Tuna steaks are a great option for a quick and easy weeknight meal, and cooking them in an air fryer yields tender, flaky tuna with a deliciously crisp exterior. The air fryer method is faster, simpler, and healthier than traditional cooking methods like oven baking or pan-searing. It also reduces the mess and splatter that can come with pan-searing. When it comes to cooking tuna steaks in an air fryer, the most important factors to consider are the temperature and duration of cooking, as well as the quality and preparation of the tuna steaks.

Marinating tuna steaks
To cook fresh tuna in an air fryer, it is recommended that you preheat the air fryer to 380–400°F and then cook the tuna steaks for 3–4 minutes. You can also cook frozen tuna steaks in the air fryer; defrost them first or cook them from frozen. If cooking from frozen, preheat the air fryer to 380°F and cook the frozen tuna for 4 minutes before adding the marinade.
Now, onto the fun part—marinating your tuna steaks! Marinating tuna steaks is a great way to infuse them with flavor and create a delicious meal. Here's a step-by-step guide to help you achieve the perfect marinade:
Step 1: Choose Your Marinade Ingredients
The first step to marinating tuna steaks is to select your marinade ingredients. You can choose from a wide variety of ingredients to create a blend that suits your taste preferences. Here are some popular options:
- Soy sauce
- Olive oil
- Lemon or lime juice
- Rice vinegar
- Toasted sesame oil
- Garlic
- Brown sugar
- Basil
- Oregano
- Cilantro
- Jalapeno
Step 2: Prepare the Marinade
Once you've gathered your chosen ingredients, it's time to prepare the marinade. Combine the ingredients in a small bowl or a shallow dish and whisk them together until they are well blended. You can adjust the quantities of each ingredient to suit your taste. Don't be afraid to experiment and find the perfect blend for your palate!
Step 3: Marinate the Tuna Steaks
Place the raw tuna steaks in a shallow glass dish, a large plastic storage bag, or a gallon-sized zip-lock bag. Pour the prepared marinade over the tuna steaks, ensuring that they are fully coated. You can also add the tuna steaks directly to the bowl or dish with the marinade and turn them to coat. Cover the dish with plastic wrap or seal the bag, removing as much air as possible.
Step 4: Refrigerate and Marinate
Place the covered dish or sealed bag of tuna steaks in the refrigerator. The marinating time can vary depending on your preference and the specific recipe you are following. Some recipes suggest marinating for as little as 10 minutes, while others recommend 30 minutes to an hour. For a more intense flavor, you can even marinate the tuna steaks overnight or for up to 8–24 hours, turning them occasionally to ensure even coating. Remember, it is important not to marinate the tuna for too long, as it can start to break down the texture of the fish.
Step 5: Remove from the Marinade and Cook
Once the tuna steaks have finished marinating, remove them from the marinade, shaking off any excess. At this point, you can cook the tuna steaks in your preheated air fryer, following the cooking instructions mentioned earlier. Alternatively, you can sear the steaks in a hot pan or grill them, especially if you want to achieve a nice crust or caramelization from the sugars in the marinade.
Tips and Tricks:
- When purchasing fresh tuna steaks, look for ones that are firm, deep red, and don't have a strong fishy smell.
- Pat the tuna steaks dry with a paper towel before placing them in the marinade. This will help the tuna absorb the flavors more effectively.
- Always preheat your air fryer before cooking the tuna steaks to achieve that perfect sear on the outside without overcooking the inside.
- Use a meat thermometer to check the doneness of your tuna steaks. For medium-rare steaks, aim for an internal temperature of 125°F.
- Tuna steaks are best enjoyed fresh, so it is not recommended to freeze leftovers as it may affect their texture and flavor.

Preheating the air fryer
Preheating your air fryer is a crucial step in achieving that perfect sear on your tuna steak without overcooking the inside. While some recipes suggest preheating the air fryer to 400°F (200°C), others recommend 380°F, depending on the desired doneness of your tuna steak.
For a well-done tuna steak, preheat your air fryer to 400°F (200°C) for around 5 minutes. This higher temperature will help to create a beautiful sear on the outside of your tuna steak. It is important to note that cooking time may vary depending on the thickness of your steak, so adjust accordingly.
If you prefer your tuna steak medium-rare, preheat your air fryer to 380°F. This slightly lower temperature will ensure that the inside of your tuna steak remains nice and pink, while still achieving a delicious sear on the exterior. Again, adjust the cooking time based on the thickness of your tuna steak.
When cooking frozen tuna steaks, preheat your air fryer to 380°F and cook the frozen tuna for 4 minutes. Then, add the marinade and let it sit for at least 10 minutes before placing the steaks back into the preheated air fryer for another 3-4 minutes. This will result in a delicious, evenly cooked tuna steak.
By preheating your air fryer and adjusting the temperature and cooking time based on your desired doneness, you can ensure that your tuna steak turns out perfectly every time.

Cooking times and temperatures
The cooking time for fresh tuna in an air fryer depends on the level of doneness you want to achieve. It is recommended to preheat the air fryer for about 3 to 5 minutes before adding the tuna.
For a medium-rare steak, cook the tuna for 4 to 5 minutes at 370 °F. You can also cook it at 360 °F for 2 minutes on each side, which will give you a total cooking time of 4 minutes. If you prefer your tuna on the rarer side, 4 minutes at 380 °F should be sufficient.
If you want a medium steak, cook the tuna for 5 to 6 minutes at 370 °F. For a medium steak, you can also cook it at 360 °F for a total of 4 minutes (2 minutes on each side).
For a well-done steak, cook the tuna for 6 to 7 minutes at 370 °F.
It is important to note that the FDA recommends cooking all raw fish to an internal temperature of 145 °F to prevent foodborne illness. However, tuna cooked to this temperature may become dry and tasteless. To achieve a perfect medium-rare finish, cook the tuna to an internal temperature of 125 °F.

Resting and serving the tuna
After cooking the tuna steaks in the air fryer, remove them from the air fryer basket and let them rest for a couple of minutes. This helps to retain the juices and ensures the tuna is juicy and tender. The steaks will continue to cook for a short time during the resting process due to residual heat.
While the tuna steaks are resting, you can prepare any final garnishes or sides. For a simple and elegant presentation, slice the tuna steaks against the grain and arrange them on a serving platter or individual plates. You can drizzle the steaks with lemon juice or a sauce of your choice, such as a soy sauce or salsa fresca. For added texture and flavour, sprinkle the steaks with sliced green onions, chives, sesame seeds, or a combination of these ingredients.
If you prefer your tuna well-done, you can also give it a quick sear on a hot skillet after air frying. This will add a crispy exterior to the tuna steaks without overcooking the interior. Just be mindful not to overcook the tuna, as it can dry out and become less appealing in texture and taste.
Tuna steaks pair well with a variety of sides. For a refreshing option, serve the tuna on a bed of mixed greens or alongside a fresh salad with a citrus vinaigrette. If you're looking for something heartier, roasted or grilled vegetables like asparagus, zucchini, or bell peppers make a great accompaniment. Complement the dish with quinoa or roasted potatoes for a more satisfying meal. Alternatively, serve the tuna steaks with a side of rice, either steamed jasmine rice or mushroom rice, for an Asian-inspired twist.

Make sure to pat the tuna steaks dry before placing them in the marinade so they can really soak up all the flavor. Don't marinate the tuna for too long, or it can start to break down the texture and become overly salty.
