What Type of Fish to Use

Swordfish is a large fish that is found in tropical waters around the world. It is known for its long, bill (sword) it uses to stun and kill its prey. They are considered a delicacy and are more expensive and can be difficult to find in standard grocery stores. It is considered a good source of protein and omega-3 fatty acids.

You can substitute any of your favorite white fish in the recipe if desired.

How Does it Taste

Swordfish steaks have a mild, slightly sweet flavor with a firm and meaty texture. The flavor is often described as similar to tuna, but with a more meaty taste. It is rich in oil which gives it a delicious buttery flavor.

Smoker Temperature

You will want to smoke the fish at 225 degrees.

Cook Time/How Long to Cook

It will typically take 60-90 minutes to smoke the fish. Cook the fish until it reaches an internal temperature of 145 degrees. Some like to cook their seafood to around 135 degrees. Do what you prefer.

How to Tell When it’s Finished Cooking

  • The flesh should be opaque and should not have any translucent or raw-looking areas.
  • The fish should flake easily when poked with a fork.
  • The internal temperature of the fish should reach 135- 145 degrees.

When using a meat thermometer always check the thickest part of the fish. If you overcook the fish it will be dry and lack flavor. Hence, why it may work best to cook it to an internal temperature of 135 degrees because the fish will continue to cook for a few minutes as it rests away from heat.

What Flavor of Wood/Pellets to Use

Mesquite, oak, or the Traeger signature blend will work great for this recipe

How to Store Leftovers

Leftovers can be stored in the fridge tightly covered and sealed for 3-4 days.

How to Reheat

  • Oven or Air Fryer: Place the swordfish in an oven-safe dish and cover it with foil at 350 degrees. Heat until warm.
  • Stovetop: Heat a small amount of oil or butter in a skillet over medium heat. Place the swordfish in the skillet and cook for 2-3 minutes per side or until warm.
  • Microwave: I don’t recommend it at all for fish. If you must use it, be quick, because the microwave will dry out the fish.
