If you're like me and looking for something delicious to impress your guests, this Ahi Tuna BBQ recipe fits the bill perfectly.

Ahi tuna is not your everyday fish. The rich, steak-like quality and its ability to take on various flavors make it a fantastic choice for grilling. With a slightly sweet and spicy marinade, this dish transforms simple ahi tuna steaks into a flavorful culinary experience that can easily become the highlight of any summer gathering.

The magic of this Ahi Tuna BBQ recipe lies in its stellar ingredient lineup. Ahi tuna steaks, at their best when fresh, form the core of the dish. For the marinade, I lean on a mix of low sodium soy sauce, toasted sesame oil, and honey for that sweet kick. A hint of cayenne adds a touch of heat, while a sprinkle of black pepper gives it depth. To amps up the savory notes, I also sneak in minced garlic, as it complements tuna beautifully.

- 2 ahi tuna (yellowfin tuna) steaks (about 4 oz. each, 1" thick)
- 1 tablespoon low sodium soy sauce
- 1 tablespoon toasted sesame oil
- 1 tablespoon honey
- 1 clove garlic, minced
- ½ teaspoon kosher salt (optional)
- ¼ teaspoon black pepper (adjust to taste)
- ¼ teaspoon cayenne pepper (optional)
- 1 tablespoon canola oil, or other high-heat oil
- Green onions, toasted sesame seeds, and lime wedges for garnish
Getting started with this Ahi Tuna BBQ recipe is a breeze. You’ll be in and out of the kitchen in no time, and you'll end up with a dish that feels fancy without all the fuss. Let’s walk through the steps together.

Begin by patting the ahi tuna steaks dry with a paper towel. This step is crucial; it ensures a good sear later. Once they’re dry, place them on a plate or inside a resealable plastic bag.

In a bowl, combine the low sodium soy sauce, toasted sesame oil, honey, minced garlic, kosher salt (if using), black pepper, and cayenne pepper. Whisk it together until the honey fully dissolves, and the mixture is well blended. When your marinade is ready, pour it over the tuna steaks, ensuring they are thoroughly coated. If you have a bit of time, let them marinate for at least 10 minutes; they can even hang out in the fridge overnight if you want to plan ahead!

Grab a medium skillet (I recommend using cast iron for that fantastic sear). Heat it on medium-high to high until it's smoking hot. If you’re using a nonstick pan, medium heat will suffice. Give your skillet about three to five minutes to reach the right temperature; not rushing this step will yield that irresistible crust!

Add the tablespoon of canola oil to the hot skillet. Carefully place the marinated tuna steaks in the skillet. Sear them for 1 to 1½ minutes on each side if you prefer that delightful medium-rare finish. For medium-well, aim for around 2 to 2½ minutes per side. Adjust your cooking times based on how thick the steak is and how hot your burner gets—every stove has its quirks!

Once cooked to your liking, transfer the tuna steaks to a cutting board. Let them rest for a minute and then slice them into half-inch strips. This is where it gets fun—garnish with green onions, sprinkle on some toasted sesame seeds, and serve with lime wedges for that zesty punch. If you saved a bit of marinade, feel free to drizzle it on top for additional flavor.
- Freshness Matters: Use the freshest ahi tuna you can find. The quality really shines through.
- Marination Time: If you have a solid hour, marinate the tuna steaks longer for more intense flavor.
- Watch the Heat: Adjust the cooking time based on the thickness of your steaks and how well-done you prefer them.
- Use Flaky Salt: If it needs more seasoning, sprinkle some flaky sea salt before serving for an added touch of flavor.
- Experiment: This recipe is versatile, so feel free to play with the marinade ingredients to fit your taste preferences!
If you have any leftovers (which I doubt, because it's that good!), store the cooked tuna in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat to avoid overcooking.
