This marinated tuna steak air fryer recipe has plenty of flavor from a simple mix of olive oil, lemon juice, garlic, salt, and black pepper. I like that the tuna gets a full 30 minutes in the marinade before cooking, so the seasoning isn’t just sitting on the outside when you serve it.
The air fryer also keeps the cooking part quick, with the tuna needing just 8–10 minutes at 400ºF. If you want another easy fish recipe, try this Air Fryer Salmon Fillet Recipe.

Try This Marinated Tuna Steak Air Fryer
If tuna steak sometimes seems a little plain on its own, this is one of those air fryer recipes where marinade makes a big difference without covering up the fish. The lemon adds simplicity and freshness, while the garlic, salt, and black pepper give the tuna a simple savory flavor.
I especially like the contrast between the cooked outside and the juicy center, and you don't even need soy sauce, Worcestershire, tamari sauce, or any weird substitutions to get the best texture. It’s also one of those delicious recipes where you don’t need a complicated sauce or lots of ingredients to make the tuna taste good. Get the full instructions and quantities in the recipe card below.
Why You’ll Love This Air Fryer Tuna Steak Recipe
- Simple marinade: Olive oil, lemon juice, garlic, salt, and pepper are all you need.
- Juicy inside: Keeping an eye on the cooking time helps prevent the tuna from becoming overcooked.
- Quick cooking: The tuna only needs 8–10 minutes in the air fryer.
- Plenty of flavor: The 30-minute marinating time gives the seasoning time to get into the tuna before cooking.
Ingredients
- Tuna steaks: I make sure the raw tuna steaks are properly dried before adding the marinade. This helps the oil and seasonings cling to the surface instead of getting watered down by excess moisture. You can use ahi tuna (yellowfin and bigeye) for this recipe.
- Olive oil: This forms the base of the marinade and makes it easy to coat both sides of the tuna evenly for the perfect sear. Sesame oil is another option if you want to give the marinade more of an Asian-style seafood flavor.
- Lemon juice: I like the little bit of brightness this adds against the richer tuna and olive oil. Lime juice or orange juice can also be used when you want to change the citrus flavor.
- Garlic powder: Garlic powder mixes straight into the marinade and gives the tuna garlic flavor without needing to chop anything. I like that it keeps this marinade especially quick to put together.
How to Make Marinated Tuna Steak Air Fryer Style
1. Rinse and pat dry tuna steaks with a paper towel.
2. In a marinating dish or small bowl, mix olive oil, garlic powder, lemon juice, salt, and black pepper to create your marinade.
3. Coat both sides of the tuna steaks with the marinade and allow them to marinate at room temperature for 30 minutes.
4. Preheat your air fryer to 400ºF (200ºC). Place the marinated tuna steaks in the air fryer basket.
5. Air fry tuna for 8-10 minutes. Be careful not to overcook the tuna; it should remain juicy inside. You can flip the tuna steaks halfway through cooking.
6. Once done, carefully remove the tuna from the air fryer and garnish with some sesame seeds and fresh parsley. Serve it hot with your favorite dipping sauce and veggies. Enjoy your meal!
Recipe Tips
- Dry the tuna steaks thoroughly before marinating them so the marinade clings properly.
- Don’t skip the 30-minute marinating time.
- Use a meat thermometer to check the tuna. An internal temperature of 130ºF–140ºF is recommended.
- Lightly brush the air fryer basket with oil before cooking to help prevent sticking.
- Keep an eye on the tuna because thicker steaks and different air fryers can change the cooking time.
- When I am in the mood for some variations, I like adding some red pepper flakes for a bit of a bite. You can also add a tiny bit of honey for a sweeter combo, which is one of my favorite tricks.
- You can store leftovers in the refrigerator in an airtight container for up to 3 days, but I doubt there will be any!

FAQs
Marinating tuna steaks for more than an hour can be overkill. The acidic components in the marinade, like lemon juice, can start to "cook" the fish if left too long, leading to a mushy texture when cooked.
Absolutely! Seasoning is super important. I always season my tuna steaks before they hit the air fryer; it helps to lock in those flavors and gives you that delicious crust we all love.
The secret is not to overcook them. I keep a close eye on my tuna steaks, cooking them just until they reach an internal temperature of 130ºF to 140ºF, ensuring they stay moist and tender inside.
Tuna steaks are best cooked at a high temperature for a short time. In an air fryer, I cook them at 400ºF, which sears the outside quickly while keeping the inside juicy.
