Seared Ahi Tuna this Recipe

Ingredients:

  • Ahi Tuna Steaks: 2 (6-8 ounce) steaks, about 1 inch thick, sushi-grade
  • Sesame Seeds: 2 tablespoons, a mix of black and white for visual appeal
  • Olive Oil: 2 tablespoons, extra virgin
  • Soy Sauce: 3 tablespoons, low sodium
  • Rice Vinegar: 2 tablespoons
  • Sesame Oil: 1 teaspoon, toasted sesame oil for intense flavor
  • Fresh Ginger: 1 tablespoon, grated
  • Garlic: 2 cloves, minced
  • Honey: 1 tablespoon (or maple syrup for a vegan option)
  • Red Pepper Flakes: 1/4 teaspoon (or more, to taste, for heat)
  • Green Onions: 2, thinly sliced, for garnish
  • Wasabi Paste: Optional, for serving
  • Pickled Ginger: Optional, for serving
  • Sea Salt: To taste
  • Black Pepper: Freshly ground, to taste

Preparing the Tuna:

Okay, let’s get started! The key to amazing seared ahi tuna is using high-quality, sushi-grade tuna. Don’t skimp on this! It makes all the difference. Also, make sure your tuna is very cold before you start. This helps it sear properly without overcooking the inside.

  1. Pat the Tuna Dry: Use paper towels to thoroughly pat the tuna steaks dry. This is crucial for getting a good sear. Excess moisture will steam the tuna instead of searing it.
  2. Season Generously: Season both sides of the tuna steaks with sea salt and freshly ground black pepper. Don’t be shy! The seasoning will create a flavorful crust.
  3. Prepare the Sesame Seed Coating: On a small plate, combine the black and white sesame seeds. Mix them well. This creates a beautiful and flavorful coating for the tuna.
  4. Coat the Tuna: Gently press each side of the tuna steak into the sesame seed mixture, ensuring an even coating. The sesame seeds should adhere well to the slightly damp surface of the tuna. Press firmly but gently to ensure they stick.

Making the Marinade/Sauce:

While the tuna is resting (and getting even colder!), let’s whip up a quick and flavorful marinade that will double as a delicious sauce. This marinade is a perfect balance of salty, sweet, and tangy, with a hint of heat.

  1. Combine the Ingredients: In a small bowl, whisk together the soy sauce, rice vinegar, sesame oil, grated ginger, minced garlic, honey (or maple syrup), and red pepper flakes.
  2. Taste and Adjust: Give the marinade a taste and adjust the seasonings to your liking. If you prefer a sweeter sauce, add a little more honey. For more heat, add more red pepper flakes. If it’s too salty, add a splash more rice vinegar.
  3. Set Aside: Set the marinade aside. We’ll use some of it to drizzle over the tuna after searing.

Searing the Tuna:

Now for the most important part: searing the tuna! This is where you need to pay close attention. The goal is to create a beautiful, crispy crust on the outside while keeping the inside rare and tender. A screaming hot pan is essential!

  1. Heat the Pan: Place a heavy-bottomed skillet (cast iron is ideal) over high heat. Add the olive oil and let it heat up until it’s shimmering and almost smoking. This is crucial for achieving a good sear.
  2. Sear the Tuna: Carefully place the sesame-crusted tuna steaks into the hot pan. Sear for about 1-2 minutes per side for rare, or slightly longer for medium-rare. The exact time will depend on the thickness of your tuna steaks and the heat of your pan. Do not overcrowd the pan! If your pan is small, sear the tuna steaks one at a time.
  3. Watch for the Sear: You’ll know the tuna is ready to flip when a golden-brown crust has formed and the tuna releases easily from the pan. Don’t force it! If it sticks, it’s not ready yet.
  4. Don’t Overcook: The key to perfect seared ahi tuna is to avoid overcooking it. The center should still be mostly raw. Remember, you can always cook it a little longer, but you can’t uncook it!
  5. Remove from Pan: Once seared to your liking, immediately remove the tuna steaks from the pan and place them on a cutting board.

Slicing and Serving:

Almost there! Now it’s time to slice the tuna and plate it beautifully. Presentation is key!

  1. Let it Rest (Briefly): Let the tuna steaks rest for a minute or two before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
  2. Slice Against the Grain: Using a sharp knife, slice the tuna steaks against the grain into 1/4-inch thick slices. This makes the tuna easier to chew and enhances its tenderness.
  3. Arrange on Plates: Arrange the sliced tuna on plates. You can fan them out for a visually appealing presentation.
  4. Drizzle with Sauce: Drizzle the remaining marinade/sauce over the sliced tuna. Don’t drown it, just a light drizzle is enough.
  5. Garnish: Garnish with thinly sliced green onions.
  6. Serve Immediately: Serve immediately with wasabi paste and pickled ginger, if desired.

Serving Suggestions:

Seared ahi tuna is incredibly versatile and can be served in a variety of ways. Here are a few of my favorite serving suggestions:

  • Over Salad: Serve the seared ahi tuna over a bed of mixed greens with a light vinaigrette dressing. Add some avocado slices for extra creaminess.
  • With Rice: Serve the seared ahi tuna with steamed rice and a side of stir-fried vegetables.
  • In Sushi Bowls: Create your own sushi bowls by layering rice, seared ahi tuna, avocado, seaweed salad, and your favorite toppings.
  • As an Appetizer: Serve the sliced seared ahi tuna as an appetizer with crackers or wonton chips.
  • In Tacos: Use the seared ahi tuna as a filling for tacos. Top with shredded cabbage, avocado crema, and a squeeze of lime juice.

Tips for Success:

Here are a few extra tips to ensure your seared ahi tuna turns out perfectly every time:

  • Use High-Quality Tuna: As mentioned before, using sushi-grade tuna is essential. Look for tuna that is bright red and has a firm texture.
  • Don’t Overcook: The biggest mistake people make when searing ahi tuna is overcooking it. Remember, the center should still be mostly raw.
  • Use a Hot Pan: A screaming hot pan is crucial for achieving a good sear. Make sure the oil is shimmering before adding the tuna.
  • Pat the Tuna Dry: Patting the tuna dry before searing helps it to develop a crispy crust.
  • Season Generously: Don’t be afraid to season the tuna generously with salt and pepper.
  • Let it Rest: Letting the tuna rest for a minute or two before slicing allows the juices to redistribute, resulting in a more tender and flavorful final product.
  • Experiment with Flavors: Feel free to experiment with different flavors and seasonings. Try adding a pinch of cayenne pepper for extra heat, or a squeeze of lime juice for a tangy twist.
Enjoy!
