Air Fryer Teriyaki Tuna Steaks

Fresh Raw Tuna Steaks

Ingredients

Serves 2

  • 2 x 200g tuna steaks
  • 2 tbsp soy sauce
  • 1 tbsp mirin (What is mirin?)
  • 1 tbsp honey
  • 1 tbsp lime juice
  • 1 tsp ground ginger
  • 1 tsp sesame oil
  • 1 garlic clove minced
  • 1 tsp cornflour
  • Sesame seeds and finely chopped spring onion for garnishing

How To Cook Air Fryer Teriyaki Tuna

  1. Mix the soy sauce, mirin, honey, ginger, garlic, and sesame oil in a bowl. This is your teriyaki marinade. Add the tuna steaks to the bowl and let marinate for 20-30 minutes.
  2. Preheat your air fryer to 190C / 380F for 5 minutes.
  3. Place the marinated tuna steaks in the air fryer basket and reserve the marinade. Set the timer for 8 minutes. Turn the steaks halfway through.
  4. Meanwhile, pour the remaining marinade into a small pan. Combine the lime juice and cornflour to create a slurry and stir this into the marinade. Bring to a gentle simmer until the sauce thickens.
  5. Once the tuna steaks are cooked, let them rest for a minute or two, then slice them into thick strips.
  6. Drizzle over the teriyaki sauce and sprinkle with sesame seeds and chopped spring onions.

Air Fryer Tuna Cooking Times by Doneness

  • Pick your thickness: Measure your tuna steak and find its thickness in the chart.
  • Choose your doneness: Do you like it rare (pink), medium (a little pink), or well-done (no pink)?
  • Cook for the listed time: Look at the chart to see how long to cook based on your thickness and doneness.
  • Double-check with a thermometer: Don’t trust the timer completely! Stick a meat thermometer in the thickest part of your tuna to make sure it’s safe to eat (at least 63°C/145°F).
  • Tip: Medium-rare or medium is best for tuna, as it keeps it juicy.

Remember, air fryers can cook differently, so start with the shorter time and check with your thermometer for perfect tuna every time!

Can You Cook Frozen Tuna In The Air Fryer? 

Yes, you can but for this recipe, I would advise thawing the steaks completely before marinating.

If you don’t have time and you just want to cook a plain tuna fillet, it can be cooked from frozen.

How To Cook Frozen Tuna Steaks In Air Fryer

Season the tuna steaks well.

Preheat the air fryer to 180C/360F for 5 minutes.

Place the seasoned steaks into the air fryer basket and air fry for 10-15 minutes depending on your level of doneness. Refer to the chart above.

Check the internal temperature with a meat thermometer.

Remember to turn the steaks halfway through the cooking time.

Pro Tips

  • Thickness Counts: The cooking time is ideal for a steak that’s about 2 cm thick. Adjust accordingly if yours are thicker or thinner (see chart above).
  • Room Temperature: Let your steaks sit out for a bit before cooking. They cook more evenly that way.
  • Resting Time: Let your tuna steaks rest before cutting.
  • Don’t Overcrowd: Give each steak its own space in the air fryer to ensure proper air circulation.

What Do You Serve With Air Fryer Teriyaki Tuna Steaks?

Tuna Steaks With Air Fried Vegetables

Steamed Rice: Serve the tuna steaks with a side of steamed jasmine rice or brown rice to soak up the teriyaki sauce.

Avocado Salad: Prepare a simple avocado salad with ripe avocados, cherry tomatoes, cucumber, red onion, and a squeeze of lime juice for a creamy and refreshing side dish.

Sesame Cucumber Salad: Slice cucumbers thinly and toss them with a dressing made of rice vinegar, sesame oil, soy sauce, and sesame seeds.

Air Fried Asparagus: Air fry asparagus spears until tender and lightly charred, then drizzle them with a sesame soy glaze for a simple dish.

Storing, Refrigerating, and Freezing Your Air-Fried Teriyaki Tuna Steaks

Leftovers? No problem!

Here’s how to keep your air-fried teriyaki tuna steaks fresh and flavourful:

Refrigeration

  • Let your tuna steaks cool completely before storing them.
  • Transfer them to an airtight container or wrap them tightly in cling film.
  • Place them in the coldest part of your refrigerator (usually the back bottom shelf).
  • Well-stored tuna steaks will last for 2-3 days in the refrigerator.

Freezing

  • Freeze tuna steaks individually for the best results.
  • Wrap each steak tightly in cling film and then place it in a freezer-safe bag or container.
  • Label the bag with the date and contents.
  • Properly frozen tuna steaks can last for up to 3 months.

Thawing

  • When ready to enjoy again, thaw your tuna steaks in the refrigerator overnight.
  • You can also thaw them under cold running water for a faster option, but ensure the bag remains sealed to prevent water contamination.
  • Never thaw tuna at room temperature! This can promote bacterial growth and spoilage.

Reheating

  • You can reheat your thawed tuna steaks in the air fryer for a few minutes to regain their crispy texture.
  • Alternatively, reheat them gently in a pan over low heat or in the microwave, ensuring they reach an internal temperature of 145°F (63°C).

Additional Tips

  • If you anticipate freezing your tuna steaks, marinate them before cooking. Freezing won’t affect the marinade’s flavour, but it might impact the texture slightly.
  • If you find the thawed tuna steaks seem dry, consider serving them with a drizzle of the leftover teriyaki marinade or your favourite sauce.

Can I substitute tuna steaks with another fish? 

While tuna works best in this recipe, you can try using swordfish or halibut steaks with similar adjustments in cooking time.

What if I don’t have mirin? 

Substitute with sake mixed with 1 tbsp sugar, or dry sherry.

Can I omit the honey? 

Yes, the teriyaki glaze will still be flavourful without it.

How thick should the marinade coating be? 

Aim for a light, even coating on all sides of the tuna steaks.

Do I need to preheat the air fryer? 

Yes, preheating ensures the tuna cooks evenly and develops a crispy crust.

Can I crowd the air fryer basket? 

No, overcrowding will impede air circulation and prevent even cooking. Cook the tuna steaks in batches if necessary.

What if my air fryer doesn’t have temperature settings? 

Refer to the “cooking times for doneness” chart to estimate cooking time based on your desired level.

How do I know when the tuna is done? 

Use a food thermometer inserted into the thickest part of the steak. It should reach at least 63°C (145°F) for well-done, or your chosen doneness level.

Is it safe to eat tuna rare or medium-rare? 

Yes, as long as the internal temperature reaches 63°C (145°F). Medium-rare is often recommended for the best flavour and texture.

Will the teriyaki glaze burn in the air fryer? 

No, as the cooking time is relatively short. If concerned, reduce the glaze’s sugar content or baste the tuna instead of fully coating it.

How can I adjust the sweetness of the glaze? 

Add or reduce honey or brown sugar to your taste preference.

Can I add other spices or flavours to the marinade? 

Experiment with ginger, garlic, sesame seeds, or Sriracha for personalised variations.

How long will leftovers last? 

Properly stored in the refrigerator, they should last 2-3 days.

Can I freeze the leftover tuna steaks? 

Yes, freeze them individually for up to 3 months. Thaw properly before reheating.

Will reheating affect the texture? 

The tuna might lose some crispness when reheated. Use the air fryer again for a few minutes to revitalise the crust.
