordfish sandwich.

🥖Blackened Swordfish Sandwich Directions

Step 1: To make a blackened swordfish sandwich, prepare lemon garlic aioli and my honey and vinegar coleslaw. If you prefer spicy food, mix a 1 ½ tablespoons of chimichurri sauce with 1 cups of shredded cabbage and use instead of coleslaw.

Step 2: Next, butter ciabatta bread. Place the bread, buttered side down and grill in a hot pan until golden brown. Place the bread on a plate and cover with foil to keep warm while you prepare the swordfish as described above.

Pro Tip: Another option is to slather mayo on the bread instead of butter, then grill as usual.

Step 3: To plate your fish dinner, spread lemon aioli on both sides of your grilled bread then add the fish steak, coleslaw, and red onion. You can also add other toppings like cheese, tomato slices, pickles, lettuce, etc.
