- Olive Oil: Used in the marinade. It can be replaced with another neutral oil like canola or vegetable oil.

🍽 Equipment
A good reliable smoker is key for this smoked tuna steaks recipe. A Traeger Pellet Grill or a Pit Boss pellet grill are two of my favorites. However, you can use other grills, such as an electric smoker or Weber grill.
A reliable meat thermometer, like the ThermaPen ONE by ThermoWorks, is a must-have tool to ensure your tuna is cooked to perfection.
You will also need Ziploc bags for marinating, a baking sheet for carrying the tuna steaks to and from the grill, and tongs.
🔥How To Make This Smoked Tuna Recipe
First, prepare the marinade by whisking together the olive oil, soy sauce, lemon juice, mustard, honey, garlic powder, black pepper, and sea salt in a small bowl.


Now for the next step, rinse the tuna fillets under cold water and pat them dry with paper towels. Place the tuna in a shallow dish, large bowl, or Ziploc bag.
Pour the marinade over the tuna, making sure they are evenly coated. Seal the bag and refrigerate for 20-30 minutes. You don't want to do it for longer than 30 minutes as the marinade contains lemon juice, which will start to cook the tuna.


While the tuna is marinating, preheat your pellet grill to 225 degrees F. Fill your hopper with the wood pellets of your choice. Some good options are mesquite, alder, oak, Big Game blend, and Signature blend.
Once the grill is preheated, place tuna steaks directly on the grill grates. Make sure to leave enough space between each steak for proper airflow.

Insert a meat thermometer into the thickest part of your fillet. This will ensure your tuna is cooked exactly how you like it.
Close the lid and let the fish steaks cook undisturbed for about 30 minutes. Flip the tuna steaks over to get those grill lines, and check the internal temperature of the fish.
Top Tip: The USDA recommends a final internal temperature of 140-145 degrees F. However, if you prefer your tuna medium-rare, you will want an internal temperature of 125-130 degrees F. Please see the chart below for the desired level of doneness.
Continue to cook the tuna until it reaches the desired internal temperature, then remove the fish from the grill. Let it rest for a few minutes to allow the juices to redistribute.
Top Tip: The smoking time will depend on the thickness of your fish, how hot your grill cooks, and other factors like outside temperature, etc. The fish will take anywhere from 30 minutes to 60 minutes to cook, depending on how you like it done.

Serve the smoked tuna as a main dish alongside your favorite side dishes. It goes great topped with a sprinkle of fresh parsley alongside a glass of white wine.
I like to serve it on a bed of rice, topped with sesame seeds. You can also flake the smoked tuna and use it in sandwiches, tacos, salads, or in smoked tuna dip. The possibilities are endless!
Enjoy!
