Tuna Steak Preparation

  • 2 tuna steaks (about 6 oz each)
  • Salt and pepper to taste
  • Juice of 1 lemon

For the Marinade

To infuse your tuna steaks with flavor:

  • 1/4 cup soy sauce
  • 2 tablespoons olive oil
  • 1 tablespoon honey
  • 2 cloves garlic, minced
  • 1 teaspoon grated ginger

For the Coating

For that irresistible crunch:

  • 1 cup all-purpose flour
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 eggs, beaten
  • 1 cup panko breadcrumbs
  • About 2-3 cups of vegetable oil, enough to submerge the steaks in your frying pan

Tools and Equipment

To ensure your deep-fried tuna steak turns out perfectly, having the right tools and equipment is essential. Here’s what you’ll need to marinate, coat, and fry your tuna steaks to achieve that irresistible crunch and flavor.

For Marinating

  • Glass or Ceramic Bowl: Choose a non-reactive bowl such as glass or ceramic for marinating to avoid any unwanted chemical reactions that can alter the flavor of your tuna.
  • Whisk: Needed for thoroughly mixing the marinade ingredients to ensure that all flavors are well integrated.
  • Measuring Cups and Spoons: For accurately measuring your marinade ingredients, ensuring each steak is flavorful and delicious.

For Coating

  • Shallow Dishes: Use shallow dishes or plates for easy coating of the tuna steaks. You’ll need one for flour and another for breadcrumbs.
  • Sifter or Fine Mesh Strainer: To evenly and lightly dust your tuna steaks with flour to help the other coatings adhere better.
  • Tongs: These will help you handle the steaks without messing up the coating, keeping your hands clean and the crust intact.
  • Deep Fryer or Heavy-Bottomed Pot: A deep fryer is ideal for maintaining the correct oil temperature, but a heavy-bottomed pot can also work well.
  • Candy or Deep-Fry Thermometer: Crucial for monitoring the oil’s temperature, ensuring it’s hot enough to crisp the exterior while keeping the inside moist and tender.
  • Spider Strainer or Slotted Spoon: To safely remove the hot, crispy tuna steaks from the oil without breaking the crust.
  • Paper Towels: Prepare a plate lined with paper towels to drain excess oil off the fried tuna steaks, keeping them crispy and not soggy.
  • Timer: Keep track of frying time precisely to prevent overcooking, ensuring your tuna steaks are just perfect.


Now that you’ve gathered your tools and equipment, let’s move on to prepping your tuna steaks to achieve that delicious crispy exterior and succulent interior.

Marinating the Tuna

To begin, ensure your tuna steaks are clean and pat them dry with paper towels. This step is crucial for optimal marination.

  1. In a glass or ceramic bowl, combine 1/4 cup of olive oil, 2 tablespoons of soy sauce, the juice of one lemon, and a teaspoon of freshly ground black pepper. Whisk these ingredients together to form your marinade.
  2. Place your tuna steaks in the bowl, ensuring they are fully submerged in the marinade. Cover the bowl with plastic wrap and refrigerate. Allow the tuna to marinate for at least one hour, turning the steaks halfway through to ensure even flavor absorption.

Setting up the Frying Station

Before you begin frying, it’s important to set up your station efficiently to handle the process smoothly and safely.

  1. Fill your deep fryer or a heavy-bottomed pot with about two to three inches of vegetable oil. Heat the oil to 375°F (190°C). Use a thermometer to check the temperature, as accurate heat is critical for frying.
  2. While the oil is heating, set up a station next to your fryer with a large plate lined with paper towels for the cooked tuna steaks. This will help drain excess oil post-frying.
  3. Ensure your tongs and additional seasoning are within reach to manage the frying process effectively without any need to step away from the fryer.

With your tuna marinating and your frying station set up, you’re almost ready to cook a delightful deep-fried tuna steak.


Now that your tuna steaks are marinated and your frying station is set up, let’s dive into the cooking process.

Coating the Tuna Steaks

  1. Remove the marinated tuna steaks from the refrigerator.
  2. In a shallow dish, mix together 1 cup of all-purpose flour, 1 teaspoon of salt, and 1/2 teaspoon of ground black pepper.
  3. Coat each tuna steak evenly on all sides with the flour mixture. Tap off any excess flour to ensure a thin, even layer.

Deep Frying the Tuna Steaks

  1. Check the temperature of the oil in your fryer or deep pan to ensure it’s at 375°F (190°C).
  2. Carefully place each coated tuna steak into the hot oil using tongs. Avoid overcrowding the pan to maintain the oil temperature.
  3. Fry the tuna steaks for about 3-4 minutes on each side or until golden brown and crispy.
  4. Use tongs to carefully remove the tuna steaks from the oil and drain them on the prepared paper towels. Sprinkle lightly with salt while they’re still hot.

Resting and Serving the Crispy Deep-Fried Tuna Steaks

  1. Let the fried tuna steaks rest for a couple of minutes after frying. This step allows the juices to redistribute, ensuring the steak remains moist and flavorful.
  2. Serve your crispy deep-fried tuna steaks on a warm plate with a side of fresh lemon wedges and your choice of dipping sauce.
  3. Garnish with chopped herbs if desired for an extra touch of freshness.
