Marinating tuna steaks
Tuna steaks are a great option for a quick and easy meal, and cooking them in an air fryer is a fast, efficient, and healthy way to prepare this dish. Before you cook your tuna steaks in the air fryer, you'll want to marinate them to add flavour and moisture.
Firstly, it's important to note that tuna steaks are best served from rare to medium-rare. You can cook them more well-done, but this can dry out the fish. Tuna steaks are best enjoyed rare as they are mild-flavoured and can easily take on other flavours. Marinating tuna steaks is a great way to add flavour to the fish, and it only takes 15 minutes to 2 hours, with 30 minutes being ideal. You don't want to marinate for too long, or the acids in the marinade will start to break down the texture of the fish.
To prepare your tuna steaks for marinating, pat them dry with a paper towel. This will help the steaks absorb the flavours of the marinade. Then, place the steaks in a large plastic bag or bowl and pour in your chosen marinade, ensuring the fish is fully coated. Seal the bag, removing as much air as possible, or cover the bowl. Place the tuna steaks in the fridge and chill for 15 minutes to 2 hours, with 30 minutes being ideal. Flip the steaks halfway through for an even coating.
There are many different marinade recipes to try, but a simple and popular option is an Asian-inspired blend of soy sauce, rice vinegar, toasted sesame oil, garlic, and a sprinkling of brown sugar. You can also add a dash of lime juice or honey for a touch of sweetness and some fresh herbs like cilantro and parsley. Another option is to combine olive oil, lemon juice, soy sauce, basil, oregano, and garlic powder, seasoning with salt and pepper to taste.
Once your tuna steaks have finished marinating, remove them from the marinade and shake off any excess. Then, they are ready to be cooked in the air fryer for 4-10 minutes, depending on your desired level of doneness and the model of your air fryer.

Preheating the air fryer
Preheating your air fryer is a crucial step in cooking tuna steaks. It ensures that you get a nice sear on the outside of the tuna without overcooking the inside. Depending on your air fryer model, you should preheat it to at least 370°F-400°F (200°C) for around 5 minutes. If you have a Gourmia air fryer, preheat it to 380°F.
It is important to note that every air fryer model is unique, with varying wattages and heating elements, which means that there can be slight differences in the cooking time and temperature for each one. Therefore, it is recommended to get to know your air fryer and adjust the cooking time and temperature accordingly.
When preheating your air fryer, make sure the basket is empty and that the lid is closed. This will ensure that the air fryer can reach the desired temperature evenly. Once the air fryer has preheated, you can proceed with cooking your tuna steaks.
It is also important to ensure that your tuna steaks are at room temperature before placing them in the air fryer. This will help ensure even cooking. If your tuna steaks have been in the refrigerator, let them sit on the counter for about 15-20 minutes before cooking.

Cooking times and temperatures
The cooking time for tuna steaks in an air fryer depends on the level of doneness you want to achieve. For a medium-rare steak, cook the tuna for around 4 to 5 minutes. For a medium steak, increase the cooking time to 5 to 6 minutes, and for a well-done steak, cook for 6 to 8 minutes. These timings are for steaks of similar size; if your steaks vary in size, you may need to adjust the cooking time to prevent overcooking.
The temperature settings for an air fryer will also depend on your desired level of doneness and the model of the air fryer. Most recipes recommend preheating the air fryer to around 380°F to 400°F (about 200°C). However, it is important to note that each air fryer model is unique, with varying wattages and heating elements, so the cooking time and temperature may need slight adjustments.
To achieve a rare to medium-rare tuna steak, you may need to reduce the cooking time to 7 to 8 minutes. The internal temperature for a rare steak should be around 115°F (46°C), while a medium-rare steak should have an internal temperature of 125°F (52°C).
If you prefer your tuna steaks well-done, you can increase the cooking time to 10 minutes or cook for 5 to 6 minutes on each side. It is important to keep an eye on the steaks and adjust the cooking time as needed, as tuna steaks can quickly become dry and rubbery if overcooked.
For frozen tuna steaks, it is recommended to thaw them overnight in the fridge or use a quick thaw method in a cold water bath before cooking. Frozen tuna steaks may cook unevenly and have an overcooked exterior if not properly defrosted.

Resting and slicing the tuna steaks
Once your tuna steaks are cooked, remove them from the air fryer and let them rest. The resting period for tuna steaks is usually shorter than for other meats. This is because tuna steaks are typically served seared on the outside and raw on the inside, and resting can cause them to "cook" for too long.
To rest your tuna steaks, place them on a rack set over a tray to encourage excess heat to dissipate. This will help the tuna steaks cool down to almost room temperature. The cooler the tuna steaks become, the easier they will be to slice.
After resting, place the tuna steaks on a board with criss-crossing grill lines facing up. Then, use a sharp knife to slice the tuna steaks into uniform slices, holding the edges with your fingers to prevent the seared surface from crumbling.
Finally, transfer the tuna steaks to a serving plate and separate the slices slightly so that the insides are just visible, or arrange them at a slight angle so that they overlap each other.
