Marinating tuna steaks

Tuna is a mild-flavoured fish, making it perfect for absorbing the flavours of a marinade. Marinating tuna steaks can be done in a few simple steps.

Firstly, prepare the marinade. A simple blend of soy sauce, rice vinegar, toasted sesame oil, garlic, and a sprinkling of brown sugar is a popular choice. You can also add a dash of lime juice, olive oil, cilantro, jalapeno, and garlic for a kick of heat. Alternatively, for a citrusy, savoury marinade, blend orange juice, soy sauce, olive oil, fresh parsley, oregano, garlic, and lemon juice.

Next, place the tuna steaks in a large plastic bag and pour in the marinade, ensuring the fish is fully coated. Seal the bag, removing as much air as possible, and place it in a baking dish to contain any mess. Leave the tuna to marinate in the refrigerator for 15 minutes to two hours. However, be careful not to leave the tuna in the marinade for too long, as the acids can ruin the texture of the fish. Aim for a marination time of 20 to 30 minutes for the best results.

Finally, remove the tuna steaks from the marinade, shaking off any excess. Heat a skillet or grill to medium-high heat and lightly grease it. Add the steaks and cook each side for one to three minutes, depending on the desired level of doneness. For a rare tuna steak, cook each side for just a couple of minutes to get a good sear.

Your marinated tuna steaks are now ready to be served! Enjoy them with a light side dish like a simple salad or roasted asparagus.

Preheating the air fryer

Preheating your air fryer is a crucial step in the cooking process. It ensures that your tuna steak gets a nice sear on the outside without overcooking the inside. This step should never be skipped!

The first step in preheating your air fryer is to set the temperature. Most recipes recommend preheating your air fryer to between 380°F and 400°F. However, it's important to note that the ideal temperature may vary slightly depending on your air fryer model and your desired level of doneness for the tuna steak. For example, if you prefer your tuna steak well-done, you may need to preheat your air fryer to a slightly higher temperature.

Once you have set the temperature, you can turn on your air fryer and let it preheat for 5 minutes. During this time, you can prepare your tuna steak by patting it dry with a paper towel, rubbing it with oil, and seasoning it with salt and pepper or any other desired spices and herbs. This step ensures that your tuna steak will have a flavour-packed crust.

If you are cooking frozen tuna steaks, you may need to adjust the preheating process slightly. One option is to preheat your air fryer to 380°F and then place the frozen tuna steaks in the air fryer for 4 minutes before adding the marinade. This will help to ensure that your tuna steaks are cooked through without drying out.

Cooking times and temperatures

The cooking time and temperature for air fryer tuna steaks vary depending on the desired level of doneness. For a rare tuna steak, cook the tuna for 2 minutes on each side, resulting in a total cooking time of 4 minutes. The internal temperature should be around 115°F (46°C). If you prefer your tuna steak to be medium-rare, increase the cooking time to 7-8 minutes, with an internal temperature of 125°F (52°C). For a well-done tuna steak, cook for 8-10 minutes.

It's worth noting that the default setting for most air fryer tuna steak recipes is 400°F (200°C) for around 10 minutes, which yields a tuna steak that is seared on the outside and medium-rare in the centre. However, every air fryer model is unique, with varying wattages and heating elements, so the cooking time and temperature may differ slightly. It's important to get to know your air fryer and adjust the settings accordingly.

When cooking tuna steaks in an air fryer, it is crucial to preheat the air fryer before adding the tuna. This helps to create a sear on the outside without overcooking the inside. Additionally, it is recommended to pat the tuna steaks dry and season them with salt and pepper on both sides before placing them in the air fryer.

For those who enjoy their tuna steak with a crunchy crust, consider coating it in sesame seeds before air frying. This sesame-crusted tuna steak can be cooked in under 10 minutes, with 2 minutes on each side for a rare steak, and additional time for a more well-done preference.

When reheating tuna steaks, it is best to use a lower temperature to avoid overcooking. Set your air fryer to 380°F and heat the tuna for 2-3 minutes. Alternatively, you can quickly reheat it in a pan or cast-iron skillet on medium-high heat for 1 minute per side.

Resting and serving

If you have cooked your tuna steaks in advance, you can store them in an airtight container in the refrigerator for up to 3 days. It is best to consume the tuna within 2-3 days to ensure the best quality and freshness. If you are serving the tuna steaks cold, you can cook them the day before and then let them cool to room temperature before storing them in the refrigerator.

When you are ready to serve, slice the tuna steaks against the grain into uniform slices. You can serve the tuna steaks with a drizzle of lemon juice, a sprinkle of sesame seeds and sliced green onions. For a sweet and tangy taste, you can also drizzle balsamic glaze over the steaks before serving.

For a light and refreshing meal, serve the tuna steaks on a bed of mixed greens or alongside a fresh salad. You can also serve the tuna steaks with sushi rice and nori as part of a sushi bowl, or in a poke bowl with sesame mayo or sriracha mayo.

Reheating and storing

Leftover tuna steaks can be stored in an airtight container in the refrigerator for up to 3 days. However, it is recommended to consume them within 2-3 days for optimal quality and freshness.

If you want to reheat your tuna steaks, it is best to do so in an air fryer set to 380ºF for 3-5 minutes. Preheating the air fryer beforehand is essential to ensure even heating. Alternatively, you can reheat the tuna steaks in a pan or cast-iron skillet on medium-high heat for 1 minute per side.

When reheating, it is crucial not to overcook the tuna steaks, as this can lead to dryness and negatively impact the taste. For rare tuna steaks, a shorter reheating time of around 2 minutes is recommended.

If you prefer to eat your leftover tuna steaks cold, they can be a great addition to salads, spring rolls, or pasta dishes, providing a healthy and nutritious boost to your meal.
